Answer:
Intensive and extensive properties are both physical properties. However, intensive properties dont depend on the amount of matter present in a sample, whereas extensive properties do. Intensive properties only depend on the type of matter, such as color, temperature, or solubility. Extensive properties depend on the amount of matter, such as mass, volume or energy

Can someone help me balance these chemical equations?
1. CuF2 + Mg ---------> MgF2 + Cu3
2. Na + H2O ----------> NaOH + H2
3. KBr + Cl2 ------------> KCl + Br2
Explanation:
(1) CuF2+Mg-------->MgF2+Cu
(2) 2Na+2H2O --------> 2NaOH+H2
(3) 2KBr+Cl2-------->2KCl+Br2
Which shared derived characteristic do reptiles, marsupials, and dogs have?
Amniotic egg
Fur
Retractable claws
Shearing teeth
Answer:
Shearing teeth
Explanation:
Just use process of elimination. Dogs don't lay eggs, reptiles don't have fur, neither of them have retractable claws, so the only one left is shearing teeth.

(7th grade chemistry) What makes a polyester, nylon and acrylic a synthetic materials/ products, in other words what happen during polyester, nylon and acrylic chemical reaction?(or what happen during a chemical reaction)
Explanation:
What you call polyester is technically polyethylene terephthalate or PET plastic molded into filaments that are then woven into fabric. It's made in a chemical reaction between ethylene glycol and therephthalic acid, and these chemicals are derived from fossil fuels, air, and water.
Nylons are condensation polymers or copolymers, formed by reacting difunctional monomers containing equal parts of amine and carboxylic acid, so that amides are formed at both ends of each monomer in a process analogous to polypeptide biopolymers. Most nylons are made from the reaction of a dicarboxylic acid with a diamine or a lactam or amino acid with itself
The binder resin in acrylic paint is man-made, most of the time in some sort of lab. It is made generally from the monomer methyl methacrylate and also any real common catalyst. The catalyst speeds up the reaction to where the monomers create extremely long chains. Which result in polymethyl methacrylate, an acrylic plastic polymer.
The pigments are also mostly made in labs/factories. Most of the time they are either pure elements like pure cobalt powder and carbon charcoal, or they basic bounded compounds like cadmium sulfide. To make cadmium sulfide you react cadmium chloride with hydrogen sulfide to make a bright yellow solid. It is then washed and heated to make a spectrum of different colors.
Basically all of acrylic paints are man-made through various chemical reactions.
How is precambrian time different from other divisions of the geologic time scale?
Precambrian time is different from other divisions of the geologic time scale as the life forms in this time had soft bodies.
What are geologic time?Geologic time is the time that is begins at the start of the Archean eon and it is the extensive interval of time occupied by the geologic history of the earth.
Precambrian time is the the earliest time of the geologic ages, which are marked by different layers of sedimentary rock including the fossilized remains of plants and animals buried when the sediments were formed. Main difference between both the times is in Precambrian time life-forms had soft body parts and in Geologic time life-forms had hard body parts.
Hence main difference is of life forms.

Which of the following organisms evolved after amphibians?
Only cats
Only reptiles
Only marsupials and cats
Reptiles, marsupials, dogs, and cats
Answer:
Reptiles, marsupials, dogs, and cats
Explanation:
The correct answer is only reptiles as they evolved after amphibians.
Amphibians were one of the earliest groups of land-dwelling vertebrates to evolve. After amphibians, reptiles emerged. Reptiles are a diverse group of cold-blooded vertebrates that includes animals such as lizards, snakes, turtles, and crocodiles. They have adapted to a wide range of environments, including deserts, forests, and oceans.
The other options provided in the question, such as cats, marsupials, and dogs, did not evolve after amphibians. Cats and dogs belong to the mammal group, which evolved much later than amphibians. Marsupials, on the other hand, are a group of mammals that includes animals like kangaroos and koalas. While marsupials did evolve after amphibians, the question specifically asks for organisms that evolved "after amphibians," excluding any other groups that may have evolved concurrently.
So, the correct answer is "Only reptiles" because reptiles evolved after amphibians.

Answer:
Travis categorized their characteristics correctly.
Explanation: This is because plants use chloroplast in their cells to help them with photosynthesis, and this is what turns them green. Animals do not make their own food so they have no use for chloroplast in their cells.
