Shtirlitz [24]

Answer:

The answer is "\bold{HClO_3 > HClO_2 >HClO > HBrO}"

Explanation:

We arrange oxoacids to decrease the intensity of acids in this question. Or we may conclude all this from strongest to weakest acids they order oxoacids, that's why above given order is correct.

HELP!!!
kondaur [170]

Answer: Geothermal resources are reservoirs of hot water that exist at varying temperatures and depths below the Earth's surface. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including electricity generation, direct use, and heating and cooling. In the United States, most geothermal reservoirs are located in the western states.

Renewable—Through proper reservoir management, the rate of energy extraction can be balanced with a reservoir's natural heat recharge rate.

Baseload—Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions.

Domestic—U.S. geothermal resources can be harnessed for power production without importing fuel.

Part 1. A lightly inflated balloon is placed in a freezer. Explain the change to the size of the balloon based on the kinetic mo
Eduardwww [97]

According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.

<h3>What is Kinetic molecular theory ?</h3>

Kinetic molecular theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules.

According to this theory, gas pressure arises due to particles colliding with each other and the walls of the container.

Because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.

This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

Due to the sun's heat, the kinetic energy of particles in the balloon increases and it expands and continues to expand and comes to a stage when the balloon bursts.

Therefore,

According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.

Calculate the volume in milliliters of a 2.09 M silver nitrate solution that contains 400 g of silver nitrate AgNO3. Round your
Liula [17]

<u>Answer:</u> The volume of solution is 1.13 L

<u>Explanation:</u>

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

We are given:

Molarity of solution = 2.09 M

Given mass of silver nitrate = 400. g

Molar mass of silver nitrate = 170 g/mol

Putting values in above equation, we get:

2.09M=\frac{400}{170\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{400}{170\times 2.09}=1.13L

Hence, the volume of solution is 1.13 L
