levacccp [35]

Answer:

-775 rad/s^2

Explanation:

Knowing the initial and final angular speed is \omega_0 = 440.9 rad/s and \omega = 0 rad/s, respectively. We can use the following formula for equation of motion to calculate the average angular acceleration in t = 0.569 seconds

\Delta \omega = \alpha t

\omega - \omega_0 = \alpha t

0 - 440.9 = \alpha 0.569

\alpha = \frac{-440.9}{0.569} = -775 rad/s^2

Which equation represents a neutralization reaction?
elixir [45]

B  acid + base    →  water + salt

Explanation:

The best equation that represents a neutralization reaction is:

                      acid + base    →  water + salt

In a neutralization reaction, an acid reacts with a base to produce salt and water only.

Here, hydrogen combines with hydroxide to form water.

Titration is usually used to carry out this reaction in the laboratory.

An indicator is added to the base and at end the color of the reaction changes.

At this point the acids have completely been neutralized with the base.
