Lithium i believe is the answer
<span>2.40 - 1.68 =0.72 g of oxigen
moles = 0.72/16 g/mol=0.045
moles x = 1.68/ 55.9=0.03
0.03/0.03 = 1 = x
0.045 / 0.03 = 1.5 = O
to get whole numbers multiply by 2
x2O3
X2O3 +3 CO = 2 X + 3 CO2</span>
Answer:
Melting: solid liquid, Freezing: liquid to solid, Evaporation: liquid to gas.
Explanation:
mark me the brainliest
Mg is an element that stands for Magnesium.
Mg is the chemical symbol for Magnesium.
Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.
The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.
Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.
Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.
