What makes a light wave different from all mechanical waves?
Answer:
Light is a transverse wave.
Explanation:
Light waves are not considered mechanical waves because they don't involve the motion of matter. Most of the mathematics and properties of mechanical waves apply to light waves. Light waves are different from mechanical waves, however, because they can travel through a vacuum.

what is the pH of a solution with a pOH of 3.23
Answer:
10.77
Explanation:
The relationship between pH and pOH is
pH + pOH = 14
Plugging in the pOH makes
pH + 3.23 = 14
And solving for pH by subtracting 3.23 on both sides
pH = 10.77

differentiate between condensation polymerization and addition polymerization
Explanation:
The difference between addition polymerization and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers without any by-products whereas in condensation polymerization, the polymers are formed due to the condensation of more than one different monomers resulting in the formation of small molecules such as HCl, water, etc., as by-products.

Work is said to be done when force moves a distance and the direction of motion is in the direction of applied force.
What is work done?Work done is defined as the product of applied force and the distance which the applied force moves.
According to Newton's second law of motion the acceleration of a body is inversely to its mass ut directly proportional to the force and takes place in the direction of the applied force.
Therefore, work is done when force moves a distance and the direction of motion is in the direction of applied force.

Sodium hydroxide is soluble as shown by the following reaction: NaOH(s)-> Na +(aq) + OH-(aq). What is the pOH of a 3.0x10^-3 NaOH solution?
Sodium hydroxide is a soluble strong base. The pOH of a 3.0 × 10⁻³ M-sodium hydroxide solution is 2.5.
What is a base?According to Arrhenius, a base is a species that releases OH⁻ ions in an aqueous medium.
Let's consider the basic reaction of NaOH.
NaOH(s) ⇒ Na⁺(aq) + OH⁻(aq)
NaOH is a strong base. This means that the concentration of OH⁻ will be equal to the initial concentration of NaOH, i.e. 3.0 × 10⁻³ M.
Then, we can calculate the pOH of the NaOH solution using the following expression.
pOH = -log [OH⁻] = -log 3.0 × 10⁻³ = 2.5
Sodium hydroxide is a soluble strong base. The pOH of a 3.0 × 10⁻³ M-sodium hydroxide solution is 2.5.

what volume of N2 is required to convert 5.0L of hydrogen gas to ammonia? assume that all gases are at the same temperature and pressure and that the reaction is complete
Answer:
Approximately [tex]1.7\; {\rm L}[/tex].
Explanation:
Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:
[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].
The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:
[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:
[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].
Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:
[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].

If 25.0 g NO are produced, how many grams of nitrogen gas are used?
A: 5.84 g
B: 11.7 g
C: 23.3 g
D: 33.6 g
Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams
Stoichiometric calculationFrom the equation of the reaction:
N + O ---------> NO
Mole ratio of N to NO is 1:1
Mole of 25.0 g of NO = 25/30.01 = 0.833 moles
Equivalent mole of N = 0.833 moles
Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

What is Levelized Cost of Energy?The Levelized Cost of Energy is a measure of the average net present cost of electricity generation for a generating plant over its lifetime.
The Levelized Cost of Energy of the solar energy product is calculated as follows:
Total cost over 25 years = 995,000, + $175,000 × 25 = $5,370,000
Total energy production over 25 years = 89,500,000 kWh
Levelized Cost of Energy = $5,370,000/89,500,000 kWh
Levelized Cost of Energy = $0.60 per kWh
