Answer:
The volume of the dry gas at STP is = 0.4314 L
Explanation:
We are given:
Total vapor pressure = 740 mmHg
Also, considering Vapor pressure of water = 23.78 mmHg
Vapor pressure of gas = Total vapor pressure - Vapor pressure of water = (740 - 23.78) mmHg = 716.22 mmHg
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 716.22 mmHg
V = Volume of the gas = 500 mL = 0.5 L ( 1 ml = 0.001 L )
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = ?
Putting values in above equation, we get:
At STP, 1 mole of gas yields a volume of 22.4 L
So,
0.01926 mole of gas yields volume of
<u>Hence, the volume of the dry gas at STP is = 0.4314 L</u>
Answer:
The products are SnPO4 and LiC2H3O2
Explanation:
The reactants are LiPO4 + Sn(C2H3O2)2
This is a double replacement reaction
So what you do is switch the elements the other way around.
To do that, all you have to do switch Sn with PO4 since Sn is a cation and PO4 is an anion.
Then you switch Li with C2H3O2 because Li is a cation and C2H3O2 is an anion.
After that, check the charges. PO4 has -3 charge
So just leave Sn the way it is without a subscript.
In word form, the product would be Tin(III) Phosphate
C2H3O2 has a -1 charge Li has a +1 charge
So leave both of them the way it is without any subscripts.
In word form, the product would be Lithium Acetate
Answer:
The Columbus Day Storm of 1962 (also known as the Big Blow,[2] and originally as Typhoon Freda) was a Pacific Northwest windstorm that struck the West Coast of Canada and the Pacific Northwest coast of the United States on October 12, 1962. It is considered the benchmark of extratropical wind storms. The storm ranks among the most intense to strike the region since at least 1948, likely since the January 9, 1880 "Great Gale" and snowstorm. The storm is a contender for the title of most powerful extratropical cyclone recorded in the U.S. in the 20th century; with respect to wind velocity, it is unmatched by the March 1993 "Storm of the Century" and the "1991 Halloween Nor'easter" ("The Perfect Storm"). The system brought strong winds to the Pacific Northwest and southwest Canada, and was linked to 46 fatalities in the northwest and Northern California resulting from heavy rains and mudslides.
Explanation:
Answer:
Isotopes are given by the name of the element and the mass number. ... We are given that boron-10 had five protons in its nucleus, and any element always has the same number of protons in its nucleus (atomic number). So boron-11 has five protons the same as boron-10
AgNO₃ + NaCl = NaNO₃ + AgCl↓
c(AgNO₃)=0.04 mol/L
c(NaCl)=0.002 mol/L ⇒ n(AgCl)/L=0.002 mol/L
Ksp=[Ag⁺][Cl⁻]
the solubility of silver chloride
√Ksp=1.34*10⁻⁵ mol/L
n(AgCl)/L>√Ksp the precipitate of silver chloride is formed
