Explanation:
23 are the number of atoms
Answer:
Only Harry and Jena
Explanation:
Under federal regulations, an UST is any one or a combination of tanks such that the volume of an accumulation of regulated substances is 10% or more beneath the surface of the ground.
Any UST system holding a mixture of hazardous waste and other regulated substances are also are not covered by federal regulations regarding USTs.
Farm or residential tank of capacity more than 11 gallons used for storing motor fuel is covered by federal regulations regarding USTs.
According to the given question,
Only Harry and Jena are covered by federal regulations regarding USTs.
Explanation:
A cup of mixtures of iron fillings, sand and salt is a mixture who constituents are in the same phase i.e solid.
To separate them out we use the physical properties of the substances.
- First spread out the mixture uniformly over a piece of paper or on the table.
- Pass a bar magnet over it.
- The iron fillings will become attracted to the magnet and separate from the mixture.
- then pour water into the mixture of sand and salt
- the salt will dissolve since sand is made up of quartz which are highly insoluble.
- separate the water solution. Evaporate to dryness and recover the salt.
- the sand is left behind and dried.

Molarity = number of moles/Volume (L). Solve for the number of moles in the initial solution (3.78M = n/0.3 L) and then use that amount of moles and the new volume (0.5 L) to solve for the new Molarity.
Answer:
Only species Y is anaerobic.
Explanation:
- Cellular respiration refers to the process in which food substances such as glucose are broken down to yield energy in the form of ATP, water and carbon dioxide as by-products.
- Respiration may be either anaerobic or aerobic respiration.
- Aerobic respiration is a type of respiration that takes place in the presence of oxygen. Nutrients are broken down to yield energy, water, and carbon dioxide.
- Anaerobic respiration occurs in the absence of oxygen to yield few molecules of ATP, alcohol and carbon dioxide.
- Therefore; species X carries out aerobic respiration while species Y carries out anaerobic respiration.
