Why is galvanized steel preferred for outdoor uses?

1 answer:

Galvanized steel is preferred for outdoor uses because it is ideal to prevent rotting/corrosion A steel will rot more quickly if it's exposed to a larger amount of oxygen and H2O , which will exist if we put it oudoor Coating the steel with additional zinc will slow down the process

What is the empirical formula of a compound that is made of 3.80g of phosphorus and 0.371g of hydrogen?

lys-0071 [83]

You start by diving each quantity given by the atomic wight of each element:

Phosphorus (P) $\frac{3.8}{31} =0.123$

Hydrogen (H) $\frac{0.371}{1} =0.371$

Then you divide by the lowest number:

$\frac{0.123}{0.123} = 1$ for phosphorus

$\frac{0.371}{0.123} = 3$ for hydrogen

So the empirical formula will be:

$PH_{3}$

Mass defect is associated with: nuclear fusion nuclear fission radioactive decay mass lost by nuclear collisions

Kay [80]

I would say mass lost by nuclear collisions. The mass defect is the mass difference between the mass of an atomic nucleus and the sum of the mass of its constituent particles. It equals the energy given off in the formation of the nucleus.
