Answer:
Water can carry electricity
Explanation:
While pure water does not conduct electricity, ionized water does. It is common that water is ionized than is pure, unless it is purified. The dissolved ions in the water are what makes the water conduct electricity. Handling electric equipment with wet hands may lead to electrocution.
A. statement of fact meant to explain an action
Answer:
Option A. 11
Explanation:
The atomic number of an element does not change.
Recall:
Atomic number = proton number
If the atom is neutral, then,
Proton number = electron number
Since the element is sodium, then, the atomic number of sodium–25 is 11.
Also, we were told to obtain the electrons of a neutral atom of sodium–25
Therefore,
Atomic number = proton number = 11
Since the atom is neutral,
Proton number = electron number = 11
Answer: 53125joules
Explanation: The formula for kinetic energy is 1/2mv^2.
So we would have
1/2[(170)(25x25)]=53125
