Na₂O + HCl → NaCl + H₂O
Does the equation above satisfy the law of conservation of matter?
No, since there are two sodium atoms as reactants but only one sodium atom as product
<u><em>Explanation</em></u>
According to the law of mass conservation of matter the total number of atoms of reactant must be equal to total number of product.
For equation given to satisfy the law of conservation of matter you need to balance the equation as below
Na₂O + 2HCl → 2NaCl + H₂O
<h2>Nuclear Fission and Nuclear Fusion - Option C</h2>
Nuclear fission and nuclear fusion both of these processes can provide energy. Nuclear fission is the process in which heavy nucleus splits into smaller parts. When they split into smaller particles then it releases energy.
On the other hand, nuclear fusion is the process in which small particles fuse together to form a heavy nucleus. With the formation of heavy nucleus, it also provides energy.
Therefore, both these processes release or provide energy.
Water, air, and even ice are fluids because they tend to flow from one place to another due to the force of gravity.
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
