Answer: C
Explanation:
Some poly nuclear aromatic hydrocarbons are not carcinogenic in themselves. However, when these are made to interact with living cells, enzymes in the cells could convert the polynuclear aromatic hydrocarbon into a carcinogenic material such as benzo-[a]-pyrene. This can now interact adversely with the deoxyribonucleic acid of living cells leading to genetic mutation, that is, irreversible changes in the genes of organisms.
As you exercise you sweat to cool yourself down meaning your body looses salt and water in the process of sweating
Answer:
24.28 kPa
Step-by-step explanation:
You want to convert atmospheres to kilopascals.
The conversion factor is 101.325 kPa = 1 atm
p = 0.2396 atm × (101.325 kPa/1 atm)
p = 24.28 kPa
Answer:
Explanation:
The concept applied is the conductivity as it relates to the dissociation and the number of ions in solution. BaCl2 and KBr are ionic solids that will dissociate completely in water to give trivalent and divalent ions respectively.
Benzoic acid on the other hand is a weak acid as such it will not dissociate in water. sugar is a covalent compound.
Hence BaCl2 will have the highest conductivity based on the aforementioned reasons, then followed by KBr ; BaCl2 > KBr > C6H5COOH > C6H12O6
Answer:
ll matter is composed of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.
Each atom is uniform, homogeneous, colorless, tasteless, and indivisible.ll atoms of a given element are identical in mass and properties. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atom.
