The formula for hyposulfurous acid is H2SO2.
Answer:
hope it is use full to you
Explanation:
The gas constant is denoted by the symbol R or R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure–volume product, rather than energy per temperature increment per particle.
it is a physical constant that is featured in many fundamental equations in the physical sciences, such as the ideal gas law, the Arrhenius equation, and the Nernst equation. As a consequence, the value of the gas constant is also exactly defined.
Answer: 0.0195g of CO2 is produced
Explanation:
CH4 + 2O2 —> CO2 + 2H2O
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
From the equation,
16g of CH4 produce 44g of CO2.
Therefore 7.10×10^−3 of CH4 will produce Xg of CO2 i.e
Xg of CO2 = (7.10×10^−3x44) /16 = 0.0195g

The atomic mass of Ag is 107.87. The atomic mass of Cl is 35.45. The molecular mass of AgCl is therefore 143.32. 0.025 mols of AgCl were produced. This required .0125 mols of the original metal chloride since it has 2 chlorine atoms per molecule and AgCl only has one per molecule.
The molecular mass of mCl2 must be 127.2 in order for 1.59g of mCl2 to be .0125 mols. The molecular mass of m can be calculated by subtracting the molecular mass of 2 chlorine atoms
127.2-35.45-35.45=56.30</span>
