Answer: The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides

Why does a solution of a weak base and its conjugate acid act as a better buffer than does a solution?

german

Hello!

A solution of a weak base and its conjugate acid act as a better buffer than does a solution of a weak base alone because <span>A solution of a weak base alone has no acid present to absorb added base.</span>

If an acid (In this case HCl) is added to a buffer or a weak base solution, the following reaction happens:

HCl + A⁻ → HA + Cl⁻

In this way, the addition of acid is neutralized by the base.

If a base is added (In this case NaOH), only a solution of a weak base and its conjugate acid can react in the following way:

NaOH + HA → NaA + H₂O

So, a solution of only a weak base can resist the addition of acids but not bases, so it isn't a good buffer.

Have a nice day!

A true statement about mass is that:

Orlov [11]

Answer:

(c.) as the force of Earth's gravity on an object increases, the object's mass increases

Explanation:

Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".

It is mathematically expressed as:

F = $\frac{Gm_{1} m_{2} }{r^{2} }$
