Here's link to the answer:
bittuly/3a8Nt8
Explanation:
For the 1st order reactions,rate constant (k) is mathematically expressed as
k =

where, t = time
Co = initial conc. of reactant
Ct = conc. of reactant after time 't'
Given: k = <span>2.20 × 10^-5 s-1, t = 2 hours = 7200 s
Therefore, we have
</span>2.20 × 10^-5 =

∴

= 0.06877
∴,

= 1.1716
∴, Ct = 85.35%
Thus, <span>
85.35 % of the initial amount of SO2Cl2 will remain after 2.00 hours.</span>
Answer:
False.
Explanation:
Rate of reaction also depends on the number of collision that is being happening in reacting molecules. So concentration of the reactants is also important to decide the rate of reaction.
The rate of reaction is dependent on the concentration as well.
As the concentration of reactants decreases with time number of collisions also decreases .
Bacteria, virus, fungi, and protists are the four pathogens.
Answer:
<h2>Density = 8.96 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of copper = 89.6 g
volume = 10 cm³
Substitute the values into the above formula and solve
That's

We have the final answer as
<h3>Density = 8.96 g/cm³</h3>
