Answer:
Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)
Explanation:
Let's consider the molecular single displacement equation between Zn and Cu(NO₃)₂
Zn(s) + Cu(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Cu(s)
The complete ionic equation includes all the ions and insoluble species.
Zn(s) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ Zn²⁺(aq) + 2 NO₃⁻(aq) + Cu(s)
The net ionic equation includes only the ions that participate in the reaction and insoluble species.
Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)
Answer:
C is correct
Explanation:
A is wrong.
Lactose is a double sugar or disaccharide.
B. is wrong.
Sucrose is a double sugar as well as maltose . A double sugar is expected to contain 2 simple sugars. Sucrose contain glucose and fructose. Maltose itself is a double sugar.
C.is right
The three are simple sugar and they contain the exact atoms and numbers. In fact they are all isomers and essentially would have the same molecular formula. While glucose and fructose are functional group isomers, glucose and galactose are diastereoisomers.
D. is wrong.
Carbohydrates do not contain nitrogen
E. is wrong.
They are not simple carbohydrates but are polymers.
That means that one mole of sulfur has a mass of 32.065 grams. b) This compound contains two hydrogen atoms and one oxygen atom. To find the molar mass of H2O, we need to add the mass of two hydrogen atoms plus the mass of one oxygen atom. We get: 2(1.008)+16.00=18.016g/mol.
Substance A is Chlorophyll and substance B is Oxygen
“Flow is the volume of fluid that passes in a unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), or other various units.”
