What does a variable do in a math problem?
Variables in a math problem vary or change. If in an equation, different variables change values depending on constants, evanuations, etc. For example: in y = x + 2, y can be any number as long as x is that number plus two. The varibles in this equation change value but are defined by the equation.
What is a value that stays the same?
A constant is a value that stays the same and does not change throughout a problem or equation.
What is the net ionic equation for silver chloride with aqueous ammonia solution?
The net ionic equation for silver chloride (AgCl) reacting with aqueous ammonia (NH3) solution is: Ag+ (from AgCl) + 2NH3 -> Ag(NH3)2+ + Cl- where only the species that undergo a change are included. This represents the formation of a complex ion silver ammine ion.
How do you solve a equation in standard form when it has a fraction in it?
Solve it as you would normally. I could help if I had the equation. :) Fractions don't really change much; they just make the problem look more difficult.
What is an example problem of a polytropic process?
An example problem of a polytropic process is when a gas undergoes compression or expansion while its pressure and volume change, following a specific mathematical relationship known as a polytropic equation.
What is then net ionic equation of silver nitrate and sodium chloride?
The net ionic equation for silver nitrate and sodium chloride is: Ag⁺(aq) + Cl⁻(aq) → AgCl(s) This equation shows the formation of a white precipitate of silver chloride when silver nitrate and sodium chloride are mixed together in aqueous solution.
Does silver react with HCL?
Yes, silver does react with hydrochloric acid (HCl) to form silver chloride (AgCl) and hydrogen gas (H2). This reaction is a chemical change where the silver is dissolved by the acid to form a new compound.
Is tarshing silver a chemical change?
No, tarnishing silver is a physical change. It occurs when silver reacts with sulfur compounds in the air to form silver sulfide on the surface of the silver. This reaction does not change the chemical composition of the silver, only its appearance.
NEED help writing a chemistry equation Please help A copper coin was kept in the solution of silver nitrate after sometime when it was taken off?
You need to give more information. What color was the coin after the reaction, and did the silver nitrate solution change color?
How can you change one format of an equation into another?
by changing the equation into another
What is a unknown or change quantity?
An unknown or changing quantity is a variable in a mathematical equation or problem that is not fixed but can take different values. It is typically represented by a letter, such as x or y, and its value needs to be determined in order to solve the problem.
Is silver tarnishing chemical change or chemical property?
Tarnishing of silver is a chemical change. It occurs when silver reacts with sulfur-containing substances in the air to form silver sulfide, which is the black tarnish seen on the surface of the metal. This change is irreversible and alters the composition of the silver.
