The balanced equation is
<span>Zn + 2 AgNO3 = Zn(NO3)2 + 2 Ag </span>
<span>the ratio between Zn and AgNO3 is 1 : 2 </span>
<span>moles AgNO3 required = 5.7 x 2 =11.4 </span>
<span>we have only 8.9 moles of AgNO3 so it is the limiting reactant </span>
<span>moles Zn needed = 8.9/2=4.45 </span>
<span>moles Zn in excess = 5.7 - 4.45 =1.25 ( or 1.3 at two significant figures)

Answer:
V ≅ 523.33
Step-by-step explanation:
V = 4/3(π*r³)
here r is 5 then
= 4/3 (π*5³)
≅ 523.33

Answer:
The simplified expressions are
1) a - b + c + m + n
2) x + a + m - 2
3) m + a - k - b
4) x + a - b - c + d
Step-by-step explanation:
1) a - (b - c) + (m + n)
To simplify the above expression, we have;
a - (b - c) + (m + n) = a - b - (-c) + m + n = a - b + c + m + n
2) x + a + (m - 2)
To simplify the above expression, we have;
x + a + (m - 2) = x + a + m - 2
3) m + (a - k - b)
To simplify the above expression, we have;
m + (a - k - b) = m + a - k - b
4) x + (a - b) - (c - d) = x + a - b - c -(- d)) = x + a - b - c + d
