Based on what you know about matter explain why the food coloring mixes at different rates
emmasim [6.3K]

Answer:

Matter has different densities. Different food colorings have different densities. Those with a higher density will sink to the bottom and mix much easier than one with a lower density. The higher density also contains more particles making it easier to mix or give it a fuller color.

What is the<br> total charge of 1 proton, 1 electron, and 1 neutron?
iragen [17]

Given parameters:

Number of protons  = 1

Number of electrons = 1

Number of neutrons  = 1

unknown:

Total charge = ?

Atoms are made up of elementary particles of protons neutrons and electrons.

Protons are the positively charged particles in an atom

Electrons are the negatively charged particles

Neutrons do not carry any charges

To find the total charge on an atom; simply find the difference between the number of protons and electrons.

       Total charge  = Number of protons - number of electrons

                               = 1 - 1

       Total charge is 0

Therefore, the total charge is zero, 0
