It’s called Diethyl ether so I think the answer is D
Answer:
carbon dioxide CO₂
Explanation:
Each gas has a characteristic boiling point. You can separate a random sample of gases by gradually cooling the sample until each component gas liquifies. Some compounds, such as CO₂ never liquify. Instead, they turn directly into solids.
I don't know if this is multiple choice but if it isn't I can name of few.
Fun Fact: Noble Metals are chemical elements that have outstanding tolerance and resistance to oxidation.
Answer: Palladium, Silver, Platinum, and Gold. Those are all examples of Noble Metals.
Other: Ruthenium, osmium, and rhodium.
<em>Hope this helps!</em>
First, find the number of moles for each element. The molar
mass for nitrogen is 14 g/mol and that of hydrogen is 1 g/mol.
1.40 g N / 14 g/mol = 0.1 mol N
0.20 g H / 1 g/mol = 0.2 mol H
Find the mole ratio. Divide both numbers with the much lower
value. In this case, it is 0.1 mol N.
For N: 0.1 ÷ 0.1 = 1
For H: 0.2÷0.1 = 2
Thus, the empirical formula is 
.
Its has 24 protons, 24 electrons, and 28 nuetrons
