Should existing structures build from CCA-treated wood be removed?

Arturiano [62]

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.

which components of an endothermic reaction have a higher heat content?-reactants-products-reaction vessel-water

lana66690 [7]

Please, observe that it is not right to say that a substance content heat.

Heat is not something that a body or substance content. Heat is the transmission of energy due to difference of temperatures.

An endothermic reactions is that where the reactants abosorb energy from the surroundings to occur. The products, then, will be higher in energy than the reactants while the surroundings get colder.

On the space shuttle, lithium hydroxide is produced from lithium oxide and water. The lithium hydroxide then reacts with the exh

Ratling [72]

Answer:

6,2g of CO₂

Explanation:

Based on the reactions:

Li₂O(s) + H₂O(g) → 2LiOH(s)

LiOH(s) + CO₂(g) → LiHCO₃(s)

2,6g of Li₂O and 1,3g of H₂O are:

2,6g × ( 1mol / 29,88g) = 0,087 moles

1.3g × ( 1mol / 18,01g) = 0,072 moles

That means limiting reactant is H₂O. The moles produced of LiOH are:

0,072 moles of H₂O × ( 2mol LiOH / 1mol H₂O) = 0,14 moles of LiOH

Thus, the maximum CO₂ that can react are 0,14 moles of CO₂, in grams

0,14 moles CO₂ × (44,01g / 1mol) = 6,2g of CO₂

I hope it helps!
