Different rocks have______ melting points

weeeeeb [17]

Answer:

<em>Different rocks have high, medium, and low melting points.</em>

Explanation:

There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

EleoNora [17]

Answer:

a) 50 protons, 50 electrons, 75 neutrons

Explanation:

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

a) 50 protons, 50 electrons, 75 trons

b) 75 electrons, 50 protons, 50 neutrons

c) 120 neutrons, 50 protons, 75 electrons

atomic number IS the number of protons

atomic mass IS the total of protons + neutrons

so 50 protons

125-50 = 75 neutrons

in a neutral atom,

number of negative electrons = number of positive protons

a) 50 protons, 50 electrons, 75 neutrons
