Answer : A Ketone is an organic compound in which a carbonyl group is bonded to two different carbon atoms.

Explanation :

A Ketone is an organic compound having a structure $R-CO-R^'$ where R and R' can be different carbon containing substituents.

Ketone is a compound in which the a carbonyl group is bonded to the two different carbon atoms which are R and R' and there is a double bond present between the carbon and oxygen atom.

Some examples of ketones are, acetone, propanone, butanone, etc.

Hence, a Ketone is an organic compound in which a carbonyl group is bonded to two different carbon atoms.

Answer: 1. C. polar covalent: electrons shared between silicon and sulfur but attracted more to the sulfur

2. B) $NH_3$

3. B) Fluorine

Explanation:

1. A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Electronegativity difference = electronegativity of sulphur- electronegativity of silicon = 2.5 -1.8 = 0.7

Thus as electronegativity difference is less than 1.7 , the cond is polar covalent and as electronegativity of sulphur is more , the electrons will be more towards sulphur.

2. A molecular compound is usually composed of two or more nonmetal elements. Example: $NH_3$

Ionic compound is formed by the transfer of electrons from metals to non metals. Example: $Mg_3N_2$ , $AlCl_3$ and $LiBr$

3. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here K is having an oxidation state of +1 and as the compound formed is KZ, the oxidation state of non metallic element Z should be -1. Thus the element Z is flourine which exists as diatomic gas $F_2$

zepelin [54]

The frequency of a wave represents B. the number of wave cycles that pass through a specific point within a given time.

The distance between two consecutive crests and the length of a wave are the <em>wavelength</em>.

The distance between the highest and lowest points of a wave is <em>twice the amplitude</em>.

When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 27.6 g of carbon were burned in the presence of

In-s [12.5K]

Answer:

The answer to your question is: 101.2 g of CO2

Explanation:

C = 27.6 g

O₂ = 86.5 g remained 12.9 g

O₂ that reacted = 86.5 - 12.9 = 73.6 g

C + O₂ ⇒ CO₂ The equation is balanced

27.6 73.6 ?

MW 12 32 44

Rule of three

12 g of C------------------ 44 g CO2

27.6 g C ------------------ x

x = 27.6(44)/12 = 101.2 g of CO2

32 g of O2 --------------- 44 g of CO2

73.6 g of O2 ------------ x

x = 73.6(44)/32 = 101.2 g of CO2

atroni [7]

She will most likely observe that the temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles if she measures the temperature of the water in the beaker.
