Answer:
B
Explanation:
Can't really explain it sorry buy heating the solvent tends to increase the solubility
The step that would increase the solubility of the gas in the liquid solvent is to increase the temperature of the gas and liquid.
What is solubility?Solubility is the mixing of any substance into another substance and the fully mixing of the ions of the substance to another substance's ions.
Solubility depends upon temperature, increasing temperature increase the solubility.
In the mixing of gas and liquid, the liquid is solvent and gas is solute, always.
Thus, the correct option is B.

Iron is denser than helium.
True or false
Explanation:
Elements heavier than Helium are synthesized in a number of environments. For elements that are lighter than Iron, those elements are synthesized during various phases in the evolution of massive stars. For elements heavier than Iron, one needs quite a bit of energy input to form these heavy elements.
1. A chemical equation is balanced when *
Answer:1 Answer. A chemical equation is balanced when the number of each kind of atom is the same on both sides of the reaction,,
Answer:
If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.

1. Based on the equation, Mg+2NaF => MgF2 + 2Na , if 23.56 grams of magnesium reacts with sufficient sodium
fluoride, how many grams of sodium will be produced?
Since we have sufficient sodium fluoride (NaF), the magnesium (Mg) will be our limiting reactant, and we will use its coefficient in the balanced equation to determine our molar ratio between the product of interest which, in this case, is sodium (Na).
We are given the mass of magnesium, 23.56 grams, which we must convert to moles by dividing the mass by the molar mass of magnesium: (23.56 g)/(24.305 g/mol) = 0.9693 mol Mg.
According to the balanced equation given, the molar ratio between sodium and magnesium is 2:1. That is, for every 2 moles of Na that are produced, one mole of Mg is consumed or reacted. The upshot is that the number of moles of sodium produced will be double the number of moles of Mg reacted. Since we have 0.9693 moles of Mg available to react, we will obtain (0.9693 mol Mg)(2 mol Na/1 mol Mg) = 1.939 mol Na.
Finally, we multiply our moles of sodium by the molar mass of sodium to get the mass: (1.939 mol Na)(22.99 g/mol) = 44.57 grams Na.
So, 44.57 grams of sodium will be produced.

92.12 kJ of heat is required to convert 58.40 g of gold from liquid to gas phase. What is the heat of vaporization of gold in J/g?
Answer:
The heat of vaporization of the gold sample is 1577.397 joules per gram.
Explanation:
The latent heat of vaporization of gold ([tex]h_{v}[/tex]), in kilojoules per gram, is the heat required by a unit mass of gold to transform the material from liquid to gas:
[tex]h_{v} = \frac{E}{m}[/tex] (1)
Where:
[tex]E[/tex] - Energy required for vaporization, in joules.
[tex]m[/tex] - Mass, in grams.
If we know that [tex]E = 92120\,J[/tex] and [tex]m = 58.40\,g[/tex], then the heat of vaporization of the gold sample is:
[tex]h_{v} = \frac{E}{m}[/tex]
[tex]h_{v} = 1577.397\,\frac{J}{g}[/tex]
The heat of vaporization of the gold sample is 1577.397 joules per gram.
What experimental evidence led Rutherford to conclude the following: (a) The nucleus of the atom contains most of the atomic mass. The nucleus of the atom contains most of the mass since only a collision with a very dense, massive object would cause an alpha particle to be the source. (b) The nucleus of the atom is positively charged. The positive alpha particles their initial flight indicating that the nucleus of the atom is also positively charged. (c) The atom consists of mostly empty space. Most alpha particles pass through the gold foil leading to the conclusion that the atom is mostly empty space.
Answer:
See Explanation
Explanation:
The experiment of Ernest Rutherford involved the bombardment of a thin gold foil with alpha particles from a radioactive source. A zinc sulphide screen was used to follow the movement of the alpha particles.
It was discovered that most of the alpha particles followed a straight path through the gold foil. Some of them were scattered through large angles and few were even scattered in the backward direction.
Since alpha particles were heavier than electrons, they must have been deflected by very strong forces.
These experimental evidences led to the conclusions stated in the question.

Suppose you have 1000 lb of waste copper (II) oxide sitting in the basement of your factory. Do you see a problem with sending it to a landfill?
Answer:
Yes.
Explanation:
Yes, we have a problem with sending it to a landfill of copper oxide because it has harmful effect on the health of humans as well as more weight of the copper oxide. Copper oxide usually found in powder form which can easily be inhaled that causes death of the cell due to toxic effect on the mitochondria and lysosomes of the cell. It makes problem of health in carrying the copper oxide from the basement of the factory to the landfill region due to its power form so we can say that it can do problems to human health while carrying from one place to another.
There is a series of nitrogen oxides with the general formula N?O?. What is the empirical formula of one that contains 63.66% nitrogen?
Answer:
N₂O
Explanation:
Empirical formula is defined as the simplest whole number ratio of atoms presents in a molecule
For a nitrogen oxide that contains 63.66% of nitrogen, the percent of oxygen must be:
100-63.66 = 36.34% Oxygen
This percent is the percent in mass. To solve this question we must convert the mass of each atom to moles in order to find the simplest whole number ratio:
Moles of the atoms:
N = 63.66g * (1mol / 14g) = 4.547 moles N
O = 36.34g * (1mol / 16g) = 2.271 moles O
The ratio N:O is:
4.547 moles N / 2.271 moles O = 2
That means there are 2 atoms of N per atom of O and the empirical formula is:
