The metalloids are on the right side of the periodic table B, Si, Ge, As, Sb, Te, and At. The nonmetals are also on the right side next to the metalloids, there should be a He at the top right of the periodic table and there should be one more nonmetal at the top left of the periodic table that is H. And from the metals they are all on the middle next to the metalloids, starting from Li, Be, Na, and Mg as so on all of those are metals.
Its like regular water, but has 2 hydrogin atom insted of one. hope this helps
<span>In the given chemical equation, 4 moles of nh3 gas react with 5 moles of oxygen to form 6moles of water vapours (h2o). Hence each mole of nh3 contributes to production of 1.5 moles of water vapours.
therefore, the rate of formation of h2o is 1.5*0.5 ms-1, i.e 0.75 moles/sec</span>
Answer:
A.0.51L
B 1.67L
Explanation:
using the formula ;C1V1 =C2V2
15.8×V1=2×4
15.8V1=8
V1=8/15.8
V1=0.51L
apply the same method for B
