Answer:
Here is ur answer;
- Modern research in chemistry has impacted society by allowing us to make informed decision. With the knowledge of chemistry, you can form better opinions about today's news. You will be able to distinguish the truth from the lies in environmental reporting and better understand the meaning of a chemical spill.
- Modern research in chemistry can lad to technologiesthat aim to benefit the environment, conserve and produce energy, improve human life, and expand our knowledge of the universe. Modern research in chemistry has impacted society by gathering data from afar analyse matter that is brought back to the earth.
- The industrial application of chemistry directly affects our daily lives --- what to eat, what we wear, our transport, the technology we use, how we treat our illness and how get electricity -- to name a few. Research is constantly deepening our understanding of chemistry and leading to new discoveries.
- Chemistry is essential to meeting our basic needs of food, clothing, shelter, health, energy and clean air, water and soil. Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems of health, problems in health, materials and energy usage... For better or for worse, everything is chemical.

It’s a nonet because an octet is 8, a quartet is 4, and a duet is 2.
Answer:
(A) 4×0.0001M
Explanation:
[OH-] = 10^-3.4 which is equivalent to 4×0.0001M
Properties of matter can be broadly classified into two categories:
-Physical properties, these usually involve a change in the state of matter
-Chemical properties. these involve a change in the chemical composition of matter.
Now, physical properties can be further classified as:
Extensive: these depend on the amount of the substance, eg: mass, volume
Intensive: these do not depend on the amount of the substance eg: density, color, melting point, boiling point
A physical property that does not describe a change in state is color. For example: copper sulfate is a compound which is a blue in color. Thus, color provides information which describes the appearance of matter. In contrast, properties like melting or boiling point suggests a change in the state of the substance.
Answer:
Electrons get farther from the nucleus.
Explanation:
By going from the top to the bottom of a group, the atomic number increases. That would mean that:
- The number of orbitals increases, as there are more electrons.
- A higher atomic number implies an increasing number of neutrons.
- As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
