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 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.
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
Is Bloons additive?
yes it is very additive
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.
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).
What are additive adverse property?
The additive inverse means what undoes adding. The additive inverse of +1 is -1.
What is Production volumes?
production volumes are the amount of volumes producd in a day
What additive is in the blue top?
The additive is sodium citrate
