The difference between GDP and GNP

1 answer:

4 0

GDP measures the value of goods and services produced within a country's borders, by citizens and non-citizens alike. GNP measures the value of goods and services produced by only a country's citizens but both domestically and abroad. GDP is the most commonly used by global economies.

In which instance is a gas most likely to behave as an ideal gas?A.) At low temperatures, because the molecules are always far a

kiruha [24]

Answer:

C.) At room temperature and pressure, because intermolecular interactions are minimized and the particles are relatively far apart.

Explanation:

For gas to behave as an ideal gas there are 2 basic assumptions:

The intermolecular forces (IMF) are neglectable.
The volume of the gas is neglectable in comparison with the volume of the container.

In which instance is a gas most likely to behave as an ideal gas?

A.) At low temperatures, because the molecules are always far apart. FALSE. At low temperatures, molecules are closer and IMF are more appreciable.

B.) When the molecules are highly polar, because IMF are more likely. FALSE. When IMF are stronger the gas does not behave as an ideal gas.

C.) At room temperature and pressure, because intermolecular interactions are minimized and the particles are relatively far apart. TRUE.

D.) At high pressures, because the distance between molecules is likely to be small in relation to the size of the molecules. FALSE. At high pressures, the distance between molecules is small and IMF are strong.

What is the chemical formula and net ionic equations for all three solutions.

timofeeve [1]

Answer:

See answer below

Explanation:

As you are asking for chemical formula and ionic equation, then, I will assume that after the station #4 below, are the solutions you are requiring.

You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.

Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.

1. Solution 2 Potassium Chloride:

In this case we have Potassium on one side, and Chlorine on the other side, the symbol for those are K and Cl. As Potassium have the +1 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Chlorine it will be -1, so, the formula will be:

KCl

And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:

K⁺ + Cl⁻ ------> KCl

2. Solution 1 Copper(II) sulfate:

In this case we have a tertiary salt, The copper's symbol is Cu, and is working with it oxydation state +2. Sulfate is an anion and it's formula is SO₄ and works with oxydation state -2 instead.

The chemical formula and ionic equation will be:

Copper(II) sulfate: CuSO₄

And the net equation:

Copper sulfate: Cu²⁺ + SO₄²⁻ -------> CuSO₄

3. Solution 3 Sodium hydroxide:

In this case, we have a compound that it's usually used in acid base reactions. This is a strong base or hydroxide, and we have the element of Sodium (Na) with the oxydation state +1, is the only one it can have, and for the other side we have the oxydrile anion OH, and together is working with the oxydation state -1. So the chemical formula will be:

NaOH

And the net ionic equation:

Na⁺ + OH⁻ -------> NaOH

Hope this helps

Which fossil fuel has the least amount of carbon dioxide released in the air each year

Natali5045456 [20]

The correct answer is - natural gas.

The natural gas is the fossil fuel that releases the least amount of carbon dioxide in the atmosphere. It actually releases very little to none. The reason for that is that the natural gas is a fossil fuel which has the methane as its main ingredient. Even when used, it is not causing some serious pollution, instead the pollution comes from not well managed infrastructure and movement from one place to another of the natural gas. The biggest problem, pollution wise, comes from the leaking of the natural gas, when methane is released into the atmosphere.

Ann dissolves four tablespoons of salt in a bowl of water. She notices that the water has become salty. Ann then keeps

antoniya [11.8K]

Answer:

2)Both the salt dissolving and the evaporation of water are physical changes.

Explanation:

The two kinds of changes that has occurred are both physical changes.

Dissolution of a solute such as salt in water and evaporation of water from a solution are physical changes.

A physical change is one in which the physical property of matter is altered. Particularly the state and the form.

In many of these cases, the change is easily reversible.

Since this change is reversible in that we were able to collect the salt back, this is a physical change.
