Answer:
90 neutrons
Explanation:
#neutrons = Atomic Mass - Atomic Number
= 170 - 80 = 90 neutrons
The only given information is the time in 3 seconds. We are asked to find the position, or the distance traveled. The working equation to be used here is:
x = v₀t + 1/2 at²
where
x is the distance
v₀ is the initial velocity
a is the acceleration
In order to solve this, let's assume the object is free falling. So v₀ = 0 and a = 9.81 m/s².
x = 0 + 1/2 (9.81)(3)²
x = 44.145 meters
Answer:
2
Explanation:
In calcium oxide, the calcium is electropositive in nature and to fulfil its octet, the calcium atoms lose two electrons to form the calcium cations whose valency is 2, hence the corresponding anion, i.e. the oxide anion must also have valency 2 to balance the positive charge on the calcium cation.

Explanation:
Answer:
ethanol
Explanation:
CO2 is carbon dioxide
C2H5OH is ethanol and we know that because that is what is left after taking out the CO2
