State each of the following statement true or false? A. A carbon atom can form up to four covalent bonds. B. A carbon atom has s

ix electrons in its outermost shell. C. The bond between a carbon and hydrogen atom is a polar bond. D. Oxygen and nitrogen have a stronger electronegativity than carbon (e.g., a strong pull on a shared electron). E. Bonds between carbon and other atoms are relatively unstable and readily dissociate, resulting in the formation of new molecules. F. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds. G. The carbon backbone of a molecule comes in a variety of shapes: linear, ring-like, or highly branched. H. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.

Answer:

The answer to your question is below

Explanation:

A. A carbon atom can form up to four covalent bonds. True

B. A carbon atom has six electrons in its outermost shell. False, a  carbon atom only has 4 electrons in its outermost shell.

C. The bond between a carbon and hydrogen atom is a polar bond. True

D. Oxygen and nitrogen have a stronger electronegativity than carbon (e.g., a strong pull on a shared electron). True, carbon electronagativity is 2.55, while oxygen and nitrogen electronegativities are 3.44 and 3.04.

E. Bonds between carbon and other atoms are relatively unstable and readily dissociate, resulting in the formation of new molecules. False, carbon bonds are very stable.

F. The carbon backbone of a molecule is made up of a string of carbon atoms held together with either single or double bonds. True, carbon can form strings with single, double or triple bonds.

G. The carbon backbone of a molecule comes in a variety of shapes: linear, ring-like, or highly branched. True, carbon molecules can form a great variety of shapes.

H. Carbon is a relatively large atom allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile. False, carbon atom is a small molecule.

A gas is collected at 30 Celsius and has a pressure of 200 kPa. What pressure would it exert if the temperature changed to 40 Ce
garik1379 [7]

Answer:

206.6\ \text{kPa}

Explanation:

P_1 = Initial pressure = 200 kPa

P_2 = Final pressure

T_1 = Initial temperature = 30^{\circ}\text{C}

T_2 = Final temperature = 40^{\circ}\text{C}

We have the relation

\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}

The pressure that would be exerted after the temperature change is 206.6\ \text{kPa}.

Which of the following radioactive emissions is the least penetrating?
3241004551 [841]

Answer:

alpha particles

Explanation:

alpha particles the least penetrating but potentially most damaging and gamma rays the most penetrating. A beta particle, also called beta ray or beta radiation, is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.

Select the keyword or phrase that will best complete each sentence. must undergo addition because they have easily broken tt bon
STatiana [176]

Alkenes must undergo addition because they have easily broken tt bonds.

Markonikov's rule states in the addition of HX to an unsymmetrical alkene, the H atom bonds to the less substituted carbon atom.

alkenes are unsaturated hydrocarbons because they have fewer than the maximum number of hydrogen atoms per carbon.

Alkyl halides have good leaving groups and therefore readily undergo substitution and elimination reactions.

In hydroboration, the boron atom bonds to the substituted carbon.

Hydroxides, amines and alcoxides undergo substitution and elimination, but can do so only when the heteroatom is made into a good leaving group.
