Answer:
Titrations. Because a noticeable pH change occurs near the equivalence point of acid-base titrations, an indicator can be used to signal the end of a titration. When selecting an indicator for acid-base titrations, choose an indicator whose pH range falls within the pH change of the reaction.
Hope it helped!!
Chemical change because it cannot be reversed
Answer:
atoms
Explanation:
for sugar to dissolve in water hydaration must be equal to or greater than the lattice energy or molecular forces so when the molecular forces breaks new atoms are formed for recombination in new compound
Answer:-
1440 cases
Explanation: -
We are told that 1 pallet = 45 bundles.
We are also told that 1 bundle = 32 cases.
We need to find how many cases are there in 1 pallet.
1 pallet = 45 bundles (First conversion factor)
= 45 x 32 cases (second conversion factor)
=1440 cases
Thus we see that 1 pallet has 1440 cases. We needed to use two conversion factors for this, first to convert pallet to bundle and second to convert bundle to cases.
