the second one is equal and opposite
Answer:
Deshydrohalogenation
Explanation:
You are not providing options to answer, however, this can be answered without options.
Now, in the reaction we can see that we have an atom of Bromine in carbon 2, and in the product appears as NaBr. This means that the Br was substracted by elimination. It's an elimination because the final product do not have a substituent where the bromine was, (Like another nucleophyle such OH or another halide). If you look closely the final product, we can see that one hydrogen in carbon 3, is no longer there. So this electrophyle was also substracted, in this case, by a base (Such NaOH), so in this case, it's ocurring an elimination reaction via E2 (One step, bimolecular). So, as the final product has been substracted the nucleophyle and electrophyle, this treaction is a deshydrohalogenation (an atom of hydrogen and a halide were substracted). The mechanism of this, you can see it in the picture.

Answer:
897 mL
Explanation:
This is a problem of dilution. According to the dilution principle, the number of mole before dilution must be equal to the number of mole after dilution. Mathematically:
Molarity x volume (before dilution) = molarity x volume (after dilution)
Before dilution:
Molarity = 0.174 mol/L
Volume = ?
After dilution:
Molarity = 160 mM = 160/1000 = 0.160 M
Volume = 975 mL
Substitute into the dilution equation:
0.174 x volume of sodium carbonate stock = 0.160 x 975
Volume of stock = 0.160 x 975/0.174
= 896.552
To 3 significant digits = 897 mL
The chemist will pour out 897 mL stock solution of sodium carbonate.
