2Cu + S = Cu₂S

S⁰ + 2e⁻ = S⁻²
Cu⁰ - 1e⁻ = Cu⁺¹

A sulfur atom gains two electrons.

cupoosta [38]

Answer:

Following are the responses to the given question:

Explanation:

In the given question the OH could be generated as the H-bond with both the N (nitrogen), which is used to place its N as the partially positive value(+). It is used to simplifies the addition for either its  AA with the imine C. In the above H-bond, the w N is not required as the possibility to use the OCH3

(N2 &amp; O2 &amp; Ar &amp; CO2...) <br> an element compound or mixture?
ololo11 [35]

Answer: Mixture

Explanation:

Element is a pure substance which is composed of atoms of similar elements.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air which conatins a mixture of N_2, O_2 , Ar and CO_2

The pH at the equivalence point in any titration is the pH of the salt solution formed. At the equivalence point of the titratio
olya-2409 [2.1K]

Answer:

D. > 7

Explanation:

Benzoic acid, HX, is a weak acid that reacts with OH- as follows:

HX + OH- → X- + H2O

<em>Where X- is produced, the conjugate base of benzoic acid.</em>

As benzoic acid is a weak acid, benzoate ion is a strong base. A strong base has pH > 7. Right option is:

D. > 7

How can a charged atom (an ion) attract a neutral atom? 1. the charged atom can hit the neutral atom and make it positively char
Ivan
The answer would be 2. <span>an ion polarizes a nearby neutral atom, so that the part of the atom nearer to the ion acquires a charge opposite to the charge of the ion, and the part of the atom farther from the ion acquires a charge of the same sign as the ion

In neutral atoms, the negative and positive charge spread evenly. The charge from an ion could create an electric field that will attract the charge of the neutral atoms.
The neutral atoms charge sum still zero, but the distribution of charge could be changed.</span>

Which postulate of Dalton's atomic model was later changed and why?
telo118 [61]

Answer:

Explanation:

Part two of Dalton's theory had to be modified after mass spectrometry experiments demonstrated that atoms of the same element can have different masses because the number of neutrons can vary for different isotopes of the same element. ... Scientists have even developed the technology to see the world on an atomic level!

hoped i helped you :)
