Answer:
THE AMOUNT OF HEAT ABSORBED DURING THE REACTION IS 151.64 JOULES
Explanation:
Mass = 12.58 g
Specific heat of CaCO3 = 0.82 J/g K
Change in temperature = 38.3 C - 23.6 C = 14.7 C
How many joules of heat are absorbed?
Heat of a reaction is the amount of heat absorbed or evolved when a gram of a sample is raised by 1 C.
Heat = mass * specific heat * change in temperature
Heat = 12.58 * 0.82 * 14.7
Heat = 151.64 J
The amount of joules absorbed during this reaction is 151.64 J.

What determines the solvent that is the upper and the one that is the lower is density
2
The distribution is in this manner neutral organic product would move to organic layer while charge product would go to aqueous layer and then for the inorganic by-product it would move to the aqueous layer
Explanation:
Looking at question one, to further explain when a solvent has a greater density than the solution it stays at the lower layer while the one with a lower density would stay above it
Method One of Three:
Identifying the Proper Waste Disposal Method
Read the material safety data sheet.
chemical products come with disposal instructions right on the label and following those instructions should be enough. Even for products without disposal instructions, you should still read the labels so you can be aware of the warnings and cautions concerning said products.
Items such as batteries and light bulbs have to be recycled at special recycling centers.
Never mix cleaning products together. If you only have a small amount of cleaning product left in each bottle, it may be tempting to mix them into one bottle for disposal. Different chemicals can react with each other to form very hazardous fumes and noxious gases.
Search the list of hazardous waste
In addition to the product label, you want to read the MSDS for industrial chemicals. The MSDS gives you important information about the chemical: its toxicity, reactivity, and disposal considerations.
Every chemical product you buy should come with an MSDS sheet. However, you can also use the online MSDS database to look up the MSDS for the specific formulation of the chemical you wish to dispose.[1]

Sorry that’s all I know :)
Answer:
igneous rocks are made from molten,and therefore rarely have fossils in them.Metamorphic rocks are squished,put under pressure,and get heated to the extreme,so it's very rare for fossils to survive in these conditions.
