I want to know does 6.02 is the right answer for that question. When two atoms of 2H are fused to form one atom of 4He, the total energy evolved is 5.42×10-12J. What is the total change in mass (in kg) for this reaction? Your answer will be on the order of x10-29. Please only give the mantissa (the number that goes along with the x10-29) in your answer. 6.02

An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 44.0 keV. One of the helium atoms is found to be moving in the positive x direction. Find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. Solve...

a)
The water molecule consists of two hydrogen atoms and one oxygen
atom. Since the oxygen atom has a higher electronegativity than the
hydrogen atom, the side of the molecule with the oxygen atom has a
partial negative charge.
Assume that the partial positive charge on each hydrogen atom is
Q2 = 0.512 x 10-19 C. What is the
electric charge Q1 on the Oxygen atom?
b)
The water molecule forms an angle, with hydrogen atoms at the
tips and...

An atom of beryllium (m 8.00 u) splits into two atoms of helium (m-4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moves in the positive x direction and has kinetic energy 59.9 keV. One helium atom is found to move at an angle of 31° with respect to the x axis. Find the direction of motion of the second helium atom and find the velocity of each helium atom Work this problem in the...

It takes four hydrogen nuclei to create one helium nucleus in the proton-proton chain, which is the main energy source of the Sun. If a single hydrogen nucleus has a mass of 1.6726 x 10-27 kg and a single helium nucleus has a mass of 6.6447 x 10-27 kg, how much mass is converted into energy to create four helium nuclei? 06 mass converted into energy: How much energy is generated in creating four helium nuclei? energy generated:

Optical tweezers use light from a laser to move single atoms and
molecules around. Suppose the intensity of light from the tweezers
is 1000 W/m2, the same as the intensity of sunlight at
the surface of the Earth.
(a) What is the pressure on an atom if light from the tweezers
is totally absorbed?
