Answer: C. a compound in which one or more carbon atoms have double or triple bonds.

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which single bond is present between C-C atoms. The general formula used for these hydrocarbons is  C_nH_{2n+2}. Example: CH_4

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent bonds present between carbon and carbon atoms. They are known as alkenes and alkynes respectively. The general formula used for these hydrocarbons is C_nH_{2n} and C_nH_{2n-2} respectively. Example: CH_2=CH_2

Both the hydrocarbons are not soluble in water as they are non polar in nature unlike water which is polar.

Cycloalkanes are also saturated hydrocarbons as single bond is present between C-C atoms.

Thus the correct statement is An unsaturated hydrocarbon is a compound in which one or more carbon atoms have double or triple bonds.

The mass of a substance is 27.46 g and its volume is 3.42 mL. What is the density of the substance? (hint: density = mass ÷ volu
marin [14]

Answer:

<h2>8.03 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{27.46}{3.42}  \\  = 8.029239

We have the final answer

<h3>8.03 g/mL</h3>

Hope this helps you

Which of the following will produce a precipitate?
Marta_Voda [28]

The correct answer is: c) Co2+(aq) + Zn(NO3)2 (aq)

Precipitation reaction can be defined as the process of the formation of an insoluble salt. An insoluble salt is formed when two solutions containing soluble salts are combined (from its aqueous ions). precipitation reaction refers to the. The insoluble salt that falls out of solution is called precipitate

A titanium cube contains 2.86×1023 atoms. what is the edge length l of the cube? the density of titanium is 4.50 g/cm3 . (the vo
IRISSAK [1]
When mass  Ti = density * volume 

and when moles Ti = mass Ti/molar mass Ti

                                 

∴ Volume = 2.86 x 10^23 atom * ( 1 mol Ti / 6.022 x 10^23) * (47.867 g Ti / 1 mol Ti) *(1Cm3 / 4.5 g Ti )

                = 5.05 Cm^3

when we assume that the sample of Ti is a cube:

and we assume the length = X

∴ V = X^3

∴X^3 = 5.05 

∴X = ∛5.05

     = 1.7 Cm

For each molecule of glucose processed during glycolysis, the net yield is ____. 1. two molecules of NADH, two of ATP, and two o
Lana71 [14]

Answer: 1. two molecules of NADH, two of ATP, and two of pyruvate

Explanation:

During glycolysis 4 molecules of ATP are synthesized by two substrate level phosphorylation (first in step 6 conversion of 1,3-Bisphospho glycerate to 3-Bisphospho glycerate by 1,3-Bisphospho glycerate kinase produces 2 molecules of ATP . Secondly 2 molecules of ATP is produced in step 9 by pyruvate kinase). But 2 molecules of ATP are used in step 1 and 3 by hexokinase and phospho fructo kinase respectively, hence a net yield of only two ATP.

2 molecules of NADH is produced in step 5 by Glyceraldehyde-3-phosphate dehydrogenase.

The end product of glycolysis is 2 molecules of pyruvate.
