Which of these gas samples will be the largest at STP?

Which of these gas samples will be the largest at STP?

Which one of the following gas samples has the highest volume at STP

Helium

Which has maximum volume of STP?

It is obvious that 8 moles (or more) of H have the largest volume at STP. Option A, 8 mole H, is the best option. Notice: This is the standard molar volume for any gas at STP.

What volume of oxygen at STP can be produced?

8. 25 litres

What is the weight of oxygen required for the complete combustion of 2.8 kg of ethylene?

9.6 kg

What is the weight of air required for the complete combustion of 2.8 kg of ethylene assume that air contains 25% oxygen by mass?

0.028 kg (Molar mass of ethylene) needs 3 x 0. 032=0. 096 kg of oxygen. 0.25 kg of ethylene is required (0. 096/0.028)=3. 42 kg of oxygen. This means that 2.8kg of ethylene is required (3. 42 x 2.8)=9.6 kg of oxygen.

What is the molar mass of oxygen?

15. 999 u

What mass of oxygen is required in the complete combustion of 450 grams of ethane?

The amount of oxygen needed to complete the combustion of 3 kg ethane is. (1) 11.2 kg.

What mass of oxygen is consumed by the complete combustion of 21.0 grams of ethylene?

Read:  What does "fat free" mean on a food label

28. 054 g

When 100g of ethylene polymerizes to polythene according to the equation?

when 100 g of ethylene polymerises entirely to polythene, the weight of polythene formed as per equation nCH2=CH2 -> (CH2 – CH2)n is. singhalvishi27 is waiting for your help. Earn points by answering the question.

When 100g of ethylene Polymerises entirely to Polyethene the weight of Polyethene formed as per the equation?

When 100 g of ethylene polymerises entirely to polyethene, the weight of polyethene formed as per the equation, nCH2=CH2-(CH2-CH2)n is 100 g, because entire mass of ethylene is converted to polyethylene as there is no addition, elimination or condensation of simple molecules.

How many Litres of oxygen at STP is required for complete combustion?

4 litres=84 litres.
