Atomic number . . .
-- the number of protons in an atom
-- the number of electrons in a neutral atom
-- neutrons are not involved

Atomic mass . . .
-- roughly but not exactly the total of (protons + neutrons) in an atom
-- electrons are not involved

A bottle has a capacity of 1.2 liters. If the density of ether is 0.74 g/mL, what mass of ether can the bottle hold?
AfilCa [17]

Answer:

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:

Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL

Therefore, the correct answer is option B.

How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?
Simora [160]

Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.

Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.

Ek = 1/2 · m(bowling ball) · v²(bowling ball).

m is mass; v is speed of bowling ball.

The standard unit of kinetic energy is the joule.

Elena L [17]

Answer:

Inhibition and tolerance.

Explanation:

Competitive inhibitors are characterized by being chemicals that are similar to the normal substrate. While non-competitive inhibitors are chemicals that bind to the enzyme and alter its shape. This renders the active site of the enzyme ineffective against the substrate. Tolerance makes a society that is fair and equitable.
