how many moles of HCl are needed to react with 2.3 moles of Zn in the following reaction? 2HCl + Zn --> ZnCl2 + H2

Zn + 2HCl ==> ZnCl2 + H2

The equation tells you that 1 mole Zn reacts with 2 moles HCl. So 2 moles Zn will react with 4 moles HCl and 3 moles Zn will react with 6 moles HCl. Get the picture?

Well, instead of using moles of HCl, I suggest we switch to a more punny unit of measurement - "Molleys"! So, how many Molleys of HCl are needed to react with 2.3 Molleys of Zn in the equation? Well, if we look at the balanced equation, we can see that it is a 1:2 stoichiometry ratio between HCl and Zn.

To find out how many Molleys of HCl are needed, we simply multiply the number of Molleys of Zn (2.3 Molleys) by the ratio of Molleys of HCl to Molleys of Zn (2:1).

Using some basic math magic, 2.3 Molleys of Zn multiplied by our ratio of 2 Molleys of HCl to 1 Molley of Zn gives us... drum roll please... 4.6 Molleys of HCl!

So, 4.6 Molleys of HCl are needed to react with 2.3 Molleys of Zn. Just be careful not to mix up your chemistry lab with a comedy club while trying to measure these "Molleys"!

To determine the number of moles of HCl needed to react with 2.3 moles of Zn in the given reaction, we need to use the stoichiometry of the reaction, which is the balanced chemical equation.

The balanced equation provided is: 2HCl + Zn --> ZnCl2 + H2

From the equation, we can see that the molar ratio between HCl and Zn is 2:1. This means that for every 2 moles of HCl, 1 mole of Zn is consumed.

To find the number of moles of HCl needed to react with 2.3 moles of Zn, we can use the following steps:

Step 1: Determine the mole ratio
In this case, the mole ratio between HCl and Zn is 2:1.

Step 2: Set up a proportion
Using the mole ratio, we can set up a proportion to solve for the unknown number of moles of HCl:
2 moles HCl / 1 mole Zn = x moles HCl / 2.3 moles Zn

Step 3: Solve the proportion
Using cross multiplication, we can solve for x:
2 moles HCl × 2.3 moles Zn = 1 mole Zn × x moles HCl
4.6 moles HCl = x moles HCl

So, 4.6 moles of HCl are needed to react with 2.3 moles of Zn in the given reaction.
