Answer:
pH= 8.45
Explanation:
when working with strong accids pH = -log(Concentration)
so -log(3.58e-9) = 8.446
To solve for the absolute temperature, we assume ideal gas
behaviour so that we use the equation:
PV = nRT
or T = PV / nR
So calculating:
T = [6.6 atm * 0.40 L] / [(2.4g / 28g/mol) * 0.08205746 L
atm / mol K]
<span>T = 375.35 K</span>
Answer:
C. Br and Cl
Explanation:
The pair that will share electrons when a bond forms between them is Br and Cl.
When electrons are shared between two atoms to form a bond, then the bond type formed is called a covalent bond.
- A covalent bond forms between non-metals.
- Br and Cl are non-metals
- The electronegativity difference between the species must be very low or zero.
- This is the case for the two non-metals.
