Temperature is an important factor that determines if matter is a solid or a liquid
True or false?
Answer:
true
as temperatures rise, the atoms become more active; as per the opposite (meaning as temperatures drop, the atoms start to settle down) liquid is the more medium state (because the temperature rises enough for the solid to become a a liquid but not too much that the liquid evaporates and turns into a gas) have a great day/night

Hammerhead Shark Process of Sexual Reproduction
Answer:
The hammerhead sharks exhibit a viviparous mode of reproduction with females giving birth to live young. Like other sharks, fertilization is internal, with the male transferring sperm to the female through one of two intromittent organs called claspers. The developing embryos are at first sustained by a yolk sac.

Different species of animals in a community would most likely be similar in O A. physical structure. O B. size. O c. abiotic requirements. O d. number of offspring produced. O E. genetic make-up.
Different species of animals in a community would most likely be similar in physical structure, basic nature of an ecosystem. thus option A is correct.
what is ecosystem ?An ecosystem can be defined as a community of living organisms concurrence with non-living components, interacting with each other in an environment.
The structure of an ecosystem composed of both biotic and abiotic components which include the distribution of energy in our environment, climatic conditions prevailing in that specific environment.
The structure of an ecosystem can be divided into two components such as Biotic Components and Abiotic Components
both biotic and abiotic components are interrelated with each other in an ecosystem,. it is an open system where the flow of energy and components occur throughout the boundaries.
The functions of the ecosystem include regulates the essential ecological processes, responsible for the cycling of nutrients between biotic and abiotic components, maintains a balance among the various trophic levels in the ecosystem.

Balance the follwing equation:
BLANK C+ BLANK H(2) -> BLANK CH(4)
Everything in partnethesis are subscripts.
Thanks!
Answer:
- in order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.
equation: (given)
__ C + __ H2 --> __ CH4
C = 1 | C = 1
H = 2 | H = 4
so, here we can see that the number of hydrogen (H) atoms are NOT equal, which means we have to put a number infront of the compounds inorder to balance it. this means putting a coefficient.
equation: (balanced)
C + 2H2 + CH4
- the only thing added was the 2.

1. define what an ion is (make sure electrons are part of the definition)
2. explain (in terms of electrons) how the sodium is becoming a positive ion
3. explain (in terms of electrons) how the chlorine is becoming an a negative ion
4. Explain why the difference in charges causes them to become attracted and bond to make NaCl, also known as table salt.
Answer:
valence shell, has eight electrons in it, so the atom becomes positively charged. ... in energies and is useful in explaining why atoms form the ions that they do. ... which we write as Na 2O. The need for the number of electrons lost
Explanation:
1. An ion of an atom is one in which the number of protons and electrons is not the same. If there are more protons than electrons, an atomic ion has a positive charge and is called a cation. If there are more electrons than protons, the ion has a negative charge and is called an anion.
2. Such bonds are created when the outermost electrons of one atom (such as sodium) are transferred permanently to another atom (such as chlorine). The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
3. For a chlorine atom to become a chloride ion, it must gain an electron. The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full octet, it gains an electron. A chloride ion is called an anion. Its electron configuration is 1s2 2s2 2p6 3s2 3p6.
4.Ionic bonds are also formed when there is a large electronegativity difference between two atoms. This difference causes an unequal sharing of electrons such that one atom completely loses one or more electrons and the other atom gains one or more electrons, such as in the creation of an ionic bond between a metal atom (sodium) and a nonmetal
