Answer: Meniscus
Explanation: There is a condition on reading volumes. For concave meniscus read volume in the lower part and for convex meniscus read volume at the upper part.
Answer:
Density dependent factors include disease, competition, and predation. Density dependant factors can have either a positive or a negative correlation to population size
Explanation:
hope this helps ;)
It helps to map out how you will navigate through your unit analysis problem before setting it up.
You are given moles and need grams. What can be used as a conversion factor from moles to grams? Molar mass. We are working with aluminum, so we will need the molar mass of aluminum. My Periodic Table tells me the molar mass of aluminum is approximately 27 g/mol. Now we are ready to set up the unit analysis.

Moles must go on the bottom so that they cancel. Notice how our number of significant figures is 2, so the answer must round to 16 g Al.

Answer:</h3>
16 grams
When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now write the chemical equation
CH₃COOH + CH₃OH ⇄ CH₃COOCH₃ + H₂O
Here
CH₃COOH is Ethanoic acid (Acetic acid)
CH₃OH is Methanol (Methyl Alcohol)
CH₃COOCH₃ is Methyl ethanoate (Methyl Acetate)
H₂O is water
Thus from the above conclusion we can say that When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.

Answer:
changes from liquid to gas at 2,862°C
Explanation:
chemical changes are where you can't go back or change what's made. you can't change it after it's a gas.
