If 3.0 moles of a gas are in a 60.0 liters container at 400.0 K, what is the pressure, in atm, inside
the container?
A.
0.61 atm
B.
16 atm
C.
1.6 atm
Answer:
C. 1.6 atm
Explanation:
PV = nRT
Solve for P --> P = nRT/V
n = 3.0 mol
R = 0.08206 L atm / mol K
T = 400.0 K
V = 60.0 L
P = (3.0)(0.08206)(400.0) / (60.0) = 1.6 atm
Convert 812.4 kPa into atm
Answer:
Explanation:
There are a series of unit used to measure PRESSURE. They include millimetre mercury (mmHg), atmospheric pressure (atm), kilopascal etc. These units of measurement are interconvertible i.e. can be changed from one unit to another.
Based on this question asking to convert
1 kilopascal = 0.00986923atm
If you want to change the mass of your atom by 1 or more mass units, you can ether
(2 RIGHT CHOICES)
add a proton
add a neutron
add an electron
If you want to change the mass of your atom by 1 or more mass units, you can either? Add a proton and Add a neutron.
Explanation:
Option A and Option B is your answers.
To change the mass of your atom by more mass units ; you can add a proton or add a neutron ( A and B )
The nucleus of an atom is composed of a neutron and a proton while the outer shell of an atom comprises of the electrons.
The mass of an atom is dependent on the mass of the nucleus of the atom therefore to increase the mass of the atom by any number of mass units you can either add a proton or a neutron to the nucleus of the cell.
Hence we can conclude that to change the mass of your atom you can add a proton or add a neutron to the nucleus of the atom

how many moles of sodium phosphate are required to make 7.5 moles of sodium nitrate in 2Na3PO4+3Be(NO3)=6NanO3+Be3(PO4)2
Answer:
2.5 moles of sodium phosphate
Explanation:
3 Pb(NO3)2 + 2 Na3PO4 → Pb3(PO4)2 + 6 NaNO3
6 (moles in the reaction)- 7.5(moles in the task)
2 (moles in the reaction)- x (moles in answer) ⇒6x = 2*7.5 ⇒ x = 15/6=2.5 (moles)
A slug travels the length of a log in 2 hours. If the slug's average speed is 1.5 cm / minute how long is the log
Answer:
The length of the log is 180 cm
Explanation:
From the question given above, the following data were obtained:
Time = 2 hours
Speed = 1.5 cm/min
Distance =?
Next, we shall convert 2 hours to minutes. This can be obtained as follow:
1 h = 60 mins
Therefore,
2 h = 2 × 60
2 h = 120 mins
Finally, we shall determine the Lenght of the log. This can be obtained as follow:
Time = 120 mins
Speed = 1.5 cm/min
Distance =?
Speed = distance / time
15 = distance / 120
Cross multiply
Distance = 1.5 × 120
Distance = 180 cm
Therefore, the length of the log is 180 cm
Answer:
180
Explanation:
The mass of this atom is:
u. 3 mass units
b. 4 mass units
c. 6 mass units
d. 7 mass units

El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.
Answer:
La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad
Explanation:
El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.
How many meters are in 65 millimeters?

A bottle contains 2.5 moles of KOH dissolved in water, and the molarity of the solution is 0.16 M.
What volume of solution is in this bottle?
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:
[tex]M=n/V[/tex]
Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L
