magnesium oxide is: MgO (right side)
so the left side is: Mg + O2
for the equation to be balanced there must be two oxygens on both sides
Mg + O2 = 2MgO
but now the magnesium is uneven, so there must be two magnesiums on each side
the answer is: B) 2Mg + O2 = 2MgO

Answer: Inorganic chemistry
Explanation:
Inorganic chemistry can be defined as the branch of chemistry which studies the behavior of the inorganic compounds. Inorganic compounds are those compounds which lack carbon hydrogen bonding. The carbon monoxide, carbon dioxide, sodium chloride and water are the examples of inorganic compounds. This branch also studies the effect of these chemical compounds on the living things. The water and salts are chemicals which regulate the chemical and physiological reactions in the body.
Answer:
Explanation:
Hello.
In this case, since the acid is monoprotic and the KOH has one hydroxyl ion only, we can see that at the equivalence point the moles of both of them are the same:
Thus, since we are given 1.70 g of the acid, we compute the moles of acid that were titrated:
Which equal the moles of KOH. In such a way, since the molarity is defined as moles over liters (M=n/V), the liters are moles over molarity (V=n/M), thus, the resulting volume is:
