Answer:
Explanation:
Density is found dividing mass by volume. In this case, we treat krypton as a sphere having a volume of 
. Given:
We obtain density of:
This is not a feasible value for a gas like krypton, its radius is actually not 110 pm.
Answer:
Explanation:
When potassium chloride reacts with lead acetate in aqueous medium, it gives white precipitate of lead chloride and potassium acetate in aqueous medium as a product.
As shown in chemical reaction given below:
Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction owing to te fact that energy is a reactant in the equation.
<h3>What is an endothermic reaction?</h3>
An endothermic reaction is one in wioch energy is supplied to the system in order to enable the breakdown of bonds. Hence, the reaction vessel feels cool as energy is withdrawn from the surroundings.
The reaction; Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction since energy is a reactant in the equation.
