Answer:

When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Explanation:

When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Trigonal planars have a 180 degree bond angle but do bent trigonal planars also have a 180 degree bond angle? Thank you ^^
Yanka [14]

Answer:


The ideal bond angle is 120°, but the real bond angle of bent molecules is usually a few degrees less.


Explanation:


The bonds of a trigonal planar AX₃ molecule point toward the corners of an equilateral triangle.


They trisect a circle into three angles of 120° each.


An example is BF₃ (Figure 1). It is perfectly symmetrical, so the F-B-F bond angles are exactly 120°.


===============


Now, consider ozone (Figure 2).


The two O-O bonds are equivalent because of resonance.


There are two bonding groups and a lone pair, for a total of three electron groups.


The electron geometry is trigonal planar, and the molecular shape is bent.


However, the lone pair occupies more space than the bonding electrons.


It repels the bolding electrons, so the O-O-O bond angle is 116°, slightly less than the ideal angle of 120°.

how do we know that all the continents were all together at one point in time. writing prompt and it has to be at least 7 senten
kari74 [83]

Answer:

We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.

HELP Consider this equation...
Mashcka [7]

Answer:

it is not correct I have an answer for ''why''

Explanation:

You need to balance it

s= 2

0=2

S+30•2 --------> SO•3

2 2 2 2

S +3O•2-------->SO•2......MULTIPLY

2 4 2 4......LCM IS 4

2 1 2 1....DIVIDE BY 4

SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.

2S+3O•2 -----> 2SO•3

now you can check the both sides its balances the correct answer is this
