Got it right on edge 23

To convert from L to ml, we move three spaces to the right and the decimal place moves three places.

Our task here is to convert 600 L to mL. we have to remember that to convert from L to ml, we have to multiply the value in L by 1000

In other words, the value 1000 is known as the conversion factor.

When we do this, we move the decimal place three places to the right to have 600000.00mL

Answer:

The answer would be: An atom’s nucleus occupies very little of the atom’s volume but contains most of its mass

Explanation:

The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom.

Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.

Refer to https://en.wikipedia.org/wiki/Atomic_nucleus for further understanding

Answer:

Explanation:

The glass (which does not crystallize even though it is accepted) of a window is NOT a mineral, since it is neither a substance of natural origin (although it is manufactured from natural components) nor does it have a defined crystalline structure, that is, the atoms they are not arranged in an orderly and regular way along axes and planes forming flat faces that keep a symmetry.

Remember that a mineral is defined as a solid, inorganic, homogeneous substance, of natural origin, with a crystalline structure and a determined and well-defined chemical composition within narrow margins and that has regular and characteristic physical properties.

Explanation: No, glass is not a mineral. ... Definable chemical composition: SiO2 *Actually, most industrially-produced glass is not pure silica, but having impurities is still a definable chemical composition so this part of the definition is ok. Orderly arrangement of atoms in a lattice: NO.

Answer:

Option C.

Explanation:

The arrangement of electrons in their orbital follows certain rules.

The Hund's rule practically explained how electrons are distributed in their orbitals.

The Hund's rule states that electrons distributed among the orbitals of the same shell singly (without partner) before pairing occurs.

In the filling of these electrons in their orbitals, we fill in the electron without pairing first because electrons tends to repel each other before filling with the opposite spin as shown in the attached photo.

Answer:

Two of the three salts are soluble.

One of the three salts is soluble.

Explanation:

One or two of the three salts would be soluble in water depending on if the water is cold or hot.

According to the solubility rules of chloride salts, all chlorides are soluble in cold water except for those of silver (Ag), lead (Pb), and mercury (I) (Hg).

This thus means that both AgCl and [tex]PbCl_2[/tex] would be insoluble in cold water while LiCl would be soluble.

[tex]PbCl_2[/tex] is, however soluble in hot water.

Hence, in cold water, one of the three salts (LiCl) would be soluble, while in hot water, two of the three salts (LiCl and [tex]PbCl_2[/tex]) would be soluble.

Answer:

Metal

Element: Calcium

Valency: 2

Explanation:

To find the element, let's use the periodic table. (Look below)

We already went past 3 shells, just need the 2 electrons after it.

Just skip to the 4th row and count 2 to the right

We end up at Calcium.

Calcium is a metal and we're also on the alkaline earth metals column.

Calcium will need to lose 2 electrons to reach stability, so the valency is 2.

Answer:

b

Explanation:

In the given scenario, the mass lost by the copper electrode is gained by the zinc cathode. The correct option is B.

The law of conservation of mass asserts that mass is neither created nor destroyed in a chemical reaction.

As electrons are lost at the anode, metal cations construct and dissipate into the solution, reducing the anode's mass through corrosion. The anode's lost electrons attract to the positively charged cathode and flow through the wire.

Thus, the correct option is B.

Answer:

A few of the positive particles aimed at a gold foil seemed to bounce back.

Explanation:

Rutherford's experiment took the search for the structure of the atom a step further. In this experiment, a narrow beam of alpha particles emitted from a source was used to bombard a thin gold foil.

The scattering of the alpha particles was detected by a movable ZnS screen. It was found that most of the alpha particles followed a straight path through the gold foil but some were scattered through large angles and some even scattered backwards.

Following this experiment, Rutherford decided on his planetary model of the atom in which the nucleus is at the core of the atom with electrons moving round the nucleus in orbits. Rutherford was awarded a Nobel prize for this work.

Answer:

Lavoiser proposed a theory in charge of writing the combustion correctly, denying the phlogiston.

Lavoiser said that combustion is carried out in a medium where there is oxygen, giving as a product water and carbon dioxide.

This combustion results in the decrease in the volume of the material that burns.

Furthermore lavoiser discovered the importance of oxygen in animal respiration.

Explanation:

Lavoisier argued that if or if the presence of oxygen must be present, it is an irreversible and spontaneous process.

What is the importance of nitrogen for plants?

Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes. Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.

Answer:

Nitrogen is vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide(i.e.,photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.

Answer:

69.66 g

Explanation:

We have the following from the question;

Density of the substance = 5.4 g/ml

Volume of substance = 12.9 ml

Mass of substance= the unknown

Since we have both density and volume of the substance, the question must be for us to obtain the mass of the substance, hence;

Density= mass/volume

Mass= Density × volume

Mass = 5.4 g/ml × 12.9 ml

Mass= 69.66 g

Explanation:

A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon.

If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.
