<span>resistance impedes flow of electricity to shorten the voltage of a circuit </span>
Answer:
See explanation
Explanation:
The shorthand nuclear reaction equations have been given; the first particle in the parentheses is a reactant particle while the second particle is a product particle. These can now be rewritten as the longhand equations as follows;
238/92U + 4/2 He -------> 241/94Pu + 1/0 n
238/92U + 4/2 He ------> 241/94Pu + 1/0 n
14/7N + 4/2 He------> 17/8O + 1/1 p
56/26Fe + 2 4/2 He----> 60/29Cu + 4/2 He
Answer:
Q = 2997.69 J
Explanation:
Given that,
The mass of ice, m = 15.6 grams
The temperature increases from -8.76 degrees Celsius to 85.9 degrees Celsius.
The specifc heat of ice is 2.03 J/g°C
We need to find the amount of energy required. The formula for energy required is given by :
So, the required heat is equal to 2997.69 J.
Ozone 03 have 2 sigma bond and 1 pie bond.
just remember this and you can do any problem for pie and sigma with this.
single bond = 1 sigma
double bond = 1 sigma and 1 pie
triple bond = 1 signa and 2 pie
2Al + 3CuCl2 ➡ 2AlCl3 + 3Cu.
Moles of Al = 1.2/27 = 0.045 moles
2 moles of Al reacts with 3 moles of CuCl2.
Therefore, 1 mole of CuCl2 reacts with =2/3 x moles of Al
= 2/3 x 0.045
= 0.03 moles.
