1. What kind of intermolecular forces act between a chlorine monofluoride molecule and a hydrogen bromide molecule

Chemistry
1 answer:
Arturiano [62]3 years ago
4 0

Answer:

Dipole- Dipole force.

Explanation:

Here both Chlorine monofloride( ClF) and hydrogen bromide( HBr) both are highly polar molecules. Polar molecules have dipole intermolecular forces. Polar molecules are adhering to their neighbors atom and tend to have higher boiling points, than non-polar molecules. One polar molecule's positive end is drawn by another polar molecule's negative end and vice versa.

The expected value for a chemical equation is 47g of water, after an experiment you find that you have 2.58 moles of water. What
strojnjashka [21]
<h3><u>Answer</u>;</h3>

Actual yield = 46.44 g

<h3><u>Explanation;</u></h3>

1 mole of water = 18 g/mol

Therefore;

The experimental yield = 2.58 moles

equivalent to ; 2.58 × 18 = 46.44 g

The theoretical value is 47 g

Percentage yield = 46.44/47 × 100%

                             = 98.8%

The questions asks for actual yield = 46.44 g

amid [387]

Answer: The correct answer is option (D)

Explanation:

These aurora are also known as polar lights or northern lights( north poles) or southern lights(south pole) .

according to Boyles law if the initial pressure and volume of a gas were five atm for the pressure and 10 mL for the volume and
maks197457 [2]

Answer:The new volume is 5mL

Explanation:

The formular for Boyles Law is; P1 V1 = P2 V2

Where P1 = 1st Pressure   V1 = First Volume

          P2 = 2nd Pressure V2 = Second Volume

From the question; P1 = 5atm, V1 = 10ml

                                P2 = 2 x P1 (2 x 5) = 10 atm   V2 =?  

Using the Boyles Law Formular;  P1 V1 = P2 V2, we make V2 the subject of formular;  P1 V1/ P2 = V2

∴ 5 x 10/ 10 = 5

∴ V2 = 5mL
