Answer:

0.004012km

Explanation:

Problem:

Conversion of millimeters(mm) to Kilometers:

value given = 4012mm

Here, we are converting from a submultiple unit to a multiple unit.

Millimeter depicts 10⁻³m and kilometer stands for 10³m

Now, we must find how many exponents will take us from 10⁻³ to  10³

careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:

   i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³

Therefore,

       10⁶mm = 1km

      4,012mm = \frac{4012}{1000000} = 0.004012km

C + 2H2 -> 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>
