8. Una forma de separar una mezcla de aserrín y agua es por medio de la filtración, como se muestra en la figura. * ¿Qué característica de la malla permite la separación de la mezcla? Su peso. El tamaño de sus agujeros. El color de su material. Su área. su área es ciencia naturales gracias no crean lo que mando de su area porque no aparece ciencia naturales

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
