Answer:
Empirical formula of 81.8 carbon and 18.2 hydrogen
Steps
- Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
- Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>
Answer:
45/9 or 5
Explanation:
the oil which relative amount is greater than demand is fuel oil, whose fraction is 45/9
When salt is added to ice , it comes into contact with the thin layer of water on the surface of the melting ice. ... This salt water has a lower freezing point, so the temperature of the ice bath can get even colder, thus freezing the ice cream more quickly.

B. the crystals have abundant room to grow in their hollow surroundings
Explanation:
Minerals in geodes form spectacular euhedral crystals because the crystals have abundant room to grow in their hollow surroundings.
Euhedral crystals are crystals that have well formed and defined faces. The opposite term for euhedral is anhedral. Anhedral crystals lacks crystal faces.
When a crystal have abundant room to grow in their hollow surroundings, they grow and develop well without any alteration of their faces.
Crystal faces are destroyed when crystals don't have spaces to grow and they touch each other.
