<u>Answer:</u> This chemical reaction is defined as synthesis reaction.

<u>Explanation:</u>

Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to produce a single compound.

The general chemical equation representing this reaction is:

A+B\rightarrow AB

For the given chemical reaction:

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

Hence, this chemical reaction is defined as synthesis reaction.

A buret is filled with 0.1517 M naoh A 25.0 mL portion of an unknown acid and two drops of indicator are added to an Erlenmeyer
antiseptic1488 [7]

Answer:

molarity of acid =0.0132 M

Explanation:

We are considering that the unknown acid is monoprotic. Let the acid is HA.

The reaction between NaOH and acid will be:

NaOH+HA--->NaA+H_{2}O

Thus one mole of acid will react with one mole of base.

The moles of base reacted = molarity of NaOH X volume of NaOH

The volume of NaOH used = Final burette reading - Initial reading

Volume of NaOH used = 22.50-0.55= 21.95 mL

Moles of NaOH = 0.1517X21.95=3.33 mmole

The moles of acid reacted = 3.33 mmole

The molarity of acid will be = \frac{mmole}{volumne(mL)}=\frac{0.33}{25}=0.0132M

If the half-life of a radionulide is 1 month, what percent remains after 4 months?
Aliun [14]

Answer:

6.25% of the original amount

Explanation:

half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.

after 1 month= 50%

after 2 months= 25%

after 3 months= 12.5%

after 4 months= 6.25%
