What is the rule for adding and subtracting sig figs? When you add or subtract, you assign significant figures in the answer based on the number of decimal places in each original measurement. When you multiply or divide, you assign significant figures in the answer based on the smallest number of significant figures from your […]

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming […]
What are observable and measurable properties of matter?
What are observable and measurable properties of matter? Observable properties include measurements like height, weight, temperature, and the volume of an object. Explanation: Observable properties are things we can use our five senses to determine, the measurable properties in the question need a tool like a thermometer or a ruler to determine. What are the […]

Did Antarctica used to be hot?
Did Antarctica used to be hot? Climate change Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from 1957 to 2006. Did […]
What happens during the formation of a solution?
What happens during the formation of a solution? In order to form a solution, the solute must be surrounded, or solvated, by the solvent. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds. What are the factors affecting solution? Factors affecting solubility Temperature. Basically, solubility increases with […]
What element has 40 protons and 53 neutrons?
What element has 40 protons and 53 neutrons? Zirconium – Element information, properties and uses | Periodic Table. What if there were no electrons? You would become plasma as there are no electrons to form molecules. You wouldn’t exist unless you were plasma. Meaning you would die. Nothing other than plasma would exist in such […]
How the concentration affects the rate of reaction?
How the concentration affects the rate of reaction? Concentration. If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction […]
Can a vector have a component equal to zero?
What is the difference between an intensive and extensive property?
What is the difference between an intensive and extensive property? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Which list […]
