Lilit [14]4 years ago
3 0

Explanation:

Chlorine atom has an atomic number of 17

Electronic configuration

Cl = 1s2 2s2 2p6 3s2 3p5

Cl- = 1s2 2s2 2p6 3s2 3p6

Soduim atom has an atomic number of 11

Electronic configuration

Na = 1s2 2s2 2p6 3s1

Na+ = 1s2 2s2 2p6

Calcium atom has an atomic number of 20

Electronic configuration

Ca = 1s2 2s2 2p6 3s2 3p6 4s2

Ca2+ = 1s2 2s2 2p6 3s2 3p6

Azurite, 2 CuCO3 * Cu(OH)2 is blue and malachite, CuCO3 * Cu(OH)2 is green. Which contains the higher percentage of copper? Each
blagie [28]

Answer:

Malachite green has highest percentage of copper.

Explanation:

Azurite: 2CuCO_3.Cu(OH)_2

Molar mass of Azurite = M = 344.67 g/mol

Atomic mass of copper = 63.55 g/mol

Percentage of copper in Azurite :

Cu\%=\frac{3\times 63.55 g/mol}{344.67 g/mol}\times 100=55.31\%

The percentage of copper in an azurite is 55.31%.

Malachite: CuCO_3.Cu(OH)_2

Molar mass of Malachite = M = 221.12 g/mol

Atomic mass of copper = 63.55 g/mol

Percentage of copper in Malachite:

Cu\%=\frac{2\times 63.55 g/mol}{221.12 g/mol}\times 100=57.48\%

The percentage of copper in an malachite is 57.48%.

How does velocity and mass affect momentum?
ollegr [7]

Velocity and mass are directly proportional to the quantity of momentum by:

p = mv. Therefore, and increase in either velocity or mass will lead to an increase in momentum and vice versa. Momentum during a reaction is always conserved, meaning that the mass and initial velocity before a reaction will always be equal to the change in mass and velocity produced after the reaction. Kinetic energy after a reaction, however, is not always conserved. For example if a fast moving vehicle collided with a stationary vehicle, and moved together, the overall kinetic energy would be after the reaction, as a heaver mass would be moved by the same velocity causing a decrease in kinetic energy.

I don't know if this is exactly what you are looking for, but in physics this is how it is understood.

which particle diagram shown above best represents the strongest intermolecular force between two ethanol, c2h6o, molecules?
Yuki888 [10]

The strongest intermolecular bonding in ethanol is hydrogen bonding.

Intermolecular forces are the forces that hold two molecules of a substance together in a given state of matter. For ethanol, the strongest intermolecular force is hydrogen bonding.

Hydrogen bonding occurs when hydrogen is directly linked to a highly electronegative element such as oxygen, nitrogen, fluorine or sulfur. The existence of intermolecular hydrogen bonds accounts for unusual properties such as abnormally high melting and boiling points.
