Answer:
D
Explanation:
A synthesis reaction is a reaction in which two or more reactants combine to form a given product.
If we look closely at option D, you will notice that sulphur and oxygen combined together to form sulphur dioxide. That is a typical example of chemical synthesis.
Hence;
S + O2 ----->SO2 is a synthesis reaction.
Sodium tritioantimonate(III) and water are the products of the reaction between antimony(III) oxide and sodium hydroxide.
Sb2O3(s)+NaOH(aq)→Na3SbO3(aq)+H2O(l)
Balance the reaction from antimony, sodium, then hydrogen and oxygen.
Sb2O3(s)+6NaOH(aq)→2Na3SbO3(aq)+3H2O(l)
The equation is already balanced.
When each element in a chemical reaction has the same number of atoms and total charge on both the reactants and product sides of the equation, the reaction is said to be balanced. In other words, both sides of the reaction have an equal mass and charge of the components.
Because a chemical reaction is simply an arrangement of the atoms of the supplied elements, a chemical equation must be balanced. For the law of conservation of mass to be followed, the chemical equation must be balanced.

Explanation:
Acid rain slowly dissolves rocks due to chemical reactions between the acid and the minerals in the rock. Differential Weathering: Softer, less resistant rocks wear away at a faster rate than more weather resistant rocks. More exposure to acid rain results in more rapid weathering.
Answer:
17.1195 grams of nitric acid are produced.
Explanation:
Moles of nitrogen dioxide :
According to reaction 3 moles of nitrogen dioxides gives 2 moles of nitric acid.
Then 0.5434 moles of nitrogen dioxides will give:
of nitric acid.
Mass of 0.3623 moles of nitric acid :
Theoretical yield = 22.8260 g
Experimental yield = ?
Experimental yield of nitric acid = 17.1195 g
