Describe the three subatomic particles (protons, neutrons, and electrons) in terms of their mass, charge, and location within th
atroni [7]
Particle      mass                          charge                     location

protons     1.673*10 ^ - 27 kg        1.6*10 ^ -19 C        in the nucleus
neutrons   1.675*10 ^ - 27 kg        0                             in the nucleus
electron     9.11 * 10 ^ - 31 kg       -1.6 * 10 ^ - 19 C    around the nucleus (orbitals)

Protons and neutrons have almost same masses. Mass of electrons is 1/1840 the mass of the protons.

Protons and electrons have the same magnitud of charge with different sign. Protons are positive and electrons are negative. Neutrons do not have charge.

How many 20.0-g ice cubes are required to absorb 47.0 kJ from a glass of water upon melting?
Sati [7]

Hello!


The number of 20-g ice cubes required to absorb 47 kJ from a glass of water upon melting is 7 icecubes


Why?


We are going to clear from the equation of the released heat, the mass of ice (m). The specific latent heat of fusion of ice is 336 kJ/kg:


Q=m*L\\ \\ m=\frac{Q}{L}=\frac{47 kJ}{336 kJ/kg}=0,1399 kg=139,88 g\\   \\ 139,88g*\frac{1 icecube}{20g}=6,99=7icecubes


So, 7 ice cubes are required to absorb that amount of heat from the glass of water.


Have a nice day!

What is the difference between cell and cellmembrane​
lisov135 [29]

Answer:

So, a cell, in easiest terms, is "the building blocks of life". Without cells, humans, plants, animals, and anything else that has a cell would not be able to survive. Cells are extremely important to our bodies. Whereas a Cell Membrane is an organelle inside a cell. The Cell Membrane's job is to provide protection for the cell, as well as deciding which substances can enter and exit the cell.

I hope this helps!
