Which of these relationships is true of an uncharged atom?

Chemistry
1 answer:
marusya05 [52]3 years ago
7 0

Answer:

The correct option is  C) The number of protons is equal to the number of electrons.

Explanation:

Atoms are made up of particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom and form the nucleus, while electrons surround the nucleus. Electrons have a negative charge. The charge of the protons is positive and finally, the neutrons have no charge.

If the atom has no charge, this means that the total charge of the atomic nucleus, which is positive due to the presence of the protons, is equal to the negative charge of the electrons, so that it cancels out.

So, <u><em>the correct option is  C) The number of protons is equal to the number of electrons.</em></u>

Which describes the boundary where earthquake activity occurs along rift valleys? divergent boundary in the ocean divergent boun
Mila [183]

Answer:

Divergent boundary on land

Explanation:

A rift valley is a lowland region that forms where Earth’s tectonic plates move apart (diverge), or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

Rift valleys are created by tectonic activity and not the process of erosion.

Tectonic plates are huge, rocky slabs of Earth's lithosphere—its crust and upper mantle. Tectonic plates are constantly in motion—shifting against each other in fault zones, falling beneath one another in a process called subduction, crashing against one another at convergent plate boundaries, and tearing apart from each other at divergent plate boundaries.

The most well-known rift valley on Earth is probably the so-called "Great Rift Valley System" which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.

How many molecules of nitrogen monoxide are in a 22.5 gram sample?
poizon [28]
Okay, so you need to start by finding the molar mass (grams in one mole) of nitrogen monoxide (NO).
N=14g
O=16g
So we know that NO has a molar mass of 30 grams, then just divide your given mass of 22.5 grams by the molar mass of 30 grams to find the number of molecules in your sample. The answer should be .75 molecules. Hope this helps!

How do you decide which conversion factor to use?
Juliette [100K]

Answer:

When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot. To convert minutes to hours, the appropriate conversion value is 60 minutes equal 1 hour
