Answer : The rate of consumption of 
is, 
Explanation : Given,
Moles of = 
Volume of solution = 170 mL = 0.170 L (1 L = 1000 mL)
Time = 170 s
First we have to calculate the concentration.
Now we have to calculate the rate of consumption.
Thus, the rate of consumption of is,
Answer:
At-207 (meaning At with the number on the top left being 207 and the number at the bottom left being 85.
Explanation:
The sum of the mass numbers has to equal on both sides, so we need 211 = 4+a
a=207
The sum of the atomic numbers as to equal on both sides, so 87=2+b
b=85
The element is determined by the mass number.
