What else can I help you with?
A compound is added to a solution of hydrochloric acid and the solution is observed to see if a reaction takes place Chemical is being tested?
The reaction may indicate the presence of a metal compound that can react with hydrochloric acid to form a metal chloride and hydrogen gas. The observation of bubbling or fizzing would suggest a chemical reaction has occurred. Additional tests may be needed to identify the specific metal present in the compound.
How can you tell for sure that a redox reaction has happened?
if oxidation states change, it is a redox reaction
Is vinegar reacting with baking soda a physical change?
No, the reaction between vinegar and baking soda is a chemical change because new substances are formed (carbon dioxide gas, water, and sodium acetate) with different properties than the original substances. This is a chemical reaction, not a physical change.
How you tell if matter has undergone a chemical change or a physical change?
If a chemical change has occurred, the chemical composition has changed and new products will have formed, different from the reactants. If a physical change has occurred, the chemical composition does not change and no new products will have formed.
A change in color is evidence of a change?
yes **Why? I need more than just yes. Tell why.** ok ok ok its not always a sign that there is a reaction but in most cases it will be. things that show a reaction are temperature change (usually increase but not always) mass change, state change or physical change. hope this helps
What observations suggest that a chemical reaction has occurred?
One observation that a chemical change has occurred is the formation of a new product. Another observation is the change in identity and composition of a substance.
If new products are made in a chemical reaction what does that suggest about the reaction?
No new products can be made in a chemical reaction. Only the reactants exchange or react with another element.
What are clues that a chemical reaction has taken place A Formation of a gas B Constant temperature C Steam D Change in color?
A) Formation of a gas: Bubbles or fizzing can indicate the release of a gas during a chemical reaction. C) Steam: The presence of steam may indicate that water is being formed as a product of the reaction. D) Change in color: A noticeable change in color of the substances involved can suggest a chemical reaction has occurred.
Suggest 2 observations when Ca reacts with water?
The reaction is:Ca + 2 H2O = Ca(OH)2 + H2- hydrogen gas is released- the reaction occur at room temperature

Experimental observations suggest a gas is being released?
steam
Can you use a permanent marker as makeup?
Wouldn't suggest it. Permanent marker often contains chemical that aren't safe for the skin and may cause a reaction.
Suggest a chemical test(s) to distinguish ethanol and phenol. Include the reagents reaction conditions and observations. And the equation?
Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.
