Answer:
58.8%
Explanation:
n= Experimental/Theoretical ·100
n= 5.50/(your answer to part A) 9.36·100 = 58.8%
B= CH2O
empirical formula using the simplest ratio of atoms in the compound
Answer:
B. convection because warm air rises and cool air sinks.
Explanation:
The processes that enables birds to fly to higher altitudes without flapping their winds while riding air thermals is called convection.
Convection is one of the forms of heat transfer usually found in gases and liquids.
- In convection density differences due to temperature changes causes the circulation.
- Warm air is less dense and it is hotter.
- It rises up from the surface where it is warmed
- Cold air sinks to replace the warm air. Cold air form when the air loses its energy to the surrounding.
- By virtue of this, birds are able to take advantage of it for their flight.
Gold is known to be an element. The term that best describes 10-karat gold is that it is an homogeneous mixture.
- Gold as an element of often has an ideal state of purity where there contains nothing but gold atoms.
A heterogeneous mixture is known to be a mixture that cannot be chemically sound everytime. Gold jewelry is known to be a homogeneous mixture as it is always will look good and remain unchanged for a long time.
As good example of homogeneous products, e.g a 1-kilogram 24-karat gold bar has unique properties.
