The specific heat capacity of ethanol is 2.46 joules per gram.
Now, we may use the equation:
Energy = mass * specific heat capacity * change in temperature
Here we may substitute:
mass = density * volume
Energy = density * volume * specific heat capacity * change in temperature
720 = 0.789 * 35 * 2.46 * ΔT
ΔT = 10.6
The final temperature will be
20 + 10.6
= 30.6 °C
Hope this helps! Also if it’s hard to read just look up “ what is a protein coat” pretty easy right?
Overfishing is an example of human impact on biodiversity.
In simple terms, overfishing means that the sea animals hunted for food ( fishes, crustaceans, mollusks etc.) in a year are hunted in numbers greater than the number of newborn individuals of that species in that year. This means that the populations of these animals do not have the time to regrow their numbers.
This results in a dramatic decline of populations of many marine animals.
Animals get their food by preying on other species or scrounging for scraps they can find. Some eat other animals and some eat plants.
Plants get their food by absorbing minerals and water from the ground and absorbing carbon dioxide from the air through their leaves. They then also absorb sunlight and all of those components are made into food for the plant. Simple answer is through photosynthesis.
Molarity = Moles / Liters! So in this instance, if you have 0.45 moles of NaCl, and we convert 300.0 mL to 0.3 L, we would plug in M = 0.45/0.3. The answer would be 1.5 M NaCl!
