What is the percentage of nitrogen, by mass, in calcium nitrate?.
Answer:
Nitrogen = 17.07%
Explanation:
We are asked to calculate the percentage by mass of nitrogen in Ca(NO3)2.
The molar mass of calcium nitrate is 164,088 g/mol.
In this 164.088 g/mol there are 2 nitrogen atoms.
Molar mass of nitrogen = 14,0067 g/mol
% Nitrogen = molar mass of N/total molar mass of the compound
% Nitrogen =[(2 x 14.0067)/164.088]*100
% Nitrogen = 17.07%

A 7. 298 g sample of copper reacts completely with oxygen, forming a copper oxide. The final mass of the copper oxide is 8. 217 g. What is the formula of the copper oxide?.
The formula of the copper oxide would be [tex]Cu_2O[/tex]
Chemical formulaMass of copper sample = 7.298 g
Mass of final product after reacting with oxygen = 8.217
Mass of oxygen = 8.217 - 7.298
= 0.919 g
Mole ratios
Cu = 7.298/63.546
= 0.115
O = 0.919/16
= 0.057
Cu = 0.115/0.057
= 2
O = 0.057/0.057
= 1
Thus, the formula for the copper oxide will be [tex]Cu_2O[/tex]

A student places a small amount of water in a glass dish and then carefully places a small paperclip on the surface of the water. The paperclip floats. What happens if the student adds a drop or two of dish soap to the water? Check all that apply. The paperclip falls through the water to the bottom of the dish. The soap acts as a surfactant. The soap increases the surface tension of the water. The soap decreases the surface tension of the water.
When soap is added then the paper clip will fall as soap is a surfactant and decreases the surface pressure. The surface strain of water holds the paper.
What is the mechanism of floatation?The paper clip is lighter in weight and floats on the water surface as the density and mass play a major role in floatation. Any addition of substances like soap will lead the clip to fall or sink.
The addition of the soap lessens the pressure of the water surface as it is a surfactant and will affect the surface strain of water.
Therefore, when soap is added, paper clips will fall.

equilibrium and stability quick check
1. a system is at equilibrium. which statement is correct?
a. The rate of the forward reaction equals the rate of the reverse reaction.
b. The system has been disturbed.
c. there are no changes to the system.
d. The concentration of the reactants equal the concentrations of the product.
The concentration of the reactants equal the concentrations of the product.
At equilibrium the reaction neither moves forward nor backwardSo concentration remains constant.In the chemical equilibrium, the system has no observable changes. It is the state of the equal concentration state of the reactant and the products.
What happens in the chemical equilibrium?It is the dynamic state of the reaction in which the concentration of the chemical reactants and the products of the reaction are in a constant state and the amount does not change.
The chemical reaction does not move forward or backwards unless a disturbing or stressed condition is given to the system.
Therefore, option d. the concentration of the reactants and the products are equal.

Lithium-7
Explanation:
By carefully inspecting the diagram we can see three different sub-particles.
1) Electrons (-vely charged, outside the nucleus)
2) Protons (+vely charged, Inside nucleus)
3) Neutrons (uncharged, Inside nucleus)
Mass Number:
Mass number is the number of protons and neutrons present in the nucleus of an atom.
Therefore, in our problem there are 4 neutrons and 3 protons.
So, the mass number is 7.
Atomic Number:
Atomic number is the number of protons present in the nucleus. This number shows the identity of an atom. If you go through the periodic table you will find that the atomic number 3 is for Lithium.
Result:
Lithium-7
