5 carbons are in the molecule. Isotopes are atoms with a constant number of protons but a variable number of neutrons.

<h3>What factors affect an isotope's relative abundance?</h3>

Isotopes are atoms with a constant number of protons but a variable number of neutrons. Atomic masses vary among isotopes.

The proportion of atoms with a particular atomic mass that can be found in a sample of an element that is found naturally is known as the relative abundance of an isotope.

Relative abundance chemistry issues should be solved using the formula below:

(M1)(x) + (M2)(1-x) = M (E)

Issue illustration Determine the relative abundance of the isotopes if the masses of two different nitrogen isotopes are 0.42 amu for carbon-0.42 and 0.065 amu forcarbon-0.065.

Equation x = 0.996 can be found using algebra.

0.42 * 0.996 + 0.065 *0.996 = 0.424794.

5 carbons are in the molecule.

Answer:

Global warming causes sea-level rise as oceans expand, and makes storm patterns more energetic. Consequently it will affect most of the world's coastlines through inundation and increased erosion.

Why can liquid boil at a low pressure?
Paladinen [302]

Answer: I found this online. Hope it helps you.

Explanation:

This pressure is transmitted throughout the liquid and makes it more difficult for bubbles to form and for boiling to take place. If the pressure is reduced, the liquid requires less energy to change to a gaseous phase, and boiling occurs at a lower temperature.

Give explanations for the large drops in melting point from C to Si and from Ge to Sn.
____ [38]

As we move down the group, the metallic bond becomes more stable and the formation of forming covalent bond decreases down the group due to the large size of elements.

Covalent and metallic bonding leads to higher melting points. Due to a decrease in attractive forces from carbon to lead there is a drop in melting point.

Carbon forms large covalent molecules than silicon and hence has a higher melting point than silicon.

Similarly, Ge also forms a large number of covalent bonds and has a smaller size as compared to that of Sn. Hence melting point decreases from Ge to Sn.

The order will be C>Si>Ge>Pb>Sn.

Please help I will give brainliest!
Fiesta28 [93]

Answer:

b, H2O(s) r H2O(g)

Explanation:

entropy is heat, so increase in heat would mean water gets evaporated or melted, or both in this case. so the only choice above that showed increase in heat is from solid(ice) to gas(water vaper) due to increase in heat in the reaction.
