What else can I help you with?
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
How do you know when there is No Reaction in a chemical reaction?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion - possible chemiluminescence - formation of new compounds
What is color and formula of the precipitate?
A precipitate is a solid that is formed when mixing two solutions. The dissolved ions or molecules from the two solutions mix and form a new compound which is no longer soluble, and so a solid forms. The identity and composition of the solid depends completely on what two solutions have been mixed together. Without knowing what is being mixed, you cannot know what the composition of the precipitate is.
When given the double displacement reaction below which of the products would be soluble in water and which would likely form a solid precipitate How do you know?
You didn't show a reaction. The way you would know is by studying/memorizing or looking up the SOLUBILITY RULES.
What is a mutation you might have but not know about?
substitution

How do you know if a precipitation reaction has occurred?
A precipitation reaction occurs when two aqueous ionic compounds react to form an insoluble solid called a precipitate. You can detect a precipitation reaction by observing the formation of a cloudy or milky solution, or by the appearance of a solid at the bottom of the reaction vessel.

How do you know which compound it is by adding silver nitrate?
For example, adding silver nitrate solution to a solution containing halogen ions: formation of a white insoluble precipitate.
If siler nitrate was added to potassium chloride how would you know that the residue was potassium chloride?
The reaction is: AgNO3 + KCl = AgCl + KNO3The precipitate is silver chloride.
How do you know that a new substance is form from a reaction?
Some indicators are: - an increase of temperature - release of a gas - change of color - change of odor - formation of a precipitate etc.
What is a mutation you might have but not know about?
substitution
A solution containing 14 grams of AgNo3 is added to a solution containing 4.83 g of CaCl2. Find the mass of the precipitate produced.?
Ok, lets begin by writing out the reaction : 2AgNO3 +CaCl2 --> 2AgCl(s) + Ca(NO3)2 Precipitate = AgCl Now find the mol of compound in each solution: 14g AgNO3 x (mol/170g) = .082mol 4.83g CaCl2 x (mol/111g) = .044mol Determine limiting reactant: Notice in reaction that 2 CaCl2 molecules react with 1 AgNO3. Because 2(.044mol) > 1(.082mol), AgNO3 is your limiting reactant. Now that you know this you can find the mass of the precipitate .082molAgNO3x (2molAgCl/2molAgNO3)x(143.3g/molAgCl) = 11.75g b) Assuming all the AgNO3 is exhausted, there will be 2(.044)-(.082) = .006mol CaCl2 left .006mol x (111g/mol) = 0.67g CaCl2
What are 3 ways you know a chemical change has taken place?
Three signs of a chemical reaction include the release or absorption of heat, a change in color, and the creation of a gas or a precipitate.
What is heat of reaction of Diphosphorus Pentasulfide?
If you wanted to, you could ask what the heat of formation is of a given compound such as diphosphorus pentasulfide, but if you want to know about a heat of reaction, you have to specify a reaction. A compound is not a reaction.
