Answer:

its A reduces stress :)))

Explanation:

According to Le Chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress.

Le Chatelier’s principle states that when a chemical equilibrium become imbalance by any change such as change in concentration, temperature, pressure etc. the system will reduces this stress by creating a new equilibrium  state.

By this principle, when temperature increases for an endothermic system, forward reaction will takes place more since the temperature is absorbed there.

Similarly, when the concentration of any reactant increases, the reaction will turn to that direction in  which that reactant is consumed more. If any loss the volume, then the equilibrium will shifts to that direction in which the that substance is produced.

Hence, the system will somehow manage the imbalance by reducing the stress occurred.

Answer:

Osmosis

Explanation:

Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.

Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.

Answer:

The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.

Explanation: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

Answer:

Explanation:

The really interesting characteristic of the atmosphere is that each layer has a different temperature range. That is truly incredible when you list them.

The first layer is the troposphere. It is the layer closest to the earth's surface. It is 12 km high and goes from 15oC to - 56oC

The next layer is the Stratosphere. It is 38 km above the  Troposphere and the temperature goes from -56 to -2.5

The third layer is Mesosphere. It is 40 km above the Stratosphere and the temperature goes from -2.5 to -86.5

The next layer is the Thermosphere.  It is 710 km above the Mesosphere. It goes from - 86.5 to 1200o C So this goes from - 100 roughly to + 1200. That is a massive distance. It speaks wonders of how balanced this planet really is.

The final layer is the Exosphere. It goes up to 3000 km. The temperature is consistently at 1200oC

What I don't understand is how you get the layers from a 13 answer of something. What is the first name of the particle? That would seem to have nothing to do with this answer. Please explain because this was a good deal of work that might be for nothing. Mind you the answer is very interesting.

Explanation:

The process of electroplating an iron key with silver involves electrolysis.

The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.

Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.

The silver anode is therefore depleted in mass while the iron key increases in mass.

Answer:

CNH5 i guess...................

Answer:

CNH5 is the formula.

Explanation:

There is 1 carbon molecule, 1 nitrogen molecule, and 5 hydrogen molecule.

Answer:

This molecule is AgN3

Explanation:

Answer:

AgN3

Explanation:

Mass of nitrogen N is given as 24.36 g

Molar mass of nitrogen N= 14 g/mol.

amount of substance in mol of N = mass/molar mass

=24.36 g/ 14 g/mol.

=1.74 mol.

Given mass of silver= 62,64 g.

Molar mass of silver Ag=107.87 g/mol

Number of mols=62.64 g ÷ 107.87 g/mol.

=0.58 mol.

Ratio of number of mol of N and number of mols of Ag = 1.74 mol / 0.58 mol

=3:1

Hence, empirical formula is AgN₃.

Answer:

12 protons and 12 neutrons are present in Mg and

38 protons and 50 neutrons are present in Sr

Explanation:

Answer:

For ²⁴Mg

1. Proton number = 12

2. Neutron number = 12

For ⁸⁸Sr:

1. Proton number = 38

2. Neutron number = 50

Explanation:

For ²⁴Mg:

1. Determination of the number of proton.

The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.

Atomic number = 12

Proton number = Atomic number

Proton number = 12

2. Determination of the Neutron number.

Mass number = 24

Proton number = 12

Neutron number =?

Mass number = Proton + Neutron

24 = 12 + Neutron

Collect like terms

Neutron = 24 – 12

Neutron number = 12

For ⁸⁸Sr:

1. Determination of the number of proton.

The atomic number of ⁸⁸Sr is 38.

Atomic number = 38

Proton number = Atomic number

Proton number = 38

2. Determination of the Neutron number.

Mass number = 88

Proton number = 38

Neutron number =?

Mass number = Proton + Neutron

88 = 38 + Neutron

Collect like terms

Neutron = 88 – 38

Neutron number = 50
