Answer:
The proportion of light transmitted by glazing is specified by the Visible Light Transmittance, which is recorded as either TVw (visible transmittance of the window) or VLT (visible light transmittance). These terms are interchangeable, but in Australia, the Window Energy Rating Scheme uses Tvw in its ratings.
While the VLT/Tvw rating varies between 0 and 1, most double glazed windows rate between 0.3 and 0.7 , which means that between 30% and 70% of the available light passes through the window. The illustration above shows you how the view changes, as the amount of light getting through the window changes.

Answer:
H2SO4(aq) + MgO(s) → H2O(l) + MgSO4(aq)
Explanation:
We must recall that the oxides of metals are bases. These metal oxides can react with dilute acids to yield salt and water.
Bearing that in mind, we want to obtain magnesium sulfate from a metal oxide and dilute acid.
In this case we need magnesium oxide and dilute sulphuric acid. The reaction occurs as follows;
H2SO4(aq) + MgO(s) → H2O(l) + MgSO4(aq)
