Answer:
If the solution is not in contact with air, nothing will happen. If the solution is in contact with air, it will be not a reaction between copper, water and sodium chloride..
in the end there will be no reaction
Answer:
What are the characteristics of science? Objectivity: Scientific knowledge is objective. Verifiability: Science rests upon sense data, i.e., data gathered through our senses—eye, ear, nose, tongue and touch. Ethical Neutrality: Science is ethically neutral. Systematic Exploration.

Well a molecule of water is equal to 1 Oxygen and 2 Hydrogen each, so it'd be 2 molecules of water
If your talking about mole. p
1 mole of water weighs 18 g
Therefore 0.5 mole of water weighs 9 g
According to Avagadro,
1 mol = 6.023 **10^23
atoms
So,
0.5 mol = 3.0115 **10^23
molecules of water
Each water molecule contains 2 hydrogen atoms .
Therefore
2** 3.00115**10^23
atoms of hydrogen are present in 9g of water
Answer:
The answer is
6.02⋅1023
A. They are the same

Given
C3H6 and C4H8
Required
The percent compositions
Solution
%C = 3.12/42 x 100% = 85.71%
%H = 6.1/42 x 1005 = 14.29%
C₄H₈(MW=56 g/mol)
%C = 4.12/56 x 100% = 85.71%
%H = 8.1/56 x 100%=14.29%
So they are the same, because mol ratio of C and H in both compounds is the same, 1: 2
