It is advisable to wear long sleeve when when a student is working in a chemistry lab so that to protect arms from lab chemicals. when someone enter the chemistry lab to wort or to study should be well prepared with appropriate gears and security measure to avoid injury.
D is the correct answer
every other option contains an element
It is going to be too low because the mass mistakenly used is lower than the initial.
Answer:
The answer is below
Explanation:
Because various factors can affect the actual value of the titration outcome. Some of these factors can range from errors from a researcher also known as human error, misreading the quantities, researcher's perception of the color, or wrong procedure in carrying out the experimentation.
Hence, in order to avoid such error, a researcher needs to be thorough during the process of experimentation, and using gross reading can help to avoid these errors when the titre value is eventually determined.
Answer:
Displaced
Explanation:
A convenient way to measure the volume of an object is to measure the volume of a solid is to immerse the solid into water.
When a solid is immersed in water, it displaces some volume of water. This volume of water displaced is the same as the volume of the object.
For instance, if the volume of water in a measuring cylinder was 25 ml and i added a stone which made the water in the measuring cylinder to rise to 70 ml, it simply means that the volume of the object is 70 ml - 25 ml = 45 ml
