I think the correct answer is the second option. The statement pertaining to the properties of the element vanadium is reliable because the facts presented are testable or can be verified by doing experimentation. Also, nowadays, many studies are present that contains properties of almost anything.
Answer:
Option (C)
Explanation:
Atoms are the basic structures that are combined to form minerals, which are further accumulated giving rise to the formation of rocks. These atoms plays a significant role in the formation of rock and their significant characteristics.
When atoms are passed through the rock cycle, they are not able to move at the same rate, but they can move at a different rate. When a rock changes from one kind to another, its constituent minerals and atoms also alters, forming a different rock type with variable characteristics and properties.
Thus, the correct answer is option (C).
C) can give up electrons more readily than others.
When a neutral hydrogen atom loses an electron, a positively-charged particle should remain.
Answer:
The total pressure of the mixture is 5, 53 atm.
Explanation:
The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law. We convert the unit of pressure in mmHg into atm:
760 mmHg----1 atm
785 mmHg----x= (785 mmHgx 1 atm)/760 mmHg=1, 03 atm
P total= P 02 + P N2
P total= 4, 5 atm + 1,03 atm=<em>5, 53 atm</em>
