Answer:
14g
Explanation:
assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles
then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass
so, 0.5 x 28 = 14g
So for that one I’m going to go with True
Explanation:
Mg(s) + Cr(C2H3O2)3 (aq)
Overall, balanced molecular equation
Mg(s) + Cr(C2H3O2)3(aq) --> Mg(C2H3O2)3(aq) + Cr(s)
To identify if an element has been reduced or oxidized, the oxidation number is observed in both the reactant and product phase.
An increase in oxidation number denotes that the element has been oxidized.
A decrease in oxidation number denotes that the element has been reduced.
Oxidation number of Mg:
Reactant - 0
Product - +3
Oxidation number of Cr:
Reactant - +3
Product - 0
Note: C2H3O2 is actually acetate ion; CH3COO- The oxidatioon number of C, H and O do not change.
Oxidized : Mg
Reduced : Cr
Well in my experience with Solar Eclipses is that before it starts or before it is covering the moon is covering the sun there is like a shadow on one side of the sun and after the hours or minutes go by all around you everything is getting darker and a little colder than it was a few moments ago so what it would look like is something is in front of the sun or its like the moon got so close to the sun that it just blocked it and also some of the sun's rays surround the moon.<span />
A metallic bond since both are pure metals but are not ionic
