Students are investigating the differences in open and closed systems. They heated 2 containers of water. They recorded their re

sults in the tables shown.
Two tables.Short description, Two tables.,Long description,
Container 1
Before After Mass of Container and Contents in grams 200 150 Volume of Water in milliliters 100 50
Container 2
Before After Mass of Container and Contents in grams 200 200 Volume of Water in milliliters 100 50
Question

Answer options with 4 options
A.
Container 1 is a closed system because a gas was produced. Gases do not have mass.
B.
Container 1 is an open system because a gas was produced. Gases make things lighter.
C.

Container 2 is a closed system because the mass did not change even

though the volume changed.

<h3>What is a Closed system?</h3>

A closed system is the type of system which prohibits the transfer of

matter in and out the system.

In a closed system , the mass of the matter present is always the same

regardless of the changes which occurred which is why option D is the

most appropriate option.

The first-order reaction, so2cl2 → so2 + cl2, has a rate constant equal to 2.20 × 10-5 s-1 at 593 k. what percentage of the init
Svetradugi [14.3K]
For the 1st order reactions,rate constant (k) is mathematically expressed as

k = \frac{2.303}{t}log \frac{Co}{Ct}
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 = \frac{2.303}{7200}log \frac{100}{Ct}
∴ log\frac{100}{Ct} = 0.06877
∴, \frac{100}{Ct} = 1.1716
∴, Ct = 85.35%

Thus, <span>85.35 % of the initial amount of SO2Cl2 will remain after 2.00 hours.</span>

The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.
Nostrana [21]

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 .

A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper
natali 33 [55]

Answer:

<h2>Density = 8.96 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass of copper = 89.6 g

volume = 10 cm³

Substitute the values into the above formula and solve

That's

Density =  \frac{89.6}{10}

We have the final answer as

<h3>Density = 8.96 g/cm³</h3>

Hope this helps you
