We have a 100ml one molar agno3 solution. which of the following would make the lamp light much higher?
1)0.02mol nano3
2)0.03mol nacl
3)0.02mol bacl2
4)0.03mol mg3(po4)2
why? description to me.

What is the molar mass of a gas that has density of 2.054 g/l

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
