Answer:
A reaction will occur when CaCl2 is combined with F2.
Explanation:
Let us know the terms at first.
Ca- Calcium
Cl2- Chloride, therefore CaCl2 is Ca+ Cl2 and that is calcium chloride.
Now, F2 is fluorine which is a yellow compressed gas.
When CaCl2 combines with F2, it gives out products like CaF2 or calcium fluoride, which is a white crystalline solid in powder form, and Cl or chlorine, which appears as a greenish-yellow compressed liquid gas with a pungent smell.
Here is the equation,
CaCl2+ F2= CaF2+ Cl.
1. mol = 77.56/100 = 0.7756 mol
2. mol = 2.55 × 10^24/6.02 × 10^23 = 4.236 mol mass = 4.236 × 74.5 = 315.582 g
3. mass = 0.0931 × 208.3 = 19.393 g
4. mol = 1.55 × 10^22/6.02 × 10^23 = 0.0257 mol
5. molecules = 0.664 × 6.02 × 10^23 = 3.997 × 10^23 molecules
6. mol = 86/242 = 0.355 mol
7. mol = 7.88 × 10^23/6.02 × 10^23 = 1.309 mol mass = 1.309 × 44 = 57.596 g
8. mass = 7.56 × 62 = 468.72 g
9. mol = 7.56/84 = 0.09 mol
10. mol = 8.55 × 10^21/6.02 × 10^23 = 0.014 mol mass = 0.014 × 58.5 = 0.819 g

<span>A cell membrane protects the structures within the cell. They are semipermeable which means that only certain objects are able to pass through them. They also give shape to the cell and support its structure. </span>
Answer:
P1 =4 atm
T1= 20°C
P2=1 atm
T2=?
According to Gay-Lussac's Law or Third Gas Law,
P1T2=P2T1
4×T2=1×20
T2= 20/4
T2= 5°C
Answer At 5°C temperature does a gas at 1.00 atm !
"The boron-nitrogen interaction in the studied molecules shows some similarities with the N→B bond in the H3N-BH3 molecule, formally understood as covalent-dative. ... The results show that all the studied BN bonds are triple, since three two-center orbitals have been obtained."
"Formation of a dative bond or coordinate bond between ammonia and boron trifluoride. When the nitrogen donates a pair of electrons to share with the boron, the boron gains an octet. ... In addition, a pair of non-bonding electrons becomes bonding; they are delocalized over two atoms and become lower in energy."
