Answer:
The wooden spoon.
Explanation:
The wooden spoon won't be as hot as a metal spoon its logic and a correct answer.
Answer:
8.4) 27.1 cm³
8.5) 0.217 mol/dm³
Explanation:
Please see attached picture for full solution.
8.4) Since the results from titrations 3-5 are within 0.10cm³ from each other, these 3 results are concordant.
8.5) Find mol of sulfuric acid to find mol of NaOH using mole ratio. Equation has already been balanced for you, so mole ratio of NaOH to H2S04 is 2:1. To find concentration of NaOH, divide the number of moles by the volume in dm³ since the units for concentration is mol/dm³, which you can think of as the number of moles of NaOH in a dm³ of solution.
1 dm³ = 1000cm³
Thus, 1cm³= 1/1000 dm³
It would be:
B. HCl
A metal will react with an acid to form a salt (MgCl2) and H2.
It will be different according to how each of them is easily warmed up when using thermal energy.
Water heats at 100 celsius and all the other solutions have slightly different boiling points
