Answer:
Velocity = 4.41×10⁵ m/s
Explanation:
The force of attraction between the nucleus and the electron is equal to the centrifugal force acting on the outermost electron due to circular rotation. It can be mathematically written as:
Where,
K is the Coulomb's constant having value 9×10⁹ N. m²/C²
q is the charge on the electron or the proton which is 1.6×10⁻¹⁹ C
r is the radius of the atom
m is the mass of the electron having value 9.1×10⁻³¹ Kg
v is the velocity of the electron.
The equation can be written to calculate the velocity as:
Given that:
r = 1.3×10⁻⁹ m
So,
<u>Velocity = 4.41×10⁵ m/s</u>
Answer:
P = 8000 Kg m/s
When speed is increased to 50 m/s,
P = 40,000 kg. m/s
Explanation:
Given data:
Mass = 800 Kg
Velocity = 10 m/s
Momentum = ?
Speed increased = 50 m/s
Momentum = ?
Solution:
Formula:
P = mv
P = 800 kg× 10 m/s
P = 8000 Kg m/s
When speed is increased to 50 m/s.
P = mv
P = 800 kg× 50 m/s
P = 40,000 kg. m/s
A
Bronsted-Lowry acid is a proton donor (usually hydrogen ion). And a
Bronsted-Lowry base is a proton acceptor (usually hydrogen ion). Consider a
chemical reaction between HCl and NaOH. We have the reaction HCl + NaOH à NaCl + H2O. The
hydroxide ions in the NaOH are bases because they accept hydrogen ions from
acids to form water. And an acid produces hydrogen ions in solution by giving a
proton to the water molecule. Therefore, the answer is d. a Bronsted-Lowry
base.
