A flight simulator that helps astronauts prepare for a shuttle launch is an example of a Scientific Model.
Answer:
a. 58.5 g/mol
b. 0.1 mol
Explanation:
a.
The molar mass of Na is 23.0 g/mol. The molar mass of Cl is 35.5 g/mol. The molar mass of NaCl is:
M(Na) + M(Cl) = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol
b. A healthy adult should eat no more than 6 g of salt in one day. The moles corresponding to 6 g of NaCl are:
6 g × (1 mol/58.5 g) = 0.1 mol
Density = mass / volume
8.96 = m / 7.00
m = 8.96 x 7.00
m = 62.72 g
the hybridization is probably sp2. it will have 1pi bond. There is a double bond between C and O atoms and that double bond consists of 1 pi bond and 1 sigma bond.
