A cubic container is filled up with an unknown liquid whose density is 0.180 g/cm3. The side lengh of the container is 5.00cm. Whaf is the mass of this liquid??
Answer:
THE MASS OF THE LIQUID IS 22.5 g
Explanation:
Density = 0.180 g/cm3
Side length = 5 cm
Mass = unknown
To calculate the mass of the liquid, we use the formula:
Mass = density * volume
Volume of a cube or cuboid container = l^3
Volume = 5 ^3 = 125 cm3
So therefore, the mass of the liquid is:
Mass = 0.180 * 125
Mass = 22.5 g
In conclusion, the mass of the liquid in the container is 22.5 g
Why is environmental science more than just ecology or biology?
Generally speaking, environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things.

How to know what gases have more effusion?
Answer:
If you have ever been in a room when a piping hot pizza was delivered, you have been made aware of the fact that gaseous molecules can quickly spread throughout a room, as evidenced by the pleasant aroma that soon reaches your nose. Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target.

seconds?
O A. 0.053 s
B. 19 Hz
C. 171 Hz
O D. 60 s
SUBMIT
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.
Thank you for the question I hope it helps you

Hydrogen (h) atoms have one electron and exist as diatomic molecules (h2). Helium atoms have 2 electrons and exist only as a single helium atom. Explain why they differ in this way
Answer:
Explanation:
Hydrogen atoms have an electronic configuration of 1s¹. This indicates that they require one more additional hydrogen in order to complete it octet structure and before they can form a reaction.
Helium have an electronic configuration of 1s², which is a noble gas. In noble gas, their octet structures are complete. As such they do not require additional electron before they can form a reaction.
BiP is found in high concentration in the lumen of the ER but is not present in significant concentrations elsewhere in the cell. How do you think this condition is established and maintained
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).

what are thermosetting plastics???
Explanation:
Thermosetting plastic are made up of long chain of molecules which are cross-linked and can be moulded into different shape and size.
Answer:
Hey!
THERMOSETTING PLASTICS are plastics or polymers that become IRREVESIBLY SET/RIGID when it has been heated and cooled...
Explanation:
This means that if you heat up a thermosetting plastic, you only have one chance to mould it or shape it before it cools down...if not you cannot correct this and will have to start again! Which WILL be sad!

Charlie is frying an egg in a pan located over a gas burner. He develops a model to determine the energy produced by the flame in the gas
burner by calculating the energy absorbed by the egg. Which assumption will Charlie need to make in order for his model to be considered a
closed system?
A. Heat flows from the egg to the surroundings.
O
B. Heat flows from the pan to the surroundings.

C. No heat is lost from the flame or the egg to the surroundings.
OD. The egg receives heat from the flame and the surroundings.
A closed system is one in which there is no exchange of materials or energy with the surroundings hence the correct assumption is that "No heat is lost from the flame or the egg to the surroundings."
Another name for a closed system is an isolated system. In such system, there is exchange of material or energy between the system and the surroundings.
In this case, the system comprises of the pan and the eggs. If the system is to be a closed system then " No heat is lost from the flame or the egg to the surroundings."

Indicate whether each of the following compounds dissolves in water to give ions, molecules, or both.
1. NaCl
2. HF
3. CH3CH2OH (ethanol)
4. HI
5. Weak electrolyte
6. Nonelectrolyte
7. Strong electrolyte
Answer:
The answer is in the explanation
Explanation:
An ion is defined as a particle that is positive or negative charged.
In water, strong electrolytes dissociates completely to produce ions. Weak electrolytes dissolves partially. One part in ions and the other still as the complete molecule. A nonelectrolyte doesn't dissociates in any way!
1. NaCl . STRONG ELECTROLYTE. Dissociates in ions
2. HF . WEAK ELECTROLYTE. Dissociates partially producing both molecules and ions
3. CH3CH2OH (ethanol) . NONELECTROLYTE. Doesn't dissociates producing just molecules.
4. HI . STRONG ELECTROLYTE. Dissociates completely in ions.
5. Weak electrolyte . Dissociates partially giving ions but also molecules
6. Nonelectrolyte . Only give molecules.
7. Strong electrolyte. Gives only ions.
If you want to cause an object to move, what should you do?
Answer:
For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest.

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is
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:
c) 0.10M NaClAt 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;

(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.
