It’s C because wood isn’t easy to get heat through while metal can heat up quickly.
Answer:
1) 7.256 mol Br2 (Cl2)/(Br2)
The Br2 cancels out, so we have 7.256(2)
This is 14.512.
2) Number of moles = mass / molar mass
Number of moles = 239.7 g/ 35.5 g/mol
Number of moles = 6.8 mol
BrCl=13.6 mol
13.6(11.5.357)
1568.9 g
3) Repeat the same process with problem 2, given that there are 6.022x10^23 atoms in a mole.
Explanation:
Br2 + Cl2 → 2BrCl
Nucleic Acids, Protein Coat,and Lipid Membrane
Answer:
A. electric current is continuous and static electricity is not continuous
Explanation:
Electric current is a continuous flow of electrons. For example, through a circuit.
Static electricity is the movement of charges (like electrons) from one object to another. For example, when you rub your feet on carpet and then touch a doorknob, that's static electricity. The electrons move from your body to the doorknob, resulting in a shock, and then they stop.
Hope that helps.
Answer:
pH = 0.81
Explanation:
HCl reacts with aniline, thus:
C₆H₅NH₂ + HCl → C₆H₅NH₃⁺ + Cl⁻
Moles of HCl are:
0.085L × (0.35mol HCl / L) = <em>0.02975mol HCl</em>
Moles of aniline are:
0.030L × (0.40mol HCl / L) = <em>0.012mol aniline</em>
Thus, after reaction, will remain:
0.02975mol - 0.012mol = <em>0.01775mol HCl</em>
Moles of HCl in solution are equal to moles of H⁺, thus, moles of H⁺ are: <em>0.01775mol H⁺</em>
As total volume is 85.0mL + 30.0mL = 115.0mL ≡ <em>0.115L</em>
0.01775mol / 0.115L = 0.1543M
pH of solution = -log[H⁺]
pH = -log 0.1543M
<em>pH = 0.81</em>
