Answer:
Distance between the carbon atom = 491 pm
Explanation:
Given:
1 pm = 1 × 10⁻¹² m
Distance between the carbon atom = 2.81 × 10⁻⁸ cm
Find:
Distance in picometers
Computation:
Distance between the carbon atom = 2.81 × 10⁻⁸ cm = 491 X 10⁻¹² m
Distance between the carbon atom = 491 pm
The oxidation number of oxgyen is -2. In the compound, the total charge of oxygen is -12. Fe has a charge of +2. To make the sum equal to zero, N has to have a charge of +5. -12+2+2x=0; x= +5.
Answer:
The hydronium ion in neutral solution has the concentration of 1.0 x 10⁻⁷.For acidic solution, the concentration of hydronium ions is greater than 1 × 10⁻⁷ that the pH be lower than 7.
Explanation:
Refers to the number of neutrons in the nucleus of an atom
steam at 105 °C because gas particles are the most mobile and mobility increases with increasing temperature
Explanation:
The substance with the highest mobility would be steam at 105 °C because gas particles are the most mobile and mobility increases with increasing temperature.
Mobility is the movement of the particles in a medium.
It increases the randomness of particles.
- Of all the states of matter, gases are the most random of all.
- Also, mobility increases with increase in kinetic energy.
- As temperature increases, kinetic energy will also increase and cause more mobility.
