Answer: this is some information in what I search
Explanation:
Stable atoms have a binding energy that is strong enough to hold the protons and neutrons together. ... All elements with atomic numbers greater than 83 are radioisotopes meaning that these elements have unstable nuclei and are radioactive.
The solubility of a sample will decrease when the size of the sample increases.
When the Size of sample is bigger, it means there is more particles that make up that sample so the amount of solvent to dissolve the sample will also be in the greater amount. Thus, when the sample size increases the solubility decrease. We can also say that size of sample and solubility are inversely proportional to each other.
Answer:
yes and only upto 2 electrons and very strongly they hold
Answer:
0.1046M NaOH solution
Explanation:
a. KHP is a salt used as primary standard because allows direct standarization of bases solutions. The reaction of KHP with NaOH is:
KHP + NaOH → H₂O + KP⁻ + Na⁺
<em>As you can see, KHP has 1 acid proton that reacts with NaOH.</em>
<em />
Molar mass of KHP is 204.22g/mol; 0.5527g of KHP contains:
0.5527g KHP × (1mol / 204.22g) = 2.706x10⁻³moles of KHP. As 1 mole of KHP reacts per mole of NaOH, at equivalence point you must add <em>2.706x10⁻³moles of NaOH</em>
<em />
As you spent 25.87mL of the solution, molarity of the solution is:
2.706x10⁻³moles of NaOH / 0.02587L = <em>0.1046M NaOH solution</em>
