Answer:

Gas

Explanation:

The law of mass conservation states that the total mass of the reactants should be equal to the total mass of the products, that is, the mass should be conserved.

There are specific occasions when students might think that their findings do not follow the law. This is usually the case when some specific gas is evolved in a reaction.

The problem is that when gas evolves, if it's not soluble in a given solution, it escapes it into the surroundings and it seems at first that the mass of the products is actually lower than expected.

We would need to collect the gas evolved and calculate its mass in order to add it to the mass of the remaining products in order to verify the law in such cases.

The mechanism for producing a concentrated urine involves all of the following except
avanturin [10]

Answer:

The correct answer is "obligatory water reabsorption in the proximal convoluted tubule".

Explanation:

The mechanism for producing concentrated urine cannot include the obligatory reabsorption of water in the proximal convoluted tubule since this process is part of the nephron, the system that filters the blood. Glucose and amino acids are reabsorbed almost entirely, as are approximately 70% of filtered potassium and 80% of bicarbonate.

worty [1.4K]

Answer:

The answer is: the body contains chemicals called buffers that resist changes in pH

When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.
