Answer : The number of moles of water will be, 1.235 moles
Solution : Given,
Mass of 
= 42 grams
Molar mass of = 34 g/mole
First we have to calculate the moles of
Now we have to calculate the moles of water.
The balanced chemical reaction will be,
From the balanced reaction, we conclude that
As, 2 moles of decomposes to give 2 moles of water
So, 1.235 moles of decomposes to give 1.235 moles of water
Therefore, the number of moles of water will be, 1.235 moles
A chemical change is the answer
Answer:
Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons.
Explanation:
Answer:
a. Cl (g) + KBr (aq) = Br (l) + KCl (aq)
b. Al (s) + I (s) = AlI (s)
c. Mg (s) + HCl (aq) = MgCl (aq) + H2 (g)
Explanation:
The reactants are the elements before the equals sign and the products are the ones after the equals sign that are bolded.
