How many grams of carbon dioxide (CO2) are found in a 11.9 L container under 1.5 atm and 20.0oC.

Answers

Answer 1

Answer: pV=nRT

p = 1,5atm = 1,5*101325 = 151987,5 Pa
V = 11,9l = 0,0119m3
n = ?
R = 8,314 J/mol*K
T = 20°C = 20+273 = 293K

pV=nRT
151987,5*0,0119 = n*8,314*293
1808,6513=n*2436,002 ||:2436,002
0,7425 = n >>> moles of CO2

1 mole of CO2 = 44g

1 mole of CO2--------------44g
0,7425 moles of CO2----------x
x = 32,67g of CO2

Which statement correctly compares an atom of an alkali metal with an atom of the alkaline earth metal next to it on the periodic table?The alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.
The alkali metal atom forms a +2 ion, while the alkaline earth metal atom forms a +1 ion.
The alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal.
The alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.

Answers

Answer: The alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.

Explanation: Group 1 elements are called as alkali metals and group 2 elements are called as alkaline earth metals.

For example, Li is an alkali metal and Be is an alkaline earth metal.

Lithium(Li) has an atomic number of 3 and the electronic configuration is:

Li: $1s^22s^1$

Thus lithium has to lose 1 electron and acquire 1+ charge to attain nearest noble gas configuration.

$Li^+:1s^2$

Berrylium(Be) has an atomic number of 4 and the electronic configuration is:

Be: $1s^22s^2$

Thus berrylium has to lose 2 electrons and acquire 2+ charge to attain nearest noble gas configuration.

$Be^(2+):1s^2$

If 2.0 mL of 6.0M HCl is used to make a 500.0-mL aqueous solution, what is the molarity?

Answers

Answer:

0.024M

Explanation:

Data obtained from the question include:

C1 = 6M

V1 = 2mL

C2 =?

V2 = 500mL

The molarity of the diluted solution can be obtained as follows:

C1V1 = C2V2

6 x 2 = C2 x 500

Divide both side by 500

C2 = (6 x 2) /500

C2 = 0.024M

The molarity of the diluted solution is 0.024M

Answer:

The molarity is 0.024 mol / L

Explanation:

Molarity = Number of moles / Volume of solution

= (6.0 mol/L x 2.0 x $10^(-3)$ L) / 0.500 L

= 0.024 mol / L

Which ion was formed by providing the second ionization energy to remove an electron?

Answers

The correct answer for the question above is S2- (Sulfide.) S2- ion was formed by providing the second ionization energy to remove an electron. S2- is actually an inorganic anion of Sulfur. This anion contributes no color to any objects and is classified as a strong base.

Answer: Since most of the dissolved CO2remains as CO2 molecules, Ka1(apparent) has a much larger denominator and a much smaller value than the true Ka1. The bicarbonate ion is an amphoteric species that can act as an acid or as a base, depending on pH of the solution. At high pH, it dissociates significantly into the carbonate ion (CO2−3):

Explanation: In organisms carbonic acid production is catalysed by the enzyme, carbonic anhydrase. CO2 is a potent electrophile having an electrophilic reactivity that is comparable to benzaldehyde or string α,β-unsaturated carbonyl compounds. However, unlike electrophiles of similar reactivity, the reactions of nucleophiles with CO2 are thermodynamically less favored and are often found to be highly reversible. Only very strong nucleophiles, like the carbanions provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates. In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals. The reduction of CO2 to CO is ordinarily a difficult and slow reaction:

When the pH of a solution changes from a pH of 5 to a pH of 3, the hydronium ion concentration isA. 0.01 of the original content
B. 0.1 of the original content
C. 10 times the original content
D. 100 times the original content

Answers

Answer : The correct option is, (D) 100 times the original content.

Explanation :

As we are given the pH of the solution change. Now we have to calculate the ratio of the hydronium ion concentration at pH = 5 and pH = 3

As we know that,

$pH=-\log [H_3O^+]$

The hydronium ion concentration at pH = 5.

$5=-\log [H_3O^+]$

$[H_3O^+]=1* 10^(-5)M$ ..............(1)

The hydronium ion concentration at pH = 3.

$3=-\log [H_3O^+]$

$[H_3O^+]=1* 10^(-3)M$ ................(2)

By dividing the equation 1 and 2 we get the ratio of the hydronium ion concentration.

$([H_3O^+]_(original))/([H_3O^+]_(final))=(1* 10^(-5))/(1* 10^(-3))=(1)/(100)$

$100* [H_3O^+]_(original)=[H_3O^+]_(final)$

From this we conclude that when the pH of a solution changes from a pH of 5 to a pH of 3, the hydronium ion concentration is 100 times the original content.

Hence, the correct option is, (D) 100 times the original content.

pH = -log( [H3O+] )
so the pH is in powers of 10
1* 10^ 5 / 1*10^3 = 1* 10^2 = 100
so the answer is:
D. 100 times the original content

]Astrology is a pseudoscience because

Answers

The word Pseudoscience really means that it's just a collection of beliefs or practices that are mistake or regarded as being scientific fact. Astrology is a belief system, while on the other hand, its brother, Astronomy is a science. These two go hand in hand. It's a quite common mistake to mix up Astrology (star signs) and Astronomy (study of space) . In order for a hypothesis to be scientific, it has to satisfy a certain criteria: it has to be a testable thing. So therefore Astrology is a business, so it can be skeptical. There is hard to get any proof that Astrology is really a pseudoscience. Sorry if I was not much help.... Hope it helped anyway.
