A student reacts Mg and HCl together. The product of this reaction is H, gas and MgCl2. The balanced equation for this reaction is
Mg + 2HCI - H2 + MgCl2
If I need to create 50 L of Hy, how many moles of HCI should I start with?
a) 2.3 mol HCI
b) 4.5 mol HCI
c) 1.1 mol HCI
d) 44.6 mol HCI

Oxygen= 88ghydrogen= 12g

Pretty sure it's d. heterogeneous is separated by physical properties. 

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. polyethylene is a plastic material called thermoplastic. one very useful property of thermoplastic is that when it is heated it turns into liquid, which can be molded into desired shape and size. also the material do not dissolve at room temperature.
