Answer- The correct answer is ammonia.
Explanation- All other compounds that are formed do not have any essence of Nitrogen in it. Whereas, Methane is a compound with carbon and hydrogen as elements while water has hydrogen and oxygen as its elements.
Lastly Hydrogen and chlorine combined together to form hydrochloric acid. Hence the only compound left with nitrogen is ammonia and has nitrogen and hydrogen as its basic elements.
Answer:
Explanation:
A substance with a high specific heat, such as the water in Figure 9, heats up and cools down slowly because a much larger quantity of heat is required to cause its temperature to rise or fall by the same amount. Matter can change from one state to another when thermal energy is absorbed or released.
Answer:
4.1 moles of FeCl₃
Explanation:
The reaction expression is given as shown below:
2Fe + 3Cl₂ → 2FeCl₃
Number of moles of Cl₂ = 6.1moles
So;
We know that from the balanced reaction expression:
3 moles of Cl₂ will produce 2 moles of FeCl₃
Therefore 6.1moles of Cl₂ will produce = 4.1 moles of FeCl₃
The number of moles is 4.1 moles of FeCl₃

There are titantium atoms in the cube.
<h3>
Further Explanation</h3>
This problem involves unit conversion and mole conversion. The steps are:
- Convert the length of the cube from inches to centimeter since the density is given in g/cm³.
- Determine the mass of the cube using the given density.
- Convert the mass of the cube to number of atoms using Avogadro's number.
<u>STEP 1. </u>Converting inches to cm
<u>STEP 2:</u> Determining mass of cube from the density
<u>STEP 3:</u> Converting mass of titanium cube to number of atoms
Since the given values have 3 significant figures, the final answer must be:
