Answer:

increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object would make the oppositely charged objects attract each other more.

The formula for finding the density of an object is B. Mass x density = volume.

The formula for finding the density of an object is given by the equation: Density = Mass/Volume. This formula states that the density of an object is equal to its mass divided by its volume. To rearrange the formula to solve for volume, we can multiply both sides of the equation by volume:

Density x Volume = Mass.

From this equation, we can see that mass multiplied by density gives us the volume of the object.

Therefore, the correct formula for finding the volume of an object is Mass x Density = Volume.

Option A (Density + mass = volume) is incorrect because the density and mass cannot be added together to determine volume.

Option C (Density = mass + volume) is incorrect because the formula is missing the division symbol between mass and volume.

Option D (Density x height = volume) is incorrect because height is not a factor in determining the volume of an object based on its density.

The application of force in the direction of the motion of an object. The second scenario involves applying force to a moving item that is traveling in the opposite direction.

A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. A force has both a direction and a magnitude.

Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.

A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects. The force is no longer felt by the two objects when the interaction ends.

Thus, Force applied to an item in motion that originates in any direction constitutes the third situation where force is created.

The process that converts a solid directly to gas is called Sublimation.

The new volume assuming that the pressure and temperature remain constant is 0.46 L and the correct option is option 1.

The Ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation to the behaviour of many gases under many conditions, although it has several limitations. The ideal gas equation can be written as-

                        PV = nRT

where,

P = Pressure

V = Volume

T = Temperature

n = number of moles

Given,

Initial volume = 1.5 L

Initial moles = 7.5 moles.

Moles remaining = 2.3 moles

\(\frac{n_{1} }{V_{1} } = \frac{n_{2} }{V_{2} }\)

\(\frac{7.5}{1.5 } = \frac{2.3}{V_{2} } }\)

V₂ = 0.46 L

Thus, the ideal selection is option 1.

Explanation:

Structural isomer is a type of isomer in which molecules with the same molecular formula have different bonding patterns and atomic organization.

For example Pentan-1-ol, pentan-2-ol, and pentan-3-ol are structural isomers that exhibit position isomerism.

Cyclohexane and hex-1-ene are examples of functional group structural isomers.

These substances have dispersed particles that are large enough to scatter light, making the beam visible. Therefore, out of the options provided, a mixture that scatters light is an example of a colloid. Option B)

A colloid is a type of mixture in which particles are dispersed throughout a medium, creating a homogeneous appearance. Unlike solutions, where the particles are completely dissolved, and suspensions, where the particles settle out, colloids have particles that are larger than those in solutions but smaller than those in suspensions. One characteristic of colloids is that they can scatter light due to the size of the particles. This scattering of light is known as the Tyndall effect. Examples of colloids include milk, fog, and aerosol sprays. These substances have dispersed particles that are large enough to scatter light, making the beam visible. Therefore, out of the options provided, a mixture that scatters light is an example of a colloid. Therefore option B) is correct

The RMS speed of Cl₂ and He molecules at 411 K is 379.97m/s and 1600 m/s

In a gas, the root-mean-square speed is used to calculate particle speed, which is defined as the square root of the common velocity squared of the molecules in the gas. It is represented mathematically as vrms=3RT/M.

The average kinetic energy of gas molecules is proportional to temperature and inversely proportional to molecular weight.

The root mean square(RMS) speed of the molecule in a gas can be calculated using the following formula

Rms speed = √(3RT/M)

Here R is the gas constant, T is the absolute temperature and M is the molar mass of the gas molecule in kg/mol

Now we have to calculate the RMS speed of Cl₂ molecules at 411 K? and the RMS speed of He atoms at 411 K.

At 411 K, the RMS speed of Cl2 molecules is

RMS speed = √(3RT/M)

=√((3 x 8.314 x 411)/(71 x 10-3 ))

=√(10251.162/0.071)

= √144382.563

= 379.97m/s

RMS speed of He molecules at 411 K

RMS speed = √(3RT/M)

=√((3 x 8.314 x 411)/(4 x 10-3 ))

=√(10251.162/0.004)

= √2562790.5

= 1600 m/s

Therefore the RMS speed of Cl₂ and He molecules at 411 K is 379.97m/s and 1600 m/s

There are 0.84 moles of aluminum ions (Al3+) present in 0.42 mol of Al2(SO4)3.

To determine the number of moles of aluminum ions (Al3+) present in 0.42 mol of Al2(SO4)3, we need to consider the stoichiometry of the compound.

The formula of aluminum sulfate (Al2(SO4)3) indicates that for every 1 mole of the compound, there are 2 moles of aluminum ions (Al3+). This means that the mole ratio of Al3+ to Al2(SO4)3 is 2:1.

Given that we have 0.42 mol of Al2(SO4)3, we can calculate the moles of Al3+ as follows:

Moles of Al3+ = 0.42 mol Al2(SO4)3 x (2 mol Al3+ / 1 mol Al2(SO4)3)

Moles of Al3+ = 0.42 mol Al2(SO4)3 x 2

Moles of Al3+ = 0.84 mol Al3+

Therefore, there are 0.84 moles of aluminum ions (Al3+) present in 0.42 mol of Al2(SO4)3.

It's important to note that the stoichiometry of the compound determines the mole ratio between the different species involved in the chemical formula. In this case, the 2:1 ratio of Al3+ to Al2(SO4)3 allows us to determine the number of moles of Al3+ based on the given amount of Al2(SO4)3.

Answer:

The value of x in the hydrocarbon formula CxHy is 1.

Explanation:

Here's how to arrive at the solution:

Since the relative atomic mass of carbon is 12 and the hydrocarbon contains 9g of carbon, we know that there are 9/12 = 0.75 moles of carbon in the hydrocarbon.

Since the hydrocarbon only contains hydrogen and carbon, the remaining mass (12g - 9g = 3g) must be due to hydrogen.

To find the number of moles of hydrogen, we need to convert the mass of hydrogen to moles. The relative atomic mass of hydrogen is 1, so the number of moles of hydrogen is 3/1 = 3 moles.

Therefore, the ratio of carbon to hydrogen in the hydrocarbon is 0.75 moles of carbon to 3 moles of hydrogen, which simplifies to 1:4.

The general formula for the hydrocarbon can be written as CxHy. Since the ratio of carbon to hydrogen is 1:4, we know that x = 1 and y = 4. Thanks.
