Hey!
I would say the answer is A. Plow the soil many times to lessen the chance of the topsoil being blown away.
Hope this helps !
Answer:
Molarity of HCl = 1.6M
Explanation:
The chemical reaction equation is;
HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)
Now, molarity = number of moles/volume
Thus, for NaOH, we have;
Number of moles = molarity × volume = 2M × (20/1000) L
Number of moles = 0.04 moles
Using the coefficients in the chemical equation above, we can find the corresponding number of moles for HCl.
Number of moles of HCl = 0.04 moles NaOH × (1 mole of HCl/1 mole of HCl) = 0.04 moles of HCl
Thus;
Molarity of HCl = 0.04/(25/1000)
Molarity of HCl = 1.6M
Answer:
c
Explanation:
the way you move explains how confident you are
Proton and neutron because e does not matter much
and the mass of atom as you already know is consist of p and n
I would go with option #4, reduced use of resources!
