Hey there!
Magnesium chlorate: Mg(ClO₃)₂
Find molar mass.
Mg: 1 x 24.305 = 24.305
Cl: 2 x 35.453 = 70.906
O: 6 x 16 = 96
------------------------------------
191.211 g/mol
We have 187.54 grams.
187.54 ÷ 191.211 = 0.9808
There are 0.9808 moles in 187.54 grams of magnesium chlorate.
Hope this helps!
Answer:
A ability to decompose
B reactivity
Explanation:
Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water by an electric current.
The ability to decompose and reactivity are chemical properties of a substance.
- Physical properties tells us everything about what a substance is when no change is occurring to its constituents.
- Examples are state of matter, color, odor, taste, texture, hardness e.t.c
I think this one is the organelles.
