14. (question in picture)

The partial pressure of nitrogen gas in the balloon is 391 mmHg

Explanation:

Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the partial pressure of nitrogen gas, we use the law given by Dalton, which is:

We are given:

Total pressure of the lab, = 770 mmHg

Vapor pressure of carbon dioxide, = 379 mmHg

Putting values in above equation, we get:

Hence, the partial pressure of nitrogen gas in the balloon is 391 mmHg

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
