Answer:
0, 1, 2
Explanation:
The rules for quantum numbers are:
n = 1, 2, 3, 4, …
l = 0, 1, 2, …, n - 1
mₗ = -l, -l + 1, …, 0, …, l - 1, l
If n = 3, l can go from 0 to 3 - 1 = 2.
The correct possible values of l are 0, 1, 2.
B is wrong because the maximum possible value of l is 2.
C and D are wrong because they contain negative numbers. They must be possible sets of magnetic quantum numbers, mₗ.
Answer:
A. 0,1,2
Explanation:
Which lifestyle is most likely to lead to infertility in a male ?
A man who works as a mechanic
A man who works as a computer programmer and sits at desk magority of the day
A semi professional athlete
A man who works for a company’s that applies pesticides to lawns
Answer:
The second on, A man who works as a computer programmer and sits at desk magority of the day.
Explanation:
Answer:
Explanation:
The only answer I can think as being possible is the last one. Pesticides are chemicals that go after unwanted animal life. They do not know that they should not attack human beings.
Infertility could very well be one of the side effects of a pesticide. There are others as well. Some pesticides go after the central nervous system (think mice and rats) and those are dangerous to use and to leave around.
The others all involve occupations that either require authentic abilities or mental astuteness. Neither should affect a man's ability to reproduce.
procedure to find out if the penny is real copper with copper wire
Answer:
Four ways to test a copper penny are given below:-
Explanation:
Firstly, take a quick look only at the color of the penny. Zinc pennies may appear patchy, irregular whereas copper-gold coins may seem more probable to be orange or even chocolate. Secondly, drop your penny on the floor and hear the noise it's making. The copper penny would have a "started to ring" sound in this situation, whereas the zinc penny should "clunk." Third, you can weigh the centimeter. You'll need an accurate scale weighing in grams. The penny of copper will weigh 3.11 grams while the penny of zinc weighs 2.5 grams. In the end, look at the date. If your penny was taken out of circulation before 1982, 95 percent copper and 5 percent zinc will be made. Beginning in 1982, pennies had just 2.5 percent copper and 97.5 percent zinc in them. Pennies from any of the two formulations made in 1982 may be produced.
The correct name for molecule I is
Molecule I
I
|
CH3-CH-CH3
a. Iodopropane
b. 2-iodylpropane
c. 2-iodopropane
D. Propyliodine
14. The correct name for molecule III is
Molecule III
F
|
C= CH
——-
a. 2-Fluoroeth 1-yne
b. Fluoroethyne
C. Fluoroethene
D. Methylfluorine
16. Synthetic chlorinated hydrocarbons such as dioxins and furans are usually greater pollution hazard then natural organic substances because synthetic hydrocarbons are
a. More volatile
b. Less water soluble
C. Less Biodegradable
D. More chemically reactive
Question 17.
Sources of pollutants
1. High temperature combustion
2. Pulp and paper industry
3. Pesticides
4. Sour gas plants
Match each source of pollutant as numbered above with its pollutant as listed below. Use each number only once
17. Dioxins/furans
18. SO2(g)
19. Nox(g)
20. Phosphates
Answer:
c). 2-iodopropane
14) C). Fluoroethene
16) D). More chemically reactive
17) 1). High temperature combustion - Dioxins/furans
2). Pulp and paper industry - SO2(g)
3). Pesticides - Phosphates
4). Sour gas plants - Nox(g)
Explanation:
The correct name for molecule I would be '2-iodopropane' where the number 2 reflects the position of iodine. There are three carbons and 8 hydrogen atoms which reflect that it is an alkane compound. In the given carbon chain. In this chain of three carbons, iodine is present on the second carbon. Therefore, option C is the correct answer.
14). The appropriate name for molecule III exemplifies Fluoroethene as it consists of two carbons due to which it belongs to the 'ethane' group and it bears the prefix 'fluoro as it belongs to fluorine group and the suffix '-ene' due to double bond.
16). Synthetic hydrocarbons are 'more chemically reactive' and therefore, it generates greenhouse gases and leads to climate change, global warming, depletion of the ozone layer, etc.
17). 1). Dioxins are generated as a result of high-temperature combustion processes like commercial waste incineration or burning of fuels.
2). Pulp and paper industry releases various gases like nitrogen oxide, sulfur dioxide SO2(g), carbon dioxide, etc.
3). Phosphate is the pollutant released from pesticides that badly affects the fertility of the soil.
4). Nox(g) nitrogen oxide released by sour gas plants and coal-fired emissions is a major contributor to increased greenhouses gases and global warming.
How many Liters of 18 M H2SO4 are needed to make 0.5 L of 1.5 M H2SO4
Answer:
0.04 L
Explanation:
The following data were obtained from the question:
Concentration of stock solution (C1) = 18M
Volume of stock solution needed (V1) =?
Concentration of diluted solution (C2) = 1.5M
Volume of diluted solution (V2) = 0.5L
The volume of the stock solution needed can be obtain by using the dilution formula.
This is illustrated below:
C1V1 = C2V2
18 x V1 = 1.5 x 0.5
Divide both side by 18
V1 = (1.5 x 0.5)/18
V1 = 0.04L
Therefore, the volume of the stock solution needed is 0.04L.
