Which is a true statement?

labwork [276]

Answer: B) Particles can be filtered from a suspension.

Explanation: Colloids are solutions with particle size intermediate between true solutions and suspensions. They exhibit tyndall effect that is scattering of light.

Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily.

The particle size in colloids is less and hence they do not settle under the effect of gravity.

A solution can be homogeneous in which the composition is uniform or heterogeneous in which is the composition is not uniform.

What is the volume of an object with a density of 24.5 g/cm³ and a mass of 8.2 g?

vitfil [10]

<u>Answer:</u> The correct answer is option A.

<u>Explanation:</u>

To calculate the volume of an object, we use the formula:

$Density=\frac{\text{Mass of an object}}{\text{Volume of an object}}$

We are given:

Density of an object = $24.5g/cm^3$

Mass of an object = 8.2 grams

Volume of an object = ?

Putting values in above equation, we get:

$24.5g/cm^3=\frac{8.2g}{Volume}$

$Volume=0.33cm^3$

Hence, the correct answer is Option A.

Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu(NO3)2. The balanced chemical equation

Rufina [12.5K]

The mass formed in a chemical reaction is given by stoichiometry law in balanced chemical equation. The mass of silver produced in the reaction is 107. 9 g.

<h3>What is the stoichiometric law?</h3>

The stoichiometric law states that in a balanced chemical equation, the stoichiometric coefficient describes the moles of each compound in a chemical reaction.

The balanced chemical equation for the reaction is:

$\rm Cu\;+\;2\;AgNO_3\;\rightarrow\;Cu(NO_3)_2\;+\;2\;Ag$

From the balanced chemical equation, 1 moles of copper results in 2 moles of silver.

Moles in terms of mass can be given as:

$\rm Moles=\dfrac{Mass}{Molar\;mass}$

Thus, moles of 31. 75 grams copper is:

$\rm Cu=\dfrac{ 31. 75 }{63.5}\;mol\\ Cu=0.5 mol$

The moles of Ag produced can be given from stoichiometric law as:

$\rm 1\;mol\;Cu=2\;mol\;Ag\\0.5 \;mol\;Cu=0.5\;\times\;2\;mol\;Ag\\0.5\;mol\;Cu=1\;mol\;Ag$

The moles of Ag produced is 1 mol.

The mass of a mole of element is equivalent to the molar mass. Thus, the mass of Ag produced in the reaction is 107. 9 g. Hence, option B is correct.

Develop a product by using principles of science to encounter environment related problems

Oxana [17]

It is because we are, this is the first time in human history, where we have technology and science is widely accepted, without being ridiculed by religious figures.
Science can provide us with enough detailed knowledge about nature to solve and prevent environmental problems. ... It is possible to prevent pollution in the future and develop 'clean' industrial processes that have no environmental impacts.
Develop a product by using principles of science to encounter environment related problems
It is currently believed that science and technology can provide effective solutions to most, if not all, environmental problems facing western industrial societies. ... It can therefore be concluded that science and technology have only very limited potential in solving current and future environmental problems.
Ways Technology is Helping the Environment
