Answer:

Bleach and seawater are identified wrong.

Explanation:

Acids have an pH that is lower than 7 and bases have a pH of higher than 7 and (pH 7 is neutral)

We can observe from the table that bleach has a pH of 13 which is higher than 7 and shows basic characteristics

As for seawater the table shows it has a pH of 8 which is also a base. Therefore the answer is 3rd option "Bleach and seawater should be identified as bases".

1.572x108 Troy oz of silver were used in the us in 1980 how many kilograms is this

Anna71 [15]

Answer: 4873200 kg

Explanation:

Given mass: $1.572\times 10^8$ troy oz

Conversion factor : $1troyoz=0.031kg$

Thus if 1 troy oz weighs in kg = 0.031 kg

$1.572\times 10^8$ troy oz will weigh in kg = $\frac{0.031}{1}\times 1.572\times 10^8=0.04873\times 10^8kg$

Thus there are $0.04873\times 10^8kg$ in $1.572\times 10^8$ troy oz of silver used.
