What else can I help you with?
Select all the conditions below that are most likely to result in a spontaneous chemical reaction or process?
Exothermic reaction Decrease in entropy Increase in entropy Positive change in free energy Negative change in free energy
Can a measurement standard be easily changed to suit the experiment?
Changing a measurement standard to suit an experiment depends on various factors including the nature of the experiment and the level of precision required. In some cases, it may be possible to calibrate or adjust the standard, but this can introduce errors and uncertainties. Generally, it is preferred to select an appropriate measurement standard that aligns with the experiment's requirements to ensure accurate and reliable results.
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'.
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?
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
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
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 all the conditions below that are most likely to result in a spontaneous chemical reaction or process?
Exothermic reaction Decrease in entropy Increase in entropy Positive change in free energy Negative change in free energy
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.
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.
How can I choose a buffer solution based on pH for my experiment?
To choose a buffer solution based on pH for your experiment, first determine the desired pH range for your experiment. Then, select a buffer solution with a pKa value closest to the desired pH. This will help maintain the pH of your solution within the desired range and prevent drastic changes in pH during the experiment.
How do you select the right chemical to use on client thio or hydroxide?
To select the right chemical for a client, consider their hair type, texture, and previous chemical treatments. Thio is milder and better suited for delicate or damaged hair, while hydroxide is stronger and more suitable for coarse, resistant hair. A thorough consultation and strand test can help determine the best chemical for your client's specific needs.
What are the compounds needed in order for an experiment to be valid?
The necessary compounds depend on the specific experiment being conducted. However, common compounds include reagents for reactions, solvents for dissolving substances, standards for calibration, and control substances for comparison. It is essential to carefully select and prepare these compounds to ensure accurate and reproducible results in the experiment.
How do you improve the validity of the experiment?
To improve the validity of an experiment, ensure that the experiment is well-designed with controlled variables to isolate the effect of the independent variable on the dependent variable. Use random sampling to select participants and random assignment to groups to minimize bias. Additionally, replicate the experiment to confirm results and gather more data for robust conclusions. Finally, ensure that measurement tools and methods are reliable and valid for assessing the outcomes.
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.
How scientist decide which microscope to use in work?
Scientists typically choose a microscope based on the specific needs of their experiment or research. Factors they consider include the type of sample being studied, the level of magnification and resolution required, the imaging techniques needed (such as fluorescence or phase contrast), and the budget available for equipment. Ultimately, the goal is to select a microscope that will provide the best quality images and data for their particular scientific investigation.
