Explanation:
Hello,
In this case, given the mathematical definition of molar concentration as the moles of solute divided by the liters of solution:
We can easily compute it by firstly computing the moles of sugar by using its molar mass:
After that, we compute the concentration by realizing 259.8 mL equals 0.2598 L:
Or just:
Considering molar units as mol/L
Best regards.
Q=heat and Q=m*c*dekta(temp)
So we have
Q= 100g*4.184*50=20920J of heat energy
Q= 100g * 0.397* 50= 1985J of heat energy
So the water requires more energy and this is due to the higher heat capacity value of water than the metal sample
Please help me out and rate Brainliest if my answer helped you understand the concept and how to solve!! Any questions please just ask! Thank you so much!!
The balanced reaction is:
MnO2<span>(s) + 4HCl(aq) → Cl2(g) + MnCl2(aq) + 2H2O(l)
</span>
We are given the amount of hydrochloric acid to be used for the reaction. This will be the starting point for the calculations.
1.82 mol HCl ( 1 mol Cl2 / 4 mol HCl) = 0.46 mol Cl2
Therefore, 0.46 mol of chlorine gas is produced for the reaction of hydrochloric acid and manganese oxide.
This is true. You don’t want them to be bored
