Answer:
C. 1 cubic foot of loose sand
Explanation:
For many objects having equal volume , surface area will be maximum
of the object which has spherical shape .
But when a sphere is broken into tiny small spheres , total surface area of all the small spheres will be more than surface area of big sphere .
Hence among the given option , surface area of loose sand will have greatest surface area . Loose sand is equivalent to small spheres .
Mols CuSO4 = M x L = 1.50 x 0.150 = 0.225
<span>mols KOH = 3.00 x 0.150 = 0.450 </span>
<span>specific heat solns = specific heat H2O = 4.18 J/K*C </span>
<span>CuSO4 + 2KOH = Cu(OH)2 + 2H2O </span>
<span>q = mass solutions x specific heat solns x (Tfinal-Tinitial) + Ccal*deltat T </span>
<span>q = 300g x 4.18 x (31.3-25.2) + 24.2*(31.3-25.2) </span>
<span>dHrxn in J/mol= q/0.225 mol CuSO4 </span>
<span>Then convert to kJ/mol
</span>
The properties of the electrons of an atom are determined in large part by the number of protons presented in the nucleus of the atom
Answer:
See explanation.
Explanation:
Hello!
In this case, since the main molecular reaction that is taken place in the beaker is:
In such a way, we understand that one breaker contained silver nitrate and the other one barium iodide. Thus, the complete molecular equations turns out:
Now, for the complete ionic equation, we just ionize the aqueous species:
Finally, for the net ionic equation we cancel out barium and nitrate ions as the spectator one because they are both sides on the equation:
Best regards!
<h3><u>Answer;</u></h3>
Atomic particles
The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.
<h3><u>Explanation</u>;</h3>
- Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
- <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
- Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
