A gas at a pressure of 608 mmHg is held in a container with a volume of 545 mL. What is
the volume at standard pressure?
Answer:
441.81 mL
Explanation:
P1 x V1 = P2 x V2
V2 = P1 x V1 / P2
V2 = 608 x 545 / 750
V2 = 331360 / 750
V2 = 441.81 mL

If anyone has even one answer to any of these, that'd be really helpful!! Thank you! ^^
The appearance of ions in solution makes a solution to conduct electricity.
What is conductivity?Conductivity refers to the flow of current through a solution.
1) There is an evidence that reaction has occurred because of the formation of a precipitate
2) The conductivity decreases as more H2SO4 was added.
3) The indicator of the number of ions in the solution is the current recorded.
4) This evidence indicates that a reaction has occurred because the formation of a precipitate decreases the current.
5) Ba(OH)2(s) ----> Ba^2+(aq) + 3OH^-(aq)
H2SO4(aq) ---> 2H^+(aq) + SO4^2-(aq)
6) When the conductivity is at the minimum, It means that the Ba(OH)2 is largely undissociated.
7) It does not conduct at a low point because there are no ions in solution.
8) It conducts more before and after this minimum point because of more ions in solution.

Measurement units are the defined units used for the particular dimensions and proportions. 3500 milliseconds are there in seconds.
What is the unit of time?Time is defined as the rate of things occurring or taking place and is given by seconds, minutes, hours etc.
Using the conversion factor the relation between the seconds and milliseconds is:
1 second = 1000 miliseconds
Convert 3.5 seconds into milliseconds using conversion factor:
[tex]\begin{aligned}3.5 \;\rm seconds &= 3.5 \times 1000 \\\\&= 3500 \;\rm miliseconds\end{aligned}[/tex]

14. A 500.0 ml flask contained O2 gas at 25.0°C at a pressure of 4.5 atm. What is the number
of moles in the flask?
Explanation:
3.Apply the ideal gas law: PV = nRT solving for n. Here you can use the pressure given in atm, but you must choose the 0.0821 atm L/mole K gas constant. Or you can change 4.5 atm to 3420 mm Hg and use the 62.4 mmHg L/mole K gas constant. You must change 500 ml to 0.5 L because both gas constants have units in L, and so the volume must be in liters so it can cancel out. And of course, you must change the temperature to Kelvin.
a. n = (4.5atm)(0.5L)
moliK)(298K) = 0.092 mole (0.0821 atmiL
b. 0.092mol 32g
⎛⎝⎜ ⎞⎠⎟ = 2.9 g

c. Remember that D = mass
vol so D = 2.9g

please help 500 J of work are done on a box when it is pulled horizontally across a frictionless floor by a force of 50 N. How far did the box slide?
A. 15 m
B. 1 m
C. 10 m
D. 100 m
Answer:
C: 10m
Explanation:
Work Done = Force x Distance
500 = 50 x Distance
To get to 500 multiply 50 by 10!
So, the box slid 10m.

1. State the law of Conservation of linear momentum.
2. Explain why momentum must be conserved in an isolated system.
Answer:
Law of conservation of linear momentum :- when there is no any external force applied on a system of particles then , momentum of system of particles will be conserved or you can say that if external force is zero. Then momentum of system of particles in intially = momentum of system of particles in finally
Explanation:
According to Newton's second law of motion, because no external force occurs on the system, The change in momentum is equal to zero; hence, the linear momentum is conserved. The entire linear momentum of an isolated system, that is, a system that is not subjected to any external forces, is conserved.
1. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.
2. It must be conserved in an isolated system because isolated systems do NOT exchange matter or energy with their surroundings.
How many compounds are found in 2.3 moles of Ca(NO3)2?
Answer:
For every 1 Ca(NO3)2 there are six (2 * NO3 or 2 * 3 O) oxygens. If you have 3 mole of Ca(NO3)2 then you have 18 mole of oxygen atoms (3*6).
Explanation:
If 4.644.64 mol of NO2NO2 occupy 25.925.9 L, how many liters will 2.732.73 mol of NO2NO2 occupy at the same temperature and pressure
Answer:
I will assume that the moles are all mistyped and will change them to:
4.64, 25.9, and 2.73.
15.2 liters
Explanation:
Both situations can be described using the ideal gas law:
PV=nRT,
where P, V, and T are the pressure, volume, and temperature (in degrees K). n is the number of moles. R is the gas constant.
First NO2 : P1(25.9L) = (4.64moles)RT
Second NO2: P2V2 = (2.73moles)RT2
Divide one equation by the other:
(P1(25.9L) = (4.64)RT1)
P2V2 = (2.73)RT2
The temperatures, pressures, and gas constants are unchanged, so we can cancel those to obtain:
(25.9L)/V2 = (4.64/2.73)
V2 = (25.9L)(2.73/4.64)
V2 = 15.2 Liters
