When the temperature of a rigid hollow sphere containing 685 L of helium gas is held at 621 K, the pressure of the gas is 1.89 x

Leno4ka [110]

You have to use the equation PV=nRT.
P=pressure (in this case 1.89x10^3 kPa which equals 18.35677 atm)
1V=volume (in this case 685L)
n=moles (in this case the unknown)
R=gas constant (0.08206 (L atm)/(mol K))
T=temperature (in this case 621 K)
with the given information you can rewrite the ideal gas law equation as n=PV/RT.
n=(18.35677atm x 685L)/(0.08206atmL/molK x 621K)
n=246.8 moles

Who has taken chemistry, if you have I want to know how were you successful (if u were) because currently I am taking it and I’m

Andreas93 [3]

My number one tip is to STUDY! I know it sucks, but once you're in high school, it's going to become a part of your routine every single day. Even if you study right now, keep on doing it over and over and over. Trust me! It'll help. Also, get a tutor! Maybe someone you know is doing well and you could ask them to help, or you could ask a student who was in your class and passed. My number one advice is to just keep working hard. I get it; chemistry is HARD. You'll get there!

PLEASE URGENT I will give MOST POINTS POSSIBLE For the following reactions, (a) write the balanced reaction equations and (b) ID

Tema [17]

Answer:

see below

Explanation:

Aqueous hydroiodic acid reacts with liquid water in a reversible reaction.

2 HI + 2 H₂O ⇔ 2 H₃O + I₂

This is an acid-base reaction. HI is the acid, and H₂O is the base. The conjugate acid is H₃O, and the conjugate base is I₂. You can figure out the acid and base by a using a table of strong/weak acids and bases. The conjugate will have one less or one more H⁺ depending on if it's an acid or a base.

The expression for Kₐ of the reaction is below. You have to put the acid and its conjugate base on the top and the base and its conjugate on the bottom. I didn't put in H₂O since, although it is the base in this equation, it isn't really a base.

$K_{a}=\frac{[HI][H_{3}O] }{[I_{2}] }$

Solid zinc reacts with solid manganese (IV) oxide producing solid zinc oxide and solid manganese (III) oxide.

Zn + 2 MnO₂ ⇒ ZnO + Mn₂O₃

This is a redox reaction. The Zn is being oxidized, and the Mn is being reduced.

Oxidation: Zn ⇒ Zn⁺² + 2 e⁻

Reduction: Mn⁺⁴ + e⁻ ⇒ Mn⁺³

Aqueous silver nitrate reacts with aqueous calcium chloride.

2 AgNO₃ + CaCl₂ ⇒ 2 AgCl + Ca(NO₃)₂

This is a precipitation reaction. You have two soluble salts combing to form a solution. You now need to figure out which of the compounds produced are not soluble. AgCl is the compound that is not soluble in water, making it the precipitate.

I think I covered everything. If I missed something let me know.

In a solution of 77 percent nitrogen and 23 percent oxygen, which is the solvent?

drek231 [11]

I am pretty sure nitrogen would be the solvent because solvents are generally the larger amount
