There are 1000 mL in a L.

12.5 L = 12.5(1000) mL = 12500 mL

12500 mL = 12.5 L

Hope this helps!

12500 mL = 12.5 L would be correct

A decrease in the magnitude of velocity is called

IceJOKER [234]

<span>The answer is deceleration. Acceleration is the general term to refer to the change in velocity. Acceleration = change in velocity / change in time. When you want to highlight the fact that the change in velocity is a decrease in the magnitude, you can use the term deceleration, which means that the acceleration is negative.</span>

A radioactive isotope of potassium (k) has a half-life of 20 minutes. if a 43 gram sample of this isotope is allowed to decay fo

Ksenya-84 [330]

Hello!

The half-life is the time of half-disintegration, it is the time in which half of the atoms of an isotope disintegrate.

We have the following data:

mo (initial mass) = 43 g

m (final mass after time T) = ? (in g)

x (number of periods elapsed) = ?

P (Half-life) = 20 minutes

T (Elapsed time for sample reduction) = 80 minutes

Let's find the number of periods elapsed (x), let us see:

$T = x*P$

$80 = x*20$

$80 = 20\:x$

$20\:x = 80$

$x = \dfrac{80}{20}$

$\boxed{x = 4}$

Now, let's find the final mass (m) of this isotope after the elapsed time, let's see:

$m = \dfrac{m_o}{2^x}$

$m = \dfrac{43}{2^{4}}$

$m = \dfrac{43}{16}$

$\boxed{\boxed{m = 2.6875\:g}}\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)

inn [45]

Answer:

Correct option -D

Explanation:

Here, A kinetics experiment is set up is set up to collect the gas that is generated from the cacarbonate and methanoic acid.

Among the given conditions, decreasing the particle size of calcium carbonate only increases the production of gas.

Smaller particles of reactant increases the surface area then followed by rate of reaction will be increases it leads to increases the production of gas.

Therefore, the suitable experimental condition most likely to increase the gas production is-

Decreasing the particle size of the $CaCO_{3}$ by grinding it into a fine powder.

Hence, correct option -D.
