Its just Calcium Flouride because as you can see it is an Ionic bond (Ca is metal and fl is a gas usually)
E mass number of any given atom depends solely on the number of protons and neutrons in its nucleus. The mass number of any atom can be determined by adding the number of protons and neutrons. (Mathematically this is stated as Mass Number = Protons + Neutrons). For instance, a Carbon atom with 6 protons and 6 neutrons will have a mass number of 12AMU. However, a Carbon atom with 6 protons and 8 Neutrons will have a mass number of 14AMU. They are both Carbon atoms, however they each have a different mass number. Atoms of the same element that have different numbers of neutrons, and therefore, different mass numbers, are called isotopes. Isotopic symbols are used to indicate isotopes of the same elements. In the following isotopic symbols the lower number is the atomic number…it is the number of protons. The upper number is the mass number, it represents to sum of the protons and neutrons in the atoms nucleus.
Answer:
the heart would fail to efficiently pump oxygenated blood to the body and lungs
Answer:
force = 11.33 
Explanation:
given data:
sled mass = 17.0 kg
inital velocity (U) = 4.10 m/s
elapsed time (T) 6.15 s
final velocity (V) = 0
final momentum P2 = 0
Initial momentum of sledge is
from newton second law of motion
Kgm/s^2
![F = \frac{69.7-0}{6.15}= 11.33[tex]kg-m/s^{2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B69.7-0%7D%7B6.15%7D%3D%2011.33%5Btex%5Dkg-m%2Fs%5E%7B2%7D)
