Answer:
The oxygen atom has a slightly negative charge.
Explanation:
3.5 - 2.5 = 1
For ionic bond electronegativity should be more than 1.6.
So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.

The lights shown in the figure comes from the outermost layer of the Sun. This layer is called photosphere. This is the layer from where the light of the Sun is radiated, before travelling through space and reaching us.
Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure
Answer:
Explanation:
Given parameters:
Number of breathe per minute = 15times
Volume of air per breath = 0.5L
Percentage of oxygen in air = 21%
Solution
There are 24 hours in a day.
60minutes makes a hour in a day,
I will breathe:
15 times x 60 x 24 = 21600 times in a day
The volume of air I will take in per day:
A breathe = 0.5L of air
21600breathe = 0.5 x 21600 = 10800L of air
Volume of oxygen I will breathe per day:
x 10800 = 2268L of oxygen
Answer:
False
Explanation:
Because laws and theories are developed for different purposes, laws never become theories, and theories do not become laws.
