Alveoli. I don't know what a nephron is but neurons and synapses are in the brain.
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
Answer:
a.labeling food with an ingredient list to inform consumers
Explanation:
A significant MOE exists compared to developmental toxicity effect levels.
Blood alcohol levels from ABHS approximate consumption of non-alcoholic beverages.
No significant risk of developmental toxicity is expected from ABHS use.
Ethanol-based topical antiseptic hand rubs, commonly referred to as alcohol-based hand sanitizers (ABHS), are routinely used as the standard of care to reduce the presence of viable bacteria on the skin and are an important element of infection control procedures in the healthcare industry.
There are no reported indications of safety concerns associated with the use of these products in the workplace. However, the prevalence of such alcohol-based products in healthcare facilities and safety questions raised by the U.S. FDA led us to assess the potential for developmental toxicity under relevant product-use scenarios.
Estimates from a physiologically based pharmacokinetic modeling approach suggest that occupational use of alcohol-based topical antiseptics in the healthcare industry can generate low, detectable concentrations of ethanol in blood.
This unintended systemic dose probably reflects contributions from both dermal absorption and inhalation of the volatilized product.

D. It is a chemical change because solubility in water of Solid A is different than the solubility in water or both Potassium Iodide and Silver Nitrate
Explanation:
From the given table which summarizes findings about the experiment, we can conclude that It is a chemical change because solubility in water of Solid A is different than the solubility in water of both Potassium Iodide and Silver Nitrate.
- A chemical change is a form of change in which new substances are produced.
- A physical change is one in which the states of matter changes especially the form.
Now we that two soluble substances goes to insoluble product.
- A substance is soluble when they go into solution with a solvent of the same type.
- This change from solubility to insolubility of a compound is a typical chemical change.
- Other forms of changes are just physical changes.
