2HCI + Na, so, - 2NaCl + H, so,
How much H, so, is produced when 40.0g of HCl react?
ОА 107.60
в 36.5 g
с 08.1 g
O D53.8 g

None of the options are correct.

The correct answer is 1.10g

Explanation:

First, we'll begin by balancing the equation given above. This is illustrated below:

2HCl + 2Na —> 2NaCl + H2

Next, let us calculate the mass of HCl that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:

Molar Mass of HCl = 1 + 35.5 = 36.5g/mol

Mass of HCl from the balanced equation = 2 x 36.5 = 73g

Molar Mass of H2 = 2x1 = 2g/mol

Now we can easily find the mass of H2 produced when 40g of HCl reacted as shown below:

From the balanced equation,

73g of HCl produced 2g of H2.

Therefore, 40g of HCl will produce = (40 x 2)/73 = 1.10g of H2.

From the calculations made above,

40g of HCl produced 1.10g of H2

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

explanation:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
