using decay rates.
Answer:
its d and can i get brainliest plz:)
Explanation:
The statement accurately describes radioactive dating Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
What is radioactive substance?A substance in which a unstable nuclei is contained is called as radioactive substance. Radioactive decay is a process in which an unstable nucleus loses energy by the process of radiation. There is a random process that happens in radioactive substances that is radioactivity. The type of product produced after radioactive emission depends on the type of radioactive decay.
Radioactive decay can be of different types like alpha decay, gamma decay or beta decay. Alpha particles, beta particles or gamma particle are emitted in these.
Given options are-
Geologists use only one type of radioactive dating.
Geologists compare parent and daughter elements to determine rock type.
Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Therefore, The statement accurately describes radioactive dating Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.

Why must the final product of a decay series be stable?
a. The daughter isotope of any radioactive decay is stable.
b. No decay chain can emit more than two particles.
c. Each decay results in a net loss of particles.
d. If the daughter isotope is unstable, it will decay.
Answer:
I think its d
Explanation:
Because isotopes decay due to being unstable so if the daughter isotope is unstable it will just decay till it produces a stable isotope
Answer:
d. If the daughter isotope is unstable, it will decay

According to the cup wall diagrams, why does the double wall vacuum
sealed cup outperform the other two cups
Because the particles are moving so fast in a vacuum that
they are able to pass through the walls and transfer more
kinetic energy to the liquid in the cup.
B
The vacuum allows for the all of the particles to pack in tightly
therefore nothing can pass through.
There is little to no transfer of kinetic energy between the
walls of the cups because there are no particles in a vacuum.
And since there is little to no transfer of kinetic energy there
is little to no transfer of temperature. Therefore the liquid
inside stays warmer/colder longer.
The particles in a vacuum do not move at all. Therefore there
is no kinetic energy and nothing can be transferred.

What will happen to the gas molecules in the container as thermal energy is applied?
a-The movement, kinetic energy, and pressure of the molecules will increase.
b-The movement, kinetic energy, and pressure of the molecules will decrease.
c-The movement, kinetic energy, and pressure of the molecules will stay the same.
d-The movement of the molecules will increase, but the kinetic energy and pressure of the molecules will stay the same.
PLZ HELP I HAVE A BENCHMARK TEST!!!!
Decreased because we all know what happen if we put it with thermal energy
When thermal energy is supplied to gas molecules in the container, the movement, kinetic energy, and pressure of the molecules will increase.
Gas molecules are in constant random motion. They collide frequently which other and the walls of the container.
When thermal energy is applied, the gases move faster (acquire higher velocity). The kinetic energy also increases accordingly.
As a result of the increase in thermal energy, gas molecules collide with the walls of the container more frequently (pressure increases).

Explanation:
Since the sun is tilted on it's axis, then the rays of the sun fall on the equator, directly, and that causes it to heat the equator more than the other regions.
Sometimes the sun's rays are on two tropics, Cancer and Capricorn, and that causes the Earth to heat unevenly, which causes wind and ocean currents to form.

Based on the reaction shown above, what volume of 0.246 M
HCl is needed to titrate a 200 mL of 0.048 M Al(OH)3 solution?
mL
Answer:
117.07 ml
Explanation:
Right on ck-12
The volume of 0.246 M HCl needed to titrate 200 mL of 0.048 M Al(OH)₃ solution is 117 mL
Balanced equation3HCl + Al(OH)₃ —> AlCl₃ + 3H₂O
From the balanced equation above,
The mole ratio of the acid, HCl (nA) = 3The mole ratio of the base, Al(OH)₃ (nB) = 1How to determine the volume of HCl Molarity of acid, HCl (Ma) = 0.246 MMolarity of base, Al(OH)₃ (Mb) = 0.048 MVolume of base, Al(OH)₃ (Vb) = 200 mLVolume of acid, HCl (Va) =?MaVa / MbVb = nA / nB
(0.246 × Va) / (0.048 × 200) = 3
(0.246 × Va) / 9.6 = 3
Cross multiply
0.246 × Va = 9.6 × 3
Divide both side by 0.246
Va = (9.6 × 3) / 0.246
Va = 117 mL
