Answer:

Fast change

Explanation:

Weathering, erosion, and deposition are examples of slow change. Earthquakes, erupting volcanoes, and landslides happen fast. Therefore, they can change the Earth's surface very quickly.

Silver was precipitated and collected by filtration. The experiment yielded .077g of silver after dying. The predicted yield was
PSYCHO15rus [73]

Answer:

Precentage error = 7.23%

Explanation:

The precentage error formula  is the  useful method  for determining precision of your experimental result

It can be calculated using :

percent\ error = |\frac{experimental\ value-predicted\ value} {predicted\ value}|\times 100

percent\ error = |\frac{0.077\ -0.083} {0.083}|\times 100

So we get percentage error =  7.23%

Precision means how close the experimental value to the true value or theoretical value

If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment

If the percentage error is zero it means the experiment is perfectly done without  inaccuracy

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where need
gregori [183]

Answer:

Explanation:

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.

Which statement best represents the law of conservation of matter with regard to chemical reactions?(1 point)
Furkat [3]

The statement that best represents the law of conservation of matter with regard to chemical reactions would be the one that says the <u>reactants and products have the same number and type of atoms, but the atoms may be recombined.</u>

First, it is important to know that chemical reactions involve the breaking of bonds between atoms in reactants and the recombination of the atoms in products.

The law of conservation of matter also states that matter (atom) can neither be created nor destroyed in a reaction, but can be converted from one form to another.

Thus, going by the above points, the number of atoms of each element in reactants must also be the same in products. However, recombination of the atoms would most likely have occurred before reactions can take place.
