Explanation:
Working in laboratory is very dangerous when working with chemicals. It can burn the skin if it falls or if someone comes in contact with it. We should always be alert and be careful while handling chemicals in the laboratory. Safety measure should always be followed like wearing gloves and aprons. While mixing chemicals, always hold the flasks straight right in front of you with the help of a crucible tong or a test tube holder and move straight.
Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.
<h3>What is a separation technique?</h3>
A separation technique can be defined as a technique that is used to separate (convert) two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
In Chemistry, sodium hydroxide, caustic soda, or lye all refer to the same chemical compound which is represented by this chemical symbol, NaOH.
According to the narration, Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

He stated that most of the mass of the atom is concentrated in the center of the atom which was against the plum pudding model, so he disproved to that
Q: Which type of severe weather is related to high-pressure systems
A: A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies. A high pressure system is represented as a big, blue H.
If you take this answer into consideration knowing the weathers, you will get your answer
Answer:
False.
Explanation:
1. Most liquids do not have ionized atoms or particles within them, as the state of matter does not really allow that to freely happen.
2. Liquids may not have a definite shape, however, they have a definite volume. No matter the container you pour them into, their volume remains constant.
3. Liquids are not good conductors of electricity. Take for example water. Pure water does not conduct electricity
Hence, the statement is false with regards to liquids. However, it is true when talking about the foruth state of matter - Plasma
