Answer:

Magnesium Sulfite

Explanation:

Magnesium sulfite is a salt of sulphurous acid. Magnesium sulfite usually occur in an hydrate state instead of the anhydrous Magnesium Sulfide which has four oxygen.

The hydrated state usually attaches 6 molecules of water but when heated could lose some molecules of water to become a tri-hydrate salt.

How many moles of water are created if 3 moles of hydrogen react completely with excess oxygen?

Alenkinab [10]

Answer:

3.0 moles.

Explanation:

It is a stichiometry problem.

The chemical reaction of reacting hydrogen with oxygen to produce water is:

H₂ + 1/2 O₂ → H₂O.

It is clear that 1.0 mole of H₂ reacts with 0.5 mole of O₂ to produce 1.0 mole of water.

The ratio of the reacting hydrogen to the produced water is 1:1.

∴ The number of moles of water created from reacting 3.0 moles of hydrogen completely with excess oxygen = 3.0 moles.

Devise a temperature scale, abbreviated g, for which the magnitude of the ideal gas constant is 1.00 j g–1 mol–1 .

melisa1 [442]

The value of ideal gas constant (R) in Joule is 8.314 Joule $Kelvin^{-1}$ $mol^{-1}$ . Now the given expression is 1.00 J. g $g^{-1}.mole^{-1}$ . Where the g represent the temperature. Thus the abbreviated g must have the value 8.314 to satisfy the original value. Thus the temperature scale will be 1 kelvin = 8.314 g. Now 1 kelvin = -272.15°C or in terms of abbreviation of g we can write -272.15 °C = 8.314g, or, 1°C = (-) $\frac{8.314}{272.15}=0.030$ g. Thus the temperature scale of the g scale is 1 kelvin (K) = 8.314g and 1°C = 0.030 g.
