PLEASE HELP A 3.81-gram sample of NaHCO3 was completely decomposed in an experiment.
2NaHCO3 - Na2CO3 + H2CO3
In this experiment, carbon dioxide and water vapors combine to form H2CO3. After
decomposition, the Nazco, had a mass of 2.86 grams.
A. Determine the mass of the H2CO3 produced.
B. Cáiculate the percentage yield of H, Co, for the reaction. Show your work or describe the
calculation process in detail.

Which of the following is always a reactant in a combustion reaction? oxygen nitrogen hydrogen carbon

Stage in which a typical star has completely stopped fusion

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
