How does the light source readout differ from the x-ray readout in the gizmo??

1 answer:

3 0

X-rays differ from the light source readout in terms of the intensity and the possible damage that can be obtained from the two radiation types. The light source readout is more damaging than the X-rays readout in the gizmo. Therefore, precaution is required when handling the light source readout in the gizmo.

Determine the total number of atoms contain in a 2.00 moles of Ni

spayn [35]

Answer:

2.00 moles of Ni has 1.2 *10^24 atoms

Explanation:

Step 1: Data given

Number of moles Ni = 2.00 moles

Number of Avogadro = 6.022*10^23 /mol

Step 2: Calculate number of atoms

Number of particles (=atoms) = Number of Avogadro * number of moles

Number of atoms = 6.022 * 10^23 /mol * 2.00 moles

Number of atoms = 1.2*10^24 atoms

2.00 moles of Ni has 1.2 *10^24 atoms

Which of the following factors affects the amount of heat absorbed by a substance?

Ilia_Sergeevich [38]

Answer:

$\boxed{\text{Specific heat capacity of the substance}}$

Explanation:

The formula for the amount of heat absorbed by a substance is

q = mCΔT

Thus, the three factors are the

mass
specific heat capacity
temperature change

The only factor that is on your list is

$\boxed{\textbf{Specific heat capacity of the substance}}$

The shape of the substance has no effect, nor do its melting and boiling points.
