Answer:

2.5 x 13.7 = 34.25

4.9 + 1.6 = 6.5

Step-by-step explanation:

Here we are multiplying 2 decimals we can just write it as

25 * 10^{-1} * 137 * 10^{-1}

= 25*137*10^{-2}

= 3425 *10^{-2}

= 34.25

Here we are just performing simple addition

4.9 + 1.6

= 49 *10^{-1} +16*10^{-1}

= (49+16)*10^{-1}

=65 * 10^{-1}

= 6.5

Pls help i forgot how to do this<br>Find the area of the parallelogram.​
nydimaria [60]

Answer:

<h2><u><em>3484 </em></u>ft^{2}</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 ft^{2}

<u><em>Hence,</em></u>

<u><em>The required area of the parallelogram is 3484 </em></u>ft^{2} <u><em>(Ans)</em></u>

How much Zn and how much HCl should be used to produce 1.5 g ZnCl2
tatuchka [14]

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.
