Answer:
Explanation:
Hello there!
In this case, according to this titration problem, it is possible to note there is a 1:3 mole ratio of CuFeS2 to CuCl2; it means that we can use the following equation:
Thus, by introducing the mass and molar mass of the former and the volume and concentration of the latter, we write:
Regards!
Fecl3 has a RFM of 56 + (35.5 * 3) = 162.5
so find out its moles 16.5 ÷ 162 5 = aprox. 0.1M
then there is a 1 : 3 ratio so 0.1 * 3 = 0.3
then times that by the avogado constant which is 6.02×10^23
0.3 × 6.02×10^23 = ans
hope that helps
Answer:
The new volume of the gas is 21 L.
Explanation:
Volume of a gas is inversely proportional to its pressure at constant temperature such that,
or
We have,
It is required to find V₂. Using above law or Boyle's law such that :
So, the new volume of the gas is 21 L.
The correct answer for this question is 'False'
Environmental science is not the study of the earth's natural hazards
What is Environmental science?
Environmental Science is the study of physical, chemical, biological components of earth's natural environment they include air, water etc.,
The Environmental science closely studies the human impact on the earth's environment.
This field of science also helps us to know about how science effects our environment.
And the 3 main aspects of Environmental science are:
To understand the interaction between humans and environment
To understand how natural world works
To Find a way to deal with the environmental problems to live sustainably.

Use the ICE table approach as solution:
PbSO₄ --> Pb²⁺ + SO₄²⁻
I - 0 0
C - +s +s
E - s s
Ksp = [Pb²⁺][SO₄²⁻]
1.82×10⁻⁸ = s²
Solving for s,
s = <em>1.35×10⁻⁴ M</em>
