Answer:
5.42 mol
Explanation:
To find moles, divide the given mass by the compounds molar mass. To find the molar mass of the compound, add of the masses of each individual component:
Molar mass of NaNCO3 = Na + N + C + (O x 3)
Molar mass of NaNCO3 = 23 + 14 + 12 + (16 x 3)
Molar mass of NaNCO3 = 97 g/mol
Moles = mass / molar mass
Moles = 526 g / 97 g/mol
Moles = 5.42 mol
i believe the answer is A. chemical formula
Answer:
I hope you are happy .....keep practicing
The balanced chemical reaction would be as follows:
CH4 + O2 = CO2 + 2H2O
We are given the amount of CO2 product in the reaction. This will be the starting point for the calculations. We do as follows:
5.6 L CO2 ( 1 mol / 22.4L ) ( 1 mol CH4 / 1 mol CO2 ) ( 16.05 g / 1 mol ) = 4.01 g CH4 needed

Explanation:
Chemical reactions are an integral part of technology, of culture, and indeed of life itself. Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years. Chemical reactions abound in the geology of Earth, in the atmosphere and oceans, and in a vast array of complicated processes that occur in all living systems.
