Answer:
The volume of the gas at 100°C is 4.6189 liters.
Explanation:
For this problem we are going to use Charles' law. Charles' law states that the volume is directly proportional to temperature given that the pressure is constant. In order to use the equation, the unit of temperature should be in Kelvin.
The working equation is:
=
where V1 and T1 are the initial volume and temperature while V2 and T2 are the final conditions.
Let us convert first the temperatures before solving for the final volume.
To convert Celsius to Kelvin just add 273.15 to temperature in Celsius.
50°C + 273.15 = 323.15 K
100°C + 273.15 = 373.15 K
Solving for the final volume:
V₂ =
V₂ =
V₂ = 4.6189 L
Therefore the final volume of the gas at 100°C is 4.6189 L.

When in history was the origin of Sci-Fi as
genre?
Why then?
Answer:
The term science fiction was popularized, if not invented, in the 1920s by one of the genre's principal advocates, the American publisher Hugo Gernsback. The Hugo Awards, given annually since 1953 by the World Science Fiction Society, are named after him.

What controls the DNA molecule?
Answer:
nucleotides
Explanation:
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. ... DNA is made of chemical building blocks called nucleotides.

Provide one example where a neutralization reaction is undesired/harmful. State the reactants and explain why it is harmful for this reaction to take place.
Answer:
You're in my science class wth
Explanation:
For instance farmers are using basic fertilizers to neutralize an acid soil –which is harmful for the plants- while basic solutions are added in the chimneys of factories to neutralize the acid smoke that they produce –avoiding the catastrophic effects of the acid rains. Acid released in the environment from industry creates acid rain which has many ecological effects. Acid rain makes waters acidic, and causes them to absorb the aluminium that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

Where does much of our history of Precambrian rocks come from? fossils on the rock surface ores mined from shields ash taken from volcanoes trenches on the sea floor
Answer:
Ores mined from shields.
Explanation:
Ores mined from shields are the source from which we get the history of Precambrian rocks. The Ores from shield experience the Precambrian era so that's why its rocks provides information about that era. The Precambrian supereon is the division of the geological time scale which is the first and longest stage in the history of the Earth which also includes the Hádic, Archaic and Proterozoic eons.
how many moles of ions is in Magnesium chloride?
When 35.47 g of sodium hydroxide react with boric acid (H3BO3), how many moles of sodium borate will be produced?
Answer:
5.83 g
Explanation:
First, you must start with a balanced equation so you can see the mole ratios.
NaOH + H₃BO₃ --> NaBO₂ + 2H₂O
You can see that it takes 1 mole of sodium hydroxide to form 1 mole of sodium borate. 1:1 ratio
Now you must calculate how many moles of NaOH 35.47 g equals.
Na = 22.99 amu
O = 15.99 amu
H = 1.008 amu
NaOH = 39.997 amu
35.47 g ÷ 39.997 amu = 0.08868 moles of NaOH
Since it's a 1:1 ratio, the same number of moles of NaBO₂ is created. Now you must convert moles to grams.
Na = 22.9 amu
B = 10.81 amu
2 O = 31.998 amu
NaBO₂ = 65.798 amu
0.08868 moles x 65.798 = 5.83 g
A mixture of oxygen( O2), dinitrogen monoxide (N2O), and argon (Ar) has a total pressure of 0.98 atm. What is the partial pressure of N2O, if the partial pressure of O2 is 0.48 atm and the partial pressure of Ar is 0.15 atm?
Answer: The partial pressure of [tex]N_{2}O[/tex] is 0.35 atm.
Explanation:
Given: Total pressure = 0.98 atm
Partial pressure of [tex]O_{2}[/tex] = 0.48 atm
Partial pressure of Ar = 0.15 atm
Partial pressure of [tex]N_{2}O[/tex] = ?
Total pressure is the sum of partial pressure of each component present in a mixture of gases.
Hence, partial pressure of [tex]N_{2}O[/tex] is calculated as follows.
Total pressure = [tex]P_{N_{2}O} + P_{O_{2}} + P_{Ar}[/tex]
Substitute the values into above formula as follows.
[tex]Total pressure = P_{N_{2}O} + P_{O_{2}} + P_{Ar}\\0.98 atm = P_{N_{2}O} + 0.48 atm + 0.15 atm\\P_{N_{2}O} = 0.35 atm[/tex]
Thus, we can conclude that the partial pressure of [tex]N_{2}O[/tex] is 0.35 atm.

The piston of an internal combustion engine
compresses 218 mL of gas. The final pressure
is 15 times greater than the initial pressure.
What is the final volume of the gas, assuming
constant temperature?
Answer in units of mL.
Answer:
14.53ML
Explanation:
V1=218
V2=?
P2=15p1
USING BOYLE'S LAW
P1V1=P2V2
V2=P1V1/P2=P1(218ML)/15P1
=14.53ML
