Answer:
calcium to give calcium oxide to give calcium trioxocabonate (limestone) to give carbondioxide
It will depend on the chemical, if it's a chemical compound, yes it can be decomposed chemically into simpler substances, further elements that constitute or make up the given compound.
Mixtures are separated by physical means as there are still separate entities as the substances required to make the mixture do not chemically combine or become altered chemically.
Elements cannot be decomposed into simpler substances as the simplest substance of matter is an element itself. This cannot be decomposed by chemical means.
Answer:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Explanation:
Pressure of the wet gas = 
1 atm = 760 Torr
Pressure of water vapor = p = 0.0372 atm
Pressure of gas = 
Volume of wet gas = 
1 mL = 0.001 L
Temperature of the wet gas = 
Pressure of dry gas at STP = 
Temperature of the dry gas at STP ,
Volume of dry gas at STP = 
Using combined gas law:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1".
In general it is known that nonmetals are very poor
conductors of heat and electricity. The nonmetals that are solid are normally
very brittle and has very little or no metallic luster at all. Nonmetals are
highly reactive and show variety of chemical properties. It can also be pointed
out that the nonmetals gain electrons very easily.
