Answer:
1 mole of calcium contains 6.023
atoms.
Explanation:
1 mole is the amount of a substance that contains exactly
constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.
Hence, 1 mole of calcium will also have
atoms.
Number of atoms in 1 mole calcium = 6.023
atom
Answer:
I will say D. The molecules become arranged into regular cubic arrangement. but i'm not 100% sure
Explanation:
The accepted model of an atom was made by Schrodinger, which is known as the quantum mechanical model. Unlike Bohr's model, electrons are represented as a cloud and not small balls orbiting the nucleus. There is no define path of electrons in Schrodinger's model, but it can predict the odds of where an electron is located.
The answer to your question is then Electrons form a cloud around the nucleus.
Explanation:
precipitation like snow rain with increased acid is know as acid precipitation
Baking powder solution has an effect on a diluted hydrochloric acid solution by causing the release of carbon dioxide from sodium bicarbonate, a component of baking soda.
One molecule of backing soda + one molecule of hydrochloric acid yields one molecule of sodium chloride (table salt) + one molecule of carbon dioxide + one molecule of water.
HCl + NaHCO₃=NaCl+H₂CO₃
However, carbonic acid is quite unstable:
H₂CO₃ = CO₂ + H₂O
HCl + NaHCO₃ = NaCl + H₂O (Water) + CO₂.
Effervescence, which is a fast bubble formation, is how liquid releases CO2.
