1) gain
(just remember this OIL-Oxidation Is Loss and RIG-Reduction Is Gain)
2) decrease
Leaves (and probably other things as well) that have fallen make the soil richer from decay.
The percentage of dissolved salt in saltwater
is 3.5%. We are given the amount seawater sample. <span>We would just multiply the two values together.
750 g (0.035) = 26.25 g NaCl
26.25 g NaCl ( 1 mol / 59.44 g ) ( 1 mol Na / 1 mol NaCl ) ( 22.99 g / 1 mol ) = 10.15 g Na
Hope this answers the question. Have a nice day.</span>
