A spacecraft is traveling at a speed of 2.3 km/sec. It takes 2.5 minutes to pass a small asteroid. how wide is the asteroid (i.e

lidiya [134]

Answer: The spacecraft traveled 345 km during the given time.

Explanation:

To calculate the distance of spacecraft, we use the equation:

$\text{Velocity}=\frac{\text{Distance}{\text{Time}}$

We are given:

Velocity = 2.3 km/sec

Time = 2.5 mins = 150 sec (Conversion factor: 1 min = 60 sec)

Putting values in above equation, we get:

$\text{Distance}=(2.3km/s\times 150s)=354km$

Hence, the spacecraft traveled 345 km during the given time.

Tell whether the following pairs of compounds are identical, constitutional isomers, stereoisomers, or unrelated. (a) cis-1,3-Di

Aleks04 [339]

Answer:

(a) Constitutional Isomers

(b) Constitutional Isomers

Explanation:

Constitutional isomers are also known with the name Structural Isomers. These are the compounds which have same chemical formula but differ in arrangement of atoms i.e. structure.

Both the compounds cis-1,3-dibromocyclohexane and trans-1,4-dibromocyclohexane have the same chemical formula $C_{6} H_{10} Br_{2}$ but have different structure as shown in the image below.

In the second case the compounds 2,3-dimethylhexane and 2,3,3-trimethylpentane, both have same chemical formula $C_{8} H_{18}$ but have different structures which is shown in the image below.

Thus it is clear that in both the groups (a) and (b) the given compounds are Constitutional Isomers.
