The sun is in the middle baby :)
Answer:
True
Explanation:
ion: an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Answer:
Explanation:
Solution,
For Johnathan
Distance(d)=800m
Time(t)=200sec
Now,
Speed=d/t=800/200=4m/s
For Abby
Distance(d)=200m
Time(t)=40sec
Now,
Speed=d/t=200/40=5m/s
Here, Abby is faster by 1m/s.
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.
