The mass would still be the same 25.0 g but the volume would be bigger
The power plant would be Mitochondrion because it makes ATP for the cell. Hope this helps!
Answer:
262 ppm of Na₃PO₄
Explanation:
In a dilution, the concentration of the initial solution is decreased. When you take 5.00mL of the solution that is diluted to 25.0mL The solution is diluted 25/5 = <em>5 times</em>
If you make another two serial dilutions the final solution wil decrease its concentration 5*5*5 = 125 times
As original solution containing 0.200 M of Na3PO4, the final solution will have a concentration of:
0.200M / 125 = <em>1.6x10⁻³M</em>
Molarity is defined as the ratio between moles and liters. 1.6x10⁻³ moles of Na3PO4 in 1L are:
1.6x10⁻³mol ₓ (164g/mol) = 0.262g Na₃PO₄ / L
Assuming density of Na3PO4 as 1g/mL the concentration of the solution is:
0.262mL Na₃PO₄ / L
As 1mL = 1000μL:
262μL Na₃PO₄ / L
μL of solute per L of solution is equal to ppm, that means the solution has:
<h3>262 ppm of Na₃PO₄</h3>
Answer:
metal can hold heat keep it near fire
Answer: a precipitate.
Justification:
When two liquids are mixed together, their constituents may react chemically, forming new products whose chemical properties are different from those of the original constituents of the mixtures.
Then, some of the products formed may be insoluble in the mix. In this case is when the precipitate (solid that cannot stand in the solution) will get formed.
The formation of a precipitate is a clear signal that a chemical reaction has taken place between some constituents (elements or compounds) of the mix.
One example of this situation is the combination of a solution of baking soda, NaHCO₃(aq), and a solution of calcium chloride, CaCl₂ (aq).
Those two solutions are clear, and when combined will form a solid (precipitate) which is calcium carbonate, CaCO₃ (s). The calcium carbonate precipitates because it is not soluble in the mix.
