Explanation:
Young babies need a lot of calcium because calcium makes bones strong ,it protects them against bone loss in future,and it also prevents them from a disease called rickets.
Answer:
See explanation below
Explanation:
This reaction is known as the Grignard reaction. If's often used to add an alkyl to a molecule, in this case, a ketone. This also helps to reduce the carbonile to an alcohol.
The mechanism is taking place in 3 steps.
The first step involves the attack of the pair of electrons of the oxygen from the cyclohexanone to the MgBr, and the other pair takes the propyl.
The second step involves the breaking of this bond to have the OMgBr and the propyl attached to the carbon of the chain.
The last steps involves an hydration of the molecule, to turn the OMgBr into OH, and that would be the final product.
In this case, the final product will be 1-propyl-cyclohexanol.
The picture below, shows the mechanism and the drawing of the final product.
Answer:
Explanation:
3BaCl₂(aq) + 2Na₃PO₄(aq) = Ba₃(PO₄)₂ + 6NaCl(aq)
3 x 208 g = 624 g 2 x 164 g = 328 g
328 g of Na₃PO₄ reacts with 624 g of BaCl₂
.611 g of Na₃PO₄ reacts with 624 x .611/328 g of BaCl₂
624 x .611/328 g = 1.16 g of BaCl₂
BaCl₂ available is .504 g which is less than required .
Hence BaCl₂ is limiting reagent .
Molarity = mol/L
density= grams/ mL
this is a conversion problem where we have to change the numerator from grams to moles, and the denominator from ml to L.
First, we need our conversion factors
1 liters= 1000 mililters
to convert the mass to moles, we need the molar mass of the compound acetic acid (CH3<span>COOH)
molar mass of </span>CH3<span>COOH is </span><span>60.05 g/mol, which can be calculated by going to the periodic table and add the mass of the each atom in the compound formula.
1.049 g/ ml (1 mol/ 60.05 grams)= 0.0175 mol/ ml
0.0175 mol/ ml (1000 ml/ 1 liters)= 17.5 mol/ L or 17.5 M
