2 years ago a 4.00 l flexible container holds a sample of hydrogen gas at 153 kpa. if the pressure increases to 203 kpa and the temperature remains constant, what will the volume be?

Answers

Answer 1
Answer:

To solve this we assume that the gas is an idealgas. Then, we can use the ideal gas equation which is expressed as PV = nRT. Ata constant temperature and number of moles of the gas the product of PV isequal to some constant. At another set of condition of temperature, theconstant is still the same. Calculations are as follows:

 

P1V1 =P2V2

 V2 = P1 x V1 / P2

 V2 = 153 x 4 / 203

 V2 = 3 L

How is the relative abundance calculated?

Answers

Atomic weights are weighted averages calculated by multiplying the relative abundance of each isotope by its atomic mass and then summing up all the products.

Is combustion an example of the law of conservation of matter and why?

Answers

Answer:

Explanation:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted.

Which is not true of binary compounds?

Answers

The answer is: The name of the positively charged nonmetal ion is changed to end in –ide.

For example, a chemical compound containing sodium and chlorine is binary ionic compound sodium chloride (NaCl).

In this compound, sodium (Na) has positive charge and chlorine (Cl) has negative charge.

Chlorine is nonmetal and sodium is metal.

Metals have positive charge and nonmetals negative.
The name of the positively charged nonmetal ion is changed to end in –ide, is not true of binary compounds.

How does the law of conservation of matter apply to chemical equations

Answers

Since the law of conservation of matter says that no matter can be created or destroyed, chemical equations must have the same amount of matter after the reaction as there was before, making them balanced.
