Answer:
95.2 - 40.8 = 54.4 g of oxygen
number of moles = mass (g)/ Mr
no. of moles of carbon = 40.8/12 = 3.4
no. of moles of oxygen = 3.4
divide both by smallest value which is 3.4 and you’ll get 1 mole of carbon and 1 mole of oxygen therefore the empirical formula is CO
Explanation:
hope this helps :)
a. The mass is greater before the change occurs.
A because the end result of this reaction is a radical created by the oxidation of an aromatic amine's or phenol's ring substituent. The hydroxyl group of a phenol acts as the ring substituent in this situation.
<h3>Which two enzyme types are required for the two-step process of converting cytosine to 5 hmC?</h3>
- The methyl group is transferred to cytosine in the first stage, and it is then hydroxylated in the second step.
- Therefore, a transferase and an oxidoreductase are the two groups of enzymes required.
<h3>Which kind of interaction between proteins and the dextran column material is most likely to take place?</h3>
- Hydrogen bonding because the glucose's OH would form an H-bond with any exposed polar side chains on a protein surface.
<h3>Two out of the four proteins would adhere to a cation-exchange column at what buffer pH? </h3>
- Only positively charged proteins can bind to a cation-exchange column, and this can only happen when the pH is lower than the pI.
- Proteins A and B would both be positively charged at pH 7.0.

Answer:
c
Explanation:
because of the law of gravity
<h3><u>Answer</u>;</h3>
= 1.44 L
<h3><u>Explanation</u>;</h3>
Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.
Mathematically;
<em>P α 1/V</em>
<em>PV =constant </em>
<em>Thus, P1V1 = P2V2 </em>
<em>P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm</em>
<em>V2 = P1V1/P2</em>
<em> = (1× 3.6)/2.5 </em>
<em> = </em><u><em>1.44 L</em></u>
