(Explanation problem) Can you list two ways in which the biosphere would be impacted if there were no hydrosphere.

Answers

Answer:

Without the hydrosphere, the atmosphere will no longer be able to carry up the evaporated water, as well as pour down the water, leaving the biosphere to rot away. The hydrosphere works with the Biosphere to provide the requirement of water to the organisms needs, as well as the hydrosphere assisting in photosnythesis.

Explanation:

Answer:

The hydrosphere refers to the water on the earth crust. If there were no hydrosphere, we would not have lakes, oceans, rivers, or even a hose full of water. There would also be no life. Nothing can live without water, so nothing would have evolved.

Gaseous chlorine dioxide (ClO2) is used in bleaching flour and municipal water treatment in
500.0L containers. If these processes are performed at room temperature (22.0°C) using 52.1
moles of gas, what is the pressure? Must show calculation setup.

Answers

Taking into account the ideal gas law, the pressure is 2.52 atm.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas are related by a simple formula called the ideal gas law. This equation relates the three variables if the amount of substance, number of moles n, remains constant. The universal constant of ideal gases R has the same value for all gaseous substances. The numerical value of R will depend on the units in which the other properties are worked.

P×V = n×R×T

In this case, you know:

P=?V= 500 Ln= 52.1 molesR= 0.082[tex]\frac{atmL}{molK}[/tex]T= 22 C= 295 K (being 0 C=273 K)

Replacing in the ideal gas law:

P×500 L = 52.1 moles ×0.082 [tex]\frac{atmL}{molK}[/tex] ×295 K

Solving:

P= (52.1 moles ×0.082 [tex]\frac{atmL}{molK}[/tex] ×295 K)÷ 500 L

P= 2.52 atm

Finally, the pressure is 2.52 atm.

Use the heat equation to find out how many joules of energy are needed
to raise the temperature of 67 grams of water form 20°C - 45°C. What is the
answer in kilojoules?
(specific heat of water is 4.2 J/gºC.)

Answers

Answer:

About 7.0 × 10³ J or 7.0 kJ

Explanation:

We want to determine the amount of energy needed to raise the temperature of 67 grams of water from 20°C to 45°C.

We can use the heat equation:

[tex]\displaystyle q = mC\Delta T[/tex]

Where C is the specific heat of water.

Substitute and evaluate:

[tex]\displaystyle \begin{aligned} q & = (67\text{ g})\left(\frac{4.2\text{ J}}{\text{g-$^\circ$C}}\right)\left(45^\circ \text{ C}- 20.^\circ\text{ C}\right) \\ \\ & = (67\text{ g})\left(\frac{4.2\text{ J}}{\text{g-$^\circ$C}}\right)(25^\circ \text{ C}) \\ \\ & = 7.0\times 10^3 \text{ J}\end{aligned}[/tex]

Recall that there are 1000 J in a kJ. Hence:

[tex]\displaystyle \begin{aligned} q & = 7.0\times 10^3 \text{ J} \cdot \frac{1\text{ kJ}}{1000\text{ J}} \\ \\ & = 7.0 \text{ kJ}\end{aligned}[/tex]

In conclusion, it will take about 7.0 × 10³ J or 7.0 kJ of energy to raise the temperature of 67 grams of water from 20 °C to 45 °C.

c) It has a lower boiling point than water, and it likely has weaker electrostatic forces between its molecules than water.
D) It has a lower boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.

Answers

Answer:

It has a higher boiling point than water, and it likely has a stronger electrostatic forces between its molecules than water.

Explanation:

The unknown substance has a higher boiling point than water, and it likely has stronger electrostatic forces between its molecules than water.

What is the meaning of Boiling Point ?

The temperature at which a liquid's saturated vapour pressure equals the air pressure surrounding it is known as the boiling point.

It is given that an unknown substance has a boiling point of 174°C.

The boiling point of water is 100°C.

So the boiling point of the unknown substance is higher than that of water.

Higher boiling point signifies more heat required to break the bonds.

Higher boiling point means existence of strong non covalent bonds.

This means  it likely has stronger electrostatic forces between its molecules than water.

Therefore Option A is the correct answer.

given the reaction 4Na(s) +O2 -> 2Na2O How many grams of Na2O can form from 3.0g of Na? use these molecular weight Na=23g/mole and O = 16g / mole​

No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol

Mr of Na2O = 23+23+16 = 62 g/mol

n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol

m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g

A mixture of 0.384 M H2O, 0.384 M Cl2O, and 0.652 M HClO are placed in a vessel at 25 oC. Calculate the equilibrium concentration (in molarity) of HClO at the same temperature.

Answers

Equilibrium concentration of HOCl at 25°C is 0.140 M

The equation of the reaction at equilibrium is given below:

H₂O (g) + Cl₂O (g) ⇄ 2 HOCl (g)

Equilibrium constant, Kc = 0.0900 at 25°C

An ICE chart for the reaction is set up below

     H₂O (g)  +  Cl₂O (g)   ⇄  2 HOCl (g)

I     0.384        0.384             0.652

C     -x                -x                   + 2x

E    0.384 - x   0.384 - x       0.652 + 2x

The equation of the equilibrium constant is given as;

Kc = [tex]\frac{[HOCl]^2}{[H_{2}O][Cl_{2}O]}[/tex]

substituting the values into the equation:

Kc = [tex]\frac{(0.652 + 2x)^2}{( 0.384 - x)( 0.384 - x)}[/tex] = 0.0900

4x² + 2.608x + 0.425 = 0.0900 (0.147 - 0.768x + x²)

4x² - 0.09x² + 2.677x - 0.069x + 0.425 - 0.013 = 0

3.910x² + 2.677x + 0.412 = 0

Solving using the quadratic formula:

a = 3.910, b = 2.677, c = 0.412

x = [tex]\frac{-2.677\±\sqrt{2.677^2 - 4*3.910*0.412}}{2*3.910}[/tex]

x = -0.256 or -0.431

The negative sign indicates that equilibrium is to the left of the reaction

Since x cannot be greater than 0.384, x = -0.256.

Equilibrium concentration of HOCl = 0.652 + 2(-0.256)

Equilibrium concentration of HOCl at 25°C is 0.140 M
