I think the answer would be 1.58 g.
Answer:
Half of Earth’s oceans are not owned by any particular country.
Explanation:
Reducing oil pollution requires an international effort because ocean waters do not have boundaries and there are certain portion of the ocean that are not owned by any nation.
- Oil pollution is a serious environmental issue.
- Oil spills can be carried by ocean currents from one place to another.
- They affect the aquatic ecosystem within a locality thereby reducing the biodiversity of life.
International collaborations are sought to combat any issue of oil spillage due to global undertone to it.
H20 is water?????booom
Yes answer
In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
Answer:
C
Explanation:
okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.
- particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)
- liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a <em>really tight</em> crowd I guess
- gas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.
- since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that is the mixture must get to a point where all regions have the same concentration of the dye.
you can refer to your coursebooks :)
correct where wrong please:)
