Answer:

The empty space between the atomic cloud of an atom and its nucleus is just that: empty space, or vacuum. ... Electrons are thus 'spread out' quite a bit in their orbits about the nucleus. In fact, the wave-functions for electrons in s-orbitals about a nucleus actually extend all the way down into the nucleus itself.

There are no options but the question can be answered based on general understanding of experimentation.

Group A: Control group

Group B: Experimental group

Explanation:

In an experiment, there are two groups viz: the control group and the experimental group. A control group is the group that does not receive any experimental treatment. It is considered the normal group while the experimental group is the group that is subjected to experimental treatment.

N.B: The experimental treatment in this case is the "Oxygen level"

According to the question, out of 20 petri-dishes used to grow bacteria, half (10) of the petri-dishes were placed in a container with normal atmosphere while the other 10 petri-dishes were placed in another container that have double the normal oxygen level. The first group of bacteria labelled GROUP A are the CONTROL GROUP because they were not given any treatment i.e placed under normal conditions while GROUP B are the EXPERIMENTAL GROUP because they are the group that received the experimental treatment (increased oxygen level).

Answer:

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

Explanation:

The periodic table is arranged in order of increasing atomic numbers of elements.

The periodic table is arranged in groups and periods. The elements in the same group have the same number of valence or outermost electrons while the elements in the same period have the same highest energy level.

According to the modern periodic law, the properties of elements are periodic function of their atomic numbers. Hence, the elements are found arranged in order of increasing atomic numbers from left to right in the periodic table.

In mathematics and physics, the right-hand rule is a common mnemonic for understanding orientation of axes in three-dimensional space. Most of the various left- and right-hand rules arise from the fact that the three axes of three-dimensional space have two possible orientations

Explanation:

Answer:

In mathematics and physics, the right-hand rule is a common mnemonic for understanding notation conventions for vectors in 3 dimensions. It was invented for use in electromagnetism by British physicist John Ambrose Fleming in the late 19th century.

When choosing three vectors that must be at right angles to each other, there are two distinct solutions, so when expressing this idea in mathematics, one must remove the ambiguity of which solution is meant.

Answer:

Frequency=?,number of oscillation=57,time=3.

There are two ways to go about this....

You can other use this formula: frequency=number of oscillation/time.

which is 57/3=19Hz.

OR.

You can use this formula:Period is time/number of oscillation.. which is..

3/57=0.053.

and frequency is 1/T....The "T" stands for period.

So since frequency is 1/T then it will be 1/0.053=18.8~19Hz..

The answer is option B.

THE EMPIRICAL FORMULA FOR THE PURE HYDROCARBON IS CH4

Explanation:

A pure hydrocarbon contains carbon and hydrogen

Percentage composition of carbon = 74.5 %

Percentage composition of hydrogen = 25.5

In order to calculate the empirical formula of this hydrocarbon, you follow these couple of steps.

write out the percentage composition and divide by the relative atomic mass of the respective constituents.

Carbon = 74.5 / 12 = 6.2083

Hydrogen = 25.5 / 1 = 25.5

Next is to divide the values by the lowest factor

Carbon = 6.2083 / 6.2083 = 1

Hydrogen = 25.5 / 6.2083 = 4.1

Next is to write the empirical formula:

C H4

In conclusion the empirical formula for the pure hydrcarbon is CH4

Answer:

El volumen del cuerpo es el mismo al comienzo de la experiencia.

Explicación:

El volumen del cuerpo es el mismo al principio porque el volumen no cambia si la temperatura permanece igual. Si cambiamos la temperatura i. mi. Al aumentar la temperatura, las moléculas comienzan a expandirse y se produce un aumento de volumen mientras que cuando disminuimos la temperatura, las moléculas de esa sustancia comienzan a contraerse y el volumen de esa sustancia disminuye. Entonces concluimos que el volumen depende de la temperatura.

Answer:

c) 0.10M NaCl

Explanation:

Options are:

a) 0.20M NaCl

b) Very acidic

c) 0.10M NaCl

d) 0.10M HCl + 0.20M NaOH

e) Slightly acidic.

