Hey there !
a) Pb(SO4)2 => <span> lead(II) sulfate
b) </span><span>The molar mass of this compound was calculated from the amount of atoms of each element, with its respective atomic masses
Pb = 207.2 a.m.u
S = 32.065 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
</span>Pb(SO4)2 = 207.2 + 32.065 * 2 + 15.9994 * 8 => <span>399.3252 g/mol
</span>
hope this helps!
Answer:
alkalyene ch2+2n+h wbqlzl
Answer:
Acids:
Bases:
Explanation:
According to the Bronsted-Lowry acid-base theory, an acid is a proton donor and a base is a proton acceptor. In this case, notice that donates a proton, since after it loses a proton, it becomes a chloride anion. Therefore, is a Bronsted acid.
Similarly, is a proton acceptor and, therefore, a Bronsted base, since it becomes .
If we look at the reverse reaction, chloride can gain a proton to become , meaning it's a conjugate base.
Finally, is a conjugate acid, since it can donate a proton to chloride.
