Answer:
The answer to your question is: density = 0.993 g/ml
Explanation:
Data
mass beaker empty = 29.3 g
volume of liquid = 15 ml
mass beaker + liquid = 44.2 g
Formula
density = mass / volume
Process
mass of liquid = 44.2 - 29.3
= 14.9 g
density = 14.9 / 15
= 0.993 g/ml
They have protons that are identical...
Answer:
A. 1350
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
Ca, they only have two valence electrons, in order to become more stable, they would like to lose all of them
Hey there!
The best way to balance chemical equations is to first start by balancing polyatomic ions such as OH and SO₄.
Next, balance other elements, but save elements that are by themselves for last, such as H₂ or Fe. Once you balance everything else you can do the ones by themselves, it's much easier.
Hope this helps!
