Osmium is the densest<span> element on earth. It is a hard, weak, pale blue white move metal in the platinum aggregate that is found as a follow component in amalgams, generally in platinum minerals. Osmium is the densest normally happening component, with a thickness of22.59 g/cm3. There is still some open deliberation that Iridium is the denser component as per hypothetical figurings yet starting at now, Osmium has the most noteworthy measured thickness. </span>
Blood.
<span>Blood is heterogeneous because it has corpuscles (blood cells and platelets) physically suspended in blood plasma. Blood plasma and the corpuscles have different properties and can be separated by methods such as centrifugation. Also, blood is considered a colloid suspension because it has the properties of both a colloid and a suspension. This is because the blood plasma acts as a colloid. More so, if blood was left to settle,then the blood cells would collect at the bottom hence taking the characteristic of a suspension. </span>
<span>Salad dressing.</span>
<span>Depending on the type of salad, it can either be a heterogeneous or homogeneous mixture. If the salad dressing is only of vinegar or any other oil, then it is a homogenous mixture. However, if it involves a mixture of vinegar and other oils, pepper, herbs, and etcetera, then it is a heterogeneous mixture</span>
BF3 acts as a Lewis acid when it accepts the lone pair of electrons that NH3 donates.
Answer:
Chemistry is the science of matter, its properties, structure, changes or reactions and the energy that accompanies these changes.
Answer:- Specific gravity of glucose solution is 1.02.
Solution:- Specific gravity is the ratio of the compound density with water density, means how denser the compound solution is as compared to water.
specific gravity = 
density of glucose is given as 1.02 g per mL and water density is 1.00 g per mL.
Let's plug in the values in the formula:
specific gravity = 
= 1.02
So, the specific gravity of glucose is 1.02. It indicates that glucose is 1.02 times more denser than water.
