False bro because i’m smart just listen to me
Answer:
.15 grams of MgO / 40.3 = .0285 moles of MgO. For every mole of Magnesium Oxide, you have one mole of magnesium and one mole of oxygen, therefore,.0285 moles of MgO * (1 mole of magnesium/1 mole of magnesium oxide) = .0285 magnesium.0285 magnesium * (6.022 *10^23 atoms magnesium/1 mole of magnesium) = 1.718*10^22 atoms of magnesium
Explanation:
given its position on the periodic table, the atomic number of boron is 6-1=5
Explanation:
We can tell if a chemical reaction has taken place when one or more of the following things happen:
1.There has been a colour change inside the reaction flask.
2. A gas has formed. Usually we know a gas has formed when we can see bubbles.
3.A solid has formed.
