Answer:
Explanation:
The equation for this chemical reaction is:
2Ca + O2 -> 2CaO
So 2 moles of Ca react with 1 mole of O2 to form 2 moles of CaO.
Given 3.9 moles of Ca and 2.35 moles of O2,
Ca is the greater reactant as it will be used up.
O2 is the reactant in excess and there will be 2.35 - 3.9/2 = 0.4 moles left.
As mass of 1 mole of O2 is 32g, 0.4 moles of O2 = 0.4 * 32 = 12.8g
Moles of CaO formed = moles of Ca = 3.9
As mass of 1 mole of O2 is 56g, 3.9 moles of CaO = 3.9 * 56 = 218.4g of CaO
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
What gave George W Bush an advantage in the election of 1988 was that he showed more poise, balance, and experience than his rival, Democrat Michael Dukakis.

He promised to have a George H. W. Bush had a more conciliatory approach in his relationship to Middle East foreign affairs.
However, during his administration, he had to break his promise of not raising taxes and that really disappointed the American people.

Answer:
(1,3)
Explanation:
hey, don't have grid paper.
but, all you gotta do is make a table for both equations with
y=3x
x -1 0 1
y -3 0 3
and same goes for the equation
