Answer:
<h2>mass = 1102.50 g</h2>Explanation:
The density of a substance can be found by using the formula
Making mass the subject we have
<h3>mass = Density × volume</h3>From the question
Density of silver = 10.50 g/cm³
Volume = 105 cm³
Substitute the values into the above formula and solve for the mass
That's
mass = 10.5 × 105
We have the final answer as
mass = 1102.50 g
Hope this helps you
Answer:
Second order
Explanation:
Given that:
When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.
From the integration method for the second order of reaction.
Suppose that:
rate = k₂[A]²
∴
Therefore, a plot of the linear function versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be
The linear plot for a second order reaction can be seen in theimage attached below.
Answer:
The initial volume of Ne gas is 261mL
Explanation:
This question can be answered using Ideal Gas Equation;
However, the following are the given parameters
Initial Pressure = 654mmHg
Finial Pressure = 345mmHg
Final Volume = 495mL
Required
Initial Volume?
The question says that Temperature is constant;
This implies that, we'll make use of Boyle's law ideal gas equation which states;
Where represent the initial pressure
represent the final pressure
represent the initial temperature
represent the final temperature
Substitute these values in the formula above;
Divide both sides by 654
(Approximated)
<em>The initial volume of Ne gas is 261mL</em>
