SHCHCHOH
What is the pH of 0.0012 M NaOH (aq)?
Provide a term for each description
- A pair of electrons shared between two atoms
- Type of compound formed by electrons being shared between two atoms
When 4.00 g of sodium hydrogen carbonate reacts completely with 90.0 mL of
acetic acid, the temperature increases from 20.00 ºC to 40.00 ºC. The products are
carbon dioxide, water and sodium acetate. Calculate the molar enthalpy of reaction,
ΔHrxn. Include a balanced thermochemical reaction.
The stability of metal carbonyl complexes falls off markedly as we go to the right of group 10 in the periodic table. For example, Cu complexes only bind CO weakly. Why is this? What oxidation state, of the ones commonly available to copper, would you expect to bind CO most strongly?
If one mole of any substance contains 6.022 x 1023 particles, does one mole of monoatomic oxygen (O) contain the same number of atoms as one mole of diatomic oxygen (O2)?
Explain why an atom in the 4th period is larger than the 3rd period.
Can you name any substance which is a mixture of two monovalent alkalies (preferably metal hydroxides) in the ratio 1:3, which can be used to neutralize aqua regia as it is a mixture of two monovalent acids in the ratio 1:3 as you have said, since aqua regia is a mixture of two concentrated acids, this substance shall be a mixture of two concentrated alkalies and as you said, the pH of this mixture should be almost near to 14 which should mean that it will be highly alkaline, also name the complex cation (with valence) formed in that case, and which one will act as the reducer in that mixture, you shall also tell the endpoint in it
Give the Hybridization for all the atoms in the molecule SHCHCHOH
My question is the following:
"Low-oxidation-state complexes are often air sensitive (i.e., they react with the oxygen in the air) but are rarely water sensitive. Why do you think this is so?"
