Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
This is a strong base / week acid reaction.
NaOH + CH3COOH
The equilibrium of this reaction is very displaced to the right leading to the formation of the products
Na CH3COO + H2O
Na CH3COOH is a ionic compound which in solutionn will be as Na (+) and CH3COOH(-)
=> CH3COOH + NaOH = CH3 COO(-) + Na(+) + H2O
So, the predominant species in the solution are the ions Na(+) and CH3COO(-).
In general, in an strong base / weak acid titration, the predominant species present at the stoichiometric point will be the cation of the strong base (Na+ in this case) and the conjugate base of the weak acid (the anion of the weak acid, which is CH3COO- in this case).
The answer is predominantly Na(+) and CH3COO(-); predominantly because it is an equlibrium which means that the rectants will also br present.
Cells need ribosomes to make protein.
Answer:
THE hard-water effect is a recognized source of error in radiocarbon dating. It causes ages to be over-assessed and arises when the material to be dated, such as mollusc shell or plant, synthesizes its skeleton under water and so uses bicarbonate derived in part from old, inert sources.
