The answer is (C) The electrons are moving easily between the nuclei of metal atoms.
The explanation:
-The electrons then move freely throughout the space between the atomic nuclei. ... Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current. Metals are ductile and malleable because local bonds can be easily broken and reformed.
1-Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current.
2-Metals are ductile and malleable because local bonds can be easily broken and reformed.
3-Metals are shiny. Light cannot penetrate their surface; the photons simply reflect off the metal surface. However, there is an upper limit to the frequency of light at which the photons are reflected.
Answer:
V₁ = 96.2 mL
Explanation:
Given data:
Initial volume of NH₄OH required = ?
Initial molarity = 15.6 M
Final molarity = 3.00 M
Final volume = 500.0 mL
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume of NH₄OH
M₂ =Final molarity
V₂ = Final volume
Now we will put the values.
15.6 M ×V₁ = 3.00 M×500.0 mL
15.6 M ×V₁ = 1500 M.mL
V₁ = 1500 M.mL /15.6 M
V₁ = 96.2 mL
Answer:
Because it contains only two elements.
Explanation:
A binary compound is a compound made up of only two elements. Barium chloride contains:
1. Barium.
2. Chlorine.
Since Barium chloride contains only two elements, it is therefore a binary compound.
Potassium Iodide have a lot of strong bonds which requires a very high temperature (high energy) to break them and change into a different state of matter.
Answer:
2HNO3+Ca(OH)2 = Ca(NO3)2+2H2O
Explanation:
The reaction between Nitric acid(HNO3)and Calcium hydroxide(Ca(OH)2) gives Calcium Nitrate( Ca(NO3)2 and Water( H2O)
