Answer:
![P_4+5O_2\rightarrow P_4O_{10}](https://tex.z-dn.net/?f=P_4%2B5O_2%5Crightarrow%20P_4O_%7B10%7D)
Explanation:
Hello!
In this case, when we want to balance chemical reactions such as in this case, the idea is to equal to number of atoms of each element at each side of the equation according to the lay of conservation of mass, just as shown below:
![P_4+5O_2\rightarrow P_4O_{10}](https://tex.z-dn.net/?f=P_4%2B5O_2%5Crightarrow%20P_4O_%7B10%7D)
Because we have four phosphorous and ten oxygen atoms at each side.
Best regards!
Answer:
E = 1.602v
Explanation:
Use the Nernst Equation => E(non-std) = E⁰(std) – (0.0592/n)logQc …
Zn⁰(s) => Zn⁺²(aq) + 2 eˉ
2Ag⁺(aq) + 2eˉ=> 2Ag⁰(s)
_____________________________
Zn⁰(s) + 2Ag⁺(aq) => Zn⁺²(aq) + 2Ag(s)
Given E⁰ = 1.562v
Qc = [Zn⁺²(aq)]/[Ag⁺]² = (1 x 10ˉ³)/(0.150)² = 0.044
E = E⁰ -(0.0592/n)logQc = 1.562v – (0.0592/2)log(0.044) = 1.602v
The answer is low frequency and long wavelength
A would be states of matter
B would be density
C would be Liquid
J is oxidation
H would be acid
D would be gas
I would be base
thats all i remember
Answer:
the acceleration is 3 k/h/s
Explanation:
The formula for acceleration is Δv/t, so change in velocity divided by time.
The original velocity is 15 kph, and the final velocity is 30 kph. Therefore, the change in velocity is 15 kph. 15/5=3 k/h/s
