mezya [45]

Answer:

See explanation

Explanation:

The law of conservation of mass states that mass can neither be created nor destroyed. This implies that in a chemical reaction, we can only have the same number of atoms of each element on both sides of the reaction equation.

If we write  4Fe2S3 it means that we have;

4 * 2 = 8 atoms of Fe

4 * 3 = 12 atoms of S

8 + 12 = 20 atoms in all

Should existing structures build from CCA-treated wood be removed?
Arturiano [62]
<span>There are pros and cons as to whether CCA-treated (pressure-treated) wood should be removed from existing structures, and both sides are subjective. Some of the arguments for leaving it include: *When burned, the wood can release dangerous, and sometimes, lethal fumes. *If buried in a landfill, the chemicals can soak into the ground and eventually contaminate ground water. *Removing it can expose people to arsenic *It is costly to remove an existing infrastructure that may or may not be harming people *Studies conducted within the past decade have determined structures containing CCA-treated wood pose no hazard *Studies also concluded that children who played on CCA-treated playgrounds were exposed to arsenic levels lower than those that naturally occur in drinking water Some of the arguments for removing it include: *The EPA determined that some children could face higher cancer risks from exposure to CCA-treated wood *If removed, it will need to be disposed of and, as discussed above, that creates another set of problems that could affect a community's health. A possible solution is to leave existing CCA-treated wood in place but seek viable, safe alternatives for future structures.</span>

Answer:

D

Explanation:

Solar panels are not toxic, so option A goes out the window.

Aesthetics don't really matter, so option B follows it out.

Option C makes a little sense, but less so than Option D. They aren't nearly as heavy as some of our current energy production methods.

Solar panels are expensive,  hard to store properly, and most are between 15 and 20 percent efficiency, compared with a diesel motor's 40 percent.

If 4.50 g of (nh4)2so4 is dissolved in enough water to form 250. ml of solution, what is the molarity of the solution?
natima [27]
The molarity of a solution is the number of moles of a substance in one liter of that substance. 
The molar mass of ammonium sulfate (NH4)2SO4 is 132.14 grams/mole
Calculate the moles of ammonium sulfate:
(4.50 grams)/(132.14 grams/mole) = 0.0341 moles of ammonium sulfate
convert mL to Liters 250. mL becomes 0.250 liters
Take the number of moles over the number of liters
0.0341 moles / 0.250 liters = 0.136 molar or 0.136M = molarity of the solution
