Answer:
True
Explanation:
Fungi reproduce by spawning absurd amount of spores greatly increasing the survival rate of the fungi.
The formula for pH given the pKa and the concentrations
are:
pH = pKa + log [a–]/[ha]
<span>
Therefore calculating:</span>
3.75 = 3.75 + log [a–]/[ha]
log [a–]/[ha] = 0
[a–]/[ha] = 10^0
<span>[a–]/[ha] = 1</span>
Answer:
SO2 is bonded covalently
Explanation:
Atoms that share electrons in a chemical bond have covalent bonds.
Answer: 4.4 x 10^-7
Explanation:
The dissociation equation for this reaction is:
MgCO3 (s) → Mg+2 (aq) + CO3-2 (aq)
(Here 0.08 >>> x )
So the solubility MgCO₃ in a solution that containing 0.080 M Mg²⁺ is 4.4 x 10^-7
The answer is B. Each chlorine has three non-bonded pairs and one bonded pair of electrons.
I just took the test and it was correct! 5/5 :)
