The balanced chemical reaction:
C3H8 + 5O2 = 3CO2 + 4H2O
We are given the amount of the carbon dioxide to be produced. This will be the starting point of our calculations.
<span>43.62 L CO2 ( 1 mol CO2 / 22.4 L CO2 ) (5 mol O2 / 3 mol CO2 ) (
22.4 L O2 / 1 mol O2) = 72.7 L O2</span>
Answer:
105m/3hourz
Explanation:
35 miles per hour, so 3 hours
35x3=105 per 3 hours
Answer:
D . 20 grams reactant U + 3 grams reactant V → 23 grams product W
Explanation:
Law of conservation of mass states:
The mass of a closed system (As a reaction), is neither created or destroyed.
That is, the mass of reactants is equal to mass of products.
A. In reaction A 22g of reactants produce 9g of products. This reaction doesn't illustrates the law of conservation of mass.
B. 10g reactant produce 25g of products. This reaction doesn't illustrates the law of conservation of mass.
C. 19g of reactants produce 180g of products. This reaction doesn't illustrates the law of conservation of mass.
D. 23g of reactants produce 23g of products. -This is the reaction that best illustrates the Law of Conservation of Mass.
Answer:
x = 10/7
Explanation:
2(x + 2) - 4(2x - 3) = 4(2x - 1),
2x + 4 - 8x + 12 = 8x - 4,
-6x + 16 = 8x - 4,
20 = 14x,
x = 20/14 or 10/7
If you mixed chlorine, argon, and sodium together, just by mixing there will be no changes or reaction that would happen since the energy in mixing the substances is not enough to let a reaction happen. However, if enough energy is added to the system sodium and chlorine might react and form sodium chloride.
