Answer:
Quarts of blood = 72000
Quarts of urine = 720
Explanation:
<h3><u>Given</u>;</h3>
- Each day, the average person's
- kidneys filter around 200 quarts of blood.
- About 2 quarts of urine is produced in the
- process.
<h3><u>To </u><u>Find</u>;</h3>
- In one year the average person's kidney filter quarts of blood and quarts of urine.
Here, we know that
1 year = 365 days
For blood
200 × 365 = 72000
For urine
2 × 365 = 720
Thus, The average person's kidney filters 72000 quarts of blood and 720 quarts of urine.
M<span>olar mass Hg = 200.5920g/mol </span>
<span>Hg = 24.1/200.5920 = 0.120mol </span>
<span>234.32K liquid to 25C (298.15K) liquid </span>
<span>h = (0.120)(28.0)(298.15 - 234.32) = 214.4688 J </span>
<span>234.32K liquid to 234.32K solid </span>
<span>h = (0.120)(2.29) = 0.2748 kj </span>
<span>total heat = 0.2145 + 0.2748 = 0.4893 kJ</span>
Let's hope she didn't watch it without me or i will never be speaking to her again :))
Answer:
Antoine Lavoisier and Johann Wolfang Döbereiner organized the elements based on properties such as how the elements reacts or whether they are solid or liquid.
Explanation:
The periodic table of the elements as we have it today was developed as a result of the work of several notable centuries who lived centuries apart, all of who made notable contributions to development of the modern periodic table in use today.
In 1789, Antoine Lavoisier, a French Chemist provided a definition of elemets which he defined as a substance whose smallest units cannot be broken down into a simpler substance. He further grouped the elements into two as metals and nonmetals.
In 1829, German physicist Johann Wolfang Döbereiner arranged elements in groups of three in increasing order of atomic weight and called them triads. His arrangement owasf elements into triads was based on his observation of similarities in physical and chemical properties of certain elements.
John Newlands, a British Chemist was the first to arrange the elements into a periodic table with increasing order of atomic masses.
In 1869, Russian chemist Dmitri Mendeleev developed a periodic table which provided a framework the modern periodic table. He arranged the elements according to their atomic weight, leaving gaps for elements that were yet to be discovered.
The modern periodic table arranges elements based on increasing atomic number.
