Convert atoms to moles then moles to grams
chemical equation
(a) NaOH +HCL --->NaCl +H2O
(b) THE number of moles reacted is = molarity x volume in litres
hence the number of moles of NaOH=(o.201 x 30.5ml)/100ml=0.00613 moles
(C) the number of moles of Hcl that were reacted, from the reaction above the recting ratio of NaOH to HCl is 1:1 thus the moles of HCl is also 0.00613
(D) my of HCl is =moles/volume in litres
that is (0.00613/20) x 1000=0.306M
<span>The answer is a. it causes plants and algae to grow quickly, suffocating organisms in the water. The rapid growth of organisms due to fertilizer runoff leads to a process called eutrophication. When the vegetation dies, the process of decomposition leads to the formation of excessive amounts of carbon dioxide, which in turn suffocates aquatic animals.</span>

(226K − 273.15) × 9/5 + 32 = -52.87°F
A. Bond polarity is directly related to electronegativity difference. The greater the difference in electronegativity the more polar the bond.
<span>b. When two elements are next to one another in the periodic table they have similar electronegativities. Chlorine has a value of 3.0 while bromine has a value of 2.8. These two atoms in Br-Cl would have a nonpolar covalent bond.</span>
