Answer:
cupro - nickel
if u on its weight its 9.00gms and diameter:23mm
Answer & Explanation:
The law of multiple proportion states that two elements A and B can react with each other to form multiple compounds while one of the two elements remain fixed.
For Example
Hydrogen reacts with oxygen to form:
Water (H2O)
Hydrogen peroxide (H2O2)
Answer:

Explanation:
Lisoprisil's molecular mass is 405.488g/mol, we'll use this fact to calculate molarity, which units are mol/L, and we proceed to the calculus:
- First, we'll unify unities, the 10 milligrams of lisinopril we'll transform into grams.

- Now that we have the same unities we'll calculate molarity using the molecular mass, the grams of lisinopril and the liters in which these grams are, let's consider that our final unities have to be mol/L.

I hope you find this information useful and interesting! Good luck!
Answer:
Decrease temperature with increase in ammonium nitrate concentration.
Explanation:
The temperature changes when different masses of ammonium nitrate are dissolved in water because the ammonium nitrate takes energy from the surrounding water environment for the breaking of ionic bonds as a result the temperature of water decreases. When more concentration of ammonium nitrate is added to water, more decrease occur in temperature of water and the water becomes cold.
Chemical reaction, generally speaking. It's a vague definition, but it's easy to remember.
