Colors of vacutainers?
Vacutainers come in a variety of colors to denote the type of additive or treatment applied to the blood sample. Common colors include red (no additive), lavender/purple (EDTA additive), light blue (sodium citrate additive), green (heparin additive), and gray (fluoride oxalate additive). Each color signifies a specific purpose in preserving or treating the blood sample for laboratory testing.
Is trisodium phosphate allowed as a food additive by the FDA?
Yes, trisodium phosphate is allowed as a food additive by the FDA.
How many water vapour can be produced from 10 volume of hydrogen and 5volume of oxygen?
The reaction between hydrogen and oxygen to form water is given by the equation: 2H2 + O2 -> 2H2O. This means that 2 volumes of hydrogen react with 1 volume of oxygen to produce 2 volumes of water vapor. Therefore, from 10 volumes of hydrogen and 5 volumes of oxygen, 10 volumes of water vapor can be produced.
Is tripotassium phosphate commonly used as a food additive in processed foods?
Yes, tripotassium phosphate is commonly used as a food additive in processed foods.
What is gay-lussac's law of combination volumes?
The ratio between reactant gases and product gases are simple integers.
What does it mean when it says The volumes are additive?
When it says that volumes are additive, it means that the total volume of a system is equal to the sum of the volumes of its individual components. This concept is commonly applied in physics, chemistry, and engineering when dealing with mixtures or composite materials. By understanding that volumes are additive, one can accurately calculate the overall volume of a system based on the volumes of its parts.
Why is volume additive?
Volume is additive because when multiple three-dimensional objects are combined, their individual volumes sum to create a total volume. This principle holds true regardless of the shapes involved, as long as they do not overlap. For example, if you have two separate containers with known volumes, the total volume of the combined containers is simply the sum of their individual volumes. This additive property is fundamental in geometry and is essential for calculations in various fields, including architecture, engineering, and science.
Why don't chemist use percent by volume to prepare and describe many solutions they use?
some liquid volumes are not additive, leading to potentially confusing final solution volumes.
Why do you add the mass of water to the mass of salt dissolved in it to find the mass of the solution?
Nope. The volume does not change but the density of the mixture increases. No, the volume of water is straight forward to measure but salt as a solid composed of small crystals has an aparent volume wich includes many voids filled with air. Assuming you have measured properly the two components volumes adding them will provide you with what is known as ideal volume, but reality deviates from this linear additive values. Especially with electrolytes such as sodium chloride the final volume differs from ideal addition values expected.The topic has been extensively studied and explained by science, look for partial molar volumes concept and equations in basic physical chemistry textbooks. Remember that mass is conservative and that density is defined as mass per unit volume, say grams per milliliter. It is right to say that density changes ( measuring densities is the way to construct partial molar volumes graphs), since mass is conservative the only way to get density changes is by increasing or decreasing volumes. Solutions are classified as ideal (additive volumes) or non ideal (non additive volumes). Hope this solves your question.
What is additive volume?
Additive volume refers to the cumulative volume of individual components in a mixture, where the total volume is the sum of the volumes of the parts, regardless of how they interact. This concept is often applied in fields like chemistry and materials science, where it can help predict the behavior of mixtures. However, in some cases, such as with gases or certain liquids, the actual volume may differ due to interactions between the components, leading to deviations from the additive volume assumption.
Why extensive property are additive?
Extensive properties are additive because they depend on the quantity of material present in a system. When two or more systems are combined, the total extensive property of the resulting system is the sum of the extensive properties of the individual systems. For example, if you combine two portions of a substance, the total mass or volume is simply the sum of the masses or volumes of the two portions. This additive nature reflects how extensive properties scale with the size of the system.
Is 1 an additive identity?
no 1 is not an additive identity
Is FeSO4 an additive or preservative?
additive
What are the basic volumes?
basic volumes are volumes that are original
Why don't chemists use percent by volume to prepare and describe many solutions they use?
Chemists typically use percent by weight or molarity to prepare and describe solutions because these measures are more accurate and reflective of the actual concentration of solute in the solution. Percent by volume can fluctuate with temperature changes and can be affected by differences in the volumes of the solute and solvent, making it less precise for analytical purposes.
Is Bloons additive?
yes it is very additive
What is the additive inverse of .5?
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
