in the gasious mixture of C4H10,CH4 and CO , C4H10 is 40% of volume .when 200ml of mixture is burns with oxygen gass then what is the volume of CO2?

a pure gass which contains 14.3% hydrogen and 85.7% carbon of total mass.its density is 2.5 gram per leter at 0 degree centigrate and 1 atm.what is it molecular formula?

What happens when 5 g of ice at -20c is added to 5 g of water at 30c. (note:all ice has not changed into water)

50 gram ZnS is burn in the presence of the air then some oxidation doing in it.resultant mass is measure 44 gram.what is the ratio of ZnO and ZnS in resultant mixture?

10 gram of natural gass which contains CH4 and C2H4.when this natural gass is burn in the presence of oxygen then from it we can get some water and 29 gram CO2 gass.then what is the weight of water?

A cylinder containing some gas A is fitted with an idealized piston. Gas A is at 1.2 atm, 10.0 L and at 432K. What external pressure is required to compress this gas irreversibly to a final volume of 3.20L?

If a freezer cools 200 g of water from 20 ºC to its freezing point in 10 minutes, how much heat is removed per minute from the water?

A block of mass M=2.0kg initially at rest at the edge of a frictionless table height h=1.5m is fired at by a bullet of mass m=6g. The bullet embeds in the block, and after impact the block hits the floor a distance d= 2.3m from the bottom of the table. Determine the initial speed of the bullet.

The man of steel is well known of simply bouncing off his chest the bullets and other missiles fired at him. Suppose that a gangster sprays Superman's chest with 5 g bullets at the rate of 110 bullets/min, and the speed of each bullet is 510m/s. Suppose too that the bullets rebound straight back with no change in speed. What is the magnitude of the average force on Superman's chest from the stream of bullets? please show your solution.

Potassium chlorate is often used to generate oxygen gas in high school laboratory. If 183.7g of KClO3 is completely burnt catalytically, what volume of oxygen gas will be obtained at 39 celsius and 1200 torr pressure?
