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.
Answer:
V₂ = 457.49 mL
Explanation:
Given that,
Initial volume, 
Initial temperature, 
Final temperature, 
We need to find the final volume of the gas. The relation between the volume and the temperature of the gas is given by :

Put the respected values,

So, the final volume of the gas is equal to 457.49 mL.

Answer: Temperature increase
Explanation:
Endothermic reaction means the absorb of heat from the surrounding. So when heat is absorbed from the surrounding then the temperature of the reaction will increase
Climate change is likely causing parts of the water cycle to speed up as warming global temperatures increase the rate of evaporation worldwide. More evaporation is causing more precipitation, on average.
