Answer:

1-hexene. is your answer.

The name of the given alkene is Hex-1-ene

In order to name the given alkene, we will follow some of the IUPAC rules for naming alkenes. The rules are:

1. The longest chain chosen for the root name must include both carbon atoms of the double bond.

2.The root chain must be numbered from the end nearest a double bond carbon atom.

3. The smaller of the two numbers designating the carbon atoms of the double bond is used as the double bond locator.

The given alkene is

CH3CH2CH2CH2CH = CH2

The longest chain has 6 carbon atoms, which means it is a Hexene.

If numbered from the end nearest the double bond carbon atom, the double bond will be on carbon - 1

∴ Hex-1-ene

Hence, the name of the given alkene is Hex-1-ene

Answer:

Option B

The atmospheric pressure at sea level is higher.

Explanation:

Atmospheric pressure can simply be understood as the weight of the air molecules in the atmosphere. The higher we go up into the atmosphere, the thinner the air becomes. This means that the air present at higher heights is not so much, and hence, the air is lighter. This is why most fighter jets and mountain climbers need oxygen tanks to breathe properly.

Due to the fact that the air is less dense (lighter) at higher altitudes, it also means that the atmospheric pressure at higher altitudes is less.

Therefore, the atmospheric pressure at the sea level is higher than the atmospheric pressure at  altitudes above sea level

Answer:

B. The atmospheric pressure at sea level is higher.

Answer:1.4 g/L

Explanation:

One mole of very substance at STP contains a  volume of 22.4 liters. Density can be found by dividing the mass by volume . The density of the gas with a molecular mass of 32 grams is 1.42 g/l.

Density of a substance is the measure of its mass per volume. It represents how much denser it is in a given volume. Density depends on the molecular weight, bond type, volume, temperature and pressure.

STP is defined as the condition of standard temperature and pressure. 293 K and 1 atm pressure are considered to be the standard conditions. At STP, the volume of one mole of every substances contains 22.41 liters.

It is given that the molecular weight of the gas is 32 g/mol. Thus its density in one mole can be calculate as follows:

Density = mass/ volume.

             = 32 g/ 22.4 L

             = 1.42 g/L.

Hence, the density of the gas at STP with molecular mass of 32 g is 1.42 g/L.

Answer:

32.3%

Explanation:

Percent yield is defined as:

Actual yield (125.5g) / Theoretical Yield * 100

To find theoretical yield we have to find the moles of aluminium. As 2 moles of Al produce 2 moles of AlCl3, the moles of Al = Moles AlCl3.

With these moles we can find the mass assuming a 100% of yield (Theoretical Yield) as follows:

Moles Al = Moles AlCl3 (Molar mass Al = 26.98g/mol)

72g Al * (1mol / 26.98g) = 2.67 moles AlCl3

Mass AlCl3 (Molar mass: 133.34g/mol)

2.67 moles AlCl3 * (133.34g / mol) = 355.8g AlCl3

Percent Yield = 125.5g / 355.8g * 100 =

the closest value is C, 85.

hope it helps!!!!

85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population. Therefore, the correct option is option C.

A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people where a statistical sample has been collected in statistics. Hence, a population is any collection of people who have something in common.

A statistically substantial chunk of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, meaning standard error, of a statistical study of a sample from the full population must be disclosed. Only a population-wide analysis would have zero standard deviation. 85 is the estimate value that is obtained from a sample of which size is likely to be closest to the actual parameter value of a population.

Therefore, the correct option is option C.

Answer:

d Theoretical yield

Explanation:

I took the test :)

Theoretical yield term is used to describe the maximum amount of a product that can be produced by a given amount of reactant

The theoretical yield is just the maximum mass of a product that a chemical reaction can produce.

Theoretical yield the amount of product produced by a perfect (theoretical) chemical reaction, not the amount that will receive from a laboratory reaction. The balanced chemical equation can be used to calculate theoretical yield, the limiting reactant's mass and relative formula mass, as well as the product's relative formula mass.

Answer:

2.0x10¹⁷ Hz is the frequency of the X-ray

Explanation:

We can find the frequency of a wave of energy from the wavelenght and its speed using the formula:

v = λƒ

Where v is speed (For electromagnetic radiation = 3.0x10⁸m/s)

λ is the wavelength in meters = 1.5x10⁻⁹m

And f is the frequency in s⁻¹ = Hz

Replacing:

3.0x10⁸m/s = 1.5x10⁻⁹m*ƒ

3.0x10⁸m/s / 1.5x10⁻⁹m = f

The scattering of the particles of the light in suspension and colloid is the Tyndall effect or scattering.

Colloidal and suspension are the types of solution that contains the mixture of the solute in the solvent. The colloidal solution includes the insoluble solute dispersed in the medium.

The light directed towards the colloidal solution gets scattered by the solute particles present in the solution and hence is used to prove true solutions apart from the colloidal and suspension.

Therefore, the Tyndall effect is the light scattering by colloidal solution.

Answer:

Final temperature of water = 31.2° C

Explanation:

Let the final temperature of water be T degrees

Concept: By energy conservation law

Heat lost by the silver = heat gained by water

Heat lost be silver Q1 = m1c1ΔT1

Q1 = 45.2/1000Kg×2.36J/KgK×(101-T)

Heat gained by water Q2 = m2c2ΔT2

Q2 = 300/1000Kg×4.186J/KgK(T-30.6)

Since, Q1=Q2

⇒  45.2/1000Kg×2.36J/KgK×(101-T) = 300/1000Kg×4.186J/KgK(T-30.6)

Solving we get T = 31.2° C

Therefore, final temperature of water = 31.2° C
