Answer:
Question 7 the answer is B
Explanation:
In every nuclear reaction there is always formation of products either by nuclei bombardment or by the elements breaking into two elements of the same mass
Question 8
The answer is A
Nuclear reactions release a huge amount of energy than chemical reactions
Answer: Answer:
21.03L
Explanation:
V1 = 456mL = 0.456L
T1 = 23°C = (23 + 273.15)K = 296.15K
P1 = 50atm
V2 = ?
T2 = 273.15K
P2 = 1.0atm
Note : P2 and T2 are at STP which are 1.0atm and 273.15K
To find V2, we have to use the combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P1 × V1 × T2 = P2 × V2 × T1
V2 = (P1 × V1 × T2) / (P2 × T1)
V2 = (50 × 0.456 × 273.15) / (1.0 × 296.15)
V2 = 6227.82 / 296.15
V2 = 21.029L
Final volume of the gas is 21.03L
Explanation:
Potential because it hasnt released yet
The highest sequence for this shell is the number 2, preceding both the s and p in the diagram. This means that the outermost shell is the second level shell. In this shell, there are 7 electrons, 2 in the 2s orbital and 5 in the 2p orbital.
As a side note (not sure if this is a typo), the electron structure for fluorine begins with a 1s2, not a 1s1.
