Answer:

Giving away protons to the water molecules

Explanation:

When acids are mixed with water the following reaction takes place:

H^+(aq) + H2O(l) ------> H3O^+(aq)

Hence when acids are added to water, acids donate a proton to water to form the oxonium ion H3O^+ by coordinate covalent bonding. Note that acids contain the hydrogen ion H^+

Sergeu [11.5K]

Answer:

D. As white light passes through a prism , it bends and separates into different colors

Explanation:

When light enters a prism, it experiences a phenomenon called 'refraction'.

Refraction occurs when light crosses the interface between two mediums with different optical density; when this happens, the light bends and also changes speed.

The angle at which the ray of light is refracted into the second medium depends on the optical density of the two mediums, but also on the wavelength of the light.

In particular, longer wavelengths (red color) are refracted the least, while shorter wavelengths (violet color) are refracted the most.

As a result, when white light (consisting of all the colors of visible light) enters into a prism, they different wavelengths are separated: therefore, white light separates into different colors.

So, the correct answer is

D. As white light passes through a prism , it bends and separates into different colors

A group of students are measuring how the acceleration of a mass will change due to a force.
Fudgin [204]

The graph of the plot of acceleration against force is a straight line graph. Option B

<h3>What is the relationship between force and acceleration?</h3>

From the Newton's second law of motion we can derive that; F = ma

F= mass

a = acceleration.

This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.

As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B

a 5L container contains 3 moles of helium and 4 moles of hydrogen at a pressure of 9 atms maintaining a constant T and additiona
Stells [14]

Answer:

7.71 atm

Explanation:

Given the following data:

V = 5 L

n_{He} = 3 mol

n_{H_2} = 4 mol

p_1 = 9 atm

T = const

According to the ideal gas law, we know that the product between pressure and volume of a gas is equal to the product between moles, the ideal gas law constant and the absolute temperature:

pV = nRT

Since the temperature and the ideal gas constant are constants, as well as the fixed container volume of 5 L, we may rearrange the equation as:

\frac{p}{n}=\frac{RT}{V}=const

This means for two conditions, we'd obtain:

\frac{p_1}{n_1}=\frac{p_2}{n_2}

Given:

p_1 = 9 atm

n_1 = n_{initial total} = n_{He} + n_{H_2} = 3 mol + 4 mol = 7 mol

n_2 = n_{final total} = n_{He} + n_{H_2} = 3 mol + 4 mol + 2 mol = 9 mol

Solve for the final pressure:

p_2 = p_1\cdot \frac{n_2}{n_1}

Now, according to the Dalton's law of partial pressures, the partial pressure is equal to the total pressure multiplied by the mole fraction of a component:

p_{H_2}=\chi_{H_2}p_2

Knowing that:

p_2 = p_1\cdot \frac{n_2}{n_1}

And:

\chi_{H_2}=\frac{n_H_2}{n_2}

The equation becomes:

p_{H_2}=\chi_{H_2}p_2=p_1\cdot \frac{n_2}{n_1}\cdot \frac{n_H_2}{n_2}=p_1\cdot \frac{n_H_2}{n_1}

Substituting the variables:

p_{H_2}=9 atm\cdot \frac{4 mol + 2 mol}{7 mol}=7.71 atm
