To determine which has the greatest mass, we need to find out the molecular mass of each element:
Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol
Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or <u>Uranium.</u><span />
Answer:
Allele
Explanation:
An allele is a variant form of a gene.some gene have a variety of different forms which are located at the same position or gentic locuson a chromosone. human are called diploid organisms becuase they jave two alleles at a each genitic locus with one allele inherited from each parent.
hope this helps you. pls mark me brainliest if you feel this answer is good.
thanks. if do have any question pls ask in the comment section.
Answer:
pH = 5.76
Explanation:
We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:
pH = pKa + log![\frac{[SodiumAcetate]}{[AceticAcid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BSodiumAcetate%5D%7D%7B%5BAceticAcid%5D%7D)
We are already know all the required information, thus we<u> input the data given by the problem</u>:
pH = 4.76 + log(20/2)
And finally <u>calculate the pH</u>:
pH = 5.76
The pH of that acetic acid solution is 5.76.
it is water energy :) this is easy
