nataly862011 [7]3 years ago
5 0

Statement 1 is false because heat is the movement of molecules.

Statement 2 is true because matter is composed of elementary particles which are VERY small.

Statement 3 is false because the kinetic energy of a particle determines its heat and it is impossible for a particle to be completely motionless.

Statement 4 is false because neutrons do not have a charge and make up a large portion of all matter.

A chemist needs to know the concentration of some NaOH that is in the laboratory. To find this out, she titrates a 50.0 mL sampl
RoseWind [281]

Answer: 2.4 M

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

M_1 = molarity of Hl solution = 3.5 M

V_1 = volume of HCl solution = 34.3 ml

M_2 = molarity of NaOH solution = ?

V_2 = volume of NaOH solution = 50 ml

n_1 = valency of HCl = 1

n_2 = valency of NaOH = 1

1\times 3.5M\times 34.3=1\times M_2\times 50

M_2=2.4

Therefore, the concentration of NaOH solution is 2.4 M.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

<span> I got (a). The answer was 7.53. But when I try to solve (d), I keep getting the wrong answer. I subtracted the moles of NaOH from the acid and added the moles to the base. Then I did Ka = (x*([NaClO]+x))/([HClO - x) and then I found the pH</span>

What does the term landslide include?
Leno4ka [110]
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.Earthquake shaking and other factors can also induce landslides underwater.
