Answer:

The order of increasing bond lenght :

-C≡C < -C=C < -C-C

Explanation:

Bond length is defined as average distance between two nuclei of  bonded atoms in a molecule.Bond length is inversely  proportional to the number of bonds present between two atoms.

\text{Bond length} \propto \frac{1}{\text{Number of bonds}}...[1]

Bond energy is defied as amount of energy required to break apart the bond of 1 mole of molecule into their individual atom.

Bond energy is directly proportional to the number of bonds present between two atoms.

\text{Bond Energy} \propto \text{Number of bonds}..[2]

From [1] and [2]:

\text{Bond length} \propto \frac{1}{\text{Bond energy}}

Bond : Energy (kJ/mol)

-C-C : 346

-C=C : 612

-C≡C : 835

The order of decreasing bond energy :

835 kJ/mol   > 612 kJ/mol > 346  kJ/mol

The order of increasing bond lenght :

-C≡C < -C=C < -C-C

In the chemical equation: NO(g) + ½Cl2(g) → NOCl(g) How many moles of NOCl(g) are in the balanced chemical equation? fill in bla
Mrrafil [7]

Answer:

1

Explanation:

The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.

If no coefficient is shown, we assume it is 1.

NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.

An isotonic solution has: a)The same pH as blood b) More ions per unit volume than blood c) More water per unit volume than blo
Veronika [31]

Answer:

d) osmotic pressure equal to that of blood

Explanation:

Answer is not a) because pH is concentration of positive hydrogen in solution but it not note all solutes. Answer is not b) because like answer a), it not note solutes without charge and, additionally it not note the pressure equilibrium when solvent flows through a membrane . Answer is not c) because it can be more or less water (solvent).

How many grams of KF are in 2 liters of a 3.0 M solution of KF
Rufina [12.5K]

Answer:

mass ( g ) = 348 g

Explanation:

First you know : M = mole / volume (L)

in question you have the M and V and the formula of SUBSTANCE ( KF )

first you get the number of mole from equation above

so 3 = no of mole / 2

no of mole = 3 × 2 = 6 moles

and the moles equation is no of moles = mass ( g ) / molecular weight ( g/mole )

so you have already calculate the moles and you can know the MW from the Question

Mw of KF = 39 + 19 = 58

so n = mass / MW

so 6 = mass / 58

mass ( g ) = 348 g

GOOD LUCK
