Answer:
Solids, liquids and gases all expand when heat is added
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ...
Answer:
Erosion
Explanation:
Because that's what it looks like
Make the equation equal on each side.
With number 1 it says the left side of the arrow has 1 Sn, 2 S, and 2 O.
The right has 1 Sn, 4 O, and 1 S.
So you have to balance the equation by putting numbers in front of the compounds.
SnS2 + O2 = SnO2 + SO2
SnS2 + 3 O2 = SnO2 + 2 SO2
Now there is 1 Sn, 2 S. and 6 O on each side. The large number in front of the compounds essentially multiplies it by that the subscript of that number. So with O2 it says there are 2 Oxygens. So they come in pairs. If you get 3 pairs of Oxygens there will be 6.
The same process goes with the rest of them too. Sometimes it takes a few guesses. Just figure them out like an algebra problem. Put the equal sign between them like I did. It maked it easier for me.
Answer:
The atomic number on the Periodic Table identifies the number of protons in any atom of that element. Copper, atomic number 29, has 29 protons. Finding the atomic number of an element reveals the number of protons.
To find the number of neutrons in the atom, subtract the atomic number from the atomic mass.
