Characteristics that can be observed or measured without changing the chemical nature of the substance. but if you go to quizzlet it could help you too it has flash cards that could help
Explanation:
Answer:
3.52 grams is the theoretical yield of carbon dioxide formed from the reaction of of methane and of oxygen gas.
Explanation:
Moles of methane gas =
Moles of oxygen gas =
According to reaction 1 moles of methane gas reacts with 2 mole of oxygen gas.
Then 0.08 moles of methane will recast with:
oxygen gas
As we can see that moles of methane are in limiting amount , so the amount moles of carbon dioxide will depend upon on moles of methane gas.
Limiting reagent = methane
According to reaction , 1 mole of methane gas gives 1 mol of carbon dioxide gas.
Then 0.08 moles of metahjen gas wuill give :
of carbon dioxide gas.
Mass of 0.08 mople sof carbon dioxde gas :
3.52 grams is the theoretical yield of carbon dioxide formed from the reaction of of methane and of oxygen gas.
Answer:
3.46 g of BaCl2
Explanation:
The equation of the reaction is;
BaCl2(aq) + Na2SO4(aq) --------> 2NaCl(aq) + BaSO4(s)
Number of moles of barium sulphate produced = 3.88 g/233.38 g/mol = 0.0166 moles
From the reaction equation;
1 mole of BaCl2 yields 1 mole of barium sulphate
Hence 0.0166 moles of BaCl2 yields 0.0166 moles of barium sulphate
Hence;
Mass of BaCl2 required = 0.0166 moles × 208.23 g/mol = 3.46 g of BaCl2
Answer:
Third choice.
Explanation:
The age of an object that was once living. More accurately this is obtained by radiocarbon dating, which is a form of radiometric dating.
Answer:
1.14 M
Explanation:
grams/molar mass = ans. / volume
317/110.98=2.86/2.50=1.14 M
