The balanced reaction that describes the reaction between sulfur<span> and oxygen to </span>produce sulfur dioxide<span> is expressed S(s) + O2 (g) = SO2 (g)</span>
Answer:
Dalton's atomic model and Rutherford model
Explanation:
There were differences in the models:
Thompson's experiment showed that atoms contained tiny negatively charged particles called electrons.
On the other hand, Rutherford gold experiment led to the conclusion that the atom is a empty space with tiny, dense and positively charged nucleus.
Dalton thought that atoms were the smallest units of matter that could not be broken down further. This assumption continued to hold until it was later discovered that the atom was composed of subatomic particles.
Answer:
Option 3
Explanation:
Option 3: Instantaneous speed is the speed of an object at a specific time, but average speed is the total distance over the total time. This is why they are called instantaneous and average, because instantaneous is at any one instance and average is the average speed it was moving over the total time which is calculated by the total distance/total time.
Hope this helped!
Answer:
c) the overall reaction order is 1.
Explanation:
The order of reaction is defined as the order in which the particles of the different reagents commission to produce a product. Additionally, the total order of reaction is the sum of the exponents of the concentrations in the law of the reaction rate, since the order depends on the reagent that is analyzed. The order of the reactions is determined experimentally.
Answer:
0.0014 moles is present in 40cm³ of 0.035M of HCl solution
Explanation:
Molarity = 0.035M
V = 40.0mL
1mL = 1cm³
V = 40cm³
0.035 moles = 1000cm³
X moles is present in 40cm³
X = (40 * 0.035) / 1000
X = 0.0014moles
0.0014 moles is present in 40cm³ of solution
