Answer:
21418100
Explanation:
2.14181 are remove point then give 14181/100000 then 10^7= 10000000 and solve it 14181/100000*10000000
HCO3^1- because sodium has a 1+ charge
Answer:
ΔG° is negative and ΔE° is positive
Explanation:
A galvanic cell produces electrical energy from spontaneous electrochemical processes.
In a galvanic cell, ∆E° is always positive since the reaction is spontaneous at room temperature.
Generally in thermodynamics, a negative value of ∆G shows a spontaneous chemical process. Hence in a galvanic cell, ΔG° is negative and ΔE° is positive.
Answer:
False
Explanation:
When electrons move from lower to higher electron energy level they absorb the energy. When they move from higher to lower energy level they emit energy.
Kinetic energy is defined as the energy the object possess due to its motion. It is the work that accelerates a given body from rest to motion.
Given:
The mass of the canoe is 23 kilogram
The velocity of the canoe is 3 m/s
The kinetic energy can be given by the formula:
KE =
Substituting the given values in the kinetic energy equation
KE =
KE= 11.5 * 9 kg.m^2/s^2
k = 103.5 J
Therefore the kinetic energy of the canoe is 103.5 Joules.
