The answer to this question would be: ammonia
Chemical decomposition is the breakdown of a compound into smaller compound or element. In this question, the Sodium(Na), Argon (Ar) and Sulfur(S) is elements, not compounds.
An element should not breakable since it was the simplest form.
Ammonia(NH3) is a compound so it should be able to be decomposed.
Answer:
2 atm
Explanation:
Chemical reactions are carried out at a certain rate. Sometimes that rate is quite slow, so we want to speed things up, which is usually used by increasing temperature, increasing pressure or adding a catalyst (a substance that increases the rate without changing itself).
If this is the case, then, when writing a chemical equation, we state these special conditions over a right arrow.
Now let's look at the answers:
- 25°C is a value and unit of temperature
- ∆ is a symbol that denotes change
- 2 atm is a value and unit of pressure (atmosphere is old unit for pressure)
- Pt is a chemical symbol for platinum, an element often used as a catalyst.
So, the correct answer is C) 2 atm
I think it’s most likely a, but it could be D :)
There are titantium atoms in the cube.

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:
