Answer:

Value of expressions in scientific notation = 15.86 x 10⁻¹⁰

Explanation:

Given expressions:

2.600 x 10⁻⁵ x 6.100 x 10⁻⁵

Find:

Value of expressions in scientific notation

Computation:

2.600 x 10⁻⁵ x 6.100 x 10⁻⁵

2.600 x 6.100 x 10⁻⁵x 10⁻⁵

15.86 x 10⁻⁵ x 10⁻⁵

We know that;

qᵃ x qᵇ = q⁽ᵃ⁺ᵇ⁾

So,

15.86 x 10⁽⁻⁵⁻⁵⁾

15.86 x 10⁽⁻¹⁰⁾

Value of expressions in scientific notation = 15.86 x 10⁻¹⁰

A chemist wants to observe the following reaction:
stiv31 [10]

It take more energy to break the bonds of the reactants and less energy is given off when the product bonds are formed.

<h3>What is Energy?</h3>

Energy is defined as the ability to do work. Work is done in the breaking or formation of bonds.

The standard Enthalpy (ΔH) of water which was formed in the given reaction is negative.

ΔH= Δproduct - Δreactant

This means that the energy to break the bonds of the reactants is more.

Hydrogen gas is collected over water at 21 degrees Celsius. At 21 degrees Celsius the vapor pressure of water is 18.7 torr. If t
Alinara [238K]

Answer : The pressure of hydrogen gas is, 739.3 torr

Explanation :

As we are given:

Vapor pressure of water = 18.7 torr

Barometric pressure = 758 torr

Now we have to calculate the pressure of hydrogen gas.

Pressure of hydrogen gas = Barometric pressure - Vapor pressure of water

Pressure of hydrogen gas = 758 torr - 18.7 torr

Pressure of hydrogen gas = 739.3 torr

Therefore, the pressure of hydrogen gas is, 739.3 torr
