Explanation:
"Juanita begins to factor an expression as shown.
x² + 3x − 18 = (x + _) (x − _)
What numbers should be placed in the boxes from left to right?"
Use AC method to factor.
1 × -18 = -18
Factors of -18 that add up to 3 are +6 and -3.
The factors are x + 6 and x − 3.
Just took the test and it was 32grams. On my test it was Block B: 32 Grams
4.0
i think it has something to do with molar ratios and finding the limiting reactant
4.0 mol NO * 2 mol NO2/2 mol NO = 4.0 moles of NO2
4.0 mol O2 * 2 mol NO2/1 mol O2 = 8.0 moles of NO2
so the limiting reactant (the reactant that runs out the quickest leaving an excess) is NO
once the limiting reactant is found, we can use that data for that substance to calculate the amount of product
4.0 mol NO * 2 mol NO2/2 mole NO = 4.0 moles of NO2
Answer:
When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapor. Most of the matter in the candle ends up as these two gases.
