Answer:
2:8
Explanation:
The reaction equation is a given as:
2C₄H₁₀ + 130₂ → 8CO₂ + 10H₂O
From the reaction equation, the mole ratio is 2:8
Butane is C₄H₁₀
Carbon dioxide CO₂
From the reaction;
2 moles of butane will produce 8 moles of carbon dioxide
Answer:
<h2>5.35 </h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
We have
We have the final answer as
<h3>5.35 </h3>

Answer:
c. contraction
Explanation:
Heating will cause substances to expand, or change their state (like solid to liquid) or it may be a chemical reaction.
Answer:
Al2(SO4)3 and Mg(OH)2
Explanation:
1. Al has a charge of 3-, and SO4 of 2-
when you cross multiply the charges you get
Al2 and (SO4)3
*the reason theres a bracket around the sulfate ion is that the charge 3 is not for oxygen only, but the entire sulphate ion*
Hence, Al2(SO4)3
2. Mg has a charge of 2- and OH of 1-
again cross multiply
Mg (you dont need to add the 1) and (OH)2
again, the bracket around OH means the charge appiles to Oxygen AND hydrogen
hence, Mg(OH)2
