Answer:
1.852 g of CO2 were produced in the chemical reaction
Explanation:
The problem is pretty simple. We can write down the chemical reaction that is involved to help us understand better what is going on in the process:
CaCO3 (aq) + HAc (aq) → CaAc (aq) + CO2 (g) + H2O (l)
Let's think this through: we have a tablet that has an active compound (CaCO3) and an inert substance that weighs 0.833 g. When we add 58.072 g of an acid solution (represented in the equation as HAc because we are not told specifically which acid is being added), CO2 is formed and released from solution as gas leaving us with an aqueous solution that weighs 57.053 g.
Having said that, we know that the only mass lost during the reaction is due to the formation of CO2 gas. Therefore, we sum the reactants (the tablet + the acid solution) and subtract the mass of the remnant solution. This value will indicate us the amount of CO2 formed:
0.833 g of the Tablet + 58.072 g from the Acid solution = 58.905 g
58.905 g of reactants - 57.053 g of remnant solution = 1.852 g of produced CO2.
Answer:
ionic bond
Explanation:
Covalent bonds are formed when two or more atoms share electrons between them. So two chlorine anions form an ionic bond with one magnesium cation for form MgCl2, a neutral chemical compound.
Same speed as Continental drift
Answer:
Explanation:
The kPa-kilopascal is the unit of pressure. It was named after Blaise Pascal, a mathematician and physicist.
The kPa is 1000Pa. Kilo stands for 1000. Now what is a pascal?
A pascal is the amount of force(Newton) exerted per unit area.
1Pa = 1Nm⁻²
At the standard atmospheric level, the pressure is 101.325 x 10³ Nm⁻² i.e the atmosphere exerts a pressure of 101.325 x 10³N in an area of a body.
This unit is used to calculate pressure. It can be converted to other units.
solution:
A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
Starting by hitting acetylene with NaNH2 to deprotonate, this C-- will attack the C connected to the Br Sn2 style to lengthen the chain by two carbons.
Do this same thing again with the other CH of the acetylene and another bromoethaneto get a six carbon chain, namely, 3-hexyne.
Now, reduce the alkyne to an alkene via H2/Pd/C, and that gives 3-hexene.
