Ph measures how acidic or basic something is. The lower the number the more acidic it is going to be.
Drink A is basic, he can drink that
Drink B is neutral, he can drink that
Drink C is acidic, he should avoid
Drink D is basic, he can drink that
Drink E is acidic, he should avoid
Answer:
Na
Explanation:
because sodium has 1 electrons so it loses it to be stable and so have positive charge of 1
Deviation of ideal gas is mainly due to interaction between the particles itself, the more they interact with each other, the more it deviates.
HBr deviate more from ideality because of the high electronegativity of bromine. an ideal gas has molecules that preform elastic collision , because bromine is solo electro negative, it may begin to attract slight positive charge of hydrogen atom on other molecules. H2 does not have dipole moment so would act like an ideal gas.
Answer:
The core turns its hydrogen to helium and stops nuclear fusion which causes the outer shells of hydrogen to collapse.
Explanation:
This results in higher temperature and pressure which in turn causes the outer shells to expand and cool as a red giant.
