Answer:
1.1 g Na2SO4
Explanation:
First convert mL to L. Then multiply by the Molarity to get moles, then multiply by the molar mass to get grams.
15 mL x 1 L x 0.50 mol Na2SO4 x 142 g = 1.1 g
10^3 mL 1 L mol Na2SO4
Answer:
Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Explanation:
Answer:
Explanation:
CH₃Br+NaOH⟶CH₃OH+NaBr
It is a single step bimolecular reaction so order of reaction is 2 , one for CH₃Br and one for NaOH .
rate of reaction = k x [CH₃Br] [ NaOH]
.008 = k x .12 x .12
k = .55555
when concentration of CH₃Br is doubled
rate of reaction = .555555 x [.24] [ .12 ]
= .016 M/s
when concentration of NaOH is halved
rate of reaction = .555555 x [.12] [ .06 ]
= .004 M/s
when concentration of both CH₃Br and Na OH is made 5 times
rate of reaction = .555555 x .6 x .6
= 0.2 M/s
