How many moles of chlorine, cl, are there in 8 moles of carbon tetrachloride, ccl4?

Answers

Answer 1

Answer:

Moles are the amount of substance

the break down of CCl₄ is as follows

CCl₄ --> C + 4 Cl

in the compound CCl₄ - 1 mol of CCl₄ contains 4 mol of Cl

so for every 1 mol of CCl₄ there are 4 mol of Cl

then in 8 mol of CCl₄ - there are 4 x 8 = 32 mol of Cl

so 8 mol of CCl₄ contains 32 mol of Cl

answer is 32 mol of Cl

Answer 2

Answer:

$\boxed{{\text{32 moles}}}$ of chlorine are present in 8 moles of ${\text{CC}}{{\text{1}}_{\text{4}}}$ .

Further Explanation:

Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.

In ${\text{CC}}{{\text{l}}_4}$ , both carbon and chlorine are non-metals. Carbon has four valence electrons whereas chlorine has seven valence electrons. Both share two electrons with each other and a single covalent bond is formed between a carbon and a chlorine atom. So carbon forms four single bonds with four chlorine atoms in order to complete its octet and the octet of chlorine is also fulfilled. This bond is formed due to sharing of the electrons and therefore ${\text{CC}}{{\text{l}}_4}$ is a covalent compound. (Refer to the attached image)

${\text{CC}}{{\text{l}}_4}$ is a covalent compound. So 1 mole of ${\text{CC}}{{\text{1}}_{\text{4}}}$ contains 1 mole of carbon and 4 moles of Cl.

Number of moles of Cl in 1 mole of ${\text{CC}}{{\text{l}}_4}$ = 4

So the number of moles of Cl in 8 moles of ${\text{CC}}{{\text{l}}_4}$ is calculated as follows:

$\begin{aligned}{\text{Moles of Cl}}&=\left({8\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}\right)* \left({\frac{{4\;{\text{mol}}\;{\text{Cl}}}}{{1\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}}}\right)\n &=\boxed{32\;{\text{mol}}}\n\end{gathered}$

So 8 moles of ${\mathbf{CC}}{{\mathbf{l}}_{\mathbf{4}}}$ contain 32 moles of Cl.

Answers

During the test trial, the sugar pill given to the control group is called a placebo. Therefore, the correct option is A. Placebo

What is a placebo ?

A placebo is any drug or a treatment with no active substances, for example a sugar pill.

During clinical trials, usually one group takes the actual drug while the other group takes the placebo without being aware of it.

Placebo is an inactive treatment given to a group of people that is made to look like the real drug, but in reality it simply makes the patient believe they're being treated with the drug and that the drug will help them relieve from the symptoms.

By comparing the results from the two groups, this method helps in analyzing the accurate effects of the drug on the patients and helps in proving that it was the drug that actually treated the symptom and that the treatment did not occur by chance or just a mere belief of the patient thinking they will get better because they're being treated.

This approach helps reduce bias and ensures that the trial's results are more accurate and reliable.

So, the sugar pill given to the control group is called a placebo. Therefore, the correct option is A. Placebo

An atom that has 84 protons and 86 neutrons undergoes a reaction. At the end of the reaction, it has 82 protons and 84 neutrons. What happened to the atom?

Answers

During a nuclear reaction, an atom must emit an alpha particle, which consists of 2 protons (positively charged) and 2 neutrons (neutrally charged). Thus, the alpha particle has a charge of +2 (there are no electrons, which are negatively charged, to balance out the two protons). When an atom emits an alpha particle, it will lose this particle, thus losing 2 protons and 2 neutrons as well. Since the atom in the equation goes from 84 protons to 82, and 86 neutrons to 84, it lost 2 protons and 2 neutrons, indicating that it emitted an alpha particle.

C- it emitted an alpha particle in a nuclear reaction (just took the edg test)

How much heat is given off when 8 g of hydrogen reacts in: 2H₂ + O₂ → 2H₂O; ΔH = -115.60 kcala. -57.8 kcal
b. -115.6 kcal
c. -173.4 kcal
d. -231.2 kcal
e. -462.4 kcal

Answers

ΔΗ= -115.6 kJ/mol
H2 has a Mr of 2, so as mol=mass/mr we can work out that there are 4 moles of H reacting

Therefore we multiply -115.6 by 4 = -462.4

An atom of the element zinc has an atomic number of 30 and a mass number of 65. How many protons does an uncharged zinc atom have?30
35
65
95

Answers

Answer : The correct option is, 30 protons

Explanation :

Element = Zinc

Atomic number = 30

Atomic mass number = 65

As we know that the atomic number is equal to the number of electrons and number of protons.

Atomic number = Number of electrons = Number of protons = 30

Number of neutrons = Atomic mass - Number of protons = 65 - 30 = 35

Therefore, the number of protons an uncharged zinc atom have 30 protons.

Answer:

30 protons

Given that the molar mass of CO2 is 44.01 g/mol, how many liters of oxygen is required at STP to produce 88.0 g of CO2 from this reaction?
44.8 L
45.00 L
89.55 L
89.6 L

Answers

Answer:

89.6 L of O₂

Solution:

The balanced chemical equation is as,

CH₄ + 2 O₂ → CO₂ + 2 H₂O

As at STP, one mole of any gas (Ideal gas) occupies exactly 22.4 L of Volume. Therefore, According to equation,

44 g ( 1 mol) CO₂ is produced by = 44.8 L (2 mol) of O₂

So,

88 g CO₂ will be produced by = X L of O₂

Solving for X,

X = (88 g × 44.8 L) ÷ 44 g

X = 89.6 L of O₂

Took a guess and got it right!

D) 89.6 L

OXIDATION IN
Cl2(aq) + 2Brmc003-1.jpg(aq) mc003-2.jpg 2Clmc003-3.jpg(aq) + Br2(aq)

Answers

I think the chemical reaction is:

Cl2(aq) + 2Br-(aq) = 2Cl-(aq) + Br2(aq)

The oxidation in this reaction is the reaction for bromine where the charge goes from -1 to a neutral charge while the reduction reaction is showed by the chlorine from a neutral charge to a -1 charge.
