When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
Answer:
B. tension
Explanation:
a straight stretched rubber band experiences tension which is a stress that tries to pull matter apart.
Solution :
Molar mass of 
is :
M = 6×12 + 6×1 g
M = 78 g
78 gram of contains 
molecules.
So, 89.5 gram of contains :
Now, from the formula we can see that one molecule of contains 2 hydrogen atom . So, number of hydrogen atom are :
Hence, this is the required solution.
Answer:
dude! it's static!
Explanation:
a dry cell can't function and is therefore static!
When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.
