____________ are compounds that contain a carbon-carbon triple bond.

Chemistry
1 answer:
Ganezh [65]3 years ago
4 0

Answer:

  • <u>Alkynes</u> <em>are compounds that contain a carbon-carbon triple bond</em>.

Explanation:

  • The simplest organic compounds are formed excluseively by carbon and hydrogen. They are named hydrocarbons.

  • There are 3 main types of hydrocarbons, namely alkanes, alkenes and alkynes.

  • Alkanes posses only single bonds and have general formula Cₙ H₂ₙ ₊ ₂. E.g.: CH₃ - CH₃ (ethane).

  • Alkenes have one or more double bonds between pairs of carbon atoms. E.g.: CH₃ - CH = CH₂ (propene).

  • Alkynes contain one or more triple bonds between pairs of carbon atoms. E.g.: CH ≡ CH (ethyne or acethylene).

  • Both alkenes and alkynes are named unsaturated hydrocarbons, because they have less hydrogen atoms than they could (if they only hade single bonds),  while alkanes are saturated hydrocarbons.

for the substituted cyclohexane compound shown, identify the atoms that are trans to the bromo substituent.
hodyreva [135]

Substituents are trans to each other if the appear on opposite sides in the structure. C, E, G, H and K are trans to the bromo substituent.

The substituted cyclohexane compound is shown in the image attached. Two substituents in a compound are trans to each other if they appear on opposite sides of the structure. Cis substituents appear on the same side of the structure.

Considering the structure as shown in the image attached, the substituents that are trans to the bromo substituent are the substituents shown as letters C, E, G, H and K. They lie opposite to the bromo substituent.

Tris base has a molecular weight of 121 g/mol. How many grams of tris base would you need to make 250ml of a 200mM SOLUTION
STatiana [176]

Answer:

6.05 g

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity

V = volume of solution in liter ,

n = moles of solute ,

From the question ,

M = 200mM

Since,

1 mM = 10⁻³ M

M = 200 * 10⁻³ M

V = 250 mL

Since,

1 mL = 10⁻³ L

V = 250 * 10⁻³ L

The moles can be calculated , by using the above relation,

M = n / V  

Putting the respective values ,

200 * 10⁻³ M = n / 250 * 10⁻³ L

n = 0.05 mol

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molecular mass .

From the question ,

m = 121 g/mol

n = 0.05 mol ( calculated above )

The mass of tri base can be calculated by using the above equation ,

n = w / m  

Putting the respective values ,

0.05 mol = w / 121 g/mol

w = 0.05 mol * 121 g/mol

w = 6.05 g

17.<br> What do you know about a chemical compound by looking at its chemical formula
Bas_tet [7]

Answer:

The number and the kinds of atoms in the compound

Explanation:

  • A chemical formula of a compound contains symbols o the atoms of the elements present in the compound as well as the number of atoms of each element in the form of subscripts.
  • Therefore it helps us to know the elements in a compound and the number of atoms in the compounds.
