Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
Answer:
A. Biodiversity can increase the rate of extinction
Explanation:
That statement is false because variety is better for a better ecosystem. With variety more can survive in certain situations that others cant.
Answer:
Explanation:
An ionic compound is a compound in which electrovalent bonds joins the atoms together. Here, electrons move from a less electronegative atom to a more electronegative one. The formation of ionic bonds involves the transfer of elecrons.
The transfer of electrons makes the atoms charged i.e ionized. These oppositely charge ions establishes an electrostatic force of attraction to form the ionic compounds.
How is electrical neutrality maintained in an ionic compound?
Electrical neutrality is maintained in an ionic compound because the compound is made up of ions in which the net charge is zero. There is a transfer of electrons which is completely recieved by the more electronegative atom.
Answer:Sugars are actively transported from source cells into the sieve-tube companion cells, which are associated with the sieve-tube elements in the vascular bundles. ... The co transport of a proton with sucrose allows movement of sucrose against its concentration gradient into the companion cells.
