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:
that is all I know sorry hope that may help you :)
Explanation:
Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :
*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue
* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.
Answer:
C. its particles move farther apart and the substance becomes a gas.
Explanation:
A. is wrong because moving closer together creates a solid, not a gas.
B. is wrong because moving father apart creates a gas, not solid.
C. is correct because moving farther apart creates a gas.
D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.
- Just know the states of matter and how the particles move and that will help with this problem.
