When aluminum is placed in concentrated hydrochloric acid, hydrogen gas is produced. 2 al ( s ) + 6 hcl ( aq ) ⟶ 2 alcl 3 ( aq ) + 3 h 2 ( g ) what volume of h 2 ( g ) is produced when 3.60 g al ( s ) reacts at stp?

The volume of hydrogen gas produced at STP is 4.90 liters.

Explanation:

Moles of aluminium =

According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.

Then 0.1333 moles of aluminium will give:

of hydrogen gas

Volume of 0.2 moles of hydrogen gas at STP = V

Temperature at STP = T = 298.15 K

Pressure at STP = P = 1 atm

n = 0.2 mol

PV = nRT (Ideal gas equation)

The volume of hydrogen gas produced at STP is 4.90 liters.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
