Answer:

D. 17

Explanation:

Halogens (group 17) are most likely to form a -1 ion. This is because they want to complete their octet. A prime example of this is sodium chloride. Sodium chloride is an ionic compound. Sodium gives up its valence electron, therefore, recieving a +1 charge, and Chlorine takes it, giving it a -1 charge. Chlorine is also in group 17, halogens.

3. An object weighs 8.22 lbs. What is the mass in grams?

Rainbow [258]

Answer:

The correct answer is 372852.9 g.

Explanation:

First, we must look for the relationship between the masses in grams and pounds.

To get an approximate result, the relationship between pounds and grams found is:

1 lbs = 453.592 g

Now we must use this relationship as a conversion factor in the following way:

8.22 lbs * $\frac{453.592 g}{1 lbs}$ = 372852.9 g

The mass expressed in grams for 8.22 lbs is 372852.9 g.

Have a nice day!

An ethylene gas torch requires 3200L of gas at 3.0 atm. What will be the pressure of the gas if the Ethylene is supplied by a 25

drek231 [11]

Answer:

38.4 atm.

Explanation:

We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

If n and T are constant, and have different values of P and V:

P₁ = 3.0 atm, V₁ = 3200 L,

P₂ = ??? atm, V₂ = 250.0 L.

∴ P₂ = (P₁V₁)/(V₂) = (3.0 atm)(3200 L)/(250.0 L) = 38.4 atm.
