Cobalt sulphate is the usual source of water-soluble cobalt since it is the most economical salt and shows less tendency to deliquesce or dehydrate
Answer:
1) Condensation.
2) See below.
Explanation:
1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.
2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.
It would be 59000000 milligrams
Answer:
E. Substance A will be the limiting reactant.
Explanation:
Below is a generic equation for a reaction.
2A + 3B → C + 3DA
According to the balanced equation, the theoretical molar ratio of A to B is 2:3, that is, 2 moles of A react with 3 moles of B.
<em>If I mix 2 units of A, with 6 units of B, which of the following is true?</em>
<em>A. There would be no reaction.</em> FALSE. The reaction will occur until the limiting reactant is over
<em>B. Both reactants will fully react.</em> FALSE.
<em>C. Not enough information given.</em> FALSE.
<em>D. Substance B will be the limiting reactant.</em> FALSE. Substance B will be the reactant in excess because there are 6 moles and only 3 moles are required.
<em>E. Substance A will be the limiting reactant.</em> TRUE.
