Answer:
CaCl2, Li2S, AlCl3, AlCl3, K2S
Explanation:
When figuring out which is a better conductor of electricity you want to look at which has the largest yield of dissociated ions.
Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present
Answer:
option D= it makes the reaction harder to start.
Explanation:
Activation energy:
It is the minimum amount of energy required by chemical specie to start the chemical reaction.
Explanation:
The activation energy is inversely related to the rate of reaction. The higher the activation energy the slower will be the reaction rate.
Molecules are colloid with each other and gain kinetic energy if this energy is higher than the transition state energy then molecules easily undergo the chemical reaction. Because molecules easily overcome the barrier i.e transition state.
When the kinetic energy is lower than molecules can not pass the barrier. They require the input which is called activation energy to pass the barrier.
The higher the activation energy, the difficult for the reaction to proceed. Catalyst are used to lower the activation energies because in this way lower will be the transition state, and higher will be the reaction rate.
