White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.
The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.
Answer: 131 g of bromine is required.
Explanation:
The balanced equation will be :
To calculate the moles, we use the equation:
moles of 
According to stoichiometry :
2 moles of require = 3 moles of 
Thus 0.544 moles of require=
of
Mass of 
Thus 131 g of bromine is required.
Answer:
<h3>
C. 3</h3>
Explanation:
there are three electrons in a 2p sub-energy level of s neutral nitrogen atom.
The mass number of an atom : 26
<h3>Further explanation</h3>
Given
12 protons, 14 neutrons, and 12 electrons
Required
The mass number
Solution
Inside the atom there are 3 sub-particles, namely protons, neutrons and electrons. Protons and electrons are present in the atomic nucleus while electrons move around the atomic nucleus through energy levels in the atomic shell
Atomic number = number of protons = number of electrons
Mass number = number of protons + number of neutrons
Input the value :
Mass number = 12 + 14
Mass number = 26
