25/2 and 96/X
CROSS MULTIPLY.
2x=2,400.
divide by 2.
x=1,200.
you take the GIVEN MASS of an element, and you put it on top, the coefficient is what it’s over. i believe this is right
Answer is: increase the concentration of NiCO₄ and <span>withdraw CO from the products as it is forming.
Balanced chemical reaction: NiCO</span>₄(g) ⇄ Ni(s) + 4CO(g).
According to Le Chatelier's Principle the position of equilibrium
moves to counteract the change:
1) the position of equilibrium will move to the right, so
that the concentration of nickel carbonyl gas decreases again and produce more nickel.
2) the position of equilibrium will move to the right, if we decrease concentration of carbon monoxide, more nickel carbonyl gas will decompose and produce more nickel.
If a runner completes a 10 km race in 32.5 minutes, his pace or speed can be calculated by the equation:
velocity = distance/time = 10km/32.5 mins = 0.3125 km/min
Convert this value to miles per hour using the conversion factors for minutes to hours and kilometers to miles as requested by the problem. This gives an answer of 11.47 miles per hour.
0.3125 km/min x 60 mins./ 1 hour x 1 mile / 1.609 km = 11.47 miles/hour
<span>FIXATION.In the nitrogen cycle, nitrogen is converted into many chemical forms through biological and physical processes like nitrogen fixation, ammonification, nitrification and denitrification.During ammonification, ammonium ions are released after decomposition of plants.During nitrogen fixation, nitrogen gas is changed to nitrates by nitrogen fixing bacteria in the soil.These are used by vegetation.</span>
