Answer:
When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue.
Explanation:
After reading your question, we can see that you are carrying out a test to discover the nature of the pH of a solution. This type of test uses litmus paper, which is an indicator of the presence of acids and bases, being able to determine the pH of a solution. This paper is soaked in organic ink and when placed in an acidic solution, it is red in color. However, when placed in a basic solution it has a blue color.
An acidic solution is one that has a high concentration of H+ atoms and has the ability to donate electrons. The basic solution, on the other hand, has a high concentration of OH- and has the capacity to receive electrons.
When you move the burette slider to the top of a flask and add about 25 mL of NaOH to the flask, you will cause a concentration of OH- molecules. This will make the solution become a basic solution and make the litmus paper blue, that is, the solution has the basic pH.
Answer:
what kind of class u in like dam
Explanation:
Answer:most of the positively charge particles should be bounce back at a range of angles as they collide with the atoms in the foil; only a few should pass straight through the foil
Explanation:
Answer:
SPECIFIC HEAT CAPACITY
Explanation:
Q = MC DELTA T
q = heat
c = specific heat
T = temperature ( final - initial )
Hello!
The fission of an atom that has a large atomic number can be induced by bombarding the atom with neutrons.
Nuclear fission occurs when a heavy nucleus divides into two or more lighter nuclei. This reaction is induced by the bombarding of neutrons into the nucleus, making it unstable (like throwing an orange to a perfectly arranged orange pyramid at the supermarket). The unstable nucleus breaks down into lighter elements, releasing more neutrons which contribute to the chain reaction.
Have a nice day!
