Answer:
2-propanol
Explanation:
From the given information
2 drops of an unknown sample were said to be placed in a test tube followed by the addition of 2 ml of ethanol then gentle mixing. They then initiate a further addition of 2 drops of potassium permanganate reagent (KMNO₄) to the test tube and mixed the contents of the test tube thoroughly. After adding 2 drops of potassium permanganate reagent, the reagent oxidizes the secondary alcohols(2-propanol) to ketone(i.e acetone) and no further reaction will take place since there are no reactive C-H bonds left. The diagram attached below shows how the reaction proceeds.
Answer:
2.355atm
Explanation:
To get the pressure of helium, we need to get the mole fraction of helium.
The total mole fraction for any mixture of gases equals 1. Hence to get the mole fraction of the helium, we simply subtract the addition of the mole fractions of neon and argon from 1.
This means - 1 - 0.47 - 0.23 = 0.3
Now, to get the pressure of the helium gas, we simply multiply the total pressure by 0.3. This is 0.3 * 7.85 = 2.355 atm
Answer:
there are several types of Kinetic Energy: radiant, thermal, sound, electrical and mechanical.
Explanation:
Radiant energy is energy that travels in waves Its given off by electromagnetic radiation
Thermal energy results in an object or a system having a temperature that can be measured but it has to have motion
Sound a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid
Electrical When you let go of that ball and let it fall, the potential energy converts into kinetic energy
Mechanical is the result of its motion
Explanation:
my God what kinda learning you doing?
Answer:
74 or 74 kPa.
Explanation:
Hello,
In this case, based on the initial information, it is seen that the oxygen and the carbon dioxide form the mixture at 160 kPa, thus, by isolating the oxygen, its pressure will be equal to its initial partial pressure because it gets isolated, hence, we compute its molar fraction as:
Therefore, its initial pressure turns out:
Such pressure will be the oxygen's pressure once it is isolated. Finally, considering the request, the answer will be just 74 (by rounding to the nearest integer and without units).
Best regards.
