A scientist should form a hypothesis, then conduct an experiment describes the correct order for using the scientific method. Thus option A is correct.
Scientific method can be defined as to answer the question, a continuous experiment, investigation which are applied in a scientific method, includes measurable observation, develop experiment and improve a hypothesis and formulate phenomenon.
The different steps of Scientific method are involve in Making an Observation is involved the different steps like inspection, conducting the investigation by asking questions.
Asking Questions most important step and it is used to make sure that every details are known and the query can be solved quickly.
To construct the Hypothesis, it involves proper explanation of the query and it is most significant part of the scientific method.

Answer:
A
Explanation:
C. Vinyl or neoprene gloves provide protection against hazardous chemicals due to their resistance to chemical exposure. Latex gloves can be permeable, and padded cloth gloves are not designed for chemical protection.
C. Vinyl or neoprene gloves are the appropriate choice for protecting hands from hazardous chemicals. Here's why:
1. Chemical Resistance: Vinyl and neoprene gloves offer excellent resistance to a wide range of chemicals, including acids, bases, solvents, and oils. This resistance creates a barrier that prevents hazardous chemicals from coming into contact with your skin.
2. Latex Allergies: Latex gloves (option A) can cause allergic reactions in some individuals, which can be severe. It's important to avoid latex gloves when working with hazardous chemicals to prevent potential allergic responses.
3. Physical Protection: Padded cloth gloves (option B) are typically designed for physical protection and comfort, not for chemical resistance. They may not provide an effective barrier against chemical exposure, making them unsuitable for this purpose.
4. Versatility: Vinyl and neoprene gloves are versatile and can be used in various laboratory, industrial, and healthcare settings where protection against chemical hazards is necessary.
5. Durability: These gloves are known for their durability and resistance to wear and tear, ensuring that they maintain their protective properties even during prolonged use.
It's essential to choose the right type of gloves based on the specific chemicals you are handling and their compatibility with the glove material. Always consult safety guidelines and material compatibility charts to select the most appropriate gloves for your specific chemical-handling tasks, ensuring the safety of your hands and skin.

the correct answer would be A. Latex Gloves. vinyl or neoprene gloves will be eaten by most highly toxic chemicals and some lower toxicity chemicals and padded cloth gloves will just soak up the chemical.
hope this helps:)
The two categorical ways of thinking about the matter are discussed in the passage are physical and chemical.
The matter has been the unit, from which everything is made up of. The passage asks about the matter has been the part of each and every physical and chemical reaction.
All the matter has an atom as its smallest building block. The elements listed in the periodic table also matter. The smallest and the biggest entity has consisted of matter.
The physical categorial way of thinking of matter involves the properties that can be sensed by the five human senses. The things that can be seen, heard, tasted, touched, and felt are all matters.
The chemical properties of the matter that result in the formation of a new matter that is irreversible in nature.

Answer:
There's no passage but I can say that matter are that ''thing'' which extend through all Universe, matter is everything. It can be seen or felt as liquid, gas or solid. This changes of its state depend on the amount of energy that is involved.
So, here is used categorical thinking because is a abstract concept that is hard to understand sometimes. It's abstract when we say that matter is all, not just what we see, but even what we don't see like ''Dark Matter'', which is the majority in the Universe.
Chemically combined​
Answer:
A compound
Explanation:
A compound is a substance made up of two or more components that are chemically combined together.
The substances that combines to form a compound is called elements.
The properties of compounds are distinct and different from the elements that combines to make them.
A wide array of compounds are known and they arise from different arrangements of atoms of elements.
