Which properties do all liquids share?

This diagram shows the forces acting on a car. The center dot represents the car, and the arrows represent the forces acting on

Mariulka [41]

Answer : The correct option is B- Towards the left.

Solution : Given,

Force on car in upward direction, $F_1$ = 6000 N

Force on car in downward direction, $F_2$ = 6000 N

Force on car in right direction, $F_3$ = 5000 N

Force on car in left direction, $F_4$ = 6000 N

Force : Force is equal to the mass multiplied by the acceleration. The force is directly proportional to the acceleration.

Formula : F = m × a

where, F is force, m is mass and a is acceleration.

From the given diagram we conclude that the $F_1$ and $F_2$ are in opposite direction and the force acting on car are same. So, their net force is zero.

And in case of $F_3$ and $F_4$ , the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because $F_4$ is higher than the $F_3$ .

So, the car will accelerate towards left direction.

Methyl isocyanate, H3C-N=C=O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As

statuscvo [17]

Answer:

(a) The lewis structure for methylisocyanate is in the attached.

(b) The carbonyl carbon have an sp² hybridization

(c) The nitrogen have an sp² hybridization?

Explanation:

(a) The lewis structure for methylisocyanate has the nitrogen with one lone pair and the oxygen with two lone pairs.

(b) The carbonyl carbon form double bond with the oxygen causing to form three hybrid orbitals sp².

The Nitrogen also forms a double bond with the carbon having an sp² hybridization too.

A gas mixture contains 3.0 mol of hydrogen (H2) and 7.3 mol of nitrogen (N2). The total pressure of the mixture is 304 kPa. What

Inga [223]

Answer:

Mole fraction H₂ = 0.29

Partial pressure of H₂ → 88.5 kPa

Explanation:

You need to know this relation to solve this:

Moles of a gas / Total moles = Partial pressure of the gas / Total pressure

Total moles = 3 mol + 7.3 mol → 10.3 moles

Mole fraction H₂ → 3 moles / 10.3 moles = 0.29

Mole fraction = Partial pressure of the gas / Total pressure

0.29 . 304 kPa = Partial pressure of H₂ → 88.5 kPa

Two students are given the starting material benzoic acid and are asked to prepare benzaldehyde. The first student starts by ref

Likurg_2 [28]

Answer:

Compound A: Benzoyl chloride

Compound B: Benzaldehyde - (tBuO)₃Al complex

Compound C: Benzaldehyde

Compound D: Benzyl alcohol

Explanation:

The lithium tri-tert-butoxyaluminum hydride that the first student used is a milder reagent than LAH and will stop reacting at the aldehyde.

The LAH that the second student used is much more reactive and will continue to reduce the benzoic acid as far as possible, going all the way to the alcohol.

See the attachment for the reaction steps.
