<h2>Answer:</h2>
The mass of the system will remain the same if there is no conversion of mass to energy in the reaction.
<h3>Explanation:</h3>
- If the system is closed, then according to the law of mass conservation the mass of the reaction system will remain the same.
- <u><em>Law of conservation of the mass: In simple words, it is described as the mass of a closed system can never be changed, it may transfer from one form to another or change into energy.</em></u>
- But if the reaction involves energy transfer like heat or light production, in this case, the mass can be changed.
According to the equation of molarity:
Molarity= no.of moles / volume per liter of Solution
when we have the molarity=0.58 M and the beaker at 150mL so V (per liter) = 150mL/1000 = 0.150 L
by substitution:
∴ No.of moles = Molarity * Volume of solution (per liter)
= 0.58 * 0.150 = 0.087 Moles
An apparatus called a centrifuge is used to separate solids from the aqueous portion of blood. A sample of the blood is transferred to a small vial or test tube and this vessel is then placed into the centrifuge. The machine works by rotating the sample around a fixed axis, spinning it in a circle, and this results in a strong force being applied to the sample that is perpendicular to the axis of the spin. This force is called the centripetal force and this centripetal acceleration causes the most dense particles in the blood to move outward in the radial direction. This results in the less dense materials being displaced by the more dense materials. Once the sample vessel is retrieved from the centrifuge, the sample will be separated into layers, such that the solids are found at the bottom of the vessel. The less dense materials such as the water will be found at the top of the vessel.
Acid more H3O+ than OH-
Base less H3O+ than OH-
Livor mortis refers to the bluish-purple discoloration (lividity) under the skin of the lower body parts due to gravitation of blood after death. ... Dark pinpoint spots (Tardieu spots) are seen when capillaries rupture due to increased gravitational pressure (e.g. in the legs of a hanged person)
