The more protons in the nucleus, the stronger the attraction of the nucleus to electrons. This stronger attraction makes it more difficult to remove electrons. Within a group, the ionization energy decreases as the size of the atom gets larger.
Answer:
The answer is 0.01365.
Explanation:
C(t) = 0.0225te^?0.0467t
We can derivate,
C'(t) = d/dt ( 0.0225 te^-0.0467t)
after solving,
C'(t) = 0.0225 (e^-0.0467t - (0.0467e^-0.0467t . t)
Plug in t =5,
Answer is C'(t) = 0.01365.
Answer:
Contact with corrosive substances requires flushing with water and removing contaminated clothes and jewelry. With a fire, people should first evacuate the lab. Once safe, they should close doors, pull the fire alarm, and call emergency services. Anyone who is on fire should stop, drop, and roll.
Explanation:
Because that is what you are supposed to do
My freind the best anwer would probably be B
Explanation:
Given -
molar mass = 135.13 g/mol
To Find -
Solution:
we know that -
- molecular mass = n × empirical mass
So,
Here empirical mass =
12.01 + 1.008 + 14.01 = 27.028
Then,
135.13 = n × 27.028
n = 4.99 ≈ 5
We know that,
- molecular formula = n × empirical formula
Then,
molecular formula = 5(CHN)
= C₅H₅N₅
Therefore,
Option A is correct✔
