Answer: The name of this Hydrate is magnesium sulphate monohydrate.
Explanation:
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
a) If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of = 87.0 g
Mass of = 13.0 g
Step 1 : convert given masses into moles
Moles of =
Moles of =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For =
For =
Hence the empirical formula is
Thus the name is magnesium sulphate monohydrate.
Molar mass Na2SO4 = <span>142.04 g/mol
142.04 g -------------- 6.02x10</span>²³ atoms
?? g ------------------ 7.4x10²³ atoms
142.04 x ( 7.4x10²³) / 6.02x10²³
=> 174.60 g
The answer is: The engine will run inefficiently APEX....
Answer:
Bronze is made of the metals copper and tin.
Explanation:
Bronze is stronger than copper as an outcome of combining that metal with tin or different ores. Bronze is more quickly dissolved and is hence more comfortable to cast. It is also harder than pure metal and considerably extra immune to corrosion.
Pure copper is soft and can be formed into wire or pounded into wanted shapes. If the copper is consequently warmed (tempered), it can be performed soft again. Copper and zinc are blended to create brass, and mixed with tin to produce bronze.
