The wavelength of the radiation is 4.7 x 10⁻⁹ m
What is the Einstein's Formula for Energy?
The energy
E is given, from Einstein's formula, as:
E=h⋅ν
Where:
h=6.63×10⁻³⁴Js is Planck's constant;
ν is the frequency.
You can relate frequency and wavelength
λ through the speed of light c as:
c=λ⋅ν
So finally you get:
E=hc/λ
It is given in the question
The energy of a photon is 4.23 x 10⁻¹⁷ J.
Wavelength = ?
λ = hc/E
λ = 6.63×10⁻³⁴x 3 x 10⁸ / 4.23 x 10⁻¹⁷
λ = 4.7 x 10⁻⁹ m
Therefore the wavelength of the radiation is 4.7 x 10⁻⁹ m .

You would be most likely to use a slicing machine if you were using the <u>icebox </u>method to produce cookies.
In the icebox method a type of cookie in which the dough is made, rolled into a stick, and refrigerated until the dough hardens. The dough can be removed from the refrigerator, cut into individual pieces, and then baked. The rest of the dough is returned to the refrigerator until needed.
Icebox method, also known as refrigerator cookies, are sliced and baked cookies. The dough is formed into logs, chilled in the refrigerator (also called an icebox), sliced , and then baked.

Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)
Answer : The correct option for blank 1 is, Shifts left.
The correct option for blank 2 is, Reverse.
Explanation :
According to the Le Chatelier's Principle, when the addition of the reactant in reaction system then the equilibrium will shift to the right (forward) direction of the reaction.
Or, if we remove the reactants from the reaction system then the equilibrium will be shifted to the left (backward) direction of the reaction. And simultaneously, there will be increase in the reverse reaction for the attainment of the equilibrium.
