It is A).
Electrons are negatively charged and an anion is a negatively charged ion so that means there is more electrons(negative charge) than protons(positive charge) in an anion
Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds. ... All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms.
2 carbon, 4 nitrogen, 8 oxygen
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature and moles.
Mathematically, P =
where, k = proportionality constant
Also, formula for initial pressure and volume is as follows.
or,
=
= 30 atm L
Now, we will calculate the value of as follows.
=
= 30 atm L
Hence, as this means that it signifies that gas obeys boyle's law.
Answer:
94.44
Explanation:
Volume is equal to Mass/Density so therefore, you do the mass which is 68.0 g/0.72 g/mL which is the density and get 94.44 mL because the g cancel each other out when it comes to the label!
