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
Your answer would be 250,000

8.00 g
The law of conservation of mass
Explanation: -
When magnesium burns in air it combines with oxygen to form magnesium oxide.
The mass of the product is the mass of the magnesium oxide.
The mass of the reactant is the mass of the magnesium + mass of the oxygen.
Since matter cannot be created or destroyed according to the law of conservation of mass,
Mass of Magnesium oxide formed = mass of magnesium reacted + mass of oxygen reacted
= 3.00 g + 5.00 g
= 8.00 g