Based on the reaction:

NaOH + HCl → H₂O + NaCl

You can see than 1 mole of NaOH reacts per mole of HCl producing 1 mole of NaCl

Assuming 1L of 0.20M HCl reacts with 1L of NaOH, moles of both compounds are:

1L * 0.20mol/L = 0.20 moles reacts. That means moles of NaCl produced are 0.20moles in 2L. Molarity of NaCl is:

0.20mol / 2L = 0.10M NaCl

That means, right option is:

At the equivalence point, 0.01 M NaCl is present.

The reaction between NaOH and HCl occurs as follows;

NaOH(aq) + HCl(aq) ------> NaCl(aq) + H2O(l)

Concentration of HCl =  0.20 M

Concentration of NaOH = 0.20 M

Let as assume that the volume of both solutions is 1 L each

Number of moles of HCl = 0.20 moles

Number of moles of NaOH = 0.20 moles

The reaction is 1:1 hence 0.20 moles of NaCl is formed. However, the volume of the solution is now 2L.

Concentration of NaCl = 0.20 moles/2L = 0.01 M

Missing parts;

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is

Select one:

a. 0.20 M NaCl

b. very acidic

c. slightly acidic

d. 0.10 M HCl and 0.20 M NaOH

e. 0.10 M NaCl

Answer:

9.28ml

Explanation:

The density of Lead (Pb) can be calculated using the formula:

Density (g/ml) = Mass (g) / Volume (ml)

According to the question, the empty beaker weighs 245.61 g, then weighed 350.52 g when lead was added to it. This means that the mass of lead in the breaker is: 350.52 g - 245.61 g = 104.91 g

Hence, mass of lead= 104.91g, density of lead= 11.3g/ml

Volume = mass / density

Volume = 104.91/11.3

Volume= 9.284

Hence, the volume of lead is 9.28ml

Answer:

D. The number of protons.

(1) • Balanced Equation : 2HgO (s) ---> 2 Hg (l) + O₂ (g)

• Line a is represented by activation energy, or the smallest amount of energy needed for molecules to undergo a chemical reaction.

• Activated complex is the intermediate state during the conversion of reactants into products. In this case it is represented by Hg----O-----O----Hg. The dashed lines indicate that the bond between Hg and O are breaking and their length is increasing and the dashed line between oxygen atoms indicate that the bond is decreasing and bond formation is taking place.

• This reaction is endothermic as the energy of reactants is smaller than the energy of products.

(2) • Balanced Equation : CH₃Br + OH⁻ ---> CH₃OH + Br⁻

• The hydroxide ion reacts with the bromomethane, resulting in a double replacement reaction. The 'CH₃' in 'CH₃Br' joins with the hydroxide ion to form CH₃OH, while the Br breaks off as an ion.

• Take a look at the energy diagram below.

Answer:

Initially,  endoplasmic reticulum plays a key role in the production of protein, while BiP found in the endoplasmic reticulum contains Lysine , Aspartic acid , Glutamic acid  and Leucine sequence.  All these, cause BiP concentration to remain high in the ER (endoplasmic reticulum) hence retained. Making the lumen always concentrated on BiP.

Explanation:

BiP is known as binding protein, that binds two or more molecules together and is found in the endoplasmic reticulum at the lumen due to the absence of glucose.

The endoplasmic reticulum found in fungi cells, plant cells, animal cells, and protists cells, makes and processes proteins.

Lysine , Aspartic acid , Glutamic acid  and Leucine sequence ensures the protein concentration is protected in the endoplasmic reticulum (ER).

Quantitative measurements are numerical values, they involve amounts and units like measuring things. Qualitative observations appeal to the five senses, like what does the interaction look and sound like

Quantitative measurement about the interactions of matter and energy significantly deals with the representation of numerical values and data.

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

The Qualitative observation of the interactions of matter and energy prominently deals with the concept based on perception. It basically involves all sorts of senses that one should occupy.

For example, how does the interaction between matter and energy looks like in appearances, heared through sounds, and feels through external factors.
