Answer:
90.37 g
Explanation:
From Avogadro Number,
1 mole of every substance contains a particle number of 6.02×10²³
From the question,
1 mole of CH₄ contains 6.02×10²³ molecules.
But,
1 mole of CH₄ has a mass of 16 g
Therefore,
16 g of CH₄ contains 6.02×10²³ molecules
Then,
Y g will contain 3.4×10²⁴ molecules
Solve for Y
Y = (16× 3.4×10²⁴)/(6.02×10²³)
Y = 90.37 g
Answer:
The activation energy of an endothermic reaction
A) must be greater than the required △H
Explanation:
endothermic reaction : Are those which absorbs heat from the surrounding
.<em>This energy provide activation energy for the reaction to occur</em>.
So activation energy becomes more than enthalpy.
This is false, they have intermediate properties between suspension and true solution
Answer:
the dividend yield is 4%
Explanation:
The computation of the dividend yield is as follows:
Dividend yield = Dividend per share ÷ current share price per share
= ($0.20 × 4 quarters) ÷ $20
= $0.80 ÷ $0.20
= 4%
hence, the dividend yield is 4%
The same is determined by applying the above formula
