Answer:
0.43 g/ml
Explanation: Density is d = M/V, where d is density, M is mass, and V is volume: therefore d= 32 g/75ml = 0.4266 = 0.43 g/ml
Answer:
The state of matter is liquid
Explanation:
Since the frozen point in celcius is 32 then at 30 its still liquid
Answer:
During this reaction electron is transfer from copper to silver.
Explanation:
Ionic equation:
Cu + 2Ag⁺ → Cu²⁺ + 2Ag
Given equation shows that the silver on left hand side is present in the form of cation. The charge on silver is +1 it means one electron is lost by one silver atom. While copper is present in neutral form with oxidation state zero.
Thus copper lose two electron and gain +2 charge these two electrons are accepted by two silver atoms and became neutral.
This equation shows the redox reaction.
Silver gets reduced by gaining the electron and copper gets oxidized by losing the electrons.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Ammonia
is NH₃. Hydrogen chloride is HCl. Ammonium chloride is NH₄Cl.
NH₃
+ HCl --> NH₄Cl
