A sample of poisonous carbon monoxide gas, CO, contains 2.50 g carbon and 3.33 g oxygen. The unknown gas X is analyzed and it is determined to be made of 0.75 g carbon and 2.00 g oxygen. Are
these data an example of the law of definite proportions, the law of multiple proportions, or neither?
What does the data tell you about the identity of gas X?

Explanation:

In carbon monoxide ,

2.5 g of carbon reacts with 3.33 g of oxygen

In unknown gas X ,

.75 g of carbon reacts with 2 .00 g of oxygen

2.5 g of carbon will react with 6.66 g of oxygen in X gas .

Ratio of oxygen in two compounds , reacting with same mass of carbon

= 3.33 : 6.66

= 1 : 2 , a simple ratio

It follows law of multiple proportions .

First gas is CO or carbon monoxide

X gas is CO₂ or carbon dioxide .

In this gas , ratio of oxygen reacting with same amount of carbon is doubled .

the answer to your question is c.

if you read the house of usher you should know that the house was haunted

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
