Answer: m-%(Ca) = 40.08 / 110.98
Explanation: molar mass of CaCl2 is 40.08+ 2·35.45 = 110.98
Think you have one mole substance. It contains 40.08 g Ca
It should be increasing the rate of the forward reaction will cause a shift to the left because the external stress, which is the increase in rate, will cause the reaction to be unbalanced, and to reach equilibrium it needs to shift to the right.
Answer:
2K + 2H₂O → 2KOH + H₂
Explanation:
The reactants are:
Potassium metal = K
Water = H₂O
The products are:
Potassium hydroxide = KOH
Hydrogen gas = H₂
The reaction equation is given as;
Reactants → Products
2K + 2H₂O → 2KOH + H₂
The reaction is a single displacement reaction
The high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants. Thus, Cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.
