The circulatory system moves blood in our bodies. The blood can move oxygen and nutrients to our muscles and limbs. The heartbeat pushes the blood, and the blood cells carry glucose.
False. Carbon is definitely one of the 92 naturally occurring elements within the periodic table.
Answer:
CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)
Explanation:
The solvay process is an important process in the chemical industry. In this process, ammonia gas is first dissolved in concentrated brine to form a mixture known as ammoniacal brine. This solution is made to trickle down the tower. A counter stream of carbon dioxide is forced up the tower. The two substances react to form sodium hydrogen trioxocarbonate IV. This substance is only slightly soluble and separates out as a solid sludge. The product is now dried and heated to give sodium trioxocarbonate IV.
The overall reaction of the process can be given as;
CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)
Calcium chloride is merely a by-product.
Answer:
a) 0.15
Explanation:
A concentração de sacarose é 0,15 g / l no etanol. O Brasil está produzindo etanol em grandes quantidades que é usado como combustível em veículos e indústrias. Este etanol é produzido a partir da cultura da cana-de-açúcar e o Brasil é o segundo maior produtor mundial com cerca de 34,45 bilhões de litros em 2019. Os Estados Unidos da América e o Brasil produzem cerca de 84% do etanol mundial.
