Answer:

The answer to your question is: C. A gas turning into plasma.

Explanation:

The plasma state is similar to the gas state, but these to states behave very different.

Like gases, plasma does not have a shape or fixed volume and are less denser than solids and liquids.

But, unlike gases, plasma are made up of atoms in which some of the electrons have been stripped away.

Answer:

If enough heat is added to a substance, electrons begin to separate from the atomic nuclei.  This describes the process where a gas that becomes plasma (option C)

Explanation:

Plasma is a state of matter that is characterized by its high energy and instability. It is a gas-like state, composed of ionized atoms in which electrons circulate freely. In other words, the molecules are ionized, that is, they have detached themselves from some of their electrons, thus forming a mixture of positive nuclei and free electrons, which has the ability to conduct electricity. The plasma has no definite shape or defined volume.

Plasmas are good conductors of electricity.

Plasma is formed under extremely high temperatures and pressures, making the impacts between electrons very violent, separating from the nucleus and leaving only scattered atoms. In other words, plasma is produced when a gas is heated at very high temperatures causing collisions between the atoms that release electrons by ionizing the gas.

Finally, <u><em>if enough heat is added to a substance, electrons begin to separate from the atomic nuclei.  This describes the process where a gas that becomes plasma (option C)</em></u>

How many milligrams of MgI2 must be added to 257.7 mL of 0.087 M KI to produce a solution with [I−] = 0.1000 M?
lbvjy [14]

Answer:

The answer is 465.6 mg of MgI₂ to be added.

Explanation:

We find the mole of ion I⁻ in the final solution

C = n/V -> n = C x V = 0.2577 (L) x 0.1 (mol/L) = 0.02577 mol

But in the initial solution, there was 0.087 M KI, which can be converted into mole same as above calculation, equal to 0.02242 mol.

So we need to add an addition amount of 0.02577 - 0.02242 = 0.00335 mol of I⁻. But each molecule of MgI₂ yields two ions of I⁻, so we need to divide 0.00335 by 2 to find the mole of MgI₂, which then is 0.001675 mol.

Hence, the weight of MgI₂ must be added is

Weight of MgI₂ = 0.001675 mol x 278 g/mol = 0.4656 g = 465.6 mg

When Z-4,5-dimethyloct-4-ene is treated with hydrogen chloride, HCl, the result is:________.
Vika [28.1K]

Answer:

The  correct option is  c

Explanation:

The chemical equation for the reaction of  Z-4,5-dimethyloct-4-ene and HCl is shown on the first uploaded image

Now looking at the product we see that there are two who has four different groups attached to them this carbon are known as chiral carbons hence the product formed is a pair of diastereomers

One hour of bicycle riding can require 500-900 kcal of energy, depending on the speed, the terrain, and the weight of the racer.
solniwko [45]

Answer:

145 hours

Explanation:

Since one hour of riding a bicycle takes up 505 kcal of energy. It is also stated that one gram of body fat is equal to 7.70 kcal. Also, it is given that 1 pound of body fat is equal to 454 g.

Hence;

1 Ib= 454 g

21 Ib= 21 × 454/1 = 9534 g

But

1g of body fat = 7.70kcal

9534 g of body fat = 9534 × 7.70 kcal/1 = 73411.8 kcal

If 505 kcal is lost in 1 hour

73411.8 kcal is lost in 73411.8 kcal × 1hour/505k cal = 145 hours
