The answer is (4) butyne. The carbon-carbon triple bond is found in alkynes. And the alkynes has -yne at the end of the name. "-ene" end means that it is alkene and has carbon-carbon double bonds.

Answer: Option (4) is the correct answer.

Explanation:

A hydrocarbon in which all atoms are bonded by single bond and have a general formula $C_{n}H_{2n+2}$ is known as an alkane.

A suffix "ane" adds at the end of the name of this hydrocarbon.

A hydrocarbon in which an atom is bonded by a double bond and have a general formula $C_{n}H_{2n}$ is known as an alkene.

A suffix "ene" adds at the end of the name of this hydrocarbon.

A hydrocarbon in which an atom is bonded by triple bond and have a general formula $C_{n}H_{2n-2}$ is known as an alkene.

A suffix "yne" adds at the end of the name of this hydrocarbon.

Thus, we can conclude that a carbon-carbon triple bond is found in a molecule of butyne.

A 10.0 mL sample of 0.75 M CH3CH2COOH(aq) is titrated with 0.30 M NaOH(aq) (adding NaOH to CH3CH2COOH). Determine which region o

Llana [10]

Answer:

5.75

Explanation:

Weak acid and strong base,

Make it a two part problem

The first will be Partial neutralization of the weak acid, while the second is the equilibrium and final pH

1.Parameters

HC2H3O2 =10mL x 0.75M = 7.5 mmol

NaOH =22mL x 0.30M = 6.6 mmol

R HC2H3O2 + OH- --> C2H3O2- + H2O

I 7.5 mmol 6.6 mmol 0 mmol ignore

C -6.6 mmol -6.6 mmol +6.6 mmol

E 0.9 mmol 0.0 mmol 6.6 mmol

2.) HC2H3O2 --> H+ + C2H3O2-

Initial concentrations

[HC2H3O2]: 0.9 mmol / 32mL = 0.0281M

[H+]:

[C2H3O2-]: 6.6 mmol x 32mL = 0.206M

Concentrations at equilibrium

[HC2H3O2]: 0.0281M - x

[H+]: [C2H3O2-]: 0.206M + x

If x is small and can be ignored except [H+]

Substitute and solve

1.3 x 10-5 = (x)(0.206)

(0.0281)

X= 1.77 x 10-6M => pH = 5.75

Through which of the following ways can heat be transferred?

SashulF [63]

Answer:

The correct option is:

A) by direct or indirect contact between objects at different temperatures

Explanation:

Heat can be transferred in three different methods:

Conduction, Convection and Radiation

Conduction is heat transfer through direct contact between substances at different temperatures.

Convection is the heat transfer which takes place through air currents.

Radiation is the heat transfer that does not require contact between two objects.

Hence, heat transfer can take place through direct or indirect contact between objects at different temperatures.

if .00327 g of gas dissolves in .376 L of water at 876 torr what quantity of this gas will dissolve 759 torr ?

MAXImum [283]

Answer:- Solubility of the gas at 759 torr is 0.00753 g/L.

Solution:- From given data, 0.00327 g of gas is soluble in 0.376 L of water at 876 torr.

Solubility of gas at 876 torr pressure is = 0.00327g/0.376L = 0.00869 g/L

Solubility of gases is directly proportional to the pressure. It means, grater is the pressure, more is the solubility of gases.

So, 0.00869/876 = X/759

Where, X is the solubility of the gas at 759 torr.

X = 0.00869(759)/876

X = 0.00753 g/L
