Answer:
The answer to your question is a) Covalent b) Ionic
Explanation:
Data
Kind of bond between C - C
kind of bond between Mg -Cl
Process
1.- Look for the electronegativities of these elements
Carbon electronegativity = 2.55
Magnesium electronegativity = 1.31
Chlorine electronegativity = 3.16
2.- Calculate the difference of electronegativities
a) C - C = 2.55 - 2.55 = 0
b) Mg - Cl = 3.16 - 1.31 = 1.85
3.- Kind of bond
a) It's covalent because the difference of electronegativity was lower than
1.5.
b) It's ionic because the difference of electronegativity was higher than 1.5.
Answer:
C3H6
Explanation:
We can obtain the molecular formula by using the empirical formula and the molar mass in combination.
This is shown below:
[CH2]n = 42g/mol
We then add the atomic masses of carbon and hydrogen and multiply by n to give the value of n .
n[12 + 2(1)] = 42
14n = 42
n = 42/14 = 3
The molecular formula is thus [CH2]3 = C3H6
The closer to the top the metal is in the list, the more active the metal is and the stronger a reducing agent the metal is. When two different metals are involved in a redox reaction, the metal higher in the list will be oxidized and give up electrons that will reduce the cation of the less active metal.
Answer: It will produce 40 chloride ions
Explanation: When in water, Calcium chloride separate in ions, as the following chemical equation:
CaCl₂ + H₂O ⇒
According to the equation, 1 calcium chloride results in 2 chloride ions, so if there are 20 units of the chemical compound, there will be 2 times as much Chlorine ions, i.e., 40 units of chlorine ions.
