#8 would be radiation
Because of the heat it produces for the air in the home
#9 Conduction
Because it’s preventing physical heat transfer
#10 convection
Because it is stopping the air from rising
#11 Radiation
Because the heat is emitting from the stove and warms him, but not by direct contact
#12 Conduction
Because the heat transfers from the top of the stove to the cats fur.
#13 Conduction
Because the stove under it heats it through contact
#14 I think Radiation
Because the heat warms up the dish through the air in the oven
#15 Radiation
Because the heat is emitting from the fire.
#16 Conduction
Because the blanket is warming you through physical contact.

I’m not completely sure but the is the best I got. Good luck!

For the following question, select the correct chemical formula for the elements if they were to bong together.
9966 [12]

Answer:

Ionic

Explanation:

Lithium is an alkali metal and form an ionic bond by donating an electron.

Fluorine is a halogen and forms ionic bonds by accepting an electron.

The electronegativity difference between lithium (0.98) and fluorine (3.98) is 3 Pauling units. Usually, when elements have a difference of 1.7 (or 2.0) Pauling units the bond is classified as ionic.

Hope this helps! If you have any more questions or need more explanation please leave a comment down below and I will reply ASAP. Good luck!

Calculate the enthalpy change for the reaction 2 hcl → h2 + cl2 1. +184 kj/mol of rxn 2. +428 kj/mol of rxn 3. 0 kj/mol of rxn 4
lesantik [10]
Below is the list of enthalpies of formation of the compounds involved in the chemical reaction.

HCl: -92.3 kJ/mol
H2: 0 
Cl2: 0

Both H2 and Cl2 do not have enthaply of formation because they are pure substances. 

Since, in the reaction there are 2 moles of HCl,
   Enthalphy of formation = enthalpy of products - enthalphy of reactant/s
                = 0 - (-92.3)(2) = +184.6 kJ

Hence, the answer is the first choice.

The last intermediate in citric acid cycle is:_________
GenaCL600 [577]

The last intermediate in citric acid cycle is Oxaloacetic acid.

<h3>What is Citric Acid Cycle?</h3>

Organic molecule HOC(CO2H)(CH2CO2H)2 is the chemical formula for citric acid. It is a weak organic acid that is colorless. Citrus fruits naturally contain it. It is a biochemical intermediary in the citric acid cycle, which is a component of all aerobic organisms' metabolism.

Every year, more than two million tons of citric acid are produced. It is frequently used as a flavoring, an acidifier, and a chelating agent.

Citrates, which include salts, esters, and the polyatomic anion present in solution, are derivatives of citric acid. Trisodium citrate is an example of the former; triethyl citrate is an example of an ester.
