Work completed : 15 J

<h3>Further explanation </h3>

Work is the transfer of energy caused by the force acting on a moving object  

Work is the product of force with the displacement of objects.  

Can be formulated  

W = F x d  

W = Work, J, Nm  

F = Force, N  

d = distance, m  

Force=F= 5 N

Distance=d=3 m

Work :

\tt W=5\times 3\\\\W=15~J

A solution of phosphoric acid was made by dissolving 10.0 g of H3PO4 in 100.0 mL of water. The resulting volume was 113 mL. Calc
rodikova [14]

Explanation:

Mass of solute = 10.0 g

mass of solvent(water) = m

Volume of solvent( water) = v = 100.0 mL

Density of water= d = 1 g/cm^3=1 g/mL

1 mL= 1 cm^3

m=d\times v=1.0 g/mL\times 100.0 = 100.0 g

Mass of solution(M) = Mass of solute + mass of solvent

M = 10.0 g + 100.0 g = 110.0 g

Volume of the solution = V = 113 mL

Density of the solution = D

D=\frac{M}{V}=\frac{110.0 g}{113 mL}=0.9734 g/mL

The density of the solution is 0.9734 g/ml.

Moles of phosphoric acid = n_1=\frac{10.0 g}{98 g/mol}=0.1020 mol

Moles of water  = n_2=\frac{100.0 g}{18g/mol}=5.556 mol

Mole fraction of phosphoric acid =\chi_1

\chi_1=\frac{n_1}{n_1+n_2}=\frac{0.1020 mol}{0.1020 mol+5.556 mol}

\chi_1=0.01803

Mole fraction of water =\chi_2

\chi_2=\frac{n_2}{n_1+n_2}=\frac{5.556 mol}{0.1020 mol+5.556 mol}

\chi_2=0.9820

[Molarity]=\frac{\text{Moles of solute}}{\text{Volume of solution(L)}}

Moles of  phosphoric acid = 0.1020 mol

Volume of the solution = V = 113 mL = 0.113 L ( 1 mL = 0.001 L)

Molarity of the solution :

=\frac{0.1020 mol}{0.113 L}=0.903 M

[Molality]=\frac{\text{Moles of solute}}{\text{Mass of solvent(kg)}}

Moles of  phosphoric acid = 0.1020 mol

Mass of solvent(water) = m =100.0 g = 0.100 kg ( 1 g = 0.001 kg)

Molality of the solution :

=\frac{0.1020 mol}{0.100 kg}=1.02 mol/kg

Describe a method to investigate how the temperature changes when different masses of ammonium
rewona [7]

Answer:

Decrease temperature with increase in ammonium nitrate concentration.

Explanation:

The temperature changes when different masses of ammonium nitrate are dissolved in water because the ammonium nitrate takes energy from the surrounding water environment for the breaking of ionic bonds as a result the temperature of water decreases. When more concentration of ammonium nitrate is added to water, more decrease occur in temperature of water and the water becomes cold.

PLEASE HELP!!!!!!!!!
KonstantinChe [14]

Answer:

Option "C" is the correct answer to the following question.

Explanation:

Given:

Pressure in an automobile tire (P) = 1.88 atm

Temperature (K) = 25°C = 273 + 25 = 298 Kelvin

New temperature (K1) = 37°C = 273 + 37 = 310 Kelvin

Find:

New pressure in an automobile tire (P1) = ?

Computation:

\frac{P}{K}= \frac{P1}{K1} \\\\\frac{1.88}{298}= \frac{P1}{310}\\\\1.9557

New pressure in an automobile tire (P1) = 1.9557

New pressure in an automobile tire (P1) = 1.96 (Approx)

CHEMCIAL TECHNOLOGY QUICK CHECK which activity would be considered resource extraction? eating beef raising cattle eating deer h
Harlamova29_29 [7]

Hunting deer can be considered resource extraction. It involves the loss of biodiversity.

<h3>What does resource extraction mean?</h3>

Resource extraction refers to the usage of fundamental resources (biodiversity resources) from the environment.

Hunting deer is considered a resource extraction activity because this activity involves the loss of biodiversity.

Biodiversity is a fundamental issue for the health (homeostasis state) of the whole ecosystem.
