Answer:
-1/2 is the slope
Step-by-step explanation:
slope = rise over run
-1 rise for every 2 run
Answer:
The number 10/2 = 5 is an integer.
Step-by-step explanation:
An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...
Integer can be positive, negative of zero.
It is a whole number so it is an integer.
- 0.3
It is not an integer as it has a fractional part.
It also has a fractional part, so it is not an integer.
0.4
It also has a fractional part, so it is not an integer.
Answer:
y=-8x-4
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.
Answer:
Her test score would be an 85 because 5x3=15 and then you would subtract 15 from 100 which would be 85
equation would be x=100-(5y)
