What is alkene?Alkenes are a group of unsaturated hydrocarbons with at least one double bond between carbon atoms that are pure carbon and hydrogen based. Olefins is another name used to denote alkenes. The double bond in alkenes makes them more reactive than alkanes. A hydrocarbon with a carbon-carbon double bond is known as an alkene in organic chemistry. Any hydrocarbon with one or more double bonds is referred to as an alkene, which is frequently used as a synonym for an olefin. The distinction between internal and terminal monoalkenes is made in general.The 2-step elimination reaction, referred to as the E1 reaction, involves the creation of a carbocation as an intermediate step. The system expels a proton and a leaving group. In this instance, the rate is only influenced by the substrate. In compounds when more substituted alkenes are produced, the primary product will be taken into consideration.More +I impact will be visible from them as the number of substituted alkyl groups increases. The product generated becomes more stable as a result.As a result, the primary product generated in an E1 reaction is:To learn more about alkene refer to:

Use the Nernst equation to calculate the concentration of the unknown solution. Base this on your experimental voltage of 1.074 V for the galvanic cell with this unknown combined with your copper half-cell. Use the unrounded [Cu2+] value of .050179 M and the unrounded value of the constants as listed in the file link near the top of this assignment to avoid round-off error.
Answers
Answer:
0.3793 M
Explanation:
The unknown metal is zinc. So the equation of the reaction is;
Zn(s) + Cu^2+(aq) -------> Zn^2+(aq) + Cu(s)
From Nernst equation;
E = E° - 0.0592/n log Q
[Cu2+] = 0.050179 M
n = 2
[Zn^2+] = ?
E = 1.074 V
E° = 0.34 - (-0.76) = 1.1 V
Substituting values;
1.074 = 1.1 - 0.0592/2 log [Zn^2+]/0.050179
1.074 - 1.1 = - 0.0592/2 log [Zn^2+]/0.050179
-0.026 = -0.0296 log [Zn^2+]/0.050179
-0.026/-0.0296 = log [Zn^2+]/0.050179
0.8784 =log [Zn^2+]/0.050179
Antilog(0.8784) = [Zn^2+]/0.050179
7.558 = [Zn^2+]/0.050179
[Zn^2+] = 7.558 * 0.050179
[Zn^2+] = 0.3793 M
A sample of a compound was found that has 40.25g of (C) Carbon and 59.75g of (O) Oxygen.
What is the empirical formula for this sample.
Answers
Answer:
CO
Explanation:
From the question given above, the following data were obtained:
Mass of Carbon (C) = 40.25 g
Mass of oxygen (O) = 59.75 g
Empirical formula =?
The empirical formula of the compound can be obtained as follow:
C = 40.25 g
O = 59.75 g
Divide by their molar mass
C = 40.25 / 12 = 3.354
O = 59.75 / 16 = 3.734
Divide by the smallest
C = 3.354 / 3.354 = 1
O = 3.734 / 3.354 = 1
The empirical formula of the compound is CO

Given 5.86 grams of NaN3, how many grams of Na are produced?
Answers
Answer:
what no entiendo nada jahag6
When 5.86 grams of NaN3, then 22.99 gram of Na are produced by using mole formula.
What is gram ?A thousandth of a kilo-gram in terms of mass in the metric system.
What is mole?A mole is a unit of measurement for atom amount. A mole of Iron atoms weighs heavier than just a mole of Carbon molecules because it is measured by the number of atoms present instead of by weight.
The reaction can be written as:
[tex]2 Na N_{3}[/tex] → 2Na + [tex]3N_{3}[/tex].
It can be seen that 2 mole of sodium azide give 3 mole of nitrogen molecule.
Calculate the moles of Na.
Moles of Na = 1 mol sodium azide × 2 mol of Na / 2 mol sodium azide = 1 mole of Na.
Calculate the mass of Na.
Mass of Na = 1 mol Na × 22.99 g Na / 1 mol Na = 22.99 gNa.
Therefore, the mass of Na will be 22.99 gram

Answers
Answer:
What you need to know before I explain is how to add percents onto numbers. What I'm saying is what and how to do 6.4% x 1500
1. You can't do a percent and number together, that's impossible
What you can do is convert the percent (6.4%) into a decimal
2. 6.4% is equivalent to 6.4/100, which is equivalent to 0.064
3. Now, you multiply 0.064 x 1500
You will notice, hopefully, that you have a number smaller than 1500, but do not panic, you are on the right track!
4. Using the number you got, add that to 1500, and there's your total!
But, if you want only the tax, keep that small number you started off with!

What is the percentage by mass of chromium in sodium dichromate (VI) Na2
Cr2
O7
?
Answers
Answer:
39.7%
Explanation:
To obtain the percentage composition of chromium (Cr) in Na₂Cr₂O₇, do the following:
Molar mass of Na₂Cr₂O₇ = (23×2) + (52×2) + (16×7)
= 46 + 104 + 112
= 262 g/mol
Mass of Cr in Na₂Cr₂O₇ = 2 × 52 = 104 g
Percentage composition of Cr = mass of Cr / Molar mass of Na₂Cr₂O₇ × 100
= 104 / 262 × 100
= 39.7%
Thus, the percentage composition of chromium (Cr) in Na₂Cr₂O₇ is 39.7%
Charcoal from the dwelling level of the Lascaux Cave in France gives an average count of 0.97 disintegrations of C-14 per minute per gram of sample. Living wood gives 6.68 disintegrations per minute per gram. Estimate the date of occupation and hence the probable date of the wall painting in the Lascaux Cave. (Half-life of C-14 is 5568 years)
Answers
Answer:
15502 years
Explanation:
From;
0.693/t1/2 = 2.303/t log [Ao]/[A]
Where;
t1/2 = half life of C-14
t = time taken
[Ao] = count rate of living sample
[A] = count rate of the charcoal under study.
0.693/5568 = 2.303/t log (6.68/ 0.97)
1.245 * 10^-4 = 2.303/t log (6.887)
1.245 * 10^-4 = 1.92998/t
t = 1.92998/1.245 * 10^-4
t = 15502 years

Given : 1 mole molecule of water contains 6.023*10^23 molecules of water.
6.023*10^23 molecules are present in = 1 mole
8.30*10^23molecules will be present in =

An unknown hydrocarbon reacts with oxygen to produce carbon dioxide and water. The number of oxygen molecules in the reactants is the same as the number of hydrocarbon molecules. What are the two possibilities for the molecular formula of the hydrocarbon?
Answers
Explanation:
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. They are most famous for being the primary constituent of fossil fuels, namely natural gas, petroleum, and coal. For this reason, fossil fuel resources are often referred to as hydrocarbon resources.[1] Energy is obtained from fossil fuels through combustion (burning) of the fuel. Although impurities exist in fossil fuels, hydrocarbon combustion is the primary process in the burning of fossil fuel.

A combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Heptane is a hydrocarbon that is found in gasoline. Complete combustion of heptane produces 7 liters of carbon dioxide for every 8 liters of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of heptane
Answers
Answer:
7/16
Explanation:
The general formula for the combustion of alkanes is;
CnH2n+2 + 3n+1/2 O2 -------> nCO2 + (n+1)H2O
So, we have;
CnHn + nO2 ------> 7CO2 + 8H2O
So there are 7 carbon atoms and 16 hydrogen atoms in heptane according to the law of conservation of mass.
Therefore, heptane is; C7H16
The ratio of carbon to hydrogen is now; 7/16
