Answer:

AB + CD \rightarrow AD + CB is a replacement reaction.

Explanation:

A reaction which involves replacement of chemical species of two or more reactant molecules is known as replacement reaction.

In the reaction, , B is replaced by D and D is replaced by B. Hence, this reaction is a replacement reaction.

A synthesis reaction is a reaction in which two or more species combine to form a single product.

A decomposition reaction is a reaction in which a chemical specie decomposes or breaks to give different products.

Oxidation reaction results in a change in the oxidation state of chemical species involved in the reaction. Therefore, this reaction is not an oxidation reaction as no change in oxidation state is given

we can conclude that is a replacement reaction.

What is the velocity of an object that has been in free fall for 1.5s?

Crank

Answer:

D. 15 m/s downward

Explanation:

v = at + v₀

v = (-9.8 m/s²) (1.5 s) + (0 m/s)

v = -14.7 m/s

Rounded to two significant figures, the answer is D, 15 m/s downward.

A train whistle has a sound intensity level of 70. dB, and a library has a sound intensity level of about 40. dB. How many times

kodGreya [7K]

Answer:

The sound intensity of train is 1000 times greater than that of the library.

Explanation:

We have expression for sound intensity level,

$L=10log_{10}\left ( \frac{I}{I_0}\right )$

A train whistle has a sound intensity level of 70 dB

We have

$70=10log_{10}\left ( \frac{I_1}{I_0}\right )$

A library has a sound intensity level of about 40 dB

We also have

$40=10log_{10}\left ( \frac{I_2}{I_0}\right )$

Dividing both equations

$\frac{70}{40}=\frac{10log_{10}\left ( \frac{I_1}{I_0}\right )}{10log_{10}\left ( \frac{I_2}{I_0}\right )}\\\\\frac{7}{4}=\frac{log_{10}\left ( \frac{I_1}{I_0}\right )}{log_{10}\left ( \frac{I_2}{I_0}\right )}\\\\10^7\frac{I_2}{I_0}=10^4\frac{I_1}{I_0}\\\\\frac{I_1}{I_2}=10^3=1000$

The sound intensity of train is 1000 times greater than that of the library.
