Answer:
n California there are two plates - the Pacific Plate and the North American Plate. The Pacific Plate consists of most of the Pacific Ocean floor and the California Coast line. The North American Plate comprises most the North American Continent and parts of the Atlantic Ocean floor. The primary boundary between these two plates is the San Andreas Fault. The San Andreas Fault is more than 650 miles long and extends to depths of at least 10 miles. Many other smaller faults like the Hayward (Northern California) and the San Jacinto (Southern California) branch from and join the San Andreas Fault Zone.
The Pacific Plate grinds northwestward past the North American Plate at a rate of about two inches per year. Parts of the San Andreas Fault system adapt to this movement by constant "creep" resulting in many tiny shocks and a few moderate earth tremors. In other areas where creep is NOT constant, strain can build up for hundreds of years, producing great earthquakes when it finally releases.

A chemical equation can be used to solve stoichiometry problems provided that it....
indicates only the forward reaction and not the reverse.
indicates that reactants are in the gas phase and are not solids or liquids.
includes the coefficients that are needed for balancing the equation.
includes the state of matter after each substance.
Answer:
includes the coefficients that are needed for balancing the equation.
Explanation:
A chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.Hence, Option (C) is Correct.
What is Balanced Equation ?
An equation that has an equal number of atoms of each element on both sides of the equation is called a balanced chemical equation, i.e., the mass of the reactants is equal to the mass of the products.
Therefore, A chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.Hence, Option (C) is Correct.

When an object that is made of magnetic material but is not a magnet comes in contact with a magnet _____. PLS ANSWER FAST
Answer:
Magnetic domains fall into alignment and it begins to attract other objects.
Fields allow some objects to exert forces on each other even when they are not ________.
Answer:
in contact
Explanation:
Fields allow some objects to exert force on each other even when they are not contact with one another.
The region of space where the effect of a force is felt is know as a field.
Field forces for provides a non-contact means of exerting forces. They objects do not have to be in contact before the force is felt. An example is the gravitational force field.Fields allow some objects to exert forces on each other even when they are not in contact .

in the molecule?
O 1:1
1:3
O 1:6
3:1
3:6
61
361
Answer: The ratio of carbon to bromine atoms in the molecule is 3:1
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions.
Chemical formula shows the elements in a compound and the relative proportions of those elements.
The chemical formula given for the compound is [tex]C_3H_6BrCl[/tex] which means the ratio of carbon to bromine atoms is 3: 1.
Thus the ratio of carbon to bromine atoms in the molecule is 3:1

Why is it difficult to detect the presence of isotopes of an element during chemical
studies?
Answer:
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.
What is the volume of 8.80 g of CH4 gas at STP?
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.

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.

Does this equation follow the laws of conservation of mass? why?
CuO(s) + H2(g) = Cu(s) + H2O(g)
(twos are subscript_)
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.
What would happen to a plant if you grew it in a room without cabon dioxide
Answer:
One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night. In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die.17/01/2019
