The question is in complete, complete question is :
Balance each of the following chemical equations. (Use the lowest possible coefficients for all reactions.
a)
b)
c)
d)
e)
Answer:
Explanation:
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side or total number of all atoms of each elements on reactant sides are equal to the total number of all atoms of each element on product side
a)
b)
c)
d)
e)
Answer:
a) 12/323
b) 8/233
Explanation:
a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323
b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233

Answer:
Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades, and improved operation and maintenance. On a global level, energy use can also be reduced by the stabilization of population growth.
Energy conservation is the key element of this policy because of its potential to reduce overall energy demand, costs, and consumption. ... It is often the most economical strategy to advance climate protection efforts and provides an environmentally safe alternative to increased energy production and consumption.
