Ca(C2H302)2(aq) + Na2CO3(aq) —> CaCO3(s) + 2 NaC2H302(aq)
Answer:
an ideal gas does not exist except as a conceptual notion, an ideal. Physicists and chemists idealized the behaviour of real gases so that they could explain these phenomena. Under conditions of low pressure and high temperature, all gases behave like real gases, even gases such as UF6 .
Answer:
particles
Explanation:
hope these help and have a blessed day
Answer: A
Explanation: Beach deposits and wind blown deposits generally show good sorting because the energy of the transporting medium is usually constant.
Assuming that the reaction is unimolecular on both
reactant and product sides such that:
HA + OH-
--> A- + H2O
Therefore the amount of A- left is:
mmol HA = 9.00 - 3.00 = 6.00 <span>
mmol A- = 3.00
pKa = - log Ka = 5.25
</span>
<span>Calculating for pH:
pH = 5.25 + log 3.00/6.00</span>
<span>
pH = 4.95 </span>
