Answer:
Depends, but in most cases, 2.
It's best to use as many digits as possible to keep it accurate.
Explanation:
This varies between teachers, as most schools go with 2 decimal places.
This is something that depends in your situation.
You technically want as many decimals as possible to keep it as accurate, but most people stick with 2.
I personally do 3, and commonly do 5 sometimes.
The answer is <span>C. Glucose is an organic molecule.
Glucose is carbohydrate so it cannot be a protein or a nucleic acid. It is an organic molecule. The organic molecule is compound consisting of carbon to which are attached hydrogen, oxygen, and nitrogen. Since, g</span><span>lucose is a simple sugar made up of carbon, hydrogen, and oxygen, it, as well as any other carbohydrate, is the organic molecule.</span>
Answer:
The correct answer is - C: Energy is neither created nor destroyed, but continually transformed into new forms of energy.
Explanation:
Conservation of energy is the first law of thermodynamics that says that energy is neither generated nor destroyed, can only be transformed from one form to another form continuously. That means no matter what the condition the amount of energy will remain the same, only form will be changed.
For instance, if an electric current will pass through a circuit of a light bulb the electrical energy present in the circuit will transfer into heat and light energy, The amount will remain constant but the one form change to another.
The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7
<h3>What is
pOH scale?</h3>
Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.
The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.
The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.
