The last option all of these answer choices relate to an electrolyte
Explanation:
Acids and bases which are strong but not weak are said to be strong electrolyte.
In salts, ionic salts which are soluble are called strong electrolyte.
KOH completely dissociates when added to solvent such as water and forms its dissociated ions - K+ and OH- which gets soluble in water and becomes standardized.
The ability to conduct electricity in solution occurs when the salt or ionizable molecules dissolved, its dissociated ions can move freely in solution, allowing a charge to flow.
Therefore according to the data above all the answer choices relate to an electrolyte.
A) 36.0 x 100 /2 = 1800 g Be
n = m / MM
stoichiometry 1:1
atomic mass of Be= 100 g/ mol
b) theoretical yield
Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard. On the other hand, each carbon in graphite is bonded to three carbons, and therefore graphite is formed in layers.
Answer: Option (b) is the correct answer.
Explanation:
To find molarity, firstly we need to calculate number of moles as follows.
No. of moles =
=
=
Therefore, molratity is defines as number of moles of solute present in liter of solution.
Molarity =
=
=
Thus, we can conclude that molarity of solution is .
Answer:
6 protons and 7 neutron
Explanation:
Carbon has a third isotopes named carbon-13
All carbon isotopes have 6 protons .
This is called atomic number. To make it up to 13 in carbon -13 you will need 7 neutrons and 6protons .
