a. one carbon and one oxygen?

Answer:

(1) Carbon + (1) Oxygen = Carbon monoxide (CO)

Explanation:

Carbon monoxide (CO), an odorless, colorless gas, which can cause sudden illness and death, is produced any time a fossil fuel is burned.

b. one carbon and two oxygen?

Answer:

(1) Carbon + (2) Oxygen = Carbon dioxide (CO2)

Explanation:

a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.

c. one carbon and four chlorine?

Answer:

(1) Carbon + (4) Chlorine = Carbon tetrachloride (CCl4)

Explanation:

Carbon Tetrachloride is a clear, colorless, volatile and very stable chlorinated hydrocarbon. Carbon Tetrachloride is used as a solvent for oils and fats, as a refrigerant and as a dry-cleaning agent. Inhalation of its vapors can depress central nervous system activity and cause degeneration of the liver and kidneys. Carbon Tetrachloride is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in experimental animals.

What percent of physically assaulted or abused adolescents reported lifetime substance abuse or dependence? Select one:

d. 25 percent

Explanation:

The study performed at the National Institute of Justice in 2003, called "Youth Victimization: Prevalence and Implications", Washington, D.C., U.S. Department of Justice, showed a rate of lifetime substance abuse or dependence at approximately 25 percent for adolescents who had been physically assaulted or abused. This compares to a rate of approximately six percent for adolescents who had not been physically assaulted or abused.

How many electrons would found in the ion who’s symbol is I-?

inna [77]

Answer:

54 electrons

Explanation:

I(iodine) has 7 electrons on the last level, so it can take 1 more electrons.

I- also shows that 1 additional electron was added. (I^-1)

I (iodine) has 53 electrons.

So, I- will have 54 electrons.

sa solution is made by dissolving 26.42 g of (NH4)2SO4 in enough H2O to make 50.00 mL of solution. what is the molarity of the s

krok68 [10]

The answer is 0.2 M.

Molarity is a measure of the concentration of solute in a solution

c = n ÷V
c - concentration of solute,
n - number of moles of solute
V - volume of solution

We know:

V = 50.00 mL = 0.05 L

c = ?

n = ?

Let's calculate concentration:

c = m/(V * Mr)

The molar mass of (NH4)2SO4 is the sum of atomic masses (Ar) of its elements):
Mr ((NH4)2SO4) = 2Ar(N) + 8 Ar(H) + Ar(S) + 4Ar(O)
= 2 * 14 + 8 * 1 + 32 + 4 * 16 =
= 28 + 8 + 32 + 64 =
= 132 g/mol

c = 26.42 g/ (0.05 L * 132g /mol) =26.42 g/ 6.6 L*g/mol = 4 mol/L = 4 M

Now, calculate molarity:
c = n ÷V
n = c * V
n = 4 mol/L * 0.05 L
n = 0.2 mol
