CH4(g) + H2O(g) ---> CO(g) + 3H2(g)


mass of methane CH4 = 256g

molar mass of methane,CH4 = C + 4 H = 16.04g/mol


<u>moles of CH4 </u>

= mass/Molar mass

= 256/16.04

= 15.96 moles CH4


<u>moles of H2 produced</u>

= 15.96 moles CH4 x  <u>    3 moles H2     </u>

                                           1 mol CH4

=  47.88 moles H2


<u>number of H2 molecules produced here </u>


= 47.88 moles H2 x   <u>6.022 x 10²³ molecules</u>

                                             1 mole

= 288.335 x 10²³ H2 molecules  

=    <u>2.88 x 10²⁵  H2 molecules</u>


<u>2.88 x 10²⁵</u><u>  H2 molecules </u> are produced when 256g of methane reacts with steam.

What are some chemical properties of Gallium?
Natali [406]

Answer:

Gallium is silvery white and soft enough to be cut with a knife. It takes on a bluish tinge because of superficial oxidation. Unusual for its low melting point (about 30 °C [86 °F]), gallium also expands upon solidification and supercools readily, remaining a liquid at temperatures as low as 0 °C (32 °F).

What is the missing word in the word equation below?
ss7ja [257]

Answer:

sodium carbonate

Explanation:

Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. This type of reaction is called a thermal decomposition.

Ductility - a materials ability to stretch, ie if you pull it apart does it stretch to a wire.

density - ratio of volume to mass

conductivity - materials ability to conduct a current.

hopefully with these definitions you can figure out the answer.

2074 Set B Q.No. 1 What mass of nitrogen will be requires
timurjin [86]

140 g of nitrogen (N₂)

Explanation:

We have the following chemical equation:

N₂ + 3 H₂ -- > 2 NH₃

Now, to find the number of moles of ammonia we use the Avogadro's number:

if        1 mole of ammonia contains 6.022 × 10²³ molecules

then   X moles of ammonia contains 6.022 × 10²⁴ molecules

X = (1 × 6.022 × 10²⁴) / 6.022 × 10²³

X = 10 moles of ammonia

Taking in account the chemical reaction we devise the following reasoning:

If        1 mole of nitrogen produces 2 moles of ammonia

then  Y moles of nitrogen produces 10 moles of ammonia

Y = (1 × 10) / 2

Y = 5 moles of nitrogen

number of moles = mass / molecular weight

mass = number of moles × molecular weight

mass of nitrogen (N₂) = 5 × 28 = 140 g
