Answer:
Well what I put down was the purpose of it was to show how much force each amount of water would give
Explanation:
NaHCO₃ + H⁺ = Na⁺ + H₂O + CO₂
n(NaHCO₃)=n(H⁺)
m(NaHCO₃)=M(NaHCO₃)n(NaHCO₃)=M(NaHCO₃)n(H⁺)
p=$m(NaHCO₃)=$M(NaHCO₃)n(H⁺)
p=9.20$/kg×84.0kg/kmol×10⁻³kmol=0.7728$
p≈0.77$
Answer:
7 Valence Electrons.
Explanation:
The Valence electrons are referred to as the number of electrons in the outermost shell of an atom.
When given the electronic configuration, the valence can be calculated by adding the superscript of the hugest number coefficient.
The highest number coefficient in this electronc cnfiguration is 2. The sum of it's superscript is 2 (in 2s²) and 5 ( in 2p⁵). That is 2 + 5 = 7
How to test the answer?
The atom given has 9 electrons ( 2 + 2 + 5).
The K shell is being occupied by 2 electrons, the next shell; M shell which can occupy maximum of 8 electrons is being occupied by 7 electrons ( 9 - 7). And in this atom, the M shell is the outermost shell.
The correct answer is D. Cesium chloride is held together by ionic bonding. This substance is a salt like sodium chloride. It is also soluble in water. When it dissociates, it forms into cesium ions and chloride ions.
Answer: thermochromism, too hot of temperature or long exposure to high temperature may completely degrade the color of an object. In other instances, an object or sample changes to another shade of color until it stabilizes back to room temperature.
