explanation:

The number of moles of HCl produces 400.0 mL of 1.5M MgCl₂ is equal to 1.20 moles. Therefore, option (C) is correct.

A mole can be defined as a standard unit that is used to find a huge number of quantities of molecules, atoms, ions, or other particular particles.

The number of entities in one mole was found to be equal to 6.023 × 10²³ which is called Avogadro’s constant.

The chemical equation of magnesium and HCl is:

Mg (s) + 2HCl (aq) →  MgCl₂ (aq)  +  H₂(g)

The volume of the MgCl₂ solution, V = 400 ml = 0.4 L

The concentration of MgCl₂ = 1.5 M

The number of moles of MgCl₂ = 1.5 × 0.4 = 0.6 moles

One mole of MgCl₂ is produced from HCl = 2

0.6 moles of MgCl₂ is produced from HCl = 2 × 0.6 = 1.20 moles

Therefore, 1.20 moles of HCl will be reacted to produce 0.6 moles of MgCl₂.

1.the smallest things that can carry out life proccess

Answer:

The number of protons and neutrons.

Explanation:

Neutrons and Protons can't be removed from nucleus from chemical reactions because they are held together super strong and tight. However, nuclear reactions are strong enough to separate them.

The number of protons and neutrons

Explanation:

Answer:

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them:

Answer:

When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

Answer:

Part 1:
Arrow F represents Cellular Respiration, showing how the tree produces carbon after it has finished the process of Cellular Respiration.

Part 2:
Matter is conserved in this image because it shows the process of Photosynthesis and cellular respiration. These are both examples of The Law of Conservation of Mass. During both of these processes, the mass of the reactants is the same as the mass of the products.

Part 3:
This process shows the carbon cycle by showing how carbon transfers to many different types of matter and back again. It shows the process of cellular respiration, which produces carbon using the products of photosynthesis, which uses the carbon produced by cellular respiration. This shows a cycle because each of them depends on the other.

Answer:

Stannic nitride, Sn3N4

Explanation:

Answer:

The environment can affect an organisms through natural evolution. Example: Spotted moths camouflage with the bark on trees, but black moths do not. So the black moths are eaten and the spotted moths survive. The white moths then pass on their genes to their offspring, so their offspring will also be spotted. Eventually most moths will be spotted. But when the industrial revolution occured, the bark of the trees changed to a darker colour. Therefore the spotted moths were easily seen by predators and were eaten. But the black moths blended in with the bark so they survived. The black moths then passed on their genes to their offspring so most of the moth population had black wings.

Answer:

174 kPa

Explanation:

Given that,

Initial temperature, T₁ = 25° C = 25+273 = 298 K

Final temperature, T₂ = 225°C = 225 + 273 = 498 K

Initial pressure, P₁ = 104 kPa

We need to find the new pressure. The relation between the temperature and pressure is given by :

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

So,

[tex]P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{104\times 498}{298}\\\\P_2=173.79\ kPa[/tex]

or

P₂ = 174 kPa

So, the new pressure is 174 kPa.

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves.

Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). ... Tidal forces are based on the gravitational attractive force.

If the Tides is working then out “ High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides“.
