Answer:
did you ever get the answer
A ph higher than 7 is basic so you can eliminate a. The indicator can be used to measure both acids and bases so you can eliminate c. Hydrogen ions are from acids, so the answer is that the powder decreased the hydrogen ions in the water.
Answer:
The weight of body is 1.3040 gram.
Explanation:
Given that,
The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws.
Suppose a crab with a body weight of 1.8 gram has claws weighing 1.1 gram.
Estimate the weight of a fiddler crab with claws weighing 0.85 gram.
Determine the weight of crab body
We need to calculate the value of proportional constant



Put the value into the formula


We need to calculate the crab weight

Here, x = 0.85 g
Put the value into the formula


Hence, The weight of body is 1.3040 gram.
