Answer:
The answer for the first problem is: C₆N₁H₁₁O₁ or C₆NH₁₁O
Explanation:
Nylon composition: Mass Divide by the atomic mass
Carbon 63.68 % 63.68 g 63.68/ 12 = 5.3
Nitrogen 12.38 % 12.38 g 12.38/14 = 0.88
Hydrogen 9.8% 9.8 g 9.8/1 = 9.8
Oxygen 14.14% 14.14 g 14.14/16 = 0.88
We choose the lowest number that is 0.88 for nitrogen and oxygen and divide the four results by this number
Carbon 5.3/0.88 = 6
Nitrogen 0.88/0.88 = 1
Hydrogen 9.8/0.88 = 11.1 = 11
Oxygen 0.88/ 0.88 = 1
Then the empirical formula has this coefficients
C₆N₁H₁₁O₁ or C₆NH₁₁O
Answer:
x=4
Explanation:
distribute-
2x+15x-21=47
combine like terms-
17x-21=47
add 21 to both sides
17x=68
Divide 17 from both sides
x=4

<h3>
The Law of Conservation of Mass</h3>
<em>Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.</em>
<em>The Law of Conservation of Matter also states that the matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.</em>

Answer:
Living Space get food or nutrients, water, and shelter. No matter where an organism lives, it must provide what it needs to survive.
Explanation:All organisms need a place to live, and store energy to take care of itself.
Approximately 26,000 years but i guess the closest would be 23,000 I hope this helps! ^^;
