The balanced equation for the reaction between Mg and O₂ is as follows
2Mg + O₂ --> 2MgO
stoichiometry between Mg and O₂ is 2:1
number of Mg reacted - 4.00 mol
if 2 mol of Mg reacts with 1 mol of O₂
then 4.00 mol of Mg requires - 1/2 x 4.00 = 2.00 mol of O₂
then the mass of O₂ required - 2.00 mol x 32.0 g/mol = 64.0 g
64.0 g of O₂ is required for the reaction
Answer:
B. increase the distance between the objects
Explanation:
A) increase the mass of one of the objects
3.6 moles 
required when each quantity of reactant completely reacts.
The ratio of the mole quantities of any two compounds present in a balanced chemical reaction is known as the mole ratio. A reaction's product yield can be predicted using mole ratios, as can the amount of reactant required to produce a specific amount of result.
The balanced chemical equation is :
(l) → 
(g) + 
(g)
Given is = 2.6 mol 
As we see, 3 moles of reacts with 4 moles of .
Therefore,
n( ) = n( ) × 
n( ) = 
n( ) = 3.6 moles.
Therefores, 3.6 moles required when each quantity of reactant completely reacts.

Solid gold. 10 carat indicates gold purity is not 100%. For 24 karat gold is pure gold.
Answer:
Yes, the data supports the researchers hypothesis.
Explanation:
From the given data, in all the cases except the fanning event in females, the fish parents which was fed full ration appeared.
Take for example, 30.7 mouthing events in males given full ration as opposed to 24.5 events when they were fed on half ration.
