Your pattern of breathing increases, making it faster than usual, when you're exercising because you're pushing your body to work harder and speeding up your heart rate making you tired.
When you're resting your breathing pattern should be steady and normal since you aren't doing anything that requires lots of body work or something that would make you out of breath.
Hope this helps,

Answer:
It is not a legitimate chemical name because the methyl group on carbon 1 increases the length of the carbon chain to seven carbon atoms thus making the parent compound heptane
Explanation:
Chemical compounds are named according to rules in the IUPAC nomenclature.
In naming organic compounds, parts of rules is to find out the parent or root compound. This is determined by finding out the longest carbon chain and then checking if it contains single or multiple bonds. (that is if it is an alkane- with single bonds, alkene-with double bonds or an alkyne- with triple bonds)
From the question the parent or root name is an alkane containing 6 (Hex-) carbon atoms, while the methyl group is substituent
(CH₃)-CH₂-CH₂-CH₂-CH₂-CH-CH₃
However the alkyl substituent on carbon 1 increases the the length of the carbon chain to 7 (Hept-) instead of 6. Hence the correct IUPAC nomenclature is heptane and not 1-methylhexane.

Answer:
10 molecules of NH₃.
Explanation:
N₂ + 3H₂ --> 2NH₃
As the N₂ supply is unlimited, what we need to do to solve this problem is <u>convert molecules of H₂ into molecules of NH₃</u>. To do so we use the <em>stoichiometric coefficients</em> of the balanced reaction:
- 15 molecules H₂ * = 10 molecules NH₃
10 NH₃ molecules could be prepared from 15 molecules of H₂ and unlimited N₂.
Answer:
Volume of 6.5 moles of Helium at STP is 145.6954 L
Explanation:
As we know
At STP, temperature is 273.15 K and pressure is 1 atm
n is the number of moles which is equal to 6.5
R is the gas constant = 0.08206 L atm/K mol
Substituting the given values in above equation, we get -
Liters
Volume of 6.5 moles of Helium at STP is 145.6954 L
