Why did humans overhunt the Caribbean monk seal to extinction?

Louie drinks a bottle of a water even though he is not thirsty. As a result, what will the body do to maintain homeostasis?

drek231 [11]

<span>Having too much water in the body could cause so much complications; just as having too little can be dangerous. In each of these scenarios the body tries to maintain equilibrium through a process called homeostasis. Homeostasis depends on many variables, such as body temperature and body fluid being kept within certain pre-set limits. The essence of homeostasis is maintain bodily functions and metabolism at equilibrium state. If Loiue takes in so much water in a very hot atmosphere or during summer even though he's not thirsty, his body would have to get rid of the excess water by sweating. On the other, during winter, or in a cold environment Loiue's body would have to get rid of excess water by urinating frequently.</span>

Left to Right

<u>Chemistry</u>

<u>Atomic Structure</u>

Reading a Periodic Table
Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

3.45 g KCl

<u>Step 2: Identify Conversions</u>

Molar Mass of K - 39.10 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of KCl - 39.10 + 35.45 = 74.55 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 3.45 \ g \ KCl(\frac{1 \ mol \ KCl}{74.55 \ g \ KCl})$
Multiply/Divide: $\displaystyle 0.046278 \ mol \ KCl$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.046278 mol KCl ≈ 0.0463 mol KCl

1) What is the mass of 6.2 mol of K2CO3?

lorasvet [3.4K]

Answer:

$\boxed {\boxed {\sf 856.8648 \ grams \ of \ K_2CO_3}}$

Explanation:

To convert from moles to grams, we must find the molar mass.

1. Molar Mass

First, identify the elements in the compound. K₂CO₃ It has potassium, carbon, and oxygen. Find these elements and their masses on the Periodic Table.

K: 39.098 g/mol
C: 12.011 g/mol
O: 15.999 g/mol

Note the subscript of 2 after K and 3 after O. We must multiply oxygen's molar mass by 2, then oxygen's by 3, and add carbon.

2(39.098 g/mol) + 3(15.999 g/mol) + 12.011 g/mol= 138.204 g/mol

2. Convert Moles to Grams

Use the molar mass as a fraction.

$\frac {138.204 \ g \ K_2CO_3}{1 \ mol \ K_23CO_3}$

Multiply by the given number of moles: 6.2

$6.2 \ mol \ K_2CO_3 *\frac {138.204 \ g \ K_2CO_3}{1 \ mol \ K_23CO_3}$

$6.2 *\frac {138.204 \ g \ K_2CO_3}{1 }$

$6.2 * {138.204 \ g \ K_2CO_3}$

$856.8648 \ g \ K_2CO_3$

There are <u>856.8648 grams</u> of potassium carbonate in 6.2 moles.

Is calcium disodium ionic or covalent?

Nostrana [21]

Calcium disodium is ionic. When you look at the periodic table, you can see that they are in the same group and that they re both metals. an ionic bond is formed by two or more nonmetals and a covalent bond is formed by two or more nonmetals.
