Answer:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone
Answer:
24000
Explanation:
Given that:
The numbers of carbon atoms = 8000
According to the Einstein model of solid;
Einstein’s model assumes that each atom of the solid vibrates around its position of equilibrium independently of the other atoms (which amounts to neglecting the interactions between particles.
Number of oscillators = 3(8000)
Number of oscillators = 24000
Answer:
Increases by 100 Pa
Explanation:
According to The Ideal Gas Equation,
- the temperature of the gas is directly proportional to the volume of the gas present in it
- If the temperature rises from 100 K to 200 K, then the volume will increase by 100 Pa (standard unit of Pressure)
Answer:
2, strong acid
Explanation:
Data obtained from the question. This includes:
[H+] = 0.01 M
pH =?
pH of a solution can be obtained by using the following formula:
pH = –Log [H+]
pH = –Log 0.01
pH = 2
The pH of a solution ranging between 0 and 6 is declared to be an acid solution. The smaller the pH value, the stronger the acid.
Since the pH of the above solution is 2, it means the solution is a strong acid.
Answer:
A
Explanation:
CH4+O2-CO2+ H20
that mean methane has burn in oxygen to produce CO2
