First we calculate the mass of carbon,
hydrogen and oxygen.
Mass of Carbon;<span>
Molar mass of CO</span>₂ is 44.009g/mol and molar mass of C = 12.011 g/mol
<span>Mass of Carbon in 14.08g CO2</span>₂ = 12.011/44.009 x 14.08 = 3.84
<span>
Mass Hydrogen;
Molar mass H</span>₂O is 18.0015g/mol and molar mass of H is 1.008and H₂ = 2.016
<span>Mass Hydrogen in 4.32g of H</span>₂O = 2.016/18.0015 x 4.32 = 0.48
<span>
<span>Mass of Oxygen
= total mas of tartaric acid – (mass of carbon + mass of hydrogen) = 12.01 -
(3.84+0.48) = 7.69</span>
Now divide carbon, hydrogen and oxygen through
their respective atomic masses: </span>
<span>C = 3.84/12.011 = 0.32
<span>H = 0.48/1.008 = 0.48
<span>O = 7.69/15.999 = 0.48
Now divide by smallest: </span>
C = 0.32/0.32 = 1 </span>
H = 0.48/0.32 = 1.5
O = 0.48/0.32 = 1.5
multiply by 2 to get whole integers: </span>
C = 1 x 2 = 2
H= 1.5 x 2 = 3
<span>O= 1.5 x 2 = 3
<span>Thus, the Empirical formula of tartaric acid =
C</span></span>₂H₃O₃
Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°
Explanation: Formula used to calculate the hybridization:
![{\text{Number of electron pairs}} =\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom i.e. carbon = 4
N = number of monovalent atoms bonded to central atom = 2
C = charge of cation = 0
A = charge of anion = 0
For 
![{\text{Number of electron pairs}} =\frac{1}{2}[4+2-0+0]=3](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5B4%2B2-0%2B0%5D%3D3)
The number of electron pairs are 3 which means that the hybridization will be 
and the electronic geometry of the given molecule will be trigonal planar.
The bond angle in this electronic geometry is 120°
The structure of phosgene is attached below.
Answer:
the reaction is exothermic
Explanation:
heat will be produced from the reaction
Answer:
Change in velocity (\Delta v) is acceleration (a) times time (t)
Acceleration a=1.2\ m/s^{2}
Time t=10\ s
So \Delta v=at=1.2\ m/s^{2}*10\ s=12\ m/s
The initial velocity is then 16\ m/s-12\ m/s=4\ m/s
Easy Answer: 4m/s
