The real situation with this is that if since both proteins and DNA contain carbon and oxygen, both molecules in the phage progeny would have received the radioactive isotopes. Hershey and Chase would have been unable to isolate only DNA molecules or proteins that contain the radioactive isotopes of these elements.
Answer:
Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

Answer:
22.22 g
Explanation:
The balanced reaction equation is;
Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)
Number of moles of calcium reacted = 8.02g/40.1g/mol = 0.2 moles of Calcium
From the reaction equation;
1 mole of Ca yields 1 mole of CaCl2
Hence 0.2 moles of Ca also yields 0.2 moles of CaCl2
Mass of calcium chloride produced = number of moles * molar mass
Mass of calcium chloride = 0.2 moles of CaCl2 * 111.1g/mol = 22.22 g

See explanation
Explanation:
A word equation tries to depict a chemical reaction in words. Letters rather than only chemical formulas are used to show the reaction equation.
Now we want to write a word equation that shows the reaction of sodium hydroxide solution and aluminium sulphate solution:
Alumunium sulphate + sodium hydroxide ------>Aluminium hydroxide + sodium sulphate
