What is the total number of moles of H2SO4 needed to prepare 5.0 liters of a 2.0 M solution of H2SO4
forsale [732]
The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol

brilliants [131]

Answer:

The correct answer is - They are mechanical waves.

Explanation:

Atomic bombs after detonated they send a shock wave that makes a movement of particulate matter that leads to transfer of a high amount of energy that superheats the air medium that travels as a mechanical shock wave.

The shock wave that is sent out by a detonated atomic bomb is a longitudinal mechanical wave that transfers the energy to the neighboring particles of the air.

Which of the following could be the rate equation for a first order reaction? please help this is timed
wel

Rate = k[A] = first order reaction

<h3>Further explanation</h3>

Given

Rate law

Required

A first-order reaction

Solution

The rate law : equation for the rate of chemical reaction

For reaction

aA + bB ⇒ C

The rate : r = k[A]ᵃ[B]ᵇ

The sum of exponents(a+b) is the reaction order

From the choice :

a. a+b = 2, second order reaction

b. a+b = 3, third order reaction

c. a+b = 4, fourth order reaction

d a+0 = 1, first order reaction
