kipiarov [429]3 years ago
7 0

Answer:

700000cm

Explanation:

1 km consists of 1000m and 1 m consists of 100 cm so 7×1000×100=700000cm

Answer:

70000 cm in 7km

Explanation:

There are 1000 m and 100 cm in 1 m in 1 km, so to find how many cm are in 7 km you need to do 10000 x 7.  You get 70000

Have a nice day!

How many atoms are there in 24 moles of Fe?
Semenov [28]

Answer: There are 145 \times 10^{23} atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains 6.022 \times 10^{23} atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or,  145 \times 10^{23} atoms

Thus, we can conclude that there are 145 \times 10^{23} atoms in 24 moles of Fe.

Comparing the 2-bromobutane + methoxide and 2-bromobutane + t-butoxide reactions, choose the statements that BEST describe the d
Elina [12.6K]

Answer:

an increase in 1-butene was observed when t-butoxide was used

Explanation:

When a base reacts with an alkyl halide, an elimination product is formed. This reaction is an E2 reaction.

Here we are to compare the reaction of two different bases with one substrate; 2-bromobutane. Both reactions occur by the E2 mechanism but follow different transition states due to the size of the base.

The Saytzeff product, 2-butene, is obtained when the methoxide is used while the non Saytzeff product, 1-butene, is obtained when t-butoxide is used.

The Saytzeff rule is reliable in predicting the major products of simple elimination reactions of alkyl halides given the fact that a small/strong bases is used for the elimination reaction. Therefore hydroxide, methoxide and ethoxide bases give similar results for the same alkyl halide substrate. Bulky bases such as tert-butoxide tend to yield a higher percentage of the non Saytzeff product and this is usually attributed to steric hindrance.
