Answer: x=41

Sin, cos and tan are part of the trigonometric function. Sin is calculated from opposite/hypotenuse, while cos is calculated from adjacent/hypotenuse.
There is some formula that can be derived from the equation. One of them is sin (90-x)= cos x
If you use it, the calculation would be:
<span>sin 49° = cos x
</span><span>sin 49= sin (90-x)
49= 90-x
x= 90-49= 41</span>

How many grams of water are produced when 35.8 grams of Calcium hydroxide reacts with lots of Hydrochloric acid?

Veseljchak [2.6K]

Are produced 72 grams of water in this reaction.

<h3>Mole calculation</h3>

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

$Ca(OH)_2 + 2HCl = > 2H_2O + CaCl_2$

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:2, so we can perform the following expression:

$MM_{Ca(OH)_2} = 74.1g/mol$

$MM = \frac{g}{mol}$

$74.1 = \frac{35.8}{mol}\\mol = 2$

So, if there are 2 mols of Ca(OH)2:

Ca(OH)2 | H2O

$\frac{1mol}{2mol} =\frac{2mol}{xmol}$

$x = 4mol$

Finally, just find the number of grams of water using your molar mass:

$MM_{H_2O} = 18g/mol$

$18= \frac{m}{4}\\m = 72g$

So, 72 grams are produced of water in this reaction.
