Answer:

its 0.163 g

Explanation:

From the total pressure and the vapour pressure of water we can calculate the partial pressure of O2​

PO 2 =P t −P H 2 O

​= 760 − 22.4

=  737.6 mmHg

From the ideal gas equation we write.

W= RT/PVM = (0.0821Latm/Kmol)(273+24)K(0.974atm)(0.128L)(32.0g/mol/) =0.163g

oksano4ka [1.4K]

Answer:

The true statement is:

They are formed when atoms of different elements combine.

Explanation:

Compounds are formed when atoms of different elements combine.

Atoms of different elements combine with each other to attain stable electronic configuration.

The atoms can combine with each other in two different ways:

1) By sharing the electrons

2) By exchanging electrons

When they share electrons with each other, they form a covalent bond.

When they exchange electrons, they form an ionic bond.
