Answer:
Biologist Rachel Carson made the world aware of the ecological effect of chemical composts and pesticides. Her most popular book, Silent Spring, prompted a presidential commission that generally embraced her discoveries and assisted with molding a developing ecological awareness.
Carson was not against the utilization of synthetic fertilizers or chemicals completely; rather, she thought the overuse was pushing their abuse for its financial increase, to the detriment of the health of the environment.
All individuals have the right to inhale clean air and to be liberated from the danger of poisoning due to chemicals; in this manner, all Americans likewise have an obligation to ensure that the earth is safe and clean.
Answer:
0.744 M
Explanation:
IO⁻⁴(aq) + 2H₂O(l) ⇌ H₄IO⁻⁶(aq)
Kc = 3.5×10⁻²= [H₄IO⁻⁶] / [IO⁻⁴]
First let's<u> calculate the new concentration of IO⁻⁴ at equilibrium</u>:
0.904 M * 26.0 mL / 500.0 mL = 0.047 M = [IO⁻⁴]
Now we can<u> calculate [H₄IO⁻⁶] using the formula for Kc</u>:
3.5×10⁻²= [H₄IO⁻⁶] / [IO⁻⁴]
3.5×10⁻²= [H₄IO⁻⁶] / 0.047 M
[H₄IO⁻⁶] = 0.744 M
Because they do not have the same qualities therefore they are different
Answer:
- <em>Sample X</em>, contains the most heat.
Explanation:
In thermodynamics, the <em>heat content</em> of heat of a system or a substance is described by the term enthalpy.
The heat content (enthalpy) is an extensive property, meaning that it is dependent on the amount of substance.
More substance more heat energy content.
Heat content is also related with the temperature. The higher the temperature the greater the kinetic energy and the higher the heat content.
Since, sample X and sample Y are both at the same temperature of 42°C, this variable does not differentiate the heat content of such samples.
Since, the sample X has more volume than sample Y, as per the previous conclusion that the more substance the more heat energy, you can certainly asses that the former contains the most heat.
