Answer:
MgO
Explanation:
Mg, which is magnesium, is considered a metal, when paired with Oxygen, which is a gas, it creates magnesium oxide, and the formula itself is a pairing of a metal with a nonmetal
Answer:
You didn't give any options/statements, so I'm just going to give you context on what catalysts does. Catalysts decrease the activation energy needed, allowing more particles for successful reactions.
I know my colleague tried doing an experiment by using hydrogen peroxide as a catalyst and seeing how rates of reactions were affected. It ended up with a stain on our chemistry lab and him re-doing his entire lab.
I am pretty sure the answer is periods. Hope it helps. If not what are the answer choices?
Answer:
Mole percent of 
in solution is 1.71%
Explanation:
Number of moles of a compound is the ratio of mass to molar mass of the compound.
Molar mass of = 110.98 g/mol
Molar mass of 
= 18.02 g/mol
Density is the ratio of mass to volume
So, mass of 60.0 mL of water = 
Hence, 6.50 g of = 
of = 0.0586 moles of
60.8 g of = 
of = 3.37 moles of
So, mole percent of in solution = \frac{n_{CaCl_{2}}}{n_{total}}\times 100% = 
% = 1.71%
Answer:
asexual cell
Explanation:there are mainly 2 types sexual and asexual i would say asexual because they grow without another parent and don't have a nucleus.
