Step-by-step explanation:
Zn + 2HCl => ZnCl2 + H2
Moles of Zn = 13g / (65.38g/mol) = 0.198mol
Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.
Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.
Answer:
3 is not a function because you cant have the same input with different outputs
4 is a function because each input has one output
Step-by-step explanation:
Answer:
-82, -83, -84
Step-by-step explanation:
Using a variable and corresponding expressions, we can set the sum of the consecutive integers equal to -249 and solve:
first integer: x
second integer: x + 1
third integer: x + 2
x + x + 1 + x + 2 = -249
Combine like terms: 3x + 3 = -249
Subtract 3 from both sides: 3x + 3 - 3 = -249 - 3 or 3x = -252
Divide both sides by 3: 3x/3 = -252/3
Solve for x: x = -84
first integer: -84
second integer: -84 + 1 = -83
third integer: -84 + 2 = -82
We are given volume of a shipping container = 448.656 cubic inches.
And this shipping container can hold = 24 smaller boxes.
Volume of each small box = 
.
= 
On dividing 448.656 by 24 we get
= 18.694.
<h3>Therefore, the volume of each of the smaller boxes is C. 18.694 cubic inches .</h3>
