Energy of photon is equal to the product of Planck's constant and frequency.

The mathematical expression is given as :

E = h\nu

where,

E = energy of photon

h = Planck's constant i.e. 6.626 \times 10^{-34} Js

\nu = frequency

Put the given values of frequency and Planck's constant in above formula, we get

E =6.626 \times 10^{-34} Js\times 7.05 \times 10^{14} Hz

= 46.7133\times 10^{-20} Js Hz

Since, Hz is equal to second^{-1}

Thus, energy of photon =  46.7133 \times 10^{-20} J or 4.67133 \times 10^{-19} J

Elena L [17]

Answer:

Engineering is all about solving problems using math, science, and technical knowledge. And engineers have solved a lot of problems in the world by designing and building various technologies. We have everything from machines that can breathe for you in hospitals to suspension bridges to computers we use every day. All of these things were once designed by engineers using the engineering design process.

A 10.0-milliliter sample of NaOH(aq) is neutralized by 40.0 milliliters of 0.50 M HCl. What is the molarity of the NaOH(aq)?
Ludmilka [50]
\frac{10 mL}{1000 mL}  = 0.01 L

\frac{40mL}{1000mL} =0.04L

M _{1} V_{1}=M_{2}V_{2}

M_{1}(0.01)=(0.50)(0.04)

M_{1}(0.01)=0.02

M_{1}= \frac{0.02}{0.01}

M_{1}=2

Consider a 175.7 g sample of the compound manganese(IV) perchlorate.
kramer

Answer:

6.21 moles O

Explanation:

To find the moles of oxygen, you need to (1) convert grams Mn(ClO₄)₄ to moles Mn(ClO₄)₄ (via molar mass) and then (2) convert moles Mn(ClO₄)₄ to moles O (via mole-to-mole ratio from formula subscripts). It is important to arrange the conversions/ratios in a way that allows for the cancellation of units.

Molar Mass (Mn(ClO₄)₄): 452.74 g/mol

1 Mn(ClO₄)₄ = 1 Mn and 4 Cl and 16 O

175.7 g Mn(ClO₄)₄           1 mole                   16 moles O
---------------------------  x  -------------------  x  ---------------------------  =  6.21 moles O
                                       452.74 g            1 mole Mn(ClO₄)₄
