How to destermine the isotope

Chemistry
1 answer:
viktelen [127]3 years ago
8 0

Answer:

See the explanation below, please.

Explanation:

Isotopes correspond to atoms with the same atomic number (Z) but different mass numbers (A), that is, they differ in the number of neutrons. Ex Carbon 14 and Carbon 12, Hydrogen and Deuterium.

Isotopes can be determined using the mass spectrometry technique, measuring the relative abundance of each ion (gives us the m / z, ratio between mass and charge).

disa [49]

Answer:

specific heat = 0.951 j/g·°C

Explanation:

Heat flow equation  => q = m·c·ΔT

q = heat flow = 4817 joules

m = mass in grams = 140 grams Aluminum

c = specific heat = ?

ΔT = Temperature Change in °C = 98.4°C - 62.2°C = 36.2°C

q = m·c·ΔT => c = q/m·ΔT = 4817j/(140g)(36.2°C) = 0.951 j/g·°C

lara [203]

Answer:

phosphodiester bond

Explanation:

<em>Phosphodiester linkage/bond is found in deoxyribonucleic and ribonucleic acids. It is formed from a reaction involving the elimination of water from a reaction involving the hydroxyl groups of two different 5-carbon (pentose) sugars and a phosphate group.</em>

The elimination of water, also known as condensation reaction occur twice, resulting in the formation of two ester bonds which then bind the phosphate group to the pentose sugars to become a phosphodiester bond.

The bond links the 3'-hydroxyl group of one of the pentose sugars and the 5'-hydroxyl group of the other pentose sugar in the nucleotides that make up nucleic acids.

What causes some atoms of the same element to have different atomic masses?
Vladimir79 [104]

Answer: Some atoms of the same elements that have different atomic masses are called isotopes

Explanation:

so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.
