Describe the freedom of movement of particles as a substance changes states of matter from solid to liquid to gas.
Answers
Answer:
in a sold the particles are in a fixed position and can only vibrate on the spot but when it changes into a liquid the energy is used to weaken the bonds so there are weak forces of attraction between the particles, all particles are still touching each other but are now free to move around. Ina gas all the bonds are broken, the gas particles are free to move around anywhere and the more collisions there are, the more the pressure increases

Answer:
The Latin word for the Sun is Sol, so we call this system the Solar System. He showed that it was very likely that all the planets moved around the Sun. This time even more people thought Galileo may be right and that the Earth really did move around the Sun.
Explanation:
There are many planetary systems like ours in the universe, with planets orbiting a host star. Our planetary system is named the "solar" system because our Sun is named Sol, after the Latin word for Sun, "solis," and anything related to the Sun we call solar.

When you sweat a lot the water content of your blood can drop. Your cells have to maintain a certain level of water and salt in order to function properly. Which systems work together to help maintain homeostasis.
Answers
Answer:
Explanation:
There are key organs and system that assist in ensuring the body maintains homeostasis in the case of water-salt balance.
The excretory system: When one sweats, a lot of water content of the blood can drop (this is what causes the individual to be thirsty). In order to maintain a certain water-salt balance, the excretory system passes some salt out of the body in the form of urine (this is the reason the urine is usually yellowish but small in volume during the summer).
Endocrine system: When water content of the blood drops, vasopressin (also called antidiuretic hormone) is released into the bloodstream stimulating the kidneys to conserve water and release less urine (as said earlier). However, if the body is hydrated, less vasopressin is released and more water is passed in the urine.
10. Write the formula for the compounds: copper (1) chloride and copper (II) chloride
Answers
Answer:
Copper(II) chloride (CuCl2) reacts with several metals to produce copper metal or copper(I) chloride (CuCl) with oxidation of the other metal.
Explanation:
There are two types of chemical compound one is covalent compound and other is ionic compound. The formula for the compounds: copper(I) chloride and copper (II) chloride are CuCl and CuCl[tex]_2[/tex] respectively.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.
The chemical formula for Copper(II) chloride is (CuCl[tex]_2[/tex]). The chemical formula for copper(I) chloride (CuCl). The number in the roman is the oxidation state of the metal. Copper(II) is called cupric, copper(I) is called cuprous.
Therefore, the formula for the compounds: copper(I) chloride and copper (II) chloride are CuCl and CuCl[tex]_2[/tex] respectively.

What is the volume of 8.80 g of CH4 gas at STP?
Answers
Answer:
12.32 L.
Explanation:
The following data were obtained from the question:
Mass of CH4 = 8.80 g
Volume of CH4 =?
Next, we shall determine the number of mole in 8.80 g of CH4. This can be obtained as follow:
Mass of CH4 = 8.80 g
Molar mass of CH4 = 12 + (1×4) = 12 + 4 = 16 g/mol
Mole of CH4 =?
Mole = mass/Molar mass
Mole of CH4 = 8.80 / 16
Mole of CH4 = 0.55 mole.
Finally, we shall determine the volume of the gas at stp as illustrated below:
1 mole of a gas occupies 22.4 L at stp.
Therefore, 0.55 mole of CH4 will occupy = 0.55 × 22.4 = 12.32 L.
Thus, 8.80 g of CH4 occupies 12.32 L at STP.

What is an element?
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Does this equation follow the laws of conservation of mass? why?
CuO(s) + H2(g) = Cu(s) + H2O(g)
(twos are subscript_)
Answers
Answer:
Yes
Explanation:
Chemical equation:
CuO + H₂ → Cu + H₂O
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given reaction:
CuO + H₂ → Cu + H₂O
there are 1 copper atoms, one oxygen atoms and two hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
