B. the state of matter change
C.there is a decrease in mass.
D. the matter is stirred thoroughly
Answer:
option A. There is a color change
If we have any substance, can be concluded that a chemical than there is a color change. Thus, option A is correct.
What is molecule?
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions.
The simplest forces between atoms are those which arise as a result of electron transfer. A simple example is that of say sodium fluoride. The sodium atom has a nuclear charge of +11, with 2 electrons in the K shell, 8 in the L shell and 1 in the M shell. The fluorine atom has a nuclear charge of 9 with 2 electrons in the K shell and 7 in the L shell. Two or more atoms held together with bonds make up a molecule.
Therefore, If we have any substance, can be concluded that a chemical than there is a color change. Thus, option A is correct.

C.Two liquids are mixed, in a solid substance formed
D. A piece of paper is cut into many small pieces
Answer:
A
Explanation:
be it’s a Chemical change not a physical change
Two liquids when combined to form a solid substance is an example of chemical change as rearrangement of atoms takes place in the process.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

The periodic table organizes all the known elements in a way that gives the reader many clues as to the element's properties and make-up. What can you infer about copper (Cu, atomic number 29) and silver (Ag, atomic number 47) based on their positions relative to EACH OTHER on the periodic table?
Please hurry!
Answer:
The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.

Explain how errors in measurements can affect the safety of products. (It an essay)
Answer:
An error or fault can be described as the disparity between the calculated worth and the exact worth. For instance, if the two machinists use a similar instrument for discovering the errors in measurement, it is not required that they may acquire the related outcomes. But, there will be a slight variation between both the measurements which is known as an error. In sequence, to know the idea of errors in measurement, one has to recognize the two conditions that describe the error namely measured value as well as true value. The “true value” is unfeasible to find out the accuracy of measurement by experimental means that can be defined as the standard value of a countless number of calculated values. This value can be described as the expected value of true value which can be established by taking numerous calculated values throughout experimentation.

Bart believes that mice exposed to radio waves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice near a radio for 5 hours. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. he found that 8 out of 10 of the radio-waved mice were able to push the block away. 7 out of 10 of the other mice were able to do the same.

Explanation:The saturated zone beneath the water
An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.
