First find the oxidation states of the various atoms:
<span>in Cr2O2 2- Cr @ +1; In NH3 N @ +3; in CrO3 Cr @ +3, N2 N @ 0 </span>
<span>Note that N gained electrons, ie, was reduced; Cr was oxidized </span>
<span>Now there is a problem, because B has NH4+ which the problem did not, and is not balanced, showing e- in/out </span>
<span>B.NH4+ → N2 </span>
<span>Which of the following is an oxidation half-reaction? </span>
<span>A.Sn 2+ →Sn 4+ + 2e- </span>
<span>Sn lost electrons so it got oxidized</span>
Answer:
The answer should be 1000 kg / m3
I say both equinox because winter solstice has the least amount of sunlight and the summer solstice has the most ampunt of daylight so i said both equinox
Answer:
<h3>A homogeneous blend is a combination wherein the piece is uniform all through the combination. The salt water depicted above is homogeneous in light of the fact that the broke up salt is equitably dispersed all through the whole salt water test. ... The measure of salt in the salt water can shift starting with one example then onto the next.</h3>
