I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
When an object of mass 2Kg and applied force is 10N then acceleration is 5 m/s/s.
<h3>What is
Newton's second Law?</h3>
Newton's second Law of motion will be represented as:
F = m.a, where
- F = force
- m = mass of object
- a = acceleration
Acceleration for the first row will be calculated as:
Acceleration for the second row will be calculated as:
Mass for the third row will be calculated as:
Mass for the forth row will be calculated as:
Force for the fifth row will be calculated as:
Hence, acceleration of the object whose mass is 2kg and force on that object is 10N is 5m/s/s.

Calcium oxide is known as lime and is one of the top 10 chemicals produced annually by thermal decomposition of limestone. .Over time, this reacts with carbon dioxide in the air to form crystals of calcium carbonate, which lock the sand grains together to form a hard rock-like material.
Answer:
The correct option is;
24 moles
Explanation:
Here, we have the reaction as follows;
Sn(s) + 2HF(g) → SnF₂ (s) + H₂ (g)
Therefore, one mole of Sn reacts with 2 moles HF to form one mole of SnF₂ and one mole of H₂
Molar mass of H₂ = 2.01588 g/mol
Therefore, the number of moles of H₂ in 48 grams of H₂ is given by the relation;
Since one mole each of SnF₂ and H₂ are produced, the number of moles of SnF₂ produced = 24 moles.
The number of moles of SnF₂ that will be produced is 24 moles.
