Answer:
56°
Explanation:
First calculate ![a:](https://tex.z-dn.net/?f=a%3A)
![a=2 R \sqrt{2}=2(0.1246) \sqrt{2}=0.352 \mathrm{nm}](https://tex.z-dn.net/?f=a%3D2%20R%20%5Csqrt%7B2%7D%3D2%280.1246%29%20%5Csqrt%7B2%7D%3D0.352%20%5Cmathrm%7Bnm%7D)
The interplanar spacing can be calculated from:
![d_{111}=\frac{a}{\sqrt{1^{2}+1^{2}+1^{2}}}=\frac{0.352}{\sqrt{3}}=0.203 \mathrm{nm}](https://tex.z-dn.net/?f=d_%7B111%7D%3D%5Cfrac%7Ba%7D%7B%5Csqrt%7B1%5E%7B2%7D%2B1%5E%7B2%7D%2B1%5E%7B2%7D%7D%7D%3D%5Cfrac%7B0.352%7D%7B%5Csqrt%7B3%7D%7D%3D0.203%20%5Cmathrm%7Bnm%7D)
The diffraction angle is determined from:
![\sin \theta=\frac{n \lambda}{2 d_{111}}=\frac{1(0.1927)}{2(0.2035)}=0.476](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%3D%5Cfrac%7Bn%20%5Clambda%7D%7B2%20d_%7B111%7D%7D%3D%5Cfrac%7B1%280.1927%29%7D%7B2%280.2035%29%7D%3D0.476)
Solve for ![\theta](https://tex.z-dn.net/?f=%5Ctheta)
![\theta=\sin ^{-1}(0.476)=28^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Csin%20%5E%7B-1%7D%280.476%29%3D28%5E%7B%5Ccirc%7D)
The diffraction angle is:
![2 \theta=2\left(28^{\circ}\right)=56^{\circ}](https://tex.z-dn.net/?f=2%20%5Ctheta%3D2%5Cleft%2828%5E%7B%5Ccirc%7D%5Cright%29%3D56%5E%7B%5Ccirc%7D)
Answer: ![Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu](https://tex.z-dn.net/?f=Zn%28s%29%2BCuSO_4%28aq%29%5Crightarrow%20ZnSO_4%2BCu)
Explanation:-
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
As zinc is more reactive than copper, it could easily displace copper from its aqueous solution and thus leads to formation of zinc (II) sulfate and pure copper.
The chemical reaction can be represented as :
![Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu](https://tex.z-dn.net/?f=Zn%28s%29%2BCuSO_4%28aq%29%5Crightarrow%20ZnSO_4%2BCu)
The phases are represented as (s) for solid sate, (l) for liquid state, (g) for gaseous state and (aq) for aqueous state.
Answer:
I have no clue what the question is
Q = 1.161 J/kg of heat is required to melt 99.9 g of solid acetic acid (HCH,CO2). Q = mL(Latent heat is the energy emitted or absorbed by a body while changing it state ). (Latent heat is the energy released or absorbed by a body while changing it state ).
<h3>How to fix?</h3>
Apply the equation Q = mL where:
Energy is Q. (J)
m = Mass (g)
L = Acetic acid's latent heat of fusion 192(J/g) = J/g
Q is equal to 0.099 kg times 11.73 kj/mol.
Q = 1.161J/kg.
<h3>What is latent heat, and what varieties are there?</h3>
Latent heat is the amount of energy that a substance experiencing a change in state, such as ice turning into water or water turning into steam, can absorb or release while maintaining a constant temperature and pressure. Types: The material exists in three states: solid, liquid, and gaseous.
<h3>What does "sensible heat" mean?</h3>
Heat that can actually be felt is considered to be sensible heat. Instead of the phase shifting, energy is what causes the temperature to vary as it moves from one system to another. For instance, it warms the water instead of melting the ice.
