There are moles of carbon in 6.64 moles of CCl2F2

Answers

Answer 1

Answer:

Answer:

6.64 moles of carbon.

Explanation:

Given data:

Number of moles of C = ?

Number of moles of CCl₂F₂ = 6.64 mol

Solution:

In one mole ofCCl₂F₂ there is one mole of carbon two moles of chlorine and two moles of fluorine are present.

In 6.6 moles of CCl₂F₂ :

Moles of carbon = 6.64 × 1 = 6.64 moles of carbon.

Moles of chlorine = 6.64× 2 = 13.28 moles of chlorine

Moles of fluorine = 6.64× 2 = 13.28 moles of fluorine

Answer 2

Answer:

Answer: 6.64 moles

Explanation:

Number of moles of C = ?

number of moles of CCl₂F₂ = 6.64 mol

In one mole of CCl₂F₂ there is one mole of carbon two moles of chlorine and two moles of fluorine are present.

In 6.6 moles of CCl₂F₂ :

Moles of carbon = 6.64 × 1 = 6.64 moles of carbon.

Moles of chlorine = 6.64× 2 = 13.28 moles of chlorine

Moles of fluorine = 6.64× 2 = 13.28 moles of fluorine

How many atoms are in 3.50 moles of calcium (Ca)?

Answers

$1\ mole\ --\ 6.02*10^(23)atoms\n 3.5\ moles--x\n x=21.07*10^(23)\ atoms$

No. of atoms = no.of moles x avagadro's constant

= 3.50 x 6.022*10^23

= 21.077 x 10 ^23

Calculate the energy in joules and calories required to heat 25.0 g of water from 12.5C to 25.7C

Answers

the heat (Q) required to raise the temp of a substance is:Q=m∗Cp∗ΔT where m is the mass of the object (25.0g in this case), Cp is the specific heat capacity of the substance (for water Cp = 1.00cal/gC, or 4.18J/gC,
and Dt is the change in temp.
You'll have to solve this twice, once with the Cp in calories, and once with the Cp in joules.
1380.72 Joules

What types of epithelial cells would you expect to find in an area of the body where diffusion of nutrients needs to occur?1) Cuboidal
2) Columnar
3) Squamous

Answers

The type of epithelial cells that would be found in an area of the body where diffusion of nutrients needs to occur is squamous.

Epithelial cells refer to the cells that are vital in the lining of the surface of the body. Epithelial cells can be found on the blood vessels, skin, and urinary tract.

It should be noted that epithelial cells are important as they act as a protective barrier and help in stopping viruses from getting inside the human body.

It should be noted that squamous can be found in an area of the body where diffusion of nutrients needs to occur. They're flat cells and they are usually thin and resembles the scale of fishes.

In conclusion, squamous can be found on the surface of the skin.

The nucleus of a radium-226 atom is unstable, which causes the nucleus to spontaneously(1) absorb electrons (3) decay
(2) absorb protons (4) oxidize

Answers

Answer: The nucleus of radium-226 is unstable and hence undergoes decay.

Explanation: Radium has many isotopes. One of them is $_(88)^(226)\textrm{Ra}$ which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.

This isotope undergoes alpha - decay and produces Radon-222 isotope.

Equation for alpha - decay follows:

$_(88)^(226)\textrm{Ra}\rightarrow _(86)^(222)\textrm{Rn}+_2^4\alpha$

Hence, the nucleus of radium-226 undergoes decay process.

The answer is (3) decay. An atom whose nucleus is unstable is said to be "radioactive," and its nucleus undergoes nuclear decay.
