I'm Osei George the answer is interference
Answer:deferehug
Explanation:
The mass of 3.0 x 10^23 atoms of neon would be 10.09 g
According to Avogadro;
1 mole of neon would have 6.022 x 10^23 atoms
3.0 x 10^23 atoms of neon would have:
3.0 x 10^23/6.022 x 10^23
= 0.5 moles
mass of 0.5 moles neon = mole x molar mass
= 0.5 x 20.18
= 10.09 g

Answer: The mass of neon for the given number of atoms will be 9.8 g.
Explanation:
We are given:
Number of neon atoms =
According to the mole concept:
number of atoms. are occupied in 1 mole of a substance.
So, will be occupied in =
To calculate the number of moles, we use the equation:
Moles of Neon = 0.49 moles
Molar mass of neon = 20 g/mol
Putting values in above equation, we get:
Hence, the mass of neon for the given number of atoms will be 0.49g.
(2) Cu(s) + 2AgNO3(aq) ==>2Ag(s) + Cu(NO3)2(aq)
(3) 2H2(g) + O2(g) ==>2H2O(l)
(4) KOH(aq) + HCl(aq) ==>KCl(aq) + H2O(l)
Answer : The correct option is, (1)
Explanation :
The option (1) reaction is an example of decomposition reaction because in this reaction the larger compound, calcium carbonate decomposes into smaller molecule, calcium oxide and carbon dioxide.
Decomposition reaction : It is a type of reaction in which a larger compound decomposes into a smaller molecule or elements.
The option (2) reaction is an example of single displacement reaction because in this reaction the most reactive metal, copper displace the less reaction metal, silver.
The option (3) reaction is an example of combination reaction because in this reaction two reactants, hydrogen and oxygen react to give a single product as water.
The option (4) reaction is an example of double displacement reaction because in this reaction a positive cation and a negative anion of two reactants exchange their places to give two new products.
Hence, the correct option is, (1)
a. True
b. False
Magma from Earth's interior oozes from the cracks at mid-ocean ridges.
true is the right one
silicon (#14)
cobalt (#27)
sodium (#11)
The element among the list that is not a metal there is the element fluorine.
A nonmetal is an element that occur towards the right hand side of the periodic table and does not have the general properties that are attributed to metals such as the ability to react with acids.
