Answer:
A)The total number of protons plus neutrons= Weight of an atom
The answer is A.) because each carbon atom has six electrons meaning that there are six protons.
Answer is: <span>an atomic radius.
</span>The atomic radius<span> of a </span>chemical element<span> is a measure of the size of its atom.
</span>The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.
The atomic radius decreases across the periods because an increasing number of protons, because <span>greater attraction between the protons and electrons.</span>
Answer:
7.506 g
Explanation:
In order to answer the first question we need to keep in mind the requested concentration of acetate: 0.250 M. With the concentration and the volume we can calculate the required moles and then the required grams:
0.250 M * 0.500 L = 0.125 moles acetate
0.125 moles * 60.05 g/mol = 7.506 g
So 7.506 g of acetic acid will be needed to prepare the buffer.
Answer:
The two enzymes are Superoxide dismutase and glutathione peroxidase.
Explanation:
2O2+2H+ = H2O2+02
The above reaction is catalyzed by superoxide dismutase which deals with the conversion of superoxide into hydrogen peroxide(H2O2).
H2O2 + 2GSH = 2H2O + GS-SG
The above reaction is catalyzed by glutathione peroxidase in which the reduced glutathione reacts with hydrogen peroxide(H2O2) to form H2O by reduction and oxidized glutathione by oxidation.The above reaction is a redox reaction which mean in this reaction both oxidation and reduction taking place simultaneously.The reaction occur to minimize the toxic effect of H2O2.
