Answer: Baking soda
Explanation:
Sodium bicarbonate has a chemical formula of NaHCO3, it is a white precipitate formed when excess carbon dioxide is bubbled through a concentrated solution of sodium hydroxide.
It is used in cooking and serves as baking powder.
Protons and neutrons i think , sorry if i’m wrong.
moles of excess reactant remaining: 0.67 mol CS2
moles of each product formed: 0.33 mol CO2 and 0.67 mol SO2
your coefficients in the chemical equation reveal the molar ratio of the reactants that must be present to give a complete reaction of both reactants. in this case each mole of CS2 requires 3 moles of O2 to form the products given. if you start with equimolar amounts of both reactants then the O2 must be in insufficient supply to completely react with all of the CS2. if only 1 mole of O2 is present, it will be consumed by one third that amount of CS2. all O2 will react. 0.67 mole of CS2 will remain. the CO2 comes from the carbon in CS2, so 0.33 mole of CO2 will be produced. since 2 moles of SO2 are produced for each mole of CO2 produced, then the amount of SO2 produced will be 0.67 mol.
Answer:
German chemist G.E. Stahl
Explanation:
this theory was first articulated in 1697
Metals=Reactivity increases as we move through the elements in the period table from top to bottom, and left to right. Nonmetals=Reactivity increases as we move through the elements in the periodic table, as we move from bottom to the top, and right to left. Since reactivity of nonmetals increases going up the periodic table, oxygen is therefore the most reactive nonmetal in the group. So, the answer is oxygen
