The equation NaHco3+hc2h3o2=nac2h3o2+h2co3 is already balanced.
Reaction information:
Nahcolite + Acetic Acid = Sodium Acetate + Carbonic Acid
Reactants:
Nahcolite - NaHCO3 :
Molar Mass, Oxidation State
Acetic Acid - HC2H3O2
Molar Mass, Oxidation State, Ethanoic Acid, Methanecarboxylic Acid, Ch3-Cooh, Acetic Acid; Glacial, etc
(NaHCO3 + HC2H3O2 = NaC2H3O2 + H2CO3)
Answer:
<h2>1.8662 × 10²⁴ atoms</h2>
Explanation:
The number of atoms can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
N = 3.1 × 6.02 × 10²³
We have the final answer as
<h3>1.8662 × 10²⁴ atoms</h3>
Hope this helps you
Answer:
The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12.
Or
Its just another term for atomic mass.
Explanation:
Answer:
a) False ( all metals are not magnetic for ex - gold is not magnetic )
b) false ( Diamond is a solid non metal still it shine)
c ) False ( mercury metal is liquid at room temperature)
d) True
e) False (Non metals are bad conductor of heat and electricity )
Answer: Option (a) is the correct answer.
Explanation:
According to thermodynamics, a closed system is defined as the system in which there will be no exchange of matter takes place but there will be exchange of energy between the system and surrounding.
On the other hand, an open system is defined as the system in which there will be exchange of both matter and energy takes place between system and surrounding.
Hence, we can conclude that out of the given options accurate descriptions of closed and open thermodynamic processes is that open processes are 'flow through' processes.
