ANSWER

When
$x = 8$
$y = - 8$

EXPLANATION

The ordered pair in the table were generated with the function,
$y = 8 - 2x$

To find the value that corresponds to
$x = 8$

We substitute 8 in to the given function and simplify.

We obtain,

$y = 8 - 2(8)$

Let us multiply to obtain,

$y = 8 - 16$

We now simplify to get,
$y = - 8$

Therefore when x is 8 the value of y is -8.

Y=8-2×
y=8-2(8)
y=8-16
y=-8

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.
