Answer:
Ionic or electrovalent bonds
Explanation:
The bond type that will result when the two atoms combine is an electrovalent or ionic bond. This is due to the large electronegativity difference between the given species.
- An ionic bond usually forms between metals and non-metals.
- The metal being electropositive has a very low electronegativity value.
- Non-metals are electronegative.
- The Cs will lose it electrons to F
- This leaves a net negative charge on F and a net positive charge on Cs.
Balanced chemical reaction:
2NaCl(aq) + Hg₂(C₂H₃O₂)₂(aq) → Hg₂Cl₂(s) + 2NaC₂H₃O₂<span>(aq).
</span>NaCl - sodium chloride.
Hg₂(C₂H₃O₂)₂ - mercury(I) acetate.
NaC₂H₃O₂ - sodium acetate.
Hg₂Cl₂ - mercury(I) chloride or <span>mercurous chloride</span>, low solubility in water.
Oxidation number of sodium is +1 and for mercury is also +1.
Answer:
A - Is the material malleable or ductile?
Explanation:
Answer: -
100 grams
Explanation: -
Mass of Oxygen = 40 g
Chemical formula of oxygen gas = O2
Molar mass of oxygen = 16 x 2 = 32 gram
Atomic mass of Mg = 24g
Molar mass of MgO = 24 x 1 + 16 x 1 =40 gram
The balanced chemical equation for the reaction is
2Mg + O2 -- > 2 MgO
So from the balanced equation we see that 1 O2 react to give 2 MgO
32 grams of O2 react to give 2 x 40 gram of MgO
40 grams of O2 react to give
=100 gram of MgO
