<span>The most significant factor that controls the development of soil is B. climate. Depending on what the climate and the weather are like in a particular area, the soil will be either developed and healthy and fertile, or it won't if the conditions are too harsh. If the weather is nice, usually the soil will form which will be suitable for crops and agriculture, but if it's too hot or too cold, the soil won't be used for such things as it won't be fertile.</span>
I think the answer is B. I really don't remember but im pretty sure its that one.
mass Hydrogen=9.376 g
<h3>Further explanation
</h3>
Reaction
2H₂+O₂⇒2H₂O
mass H₂ = 10 g
mol H₂(MW=2 g/mol) :
10 : 2 = 5
mass O₂=5 g
mol O₂(MW=32 g/mol) :
5 : 32 = 0.156
O₂ limiting reactant
mol H₂: mol O₂ = 2: 1, so mol H₂ :
2 x 0.156 = 0.312
mol H₂ :
5 - 0.132 =4.688
mass of H₂ :
4.688 x 2 =9.376 g

Answer:</h2>
- Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas.
example: Acetic acid
- Bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery;
example: sodium bicarbonate
