Answer:
75 years
Explanation:
The heart of the person beats 3.1x10⁹ times. As the heartbeat is 79 beat / min. The minutes the person lives are:
3.1x10⁹ beat * (1min / 79beat) = 3.92x10⁷ min.
1 hour are 60 minutes:
3.92x10⁷ min * (1 hour / 60min) = 6.54x10⁵hours
24 hours are 1 day:
6.54x10⁵hours * (1 day / 24h) = 2.725x10⁴ days.
1 year are 365 days:
2.725x10⁴ days * (1 year / 365 days) = 74.6 years.
In whole years are 75 years
First, draw the Lewis structure for the compound which is shown in the attached picture. From what we can see, there are 4 pairs of electron dots surrounding the As atom. Three of these pairs are bonding each to the other three Cl atoms. The last pair is called a lone pair.
<em>Hence, there is only 1 lone pair for As atom.</em>
Answer: Internal energy is the total kinetic energy and potential energy of all the particles (atoms and molecules) that make up a system.
Explanation:
Internal energy is the total kinetic energy and potential energy of all the particles (atoms and molecules) that make up a system. If a change of state happen, the energy needed for a substance to change state is called latent heat.

Answer:
Forensic drug chemists analyze samples of unknown materials including powders, liquids and stains to determine the chemical identity or characteristics of the compounds that make up the sample. samples submitted as evidence in a drug-related case can contain one compound or a mixture of many compounds.
