Explanation:
Moles of KCl in new solution = 0.325dm³ * (2.76mol/dm³) = 0.897mol.
Hence volume needed = 0.897mol / (3.95mol/dm³) = 0.227dm³ or 0.227L.
Answer:
im pretty sure they heat up
Explanation:
as they use energy to go from solid to liquid to gas, they need heat to do so as they have a melting and boiling point
Answer: Carbon Hydrogen and water
1:2:1
Explanation:
Carbohydrates are made of Carbon Hydrogen and water. Hence, they are represented by a general formula Cx(H2O)y.
Carbohydrates have carbon, hydrogen and oxygen in ratio 1:2:1, as is found in glucose (C6H12O6), Glycerose (C3H6O3), Ribose (C5H10O5).
Thus, in all sugars carbon, hydrogen and oxygen are found in ratio 1:2:1
Answer:
The symbol for an atom indicates the element via its usual two letter symbol, the mass number as a left superscript, the atomic number as a left subscript (sometimes omitted), and the charge as a right superscript.
