Answer:
Atoms will rearrange and for new substances
Explanation:
In a chemical reaction, elements combine their atoms and create new substances. For this to occur, the bonds must break and form new ones with the other atoms.
The amount of CD is 35 g, and the amount of AC is 40 g.
Answer:
Kinetic energies of all the gases are same.
Explanation:
The average kinetic energy of molecules of a gas is given by the formula:
K.E = (3/2)KT
where,
K.E = Average Kinetic Energy of the molecule
K = Boltzman's Constant = 1.38 x 10^-23 J/K
T = Absolute temperature of gas
Since, all the gases are in a mixture, and the temperature of the gases must be same and equal to the temperature of mixture.
Therefore, all the terms in the formula are constant and the <u>Average Kinetic Eenergies of all the gases in the mixture (namely, Neon Ne, Krypton Kr, Radon Rn), equal.</u>
A. Light reflected from the object's surface must enter your eyes.
Answer:
is equal to the action force , but acts in the opposite direction.
Explanation:
- All you need to solve is apply Newton's third law.
It states that
- Every action has an equal and opposite reaction
