Question

What mass of hydrogen is produced when 192 g of magnesium is reacted with hydrochloric acid?​

Answer 1

Mg+2HCL-Magnesium Chloride +Hygrogen

`>`

Step-by-step explanation:

N.O of moles=Mass\Molar Mass

192÷24=8

1:1

8×2=16

Answer 2

`\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}`

`\longrightarrow \sf{Mg+2HCI \Longrightarrow MgCl_2+H_2}`

`\longrightarrow \sf{molMg=129gMg * (1molMg)/(24.305gMg=) }`

`\small \sf{\longrightarrow molH_2=7.90molMg * (1molH_2)/(1molMg)= 7.90molH_2 }`

`\small \sf{\longrightarrow massH_2=7.90H_2 * (2.016g)/(1molH_2)= 7.90molH_2= 15.9 \: gH_2}`

`\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}`

`\small\bm{ The \: mass \: of \:H_2 \: produce \: will \: be \: 15.9 }`
`\bm{grams.}`
