Explanation:
The total amount of water in the beaker is 0.8 Liters
calculation
convert 300 Ml in liters
that is 1 L = 1000 Ml
? = 300 Ml
by cross multiplication
1 L x300 Ml/ 1000 Ml = 0.3 Ml
total is therefore = 0.5 Ml + 0.3 Ml = 0.8 Liters
Given :
Mass of oxygen containing carbon monoxide (CO) is 2.666 gram .
To Find :
How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O) .
Solution :
By law of constant composition , a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
So , volume of solution does not matter .
Moles of oxygen , .
Now , molecule of CO contains 1 mole of C .
So , moles of C is also 0.167 mole .
Mass of carbon , .
Therefore , mass of carbon is 2 grams .
Hence , this is the required solution .
Answer:
combustion
Explanation:
The enthalpy change for the complete burning of one mole of a substance
is the enthalpy of __combustion_____ .
