Answer:Boron
Explanation:
it is element 5 represented by the letter B
Answer:
2.5M
Explanation:
Molarity is the measure of the molar concentration of a solution. It is calculated using the formula below:
Molarity = n/V
Where;
n = number of moles (mol)
V = volume (L)
According to the information about Calcium chloride (CaCl2) provided in this question;
n = 0.5moles
M = 0.20M
Molarity = 0.5/0.2
Molarity = 2.5M
D is asking basically asking if would you get the same results if the tubes had salt instead of sugar
The ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P
Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K
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.
