<u>Answer:</u> For the given reaction, the value of 
is greater than 1
<u>Explanation:</u>
For the given chemical equation:
The expression of for above equation follows:
![K_c=\frac{[Ca^{2+}]\times [CO_3^{2-}]}{[CaCO_3}]\\\\K_c=[Ca^{2+}]\times [CO_3^{2-}]](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCa%5E%7B2%2B%7D%5D%5Ctimes%20%5BCO_3%5E%7B2-%7D%5D%7D%7B%5BCaCO_3%7D%5D%5C%5C%5C%5CK_c%3D%5BCa%5E%7B2%2B%7D%5D%5Ctimes%20%5BCO_3%5E%7B2-%7D%5D)
The concentration of pure solids and pure liquids are taken as 1 in equilibrium constant expression
As, the denominator is missing and the numerator is the only part left in the expression. So, the value of will be greater than 1.
Hence, for the given reaction, the value of is greater than 1

Answer:
1080 photons
Explanation:
ΔE = hc/λ => Energy per photon
h = 6.63 x 10⁻³⁴ j·s
c = 3 x 10⁸ m/s
λ= 535 nm = 5.35 x 10⁻⁷ m
ΔE/photon = (6.63 x 10⁻³⁴ j·s)(c = 3 x 10⁸ m/s)/(5.35 x 10⁻⁷ m) = 3.71 x 10⁻¹⁹ j/photon
For #photons in 4.00 x 10⁻⁷ j = (4.00 x 10⁻⁷ j) / (3.71 x 10⁻¹⁹ j/photon) = 1076 photons ≅ 1080 photons (3 sig. figs.)
Answer:
The pH of a solution with a (H+] = 0.80 M is 
Explanation:
As we know
pH = -[log H+]
Substituting the value of H+ ion concentration in the above equation, we get -
pH = -log [0.80]
pH ![= -[-0.096] = 0.096 = 9.6 e^{-2}](https://tex.z-dn.net/?f=%3D%20-%5B-0.096%5D%20%3D%200.096%20%20%3D%209.6%20e%5E%7B-2%7D)
Answer:
Smaller
Explanation:
Though, your question is not too clear but base on my understanding, I have the following explanation;
The angle in the bromine-oxygen bonds will be smaller than the ideal angle, say for example, if the ideal angle is 120°, the actual angle of bromine-oxygen bonds will have lesser value because of the absence of lone pairs of electrons from the central atom in the ion. This will tend to squeeze the two single bond that exist before causing lesser angle.
