Which statement best describes the formation of a solution?
aev [14]

Answer:

A small amount of solute dissolved in a larger amount of solvent.

Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.

List 4 types of information that are given in each box of the periodic table:
omeli [17]
1) the element symbol, and thus name. For example, H is hydrogen, C is carbon and Fe is iron.

 2) The atomic number, which is equal to the number of protons in the nucleus.

 3) Since each proton has a +1 charge, you can also figure out the number of -1 electrons in the neutral atom.

 4) The atomic mass, in atomic mass units, which is an average of 1 or more isotopes of the element.

Which element would have a full outer shell of electrons if it gained three electrons?
Vsevolod [243]

Answer:

Octet Rule is defined as the chemical rule in which atoms tend to form bonds in such a way that it completes its valence shell or tend to achieve the configuration of a noble gas.

Explanation:

The lithium is chemical element, which has atomic number 3. It has one valence electron in its outermost shell, therefore, it will require 7 more electrons to complete its octet.

The element nitrogen has the atomic number 7, such that it has 5 valence electrons in its outer most shell. Therefore, it will require 3 more electrons to complete its octet.

The noble gas Argon have complete octet, such that it does not require any electrons to complete its octet. the gas is inert and non-reactive.

The chemical element Boron has atomic number 5, such that it has three electrons in its outer most shell. Therefore, it will require 5 more electrons to complete its octet.

Hence, the correct option is Nitrogen.

The amino acid methionine can be used as fuel by being converted to succinyl CoA. What would be the estimated ATP yield for the
andre [41]

Answer:

18 molecules of ATP will be produced for the breakdown of methionine to succinyl CoA and the entry of succinyl CoA to the citric acid cycle with no input of glucose.

Explanation:

Reactions                                          reduced co enzymes           ATP formation

α keto glutarate to propionyl CoA      2 NADH                                         6 moles

Succinyl CoA to succinate                                                               2 GTP≈ 2 ATP

Succinate to fumarate                         2FADH2                                      4  moles

Malate to oxaloacetate                        2 NADH                                       6 moles
