3.00 g
5.56 g
8.40 g
Answer : The amount left of leutium-176 will be, 2.10 g
Solution :
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the amount left of the sample.
Expression for rate law for first order kinetics is given by :
where,
k = rate constant =
t = decay time =
a = initial amount of the sample = 16.8 g
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the amount left of leutium-176 will be, 2.10 g
Answer:
A.
Explanation:
Answer:
The theoretical yield of copper is 79.6281 g
Explanation:
Moles of copper sulfate =
According to reaction 1 mol of copper sulfate gives 1 mol of copper .
Then 1.2530 mol of copper sulfate will gives :
of copper .
Mass of 1.2530 mol of copper :
1.2530 mol × 63.55 g/mol = 79.6281 g
The theoretical yield of copper is 79.6281 g
Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. .
