<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>
Use the percent as mass in g
Mass g) --> g/mol
K, B and H molar mass from periodic table
54.93 g K x (1 mol K/ 39.10 g K) = 1.405 mol K
38.73 g B x (1 mol B/ 10.81 g B) = 3.583 mol B
6.34 g H x (1 mol H/ 1.008 g H) = 6.290 mol H
Divide all three answers by the smallest value and you will get
1.000 mol K
2.550 mol B
4.477 mol H
now multiply these three answers by a number that will make all a whole number or (a number with a 9 as the first decimal point)
so multiply by 2
2 mol k
5 mol B
and 9 mol H
E.F. = K2B5H9
Answer is D
Sorry for bad explanation!!!!!!
Physical weathering is caused by physical processes such as changes in temperature, freezing and thawing, and the effects of wind, rain and waves.

Explanation:
Step 1: Write the balanced "molecular" equation:

Step 2: H₂S is written in molecular form. Consult the solubility and net ionic equation rules on the information page to determine which of the other substances will dissociate:

yes no yes
Step 3: Dissociate all soluble salts, strong acids, and strong bases (except calcium hydroxide). Leave together all "not soluble" salts and weak acids or bases:

Step 4: Cross out "spectator ions" that appear on both sides of the reaction (these ions do not participate in the chemistry) and rewrite the "net" reaction using the smallest possible coefficients:
