The given blank can be filled with endothermic reactions.
The endothermic reactions or processes captivates energy from its surroundings, primarily, but will not always be in the form of heat. A reaction, which requires the input of energy that dissociates a bond will always be endothermic. The best examples of endothermic reactions are evaporation of the liquid, melting cubes, melting or solid salts, and others.
Answer:
35Cl
Explanation:
The number of protons in an element is it's atomic number. Atomic number of Cl is 17. So the element is chlorine. The total sum of the number of protons and neutrons gives the mass number.So mass number of Cl is 17+18=35.So the given atom is Chlorine with mass number
35.
Answer: A) wind and water
Explanation:
The gas that is having lowest density will diffuse faster than other gases. As lesser denser will diffuse more quickly than the one which is more denser. Density is directly proportional to mass of the substance that is more mass of the substance is , more denser it will be. So here the Gas A is having lesser molecular weight than the other gases so it will diffuse more quickly than the other gases.
Gas A; MW = 14.28 g/mol
