C
The high conductivity of silver does not promote its use in jewelry.
<span>"Chemical weathering and physical weathering" would be the correct answer
Chemical weathering breaks down the bonds holding the rocks together, and the physical weathering will crush and break them apart.</span>
Answer:
the Law of multiple proportions
Explanation:
The law of multiple proportions states that, if two elements A and B combine to form more than one chemical compound, then the various masses of one of the elements A, which combines with a fixed mass of the element B are in simple multiple ratio.
This is demonstrated in the formation of nitrogen compounds such as NO and N2O when nitrogen combines with oxygen. This ratio is always constant.
Answer:
Explanation:
Given parameters:
Volume of CO₂ = 24cm³
time taken for the reaction to complete = 8minutes.
Unknown:
rate of reaction
Soution
The reaction rate is a measure of speed of a chemical reaction. It is often calculated using the expression below:
Reaction rate = 
Reaction rate = 
= 3cm³/min
In this reaction, 3cm³ of carbon dioxide were produced per minute
+3
Hence, the magnetic behaviour of the complex is paramagnetic. The oxidation number of the central metal atom: The oxidation number of the metal iron is +3.
