Answer: I believe it's convection
Good luck and I hope this helps!!
Answer:
B) One way of solving this is to use dimensional analysis and cancel out grams to find volume.
A) density over mass is volume. Mass is 84.7 g and volume is 49.6 cm cubed
Explanation:
4KO₂ + 2CO₂ → 2K₂CO₃ + 3 O₂
The two chemicals that have a molar ratio of 3:4 is in equation above O₂ and KO₂
<em><u>explanation</u></em>
The molar ratio is the ratio between the amount in moles of two compounds that are involved in a chemical reaction.
In the equation above the mole ratio is determined by examining coefficient ( <em>number in front of the formula</em>)
the coefficient of O₂ is 3 while that of KO₂ is 4 therefore the mole ratio of O₂:KO₂ is 3:4

Answer:
Single replacement
Explanation:
Chemical equation:
2Al(NO₃)₃ + 3Ca → 3Ca(NO₃)₂ + 2Al
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
All other options are incorrect because,
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Combustion reaction:
Reaction in substance react with oxygen and form carbon dioxide and water.
