Answer: The concentration of the diluted solution is 1.566M.
Explanation:
The dilution equation is presented as this: .
·M= molarity (labeled as M)
·V= volume (labeled as L)
·s= stock solution (what you started with)
·d= diluted solution (what you have after)
Now that we know what each part of the formula symbolizes, we can plug in our data.
We cannot leave it like this because the volumes must be in Liters, not milliliters. To convert this, we divide the milliliters by 1000.
Now that we have the conversions, let's plug them into the equation.
The only thing that we need to do now is actually solving the answer.
From the work shown above, the answer is 1.566M.
I hope this helps!! Pls mark brainliest :)
Answer:
Explanation:
In this case, we can start with the <u>formula of Platinum (II) Chloride</u>. The cation is the atom at the left of the name (in this case ) and the anion is the atom at the right of the name (in this case
). With this in mind, the <u>formula would be</u>
.
Now, if we used <u>metallic copper</u> we have to put in the reaction only the <u>copper atom symbol</u> . So, we have as reagents:
The question now is: <u>What would be the products?</u> To answer this, we have to remember <u>"single displacement reactions"</u>. With a general reaction:
With this in mind, the reaction would be:

Answer:
\large \boxed{\textbf{609 kJ}}
Explanation:
The formula for the heat absorbed is
q = mCΔT
Data:
m = 2.07 kg
T₁ = 23 °C
T₂ = 191 °C
C = 1.75 J·°C⁻¹g⁻¹
Calculations:
1. Convert kilograms to grams
2.07 kg = 2070 g
2. Calculate ΔT
ΔT = T₂ - T₁ = 191 - 23 = 168 °C
3. Calculate q
