List three signs that could make you think a chemical reaction might be taking place?
Some signs that a chemical reaction is taking place is color and temperature changes, and the formation of precipitates.
List two observations from the vinegar lab that imdicates a chemical reaction took place?
Bubbles
What are examples that indicate a chemical reaction has occurred?
There are lots of telltale signs, basically any changes that happen to the reaction. For example, this could be a colour change, a mass change as a gas is given off, a pH change, a noise given off, a temperature increase/decrease, fizzing or bubbling.
Why is no chemical reaction needed to get gold?
Because Gold is an extremely unreactive metal, which means that it is not found in any compounds, e.g. Gold Oxide, but is only found on its own. So no chemical reaction is needed to obtain gold. Also, if you look at a metal reactivity series, gold will be at the bottom of the list.
What combinations could for a combustion reaction?
Any flammable or combustible material in any combination, plus oxygen. So you could have quite a long list.

If a maximum reation rate rate is 350 molecules product minute list 2 things that can increase the product rate?
In general, chemical reaction rates can be increased by the use of catalysts, and often by increasing the temperature.

Which action would cause the greatest increase in the speed of a chemical reaction?
the first answer someone provided: placing a reaction mixture in an ultrasonic shaker :) another answer: heating the mixture. another answer: adding a catalyzing agent. Please note that without specifying a LIST of possible actions in your question, it's not really possible for anyone to answer your question as stated. If you ask, "is it 'this', 'that', or 'another thing' ", then people could try to answer the question AS ASKED, by selecting one of the possible answers FROM THE LIST. When you ask 'which', there should be a list to select from, because 'which' generally means 'which of the following' or 'which of the previous'.

What are the features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
What is the chemical reaction for liver functioning?
There are an incredible number of different chemical reactions that take place in the liver, far too many to even list ("billions" is an underestimate if anything).
What is an endotherms?
An endothermic reaction is any chemical reaction that absorbs heat from its environment. Here's a list of examples of endothermic reactions. You can use these when asked to cite an example or to get ideas to set up a demonstration of an endothermic reaction or process.
What would not speed up a chemical reaction?
Cold water and large pieces.The opposite of catalytic catalysts [that enhance the rate of a specific chemical reaction] are catalytic poisons [that generally halt a particular chemical reaction].An example is the introduction of the auto-exhaust catalytic converter: the catalyst was Palladium which was being poisoned by the Lead in the gasoline so we needed to convert to unleaded gas!Another way of thinking.1-Change of pressure for Reactions having liquid or solid reactants.2-Sound3-Color4-Shape of container.5-Place.
