Activation energy is what kind of chemical reaction that absorbs energy

Chemistry
1 answer:
seraphim [82]3 years ago
3 0

Activation energy is the energy required by reactants to undergo chemical reaction and given products

Every reactant has some internal energy (sum of all kind of energy like kinetic energy, potential energy, mechanical energy, chemical energy etc). It needs some extra energy to undergo chemical reaction which is activation energy

All kinds of reaction whether exothermic or endothermic needs activation energy

Threshold energy = internal energy + activation energy

Which of the following is the displacement from point P to point W?
IRINA_888 [86]
<span>C represents the displacement ONLY if it is the VECTOR arrow from P to W. 
Usually if the arrow on the diagram has JUST a letter listing, that letter stands for the SIZE or LENGTH of the VECTOR arrow. In order to have the letter represent the VECTOR, itself, it must have a symbol of a "half arrow" placed above it.</span>

Calculate each of the following:<br> (a) Mass fraction of Cl in calcium chlorate
Marianna [84]

Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.

<h3>What is meant by a mass fraction?</h3>

Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.

The formula for a mass fraction (w) is given as,

Mass fraction (w) = mass ÷ total mass

Given,

Mass of chlorine = 35.453 grams per mole

The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole

Substituting and solving the values above as

w = mass of chlorine ÷ total mass of calcium chlorate

w = 35.453 ÷ 206.98

w = 0.171

Therefore, the mass fraction of Cl in calcium chlorate is 0.171.
