Answer:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
Answer:
Waxing Gibbous
Third quarter
Waning Gibbous
Explanation:
If moon rises at 3:00 pm then the phase of the moon will be "Waxing Gibbous".
This is because, the moon is actually not fully illuminated but has achieved more than half of its full illumination.
If the moon is highest in the sky at sunrise then the phase of the Moon will be the "Third quarter"
This is because of the fact that at this position moon will rise at midnight, thus it will be at the highest point at the time of the sunrise.
If the moon sets at 10:00 am then the phase of the Moon is "Waning Gibbous"
This is because of the fact that at this position the Moon is moving towards becoming new Moon but at the same time, the moon is illuminated more than its half illumination.
Answer:
time is 3333.33 min or 55.55 hr
Explanation:
given data
reactor operating = 1 MW
negative reactivity = $5
power = 1 miliwatt
to find out
how long does it take
solution
we know here power coefficient that is
power coefficient = 
power coefficient = 1
so time required to reach power is
power = reactivity × time / power coefficient + reactor operating
1 ×
= -5 t / 1 + 1 × 
5t =
- 
t = 199999.99 sec
so time is 3333.33 min or 55.55 hr
Batteries supply electrons to the circuit by releasing negatively charged atoms or ions. These ions are produced by the batteries through a chemical reaction that spontaneously occurs within the battery. So the negative end of the battery pushes the ions towards the positive end of the circuit with the help of the voltage. This is why eventually, batteries "run out" when the electrode is used up and the chemical reaction can no longer continue.
