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.
Where r the following example at
<span>(4) a chemical change results in the formation of new chemical substances, breaking and creating bonds between atoms. (4) is the only option were you end with different chemical substances (carbon dioxide and water) to what you started with (glucose and oxygen).</span>
Atomic mass Na = 22.99 u.m.a
22.99 g ------------------ 6.02x10²³ atoms
175 g -------------------- ?? atoms
175 x (6.02x10²³) / 22.99 => 4.58x10²⁴ atoms
hope this helps!
When peroxide is swallowed, it generates oxygen bubbles in the stomach. Drinking higher concentrations of hydrogen peroxide can be very dangerous because it can cause tissue burns.
