1 meter = 1000 mm so 14mm x (1m/1000mm) = .014m
Answer:
Explanation:
Hello,
In this case, given the density and the mass of the aluminum foil, we can compute the occupied volume as shown below:
Next, since the volume is defined as:
Whereas accounts for its thickness, we can find it to be:
Regards.
Answer:
The answer is D; 1.45 x 10^-4
Answer:
The cohesive forces between the water molecules are very strong making the surface tension of water high. As surfactants absorb they break these interactions. The intermolecular forces between surfactant and water molecule are much lower than between two water molecules and thus surface tension will decrease

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.
