Answer:
The necessary equations necessary are explained in each step in the solution.
Explanation:
For conversion of methanol gas at 65°C to -112°C
the equations would be as follows,
step 1 : gas at 65°C to liquid at 65°C
q = n(-37 kJ/mol)
step 2 : liquid at 65°C to liquid at -94°C
q = n(81.1 J/mol°C), where dT is negative
step 3 : liquid at -94°C to solid at -94°C
q = n(-3.18 kJ/mol)
step 4 : solid at -94°C to solid at -112°C
q = n(48.7 J/mol°C), where dT is negative
<span>These particular substances produce hydroxide ions (OH−)
in aqueous solutions, and are thus classified as Arrhenius bases. For a
substance to be classified as an Arrhenius base, it must produce hydroxide ions in an aqueous solution. In order to do so, Arrhenius believed the base must contain hydroxide in the formula.</span>
Answer: A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. ... In the food chain, energy is transferred from one living organism through another in the form of food. In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass rightarrow→right arrow cow rightarrow→right arrow human. But what if you had lettuce on your hamburger? In that case, you're also part of a food chain that looks like this: lettuce rightarrow→right arrow human
Explanation:
<span>Water is vital to the existence of plant life. Not only do plants use it to keep their cells from drying out, but they need water to move nutrients and raw materials throughout their systems to areas where photosynthesis and seed production take place. When water stress occurs, whether caused by drought or root impairment, many invisible processes are affected.</span>
a. Organic: C₁₀H₁₆KNO₉S₂; (CH₃)₄As₂; C₆H₁₂O₆
b. Inorganic: NaAsO₂; HSiCl₃; (BiO)₂CO₃; H₂P₂O₇; H₂O; CO₂
Compounds containing <em>both C and H</em> are organic.
Compounds that are <em>not organic</em> are inorganic.
