Yes magnesium is a pure substance and it is a element.
The number of moles present in the FeSO4 are 0.055 mol.
<u>Explanation:</u>
- The mass of a substance containing the same number atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to 6.023 x 10^23. The moles of a substance can be determined by using the formula,
Number of moles = mass in grams / molecular mass
Given,
mass = 8.36 g,
molecular mass of FeSO4 = 151.908 g / mol
number of moles = 8.36 / 151.908
= 0.055 mol.
If temperature were to double the pressure would likewise double. Increased temperature would increase the energy of the molecules and the number of collisions would also increase causing the increase in pressure.
Answer: the product is ketone or aldehyde
Explanation:
The first step is the conversion of acetal to hemiacetal in the presence of H3O+/ ROH, and then the final conversion of hemiacetal to ketone/aldehyde using
H3O+/ ROH...
