How many grams of H2 gas are produced if 48
grams of CH4 gas are consumed?

Mass = 12.12 g

Explanation:

Given data:

Mass of CH₄ = 48 g

Mass of H₂ produced = ?

Solution:

Chemical equation:

CH₄ →   C + 2H₂

Number of moles of CH₄:

Number of moles = mass/molar mass

Number of moles = 48 g/ 16 g/mol

Number of moles = 3 mol

Now we will compare the moles of CH₄  and H₂.

               CH₄          :           H₂

                  1             :           2

                  3            :          2/1×3 = 6 mol

Mass of  H₂:

Mass = number of moles × molar mass

Mass = 6 mol × 2.02 g/mol

Mass = 12.12 g

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
