Select all the conditions below that are most likely to result in a spontaneous chemical reaction or process?
-ΔH +ΔS T high -ΔH -ΔS T low
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
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 kind of water must be used for chemical analysis?
Tap water has been treated with chemicals to make it safe for drinking, not to mention that local minerals and debris from the pipes could make for a bad test sample. Pure water is a 7 on the scale, a true neutral.
If you have performed a transformation experiment using a mutant strain that is arg-- trp plus gal-- his--.?
You have performed a transformation experiment using a mutant strain that is arg-- trp+ gal-- his--. A culture of this mutant strain was mixed with a DNA from another mutant strain that is arg+ trp-- gal+ his+. How will you select for the following recombinants? a) arg+ trp+ gal-- his-- b) arg+ trp-- gal+ his+ c) arg-- tryp-- gal+ his-- d) arg-- trp+ gal-- his+
Select the organism that would not be studied by a botanist?
A mushroom
Select all the conditions below that are most likely to result in a spontaneous chemical reaction or process?
-ΔH +ΔS T high -ΔH -ΔS T low
How do i find the sum of outcomes in probability?
Select an experiment that has a random result rather than one that is deterministic. The result of the experiment is the outcome of the probabilistic experiment.
Select the skeleton equation?
A skeleton equation in chemistry contains obviously the abbreviations of the elements you are being asked to represent. it may contain the exponents also known as subscripts but it does not include coefficients.
Select all of the conditions below that are most likely to result in a nonspontaneous chemical reaction or process The Gibbs free energy equation is ΔG equals ΔH TΔS?
+ΔH,-ΔS, T low -ΔH,-ΔS, T high
When Select three different bottles of juice drink. Select thirty respondents among your friends and ask them to evaluate the drinks then ask them why they like it. Record the answer. Rank the attribu?
This is obviously part of a set of instructions for a science experiment. Follow the instructions and actually do the experiment and you will probably get a pretty good grade.
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
Select the statement that makes the following statement TRUE - When a new chemical is introduced to the work area or if chemical handling requirements change you must contact the sites Environmental?
Process generating the waste.
What are some side effects of products that are tested on animals?
go to http://www.all-creatures.org/ and select pictures........click on an animal and scroll down until you see experiment.
If you were asked to create a salt compound what reactants would you select and what products would the reaction yield?
Because of the conservation of matter no mass can be destroyed or created.

What experiment would you do to show how the amount of distance affects velocity over a period of time?
I am not sure how you would do that. However, it is relatively simple to set up an experiment to show that velocity (over a period of time) affects distance. Select an object whose velocity can be changed from one constant value to another. Alternatively, select a set of objects that can travel at different, but constant, velocities. Measure the distance travelled by each object in the chosen time period (or have a race).
