In Chemistry:
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Ores are a mixture of minerals: processed to produce an industrial mineral or chemically treated to produce one or more metals. The steel, aluminum, chromium, zinc, mercury, manganese, tungsten, and some copper ores are typically processed for just one element.
Answer:
D.) Rate-Determining Step
Explanation:
Rate - Determining Step -
The slowest step of any of the chemical reaction helps to find the overall rate of the chemical reaction , and , hence is known as the rate - determining step .
There are two type of reaction possible , one is elementary reaction and a complex reaction .
Elementary reaction is a single step reaction , and hence , that very step determined the rate of the reaction and hence is known as the rate determining step .
And ,
In case of a complex reaction , the reaction is preceded by many steps , and hence , the slowest step among other steps is known as the rate determining step of the reaction .
1,2,3, or 4. Generally, carbon likes to make 4 bonds to 4 different atoms. For example, in methane(CH4), Carbon makes 4 bonds to 4 hydrogens. However, Carbon can also make double and triple bonds to atoms. This means that of the 4 bonds, more are used to bond to one thing. For example, in the compound CN, Carbon bonds to hydrogen on one side and triple bonds to Nitrogen on the other. This shows carbon can bond to at 2 atoms as well as 4 at a time. using a one double bond carbon would only bond to 3 atoms. I cant think of an example where carbon only bonds to one other atom without breaking the octet rule, but all the other values can be validated through examples. So, I still think the bottom answer is correct. Hope this helped!
<u>Answer:</u> The equilibrium concentration of chloride ions in the solution is 4.532 M
<u>Explanation:</u>
We are given:
Initial molarity of = 0.054 M
Initial molarity of HCl = 4.60 M
Equilibrium molarity of = 0.034 M
The chemical equation for the reaction of and HCl follows:
Or,
<u>Initial:</u> 0.054 4.60
<u>At eqllm:</u> 0.054-x 4.60-2x x 6x
Evaluating the value of 'x':
So, equilibrium concentration of = (4.60 - 2x) = [4.60 - 2(0.034)] = 4.532 M
Hence, the equilibrium concentration of chloride ions in the solution is 4.532 M
