Answer:
false
Explanation:
It is the opposite. Atoms are the smallest.
Answer:
Sr(OH)₂(aq) + 2 HNO₃(aq) ⇒ Sr(NO₃)₂(aq) + 2 H₂O(l)
Explanation:
Let's consider the unbalanced molecular equation between strontium hydroxide and nitric acid solutions. This is a neutralization reaction, since an acid reacts with a base to form a salt and water.
Sr(OH)₂(aq) + HNO₃(aq) ⇒ Sr(NO₃)₂(aq) + H₂O(l)
We have 2 N atoms on the right side, so we have to multiply HNO₃ by 2.
Sr(OH)₂(aq) + 2 HNO₃(aq) ⇒ Sr(NO₃)₂(aq) + H₂O(l)
Finally, to get the balanced equation we will multiply H₂O by 2.
Sr(OH)₂(aq) + 2 HNO₃(aq) ⇒ Sr(NO₃)₂(aq) + 2 H₂O(l)
Answer:
1) 1,8066*10^24 molecules of water
2)2,4088*10^24 atoms of carbon
3)4,8176*10^24 atoms of oxygen
4)2,6071*10^23 molecules og NaCl
5)107,221 g of calcium bromide
6)0,0814 moles iron III nitrate
Explanation:
Ba-F bond has the highest degree of uneven sharing because the difference between the electonegativity of F (which is 4.0) and Ba (0.89), is the largest of all other bonds
Answer: d) The volume occupied by the molecules themselves is no longer negligible. This most be the answer because a, b and c don't make any sense at all.
