Answer:

His mistake was that he also gave the plants  in the music room some fertilizer

Explanation:

When carrying out a reliable experiment, the only variable should be the question being tested. The question here is whether playing music for plants helps them grow faster. Therefore, all the plants should be grown in exactly the same conditions apart from the presence or absence of music.

However, Jo also added fertilizer to the plants in the room where music was playing. Therefore, we don't know whether the fertilizer or the music caused the plants to grow faster.

Instead, Jo should have not given fertilizer to any of the plants, or given fertilizer to all the plants.

Both hydrogen sulfide (H2S) and ammonia (NH3)
faust18 [17]

Answer: The molar mass of H2S is greater than the molar mass of NH3, making the velocity and effusion rate of NH3 particles faster.

Effusion rate is inversely proportional to molar mass.

NH3 will have a higher average molecule velocity, so it will diffuse faster and will reach the other side of the room more quickly.

Why are tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring
Sveta_85 [38]

Answer:

Tigers and lions able to mate to produce cubs,but those cubs would not be able to go on to produce any off spring because their sex chromosomes do not match.

Explanation:

  • Tigers and lions mate to produce ligers and tilons but they do not produce viable sperms or egg.
  • In an organism there are two copies of chromosomes present in the somatic cells.
  • But in case of sex cells they receive each set from mother and father. which they duplicate and divide during formation of gametes via meiosis.
  • in such case if the sets are recieved from two different species then after pairing a mismatch will occur in the gene loci.For example, a eye colour gene may correspond to a paw length gene.
  • Thus the gametes when produced will not be viable.

How many moles are in 9.50 x 1022 molecules of CO? Be sure to ALL work below and report your answer using the correct number of
eimsori [14]

Answer:

0.158 moles

Explanation:

We are given;

9.50 x 10^22 molecules of CO

We are required to determine the number of moles;

We need to know;

1 mole of a compound = 6.022 × 10^23 molecules

Therefore;

9.50 x 10^22 molecules of CO will be equivalent to;

= 9.50 x 10^22 molecules ÷ 6.022 × 10^23 molecules/mole

= 0.158 moles

Therefore, the number of moles are 0.158 moles
