What is the difference between a meteor and a meteorite?
Answers
Answer:
meteorites are inside Earth's atmosphere on the ground
meteors are outside Earth's atmosphere
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.

Gerald is fishing. He uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish. Which statement accurately describes the densities of these two items?
1)The bobber and lure are more dense than the water.
2)The bobber and lure are less dense than the water.
3) The bobber is more dense than the water, and the lure is less dense than the water.
4)The bobber is less dense than the water, and the lure is more dense than the water.
Answers
Answer:
4
Explanation:
in order for the bobber to float,it must be less dense, and for the line to sink, it must be more dense.

Calculate the ΔHrxn for the following
2NOCl(g)→N2(g)+O2(g)+Cl2(g)
Given:
12N2(g)+12O2(g)→NO(g)
ΔH = 89.32
NO(g)+12Cl2→NOCl(g)
ΔH = -30.39
Answers
Answer:
2 NO (g) → N2 (g) + O2 (g)
2 NOCl (g) → 2 NO (g) + Cl2 (g)
____________________________
2NOCl (g) ⟶ N2 (g) + O2 (g) + Cl2 (g)
ΔH = [90.3 kJ x 2 x -1] + [-38.6 kJ x -1 x 2] = -103.4 kJ
The ΔH for the reaction is -103.4 kJ
why does gold sink and wood float when they have similar volumes? Include what is happening with the mass size and arrangement of atoms
explain density in your own words
gold sinks and wood floats because____
Answers
Answer:
Gold has a density higher than water so it sinks. Wood has a density lower than water so it floats.
Explanation:
Wood has less packed particles compared to gold. Gold had more packed molecules.
Answer:
Solids are not the only substances that have density. Water and air have density that changes too. Density plays a key role in determining whether objects will sink or float in fluids and gases. Gold sinks in water because gold is denser than water, and pine floats in water because pine is less dense than water.The particles in wood are not so closely packed. There is more space in between the particles and fibres, which gives wood its low density.

This is because the rubbing creates a negative charge that is carried by electrons. When you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.
Ex of experiencing static electricity: when you get shocked on a trampoline due to the nylon material. When bouncing on a trampoline the bouncer can build up static. This is usually when the atmospheric conditions are very dry. Bouncing in these conditions can cause a build up of electrical charge.
