So NH4Cl has ionic bond between NH4+ and Cl-, hydrogen bond (can be considered covalent bond too and N and H are both non metals and covalent bonds occur between non metals) between N and H in NH4 and covalent bond between NH4 and another NH4.
Answer:
The answer to your question is length is an extensive property
Explanation:
There are two physical properties: extensive and intensive properties.
An extensive property is a property that depends on the amount of matter.
An intensive property is a property that does not depend on the amount of matter.
Answer:
Explanation:
There are 3 major subatomic particles:
<em>Proton</em>
<em>Neutron </em>
<em>Electron </em>
- Surrounding the nucleus in orbitals
Two (protons and neutrons) of the three particles are found in the nucleus of an atom. <u>Electrons</u> are not, they are surrounding the nucleus.
Answer:
proton 5+
electron 5-
neutron 0, neutral
Explanation:
Boron is the fifth element on the periodic table, meaning it's atomic# is 5. that is the # of protons. Protons have a positive chargé. The # of electrons in a neutrally charged atom is the same as the # of protons, because they're negatively charged. so if there are 5 protons, there are 5 electrons +5 + -5 = 0 chargé. The third subatomic particle is a neutron. It has a charge of 0, neutral, thus its name. You know there are 6 neutrons in a Boron atom because the atomic mass is 11. electrons have basically no weight, so 11 - 5 protons = 6 neutrons.
Before the bullet is fired the momentum is Zero because nothing is moving but once the bullet is shot the momentum increases because of the movement of the bullet moving forward.
