Given the distribution of charges shown in this water molecule, why is it called "polar"?
Answer:
When a covalently bonded molecule has more electrons in one area than another, it is called a polar molecule. The electron cloud model can show an unequal sharing of electrons. ... This shows that electrons are more attracted to the oxygen end of the molecule than the hydrogen end, making the water molecule polar.
Answer:
Water (H2O) is polar due to the reality of the bent form of the molecule. The shape capability most of the terrible fee from the oxygen on facet of the molecule and the great price of the hydrogen atoms is on the one of a kind component of the molecule. This is an occasion of polar covalent chemical bonding.

Which statement is most likely correct?
Rock B may have fossils.
Rock A may have shiny, glassy surface.
Rock A is composed of layers of sediments.
Rock B has a fine grainy texture and small crystals.

Summarize the structure of Earth, including the layers, the mantle, and core, based on the relative position, composition, and density. PLEASE HELP
Answer:
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt.
As a star's size increases, its luminosity ___ as a star's temperature ___, its luminosity increases
1. is the first blank increases or decreases?
2. Is the second blank increases or decreases?
As a star's size increases, its luminosity increases as a star's temperature increases, its luminosity increases.
what is star luminosity ?luminosity is a calculated unit which means the energy produced by stars or galaxy , it is represent in the form of either joules per second or watts.
It generally depends on the size of the star that the lager sized star more energy it give, more luminous.
Secondly, the temperature of the star, if two same sized stars with different temperature, then higher temperature will be more luminous.
It is otherwise determined the actual measure of the absolute magnitude of the power output of the star.
It can be used to understand the stellar classification of various stars.
It can be used to predict the lifecycle of the star and helps astronomers.
luminosity is much more specific than brightness of the star as it is a mathematical calculation.
