Answer:
<h2><u><em>3484 </em></u>

</h2>
Step-by-step explanation:
<u><em>Given,</em></u>
<em>The figure is of a parallelogram</em>
Height (h) of the parallelogram = 52 ft.
<u><em>Since,</em></u>
<em>In a parallelogram opposite sides are equal so,</em>
Corresponding base to the height of the parallelogram is = 67 ft.
<u><em>Therefore,</em></u>
Area of the given parallelogram
= base × height
- <em>[On substituting their values]</em>
= 67 ft. × 52 ft.
- <em>[On multiplying]</em>
= 3484
<u><em>Hence,</em></u>
<u><em>The required area of the parallelogram is 3484 </em></u>
<u><em>(Ans)</em></u>
Answer:
If they increase by the same amount each time.
So E.g. 1 3 5 7 9 (+ 2 each time)
BUT NOT e.g. 1 5 6 8 (+ random each time)
Answer:
Step-by-step explanation:
Answer:
- 0.71963 g of Zn
- 0.80256 g of HCl
Step-by-step explanation:
The required mass of reactants can be computed from the number of moles of product.
moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles
Then the mass of Zn required is ...
mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g
Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...
mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g
_____
<em>Comment</em>
The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.
