Water is an example of a Polar Molecule. Your answer is A
Answer:
You make aluminum phosphate which is an insoluble salt, so a precipitated is formed.
Explanation:
First reagent: Al(NO₃)₃
Second reagent: (NH₄)₃PO₄
This is the reaction:
Al(NO₃)₃ (aq) + (NH₄)₃PO₄ (aq) → AlPO₄ (s) ↓ + NH₄NO₃ (aq)
Al³⁺ (aq) + PO₄⁻³ (aq) ⇄ AlPO₄ (s) ↓ Kps
Salt from phosphate is formed.
Answer: False
Explanation: The chemical hazard label indicates the class of harzard of chemical products. It appears on their Safety Data Sheet (SDS), which contains a lot of informations about these substances.
The chemical hazard label is divided into four colors and which one has a meaning (categorie) connected with a number, like:
Blue: Health hazard - If the chemical is deadly (4), extreme danger (3), hazardous (2), slightly hazardous (1) or a normal material (0).
Red: Fire hazard (flammability) - If the chemical has flash point bellow 73ºF (4), bellow 100ºF (3), above 100ºF not exceeding 200ºF (2), above 200ºF (1) or will not burn (0).
Yellow: Reactivity (it can be related to instability) - If the chemical may detonate (4), shock and heat may detonete it (3), if it can suffer a violent chemical change (2) or unstable if heated (1) or if it is stable (0).
White: Specific hazard - If the chemical is acid (ACID) or alkali (ALK), for example.
Answer:
a. Molarity= 
b. Molality= 
Explanation:
Hello,
In this case, given the information about the aniline, whose molar mass is 93g/mol, one could assume the volume of the solution is just 200 mL (0.200 L) as no volume change is observed when mixing, therefore, the molarity results:
Moreover, the molality:
Best regards.
Answer:
FBr is a chemical formula representing "flourine monobromide."
Explanation:
Of course, FBR could represent a number of things, from the Federal Board of Revenue to a fluidized bed reactor. I gave the answer I did because you listed this question as Chemisty.
