Answer: Double displacement reaction
Explanation:
Double displacement reaction is defined as the reaction where exchange of ions takes place.
The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The chemical reaction between aqueous magnesium sulfate and aqueous sodium carbonate is represented as:
Answer:
density=1.43 g/L
Explanation:
Since the density formula is density = mass / volume, we need to find out the mass of the gas and the volume is that of the container.
The mass of the gas is 130.0318 g-129.6375 g=0.3943 g
The gas volume is 276mL*(1L/1000mL) 0.276 L
density = mass / volume=0.3943g/0.276L
density =1.43g/L
Answer:
Precipitate
Explanation:
A precipitate is a solid formed from a chemical solution
Answer:
they need the exchange so they can grow, obtain energy, and get rid of waste. It also helps to mantian a balance of amterials in the cell.
Explanation:
Answer:
A-B
C-D
E-F
I think it's these because Potential Energy increase when the graph increases and remain constant when the graph is flat.
