33 - 15 = 18
This element is P-33
Answer:
The Kc of this reaction is 311.97
Explanation:
Step 1: Data given
Kp = 0.174
Temperature = 243 °C
Step 2: The balanced equation
N2(g) + 3H2(g) ⇌ 2NH3(g)
Step 3: Calculate Kc
Kp = Kc *(RT)^Δn
⇒ with Kp = 0.174
⇒ with Kc = TO BE DETERMINED
⇒ with R = the gas constant = 0.08206 Latm/Kmol
⇒ with T = the temperature = 243 °C = 516 K
⇒ with Δn = number of moles products - moles reactants 2 – (1 + 3) = -2
0.174 = Kc (0.08206*516)^-2
Kc = 311.97
The Kc of this reaction is 311.97
Answer:
D. nucleus
Explanation:
In human cells, most DNA is found in a compartment within the cell called a nucleus.
They help keep you hydrated, so many athletes consume drinks like Gatorade and Powerade to keep them hydrated
The world's largest mass extinction was the Permian-Triassic event about 250 million years ago, which wiped out 95% of earth's species. It marked the end of the Paleozoic era …and the beginning of the Mesozoic.
