8 0

Explanation:

The whole process of titration involves finding the concentration of a solution (usually an acid or base) by adding (titrating) it to a solution(acid or base) with a known concentration.

The solution of unknown concentration (the analyte) is usually placed in an flask, while the solution of known concentration (titrant) is placed in a burette and slowly added to the flask.

For a science experiment Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolv
My name is Ann [436]

Answer: Marcia made a more concentrated salt solution.

Explanation:

Marcia used 1 kg of salt, which the exercise tells us is 2.2 lb.

She dissolved it in 3L of water, so we have to find out how much that is in pints. We do that using cross multiplication.

If 1L equals 2.11 pints, then

xpints / 3L = 2.11pints / 1L, so

xpints = (3L . 2.11pints) / 1L = 6.33 pints

Now we know she dissolved 2.2lb in 6.33 pints of water. We use cross multiplication again to find out how much salt she would have in 10 pints, so we can know how concentrated it is compared to Bobby's solution, which is 10 pints.

xlb / 10pints = 2.2lb / 6.33pints

xlb = (10pints . 2.2lb) / 6.33pints = 3.47lb

So Marcia has a concentration of 3.47lb per 10 pints, whereas Bobby only has 3lb per 10 pints.

Kaia, a chemical engineering graduate, has documented all titration procedures in her project report. She refers to this report
vagabundo [1.1K]

Answer:

The correct option is;

d. Explicit knowledge

Explanation:

Explicit knowledge is the knowledge that can be easily articulated documented stored in a retrieval system accesses, transmitted and shared with others

Tacit knowledge is the skill developed by an individual based on actual experience such that such knowledge comprise of both facts and perspectives

Hence explicit knowledge and tacit knowledge are complementary

The operations performed by Kaia include documentation, storing in a retrieval system (her project report) and accessing what she documented, this is an example of explicit knowledge.
