Answer:
Explanation:
Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (all atoms with six protons are carbon atoms), the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

We need an equation that would relate the concentration of the original solution to that of the desired solution. To solve this we use the equation expressed as follows,
M1V1 = M2V2
where M1 is the concentration
of the stock solution, V1 is the volume of the stock solution, M2 is the
concentration of the new solution and V2 is its volume.
M1V1 = M2V2
0.266 M x V1 = 0.075 M x 150 mL
V1 = 42.29 mL
Therefore, we need about 42.29 mL of the 0.266 M of lithium nitrate solution to make 150.0 mL of the 0.075 M lithium nitrate solution.
Answer: S8 + O2 → S8O2: not 100% sure
Explanation:
A balanced chemical equation happens when the quantity of the particles is required on the reactants side is equivalent to the quantity is the molecules in the items side.
Answer:
Amount of gas
Explanation:
The combined gas law has to do with pressure, volume, and temperature. All of them can be a variable that you have to solve for. However, amount of gas is not a variable you can solve for, which means it must remain constant.
