what are the affects of increasing thermal energy B

Answers

Answer:

The molecules tend to speed up and move faster throughout the substance once thermal energy increases. This is evident whenever we heat up water as its molecules tend to move faster throughout the water as thermal energy tends to increase

what is nucular decay

Answers

nuclear decay is the decay of atoms on the atomic scale. “Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.”

Answer:

Nuclear decay is also called radioactive decay, and it occurs in a series of sequential reactions until a stable nucleus is reached. Nuclear reactions release much more energy—orders of magnitude more—than exothermic chemical reactions.

If I have 38g of MgCl2, how many moles do I have?

Answers

Answer:

0.3991

Explanation:

no. of moles = mass/molar mass.

so lets get the molar mass of MgCl2

(Mg=24.305 and Cl=35.453) so the molar mass of MgCl2= 24.305+(2*35.453)

molar mass of MgCl2= 95.211

now lets get the no of moles:

no of moles=38g/95.211=0.3991

How are the atoms of carbon different from the atoms of nitrogen

Answers

Answer:

Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.

Explanation:

As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!

UGRENT! Please help showing all work

Answers

Answer:

a. Oxygen

b. 20.39g of Al₂O₃

c. 87%

Explanation:

In order to produce 2moles of Al₂O₃, we need to make react 4 moles of Al, to 3 moles of O₂.

We determine the limiting reactant with the moles of each:

12.98g / 26.98g/mol = 0.481 moles of Al

9.6g / 32g/mol = 0.300 moles of oxygen

4 moles of Al react to 3 moles of O₂

Then, 0.481 mol may react to (0.481 . 3)/4 = 0.361 moles

We only have 0.300 moles of O₂ and we need 0.361. Oxygen is the limiting reactant.

So 3 moles of O₂ can produce 2 moles of Al₂O₃

Our 0.300 moles may produce (0.300 . 2) / 3 = 0.200 mol

Our theoretical yield is: 0.2 mol . 101.96g/ mol = 20.39 g

To determine the percent yield we calculate:

(Produced yield/ Thoeretical yield) . 100 → (17.74 /20.39) . 100 = 87%

Find the mass of 0.456 mol of Ca(OH)2
Please if you can show the work.

Answers

Answer:

Ca(OH)2 molecular weight. Molar mass of Ca(OH)2 = 74.09268 g/mol. This compound is also known as Calcium Hydroxide. Convert grams Ca(OH)2 to moles or moles Ca(OH)2 to grams. Molecular weight calculation: 40.078 + (15.9994 + 1.00794)*2 ››

Answer:

Hey,

QUESTION)

A) Let's first calculate the molar mass M of the molecule :

M(Ca(OH)₂) = M(Ca) + 2M(O) + 2M(H)

M(Ca(OH)₂) = 40 + 2 x 16 + 2 x 1 M(Ca(OH)₂) = 74 g/mol

B) Let's deduct the corresponding mass m :

m = M x n

m = 74 x 0.456 m = 33.744 g m ≈ 34,0 g

The mass of calcium hydroxide corresponding to this quantity of substance (in mol) is therefore 34 g.

B. The outside of a glass of ice water becomes moist.
C. Frost forms on a blade of grass.
D. A cloud forms in the sky,
SUBMIT

Answers

Answer:

A. Perspiration dries on a person's skin.

When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down. Sweat is a great cooling system, but if you're sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.

Pedro colocó en invierno una puerta de madera en la entrada principal de su casa. En abril, temporada donde las temperaturas ambientes son muy altas, notó que la puerta rosaba e incluso dañaba parte del piso de su entrada, considerando el factor de la temperatura, ¿Qué fenómeno físico podría ser la causa de lo sucedido?

Answers

Answer:

imbibición

Explanation:

La propiedad responsable del fenómeno observado es la imbibición de la puerta de madera maciza.

La imbibición se refiere a una situación en la que las partículas sólidas de una sustancia absorben agua sin formar una solución.

A medida que la puerta de madera absorbe agua, se hincha. Esto es responsable del levantamiento de la puerta. Esta absorción de agua ocurre cuando la temperatura y la humedad relativa son altas. Esto es así porque el aire más cálido retiene más humedad.

What is the pH of 0.12M HNO3

Answers

Answer:

pH= 0.92

Explanation:

HNO3-> H^+ +NO3^-

HNO3 is a strong acid, so it fully dissociates

[HNO3] = 0.12M    [H^+] = 0.12M  

pH= -log[H^+]

pH=-log[.12] = 0.92

pH = 0.92
