<span>The relationship between the number of carbon atoms and boiling point is inversely proportional. In the alkane series of hydrocarbons, as the number of carbon atoms decreases, the normal boiling point of the compounds decreases. The reason behind this is that longer chains of molecules require more energy to separate the bonds while shorter chains or molecules with lower number of carbon atoms require less energy to break away from each other. Thus, low carbon molecules have lower boiling point.</span>
pH. 10 because it is strong base
The given question tells you that a certain piece of wire has a mass = 2.0 g per meter
That means that if you consider a piece of wire that is 1 m in length, its mass will be equal to 2.00 g .
According to question,
Now, you know that
1 m = 100 cm
Mass of 2.00 g of copper will correspond to a wire that is a 100 cm long.
This implies that 0.28 gof copper will correspond to a wire that is
0.28 g * 100 cm / 2.0 g = 14 cm long
Hence, 14 cm of the wire would be needed to provide 0.28 g of copper.
Properties of Copper :
High conductivity and ductility.
Non magnetic.

Answer:
The correct answer is option e.
Explanation:
The formula used for root mean square speed is:
where,
= root mean square speed
k = Boltzmann’s constant = 
T = temperature
M = Molar mass
= Avogadro’s number = 
Root mean square speed of carbon dioxide molecule:
Temperature of the mixture = T =?
Molar mass of carbon dioxide = 44 g/mol = 0.044 kg/mol
T = 533.87 K
Root mean square speed of nitrogen molecule:
Molar mass of nitrogen = 28 g/mol = 0.028 kg/mol
689 m/s is the root-mean-square speed of the nitrogen molecules in the sample.
Answer:
Solution Concentration: Molarity Moles of solute in one liter of solution Used because it describes how many molecules of solute are in each liter of solution Tro: Chemistry: A Molecular Approach, 2/e 6 amount of solute (in moles) Molarity, M = amount of solution (in L) moles of solute M = L of solution or simply 4
GOOD LUCK!!
