Answer:

The correct answer is (C)

Which is "1-fluorobutane"

Explanation:

Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)

The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.

In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.

Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.

Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

Answer:

The hair color of a person

Explanation:

The correct answer would be the hair color of a person.

Qualitative data are data that cannot be measured with any instrument but can only be used to characterize. Unlike quantitative data, these kinds of data can only be observed and recorded but cannot be assigned numerical values, except if coded.

The sound of a person's voice can be quantitative on one hand and qualitative on the other. The intensity of a sound can be measured using a decibel meter and quantitatively assigned a figure, whereas, the quality of the sound can only be characterized and not measured.

Both the weight and the body temperature of a person can be measured using a weighing balance and a thermometer respectively and hence, are considered to be quantitative data when collected.

The color of the hair of a person cannot be measured but can only be observed and characterized. Hence, hair color data constitute qualitative data.

True. All metals have a melting point when it reaches a certain degree of temperature

Explanation:

Answer:

When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” Mono-” indicates one, “Di-” indicates two, “Tri-” is three, “Tetra-” is four, “Penta-” is five, and “Hexa-” is six, “Hepta-” is seven, “Octo-” is eight, “Nona-” is nine, and “Deca-” is ten.

The new  concentration = 2 M

Dilution is a process of decreasing the concentration of a solution by adding a number of solvents

Can be formulated

M₁V₁=M₂V₂

M₁ = Initial Molarity

V₁ = Initial volume

M₂ = Final Molarity (after dilution)

V₂ = Final volume (after dilution)

V₁=5 L

V₂=10 L

M₁=4 M

The new  concentration(M₂) :

[tex]\tt M_2=\dfrac{V_1.M_1}{V_2}\\\\M_2=\dfrac{5\times 4}{10}\\\\M_2=2~M[/tex]

Answer:

0.75 mol

Explanation:

Given data:

Number of moles of Na = 0.75 mol

Mass of water = 500 g

Moles of hydrogen gas produced = ?

Solution:

Chemical equation:

Na + H₂O   →      NaO + H₂

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 500 g/ 18 g/mol

Number of moles = 27.8 mol

now we will compare the moles of hydrogen gas with both reactant.

                   Na         :          H₂

                    1            :          1

                  0.75       :         0.75

                 H₂O        :          H₂

                   1            :           1

               27.8          :         27.8

sodium will act as limiting reactant it produced small number of moles of hydrogen gas as compared to water.

Thus, number of moles of hydrogen gas are 0.75 mol.

The dilution factor : 100

The dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution

From equation of dilution :

M₁V₁=M₂V₂

[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]

Volume of aliquot = 0.1 ml

Volume of diluent = 9.9 ml

So final volume :

Answer:

86

Explanation:

The reaction that takes place is:

First we convert moles of ethanol to moles of water:

Then we convert moles of water to grams of water, using its molar mass:

So 84.6 grams of water will be produced.

The mass of water, H₂O produced when 1.6 moles of ethanol, C₂H₅OH are completely burned is 86.4 g

We'll begin by writing the balanced equation for the reaction. This is given below

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

Therefore,

1.6 moles of C₂H₅OH will react to produce = 1.6 × 3 = 4.8 moles of H₂O.

Mole of H₂O = 4.8 moles

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass = mole × molar mass

Mass of H₂O = 4.8 × 18

Thus, the mass of water obtained from the reaction is 86.4 g
