Answer:

160 gm

Explanation:

Five times as much water means you can dissolve 5 times as much potassium nitrate    5 x 32 = 160 gm  <u> <===== this seems unlikely though as I doubt 32 g  of  potassium nitrate will dissolve in only  1 cm^3 of water 1 cm^3 of water is only 1 gm of water </u>

C + 2H2 -&gt; CH4
ankoles [38]

Answer:

<u>C) 4</u>

Explanation:

<u>The reaction</u> :

  • C (s) + 2H₂ (g) ⇒ CH₄ (g)

       12g      4g             16g

Hence, based on this we can say that : <u>2 moles of hydrogen gas are needed to produce 16g of methane.</u>

<u />

<u>For 32g of methane</u>

  • Number of moles of H₂ = 32/16 × 2
  • Number of moles of H₂ = <u>4</u>
