Answer:
- The NaCl solution will have higher boiling point.
Explanation:
- C2H6O2 is a molecular substance. Meaning that when it dissolves it will remain this way:
C2H6O2 ---------> C6H12O6 (aq)
- Sodiumchloride (NaCl) is an ionic substance. Meaning that when it dissolves, it will create ions:
NaCl(s)-------> Na+(aq) + Cl- (aq)
Conclusion:
- NaCl is an ionic compound and C2H6O2 is a molecular compound. Ionic compounds have higher boiling points than molecular compounds. Therefore, NaCl will have the higher boiling point.
Answer:
Explanation:
Every A will be paired with a T, and every C with a G and vice versa (T to A, and G to C)
So the first letters in the sequence are ATGGG. So the pair will be TACCC.
Answer:
iron oxide11
Explanation:
iron oxide is the chemical compound with formula fe304. it occurs in nature as the mineral magnetite.
Explanation:
When the student mixed the solution sodium carbonate with solution of copper(II) sulfate ; Copper Hydroxocarbonate , sodium sulfate and carbon dioxide gas was obtained as a products.
The balanced chemical reaction
Where:
= Copper(II) Hydroxocarbonate
= Sodium carbonate
= Copper(II) sulfate
= Sodium sulfate
= Carbon-dioxide
Answer:
Option A,+4
Explanation:
Oxidation state of any element is the sum of oxidation of all elements =0
Here we need to find oxidation no of carbon and consider oxidation no of carbon as X and oxidation number of oxygen is -2
Then X+2(-2)=0 (since 2 oxygen atoms are there in CO2 )
X-4=0
X=+4
