Answer:
Carbon dioxide is a chemical compound composed two oxygen atoms covalently bonded to one carbon atom. Carbon dioxide's molecular shape is linear. Also carbon dioxide exists in Earth's atmosphere as a gas. Carbon Dioxide- CO2 makes up one of the gases in our atmosphere.
Explanation:
ΔG = -nEF
ΔG = Gibbs free energy change
n = moles of electrones participated in
E = Electrode potential
F = Faraday constant
By substituting,
ΔG = -(3 mol) x 96485 A S/ mol x (-0.46) V
= + 133149.3 J
= + 133 kJ
Hence the answer is "b".
Since ΔG is a positive value, the reaction is non spontaneous reaction.
500 J (I've had the same question before so I know what answers there are... lol)
The answer is 0 Newtons
This is because of a key word in the question: “constant”
When we say something has a constant speed, that means that its acceleration is 0.
Using the equation derived for Newton’s 2nd law, we see that F=ma
Force = mass x acceleration
If acceleration, a, equals 0, then when we multiply our mass times acceleration 0
F=m(0)
Anything times zero equals zero
So, F=0
Answer:
N2, O2 and Br2
Explanation:
N2, O2 and Br2 are formed of two atoms, so they are diatomic
