1, When temperature is increased the volume will also increase. this is because the particles will gain kinetic energy and bombard the walls of the container of the gas at a higher frequency, therefore, for the pressure to remain constant as per Charles' law, the volume will have to increase so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
2. When temperature is Decreased the volume will also Decrease. this is because the particles will loose kinetic energy and bombard the walls of the container of the gas less frequently, therefore, for the pressure to remain constant as per Charles' law, the volume will have to reduce so that the rate of bombardment remains constant. This is explained by the Charles law which states that the volume of a gas is directly proportional to the absolute temperature provided pressure remains constant.
3. When temperature is increased the pressure will increase. This is because the gas particles gain kinetic energy and bombard the walls of the container more frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
4. When temperature is decreased, pressure will decrease, This is because the gas particles lose kinetic energy and bombard the walls of the container less frequently. this is according to Pressure law which states that for a constant volume of a gas the pressure is directly proportional to absolute temperature
5. When particles are added, pressure will increase. This is because the bombardment per unit area also increases. Boyles law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
6. When particles are removed, the pressure will decrease. This is because the bombardment per unit area also decreases. Boyle's law explains this, that at fixed temperature the volume of a gas is inversely proportional to the pressure.
Answer: technetium-99.
Explanation:
This is not an answer that you can look for in a book.
You need to do some research.
You can fiind the abstract of the article titled <span>Molecular imaging of atherosclerosis using a technetium-99m-labeled endothelin derivative.</span>
The conclusion of this scientific article is that labeling with the radiosotope Tc - 99 iis feasibele to visualize the effects of an experiment inducing atherosclerosis, which gives the answer to the question posted.

Answer:
2.18x10^-9 M
Explanation:
From the question given,
Hydrogen ion concentration, [H+] = 4.59x10^-6 M
Hydroxide ion, [OH-] =?
The hydroxide ion concentration, [OH-] in the solution can be obtained as follow:
[H+] x [OH-] = 1x10^-14
4.59x10^-6 x [OH-] = 1x10^-14
Divide both side by 4.59x10^-6
[OH-] = 1x10^-14 / 4.59x10^-6
[OH-] = 2.18x10^-9 M
Answer:
Mass = 32 g
Explanation:
Given data:
Mass of O₂ needed = ?
Mass of NH₃ react = 13.6 g
Solution:
Chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
Number of moles of ammonia:
Number of moles = mass/ molar mass
Number of moles = 13.6 g/ 17 g/mol
Number of moles = 0.8 mol
Now we will compare the moles of ammonia and oxygen from balance chemical equation.
NH₃ : O₂
4 : 5
0.8 : 5/4×0.8 = 1
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 1 mol × 32 g/mol
Mass = 32 g
The answers are 6. A. Igneous
7.To determine past geography is to look at water lines. Many cliffs
contain "stained" waterlines on the surface of the rocks, which shows
that water at a certain level used to occupy that area.
8. B. Deposition
9.C.Metamorphic
10.C.Sedimentary
11.A. Deposition
12.A. Cooling magma or lava
