Answer 1

Answer:

Glycerin

Explanation:

The stronger the intermolecular forces of attraction the more energy is required to break those forces, if you need more energy to break these forces it means that these certain elements would have a higher boiling point. Which is why the answer is Glycerin, the highest boiling point of an element means that it has the strongest forces, which in this case is electrostatic forces.

Answer:

2 moles of C and no more

Explanation:

Consider the following reaction: 2A + 3B --> 2C If you have 2 moles of A and 6 moles of B, what is the maximum number of moles of C that can be made by the reaction

2A + 3B --> 2C '

2 of A make 2 of C if we have atleast 3 of B.

we ave more than enough B

2 of A will make 2 moles of C and no more

A student experimentally determines the gas law constant, R, by reacting a small piece of magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. Based on experimentally collected data, the student calculates R to equal 0.0832

Answers

Due to errors in volume and moles measurement by the student, the true value of the molar gas constant is less than the obtained value.

The Percent error is 1.39%

What is percent error?

Percent error is defined as the ratio of error and true value of a measurement expressed as a percentage.

Percent error = (error/true value) × 100%

Error = |true value - measured value|

The error in the students measurement = |0.08206 - 0.0832|

Error = 0.00114

Percent error = (0.00114/0.08206) × 100%

Percent error = 1.39%

The formula to determine the molar gas constant R is given below:

[tex]R = \frac{PV}{nT}[/tex]

Since the student value is higher than the true value, the possible sources of error include:

The student student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction resulting in increased volumeThe student does not clean the zinc with sand paper, thus the number of moles of hydrogen gas produced is less than the actual value.

Therefore, the true value of the molar gas constant is less than the obtained value.

Determine the wavelength of a radio station transmitting a broadcast at 520 Megahertz.

Answers

The wavelength of the radio station broadcasting at 520 megahertz is 0.58m.

HOW TO CALCULATE WAVELENGTH:

The wavelength of a wave can be calculated by dividing the speed of the wave by its frequency as follows:

λ = v/f

Where;

v= velocity of the wave (3 × 10⁸m/s)f = frequency (Hz)

According to this question, a radio station is transmitting a broadcast at 520 Megahertz. The wavelength is calculated as follows:

λ = 3 × 10⁸ ÷ 5.2 × 10⁸

λ = 0.577 × 10⁸-⁸

λ = 0.58m

Therefore, wavelength of the radio station broadcasting at 520 megahertz is 0.58m.

What is the molality of sodium chloride in solution that is 13.0% by mass sodium chloride and that
the solution has a density of 1.10 g/mL?

Answers

Answer:

2.4 M

Explanation:

1. Suppose you have 100 mL solution:

Use density to find grams of solution:

100 mL solution x (1.10 g / 1 mL) = 110 g solution

2. FInd the amount of sodium chloride pure:

110 g solution x(13 g NaCl / 100 g solution) = 14.3 g NaCl

3. Change grams to mol:

14.3 g NaCl x ( 1 mol NaCl/ 58.44 g NaCl) = 0.24 mol NaCl

4. Molarity:

M = mol NaCl / L solution

M = 0.24 mol NaCl / 0.1 L = 2.4 M

What is an atom?

An atom is defined as the smallest pa of matter which makes a basis of an element. Every form of matter whether it be a solid,liquid , gas consists of atoms . Each atom has a nucleus which is contains protons and neutrons and shells in which the electrons revolve.

The protons are positively charged particles and neutrons are neutral particles and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged particles and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not change the chemical properties of the substances.

How do weak intermolecular bond strengths affect the melting and boiling point of a substance? (Picture is of answers I can choose from)

Answers

B) Both the melting point and boiling point are lower

This is because weak intermolecular forces need less energy for the forces to break compared to strong intermolecular forces. Less energy required means lower temperatures - low melting and boiling points

For a weak intermolecular bond, both the melting point and boiling point are lower.

A lesser energy is required to break bond of weak intermolecular forces while a greater energy is required to break bond of strong intermolecular forces.

E ∝ T

where;

E is the energy required to break the bondT is the temperature

A lesser energy means a lower temperature and a lower temperature will result in lower boiling point and melting point.

Thus, we can conclude that for a weak intermolecular bond, both the melting point and boiling point are lower.
