Answer:
CARBOHYDRATES AND CARBOHYDRATE METABOLISM
N(C)=5,02·10²² atoms
calculation check:
N(C)=(1/12)*6.022*10²³=0.5018*10²³≈5.02·10²²
A) Ca(OH)2 + CO2 —> CaCO3 + H2O
B) when Ca(OH)2 is reacted with CO2, the CaCO3 produced is a precipitate which turns the solution milky
Colligative properties include lowering the freezing point, lowering the vapor pressure, and raising the boiling point.
The state of matter of Polaris, the north star is gas.
<h3>What are stars made of?</h3>
Stars are made up of a mixture of hot gases.
The mixture consists of helium and hydrogen. Hydrogen burns into helium to give starts a shining appearance when observed from a far distance.
Thus, the state of matter of all stars, including the north star, is gas.
