What is the evidence that a chemical reaction occured in silver nitrate and potassium iodide?
The evidence that a chemical reaction occurred in the reaction between silver nitrate and potassium iodide is the formation of a yellow precipitate of silver iodide. This precipitate forms due to the exchange of ions between the two reactants, resulting in the creation of a new compound with different chemical properties than the original substances.
How you can get water element?
The chemical compound Water is made of two elements: Hydrogen and Oxygen. To get water you would need to perform a highly explosive chemical reaction. An example of this dangerous reaction occured with old style zeppelins that were filled with Hydrogen. So, the chemical formula of water is H2O and the reaction between Hydrogen and Oxygen is:Hydrogen + Oxygen --> Hydrogen OxideDo not attempt this reaction.
Gold is added to a solution of calcium chloride?
When gold is added to a solution of calcium chloride, no reaction occurs as gold is a noble metal and is unreactive in most chemical reactions, including with calcium chloride. The gold will remain as a solid in the solution without forming any new compounds with the calcium chloride.
What evidence from rock layers could show a scientist that earthquakes have occured?
firstly let me say that putting your homework on wiki is sooo not cool! Back in my day there was no internet to look up our answers... Well, signs in the lithosphere could show on the ground. For example, a normal fault, a reverse fault, or a strike-slip fault could show. Your Welcome! But, Please next time you should do your homework.
What is the highest average monthly rainfall for khartoum?
The highest one is 16 and it occured on December.
When substances are different from the starting substances what occured?
This is a chemical reaction.
What can be evidence of a chemical reaction?
Evidence of a chemical reaction can include formation of a gas, color change, temperature change, formation of a precipitate, or production of light. These observable changes indicate a transformation of substances into new molecules with different properties.
What happens in a can of spoiled food as gas is produced?
A chemical reaction of food decomposition occured.
Why does a change in teperature indicate that a change reaction may have occured?
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
What type of reaction has occured when two or more substances combine to form another substance?
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
Why doesn't the production of gas doesn't always indicate that a chemical reaction has occured?
Immersing a heated noble metal in water will create water vapour without anything undergoing a chemical reaction. Phase change in some of the water, though.
How can someone tell when equillibrium in a reaction has occured?
Equillibrium in a reaction has occured when the concentration of compounds remain unchanged.
How does the chemical equation show that a chemical reaction has occured?
A chemical equation shows that a chemical reaction has occurred by representing the reactants transforming into products through chemical bonds breaking and forming. The equation includes the chemical formulas of the reactants before the reaction arrow and the products after, indicating a rearrangement of atoms and a change in chemical structure. Balancing the equation ensures that mass is conserved, further confirming a chemical change has taken place.
Jorge added a solid material to a clear colorless liquidthe mixture began to bubblee xplain why jorge thought a chemical reaction occurreed?
if a person added a solid material to a colorless liquid and the mixture started to bubble if the person wrote in his notebook a chemical reaction occured explain why that person thought it was a chemical reaction?
When two or more substances combine in a chemical reaction to form another substance the reaction that has taken place is?
If 2 or more reactants produce a single product, then a synthesis reaction has occured.
What are the five clues that suggests a chemical reaction is taking place?
first when there's a physical change in the substance second there will be a solution or a formula to that substance third is, it involves temperature fourth is change in color of the substance fifth is the bubbling of another substance is yet an another clue that a chemical reaction has occured.
When two white compounds are mixed in a solution a yellow solid forms What kind of reation has taken place?
A chemical reaction that has taken place is likely a precipitation reaction. The formation of a yellow solid suggests the creation of a new compound that is insoluble in the solution and precipitates out.
