All three phases can exist in an equilibrium with one another at the __ of a substance

Chemistry
1 answer:
tensa zangetsu [6.8K]3 years ago
5 0

Answer:

Triple point

Explanation:

Yes, all three phases can exist in an equilibrium with one another at the triple point of a substance.

In thermodynamics, the triple point of a substance is defined as the point at which all three phases of substance co-exist together at a particular pressure and temperature.

for example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.

And for water it is 0.01 °C and 611.73 pascals.

you will get some clear idea after seeing the graph.

And critical point as you see in the graph is end point of phase equilibrium curve, mainly liquid-vapor equilibrium

Answer:

Multiply 1.25 by 0.04 and divide the result obtained by 1,000

Explanation:

Since there is .04 oz in 1 gram, we take the 1.25 gram and multiply by .04.

Next, to convert per liter to per milliliter, we divide by 1,000.

How many moles of propane gas would be present in 11 grams<br> of the gas at standard conditions?
Akimi4 [234]
The molar mass is usually referred to with
M
, while the mass is referred to as
m
. The amount of substance is
n
. This gives you the following relationship:
=
M
=
m
n

Since you have given (C3H8)=11 g
m
(
C
3
H
8
)
=
11

g
and you already looked up (C3H8)=44.1 gmol−1
M
(
C
3
H
8
)
=
44.1

g
m
o
l
−
1
, you can use this formula to determine (C3H8)
n
(
C
3
H
8
)
.

In this question it is quite hard to explain the use of significant figures. Those are used to imply a certain inaccuracy. Not enough information is given by the question, as of how accurate the measurement is. It is a mere exercise of converting one property into another. Here you should not worry about it.

What is absolute zero? A) The temperature at which the particles of matter are at their lowest energy points. B) The temperature
Alja [10]

Answer:

A) The temperature at which the particles of matter are at their lowest energy points.

Explanation:

Absolute temperature refers to the lowest  possible temperature. At this state,  no heat energy remains in the substance; the energy of the particles are at their lowest energy points.

Balance the following chemical equations:
tamaranim1 [39]

Answer:

Explanation

=============

One

=============

Ca(OH)2 + 2HNO3 -----> Ca(NO3)2 + H2O

Focus on the NO3. This is an odd problem and you usually do not focus on the complex ion. But this one works easiest if you do.

The problem now is going to be the oxygens. There are 2 with the Calcium and only 1 free one going to the water. (The NO3 has been taken care of in the last step).

Ca(OH)2 + 2HNO3 -----> Ca(NO3)2 + 2H2O

Count the atoms. I think this equation is balanced.

atom                      Left              Right         Result

Ca                            1                    1               Balanced

O                              8                   8              Balanced

H                              2 + 2              2*2         Balanced

N                               2                    2            Balanced

===========

Two

===========

CH4 + O2====>  CO2 + H2O

Start with the hydrogens.

The right side requires a 2

CH4 + O2 ===>  CO2 + 2H2O

Now look at the oxygens. There are 4 on the right. and only 2 on the left. You need to multiply O2 by 2

CH4 + 2O2 ===>  CO2 + 2H2O

Each side has 1 Carbon 4 hydrogens and 4 oxygens. The equation is balanced.
