C) All of the animals would eventually run out of food and die.
Mark with crown please!
Shown above are three simple diatomic molecules. On the left is H2, with a single bond between the H atoms. Since two H atoms have the same electronegativity, they share the electrons evenly. Fluorine is much more electronegative than hydrogen, so the majority of electron density resides on the fluorine atom.

First step: calculate the number of moles of sodium reacted
moles=mass/molar mass
31.5g/23g/mol =1.37moles
from the reaction above the reacting ratio of Na to H2 is 2:1 therefore moles of H2 is 1.37/2=0.685
At STP 1 mole = 22.4L what about 0.685 moles
22.4 x0.685=15.344L
Answer: has zero mass
is an electron
has a -1 charge
is electromagnetic energy
Explanation:
A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.
The beta particle released is basically a electron with -1 charge and no mass.
General representation of beta particle in the form of given as
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
By increasing Atomic number
