Answer:
5 mL
Explanation:
When an object is completely submerged in a liquid , it displaces liquid equal to its volume . Therefore level of liquid is raised in a container containing liquid .
When the irregularly shaped object is totally submerged the volume of water in a graduated cylinder increases from 10 mL to 15 mL.
Initially volume of water contained = 10 mL
volume of water + volume of irregular shaped object = 15 mL
volume of irregular shaped object = 15 - 10 = 5 mL .
Answer:
40 grams.
Explanation:
If 20 grams of C is formed from the combination or reaction of A and B chemicals in 10 minutes, 40 grams of C is formed in 20 minutes because the time is doubled so the concentration of C chemical is also doubled. If the time is increased further, more concentration of C chemical is produced until the amount of chemicals A and B are present. If we put an enzyme in the solution, the time of the reaction can be reduced.
Answer:
A
Explanation:
The carrot itself was made up of the same chemical bonds and chemicals even when it was cut but it was cut affecting the form/shape
In chemical changes, the object undergoes a change where the chemicals themselves undergo a change
KOH -------------> K⁺ + OH⁻
pOH = - log [ OH⁻ ]
pOH = - log [ 1 x 10⁻⁵ ]
pOH = 5
pH + pOH = 14
pH + 5 = 14
pH = 14 - 5
pH = 9
hope this helps!
