Answer:
134K
Explanation:
Using the ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas constant (0.0821 Latm/Kmol)
T = temperature (K)
Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?
3.25 × 4.738 = 1.4 × 0.0821 × T
15.3985 = 0.11494T
T = 15.3985/0.11494
T = 133.969
Approximately;
T = 134K
HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
= 0.745
Thus the pH of the mixture is 0.745
Answer:
B
Explanation:
pure water can accumulate to form ice while pushing the salt particles to be accumulated in the liquid part, because salt particles are more favorable to stay in liquid than ice
so there can still be some salt in the ice between the bonds
Organic chemistry was definitely harder for me, though this is a matter of opinion and learning style. If you are good with logic, then organic chemistry might not be so hard, or at least that's what my professor said. A lot of physics was just knowing how to use formulas and then plugging and chugging, and knowing basic outcomes of physical reactions. It's a whole other story if you take calculus based physics.
Good luck.
Answer:
true
Explanation:
Polyatomic ions are covalent compounds that have an overall charge. In the ammonium ion, NH4 , nitrogen is covalently bonded (shares electrons)to four separate hydrogen atoms
