3. If 175 grams of nitrogen reacted with hydrogen to make hydrogen, how much ammonia would be needed?
zmey [24]

Answer:

37.5 g of H₂

Explanation:

N₂ (28g) + 3H₂ (6g) => 2NH₃ (34g)

Every 28g of N₂ needs 6g of H₂

=> Every 7g of N₂ needs 1.5g of H₂

=> 175g of N₂ needs 1.5 x 25 g of H₂

=> 37.5 g of H₂

What is the final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L
sineoko [7]

Answer: The final concentration of a solution is 0.350 M

Explanation:

According to the dilution law,

C_1V_1=C_2V_2

where,

C_1 = concentration of concentrated acid solution = 12.0 M

V_1 = volume of concentrated acid solution = 35.0 ml

C_2 = concentration of diluted acid solution= ?

V_2 = volume of another acid solution= 1.20 L = 1200 ml

( 1L=1000ml)

Putting in the values:

12.0\times 35.0=C_2\times 1200

C_2=0.350M

The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M

Ethanoic acid, CH3COOH, ionizes to form an ethanoate ion (CH3COO-) in aqueous solution. what else does it form? is it a monoprot
barxatty [35]

Ethanoic acid ionizes in aqueous solutions to form two ions which are CH_3COO^- and H^+

<h3>Ionization of ethanoic acid</h3>

Ethanoic acid goes by the chemical formula CH_3COOH.

In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:

CH_3COOH ---- > CH_3COO^- + H^+

A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single H^+
