Answer:

Solids dont flow because there is a strong attraction between the atoms, keeping them bonded together tightly.

Explanation:

They will continue being solid until temperature is increased at the melting point.

Work is said to be done when force moves a distance and the direction of motion is in the direction of applied force.

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.

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

Carbon monoxide with pressure pCO = 0.01 at 800°C is use to reduce the nickel oxide to metallic nickel.

The chemical symbol is CO.

Nickel can be extracted from it's ore through extractive metallurgy. This entails the process of conventional roasting and reduction processes of nickel ore which will produce nickel metal which is greater than 75% purity. In stainless steel applications, 75% pure nickel can be used without been purified furthe purification which depend the components impurities of impurities present in it. Carbon monoxide is use as the reducing agent as it reduce it from nickel oxide to nickel metal.

Sodium hydroxide is a soluble strong base. The pOH of a 3.0 × 10⁻³ M-sodium hydroxide solution is 2.5.

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.

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.

The cell notation of the redox reaction between Cu and ClO₃⁻ is:

A voltaic cell or electrochemical cell is a device which produces electricity from chemical reactions occuring within the cell.

The reactions occuring in a voltaic cell are redox reactions.

Oxidation occurs at the anode while reduction occurs at the cathode.

In the given reaction between Cu and ClO₃⁻ as shown below:

Cu is oxidized as follows: 3 Cu (s) → 3 Cu²⁺
ClO₃⁻ is reduced as follows: ClO₃⁻ (aq) → Cl⁻ (aq)

The voltaic cell notation is as follows where Pt is used as an inert electrode in contact with the ClO₃⁻ and Cl⁻:

Therefore, the cell notation of the redox reaction between Cu and ClO₃⁻ shows that Cu is oxidized while ClO₃⁻ is reduced.

Explanation:

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

From 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

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].

The Levelized Cost of Energy of the solar plant is $0.60 per kWh.

Solar energy and wind energy can both easily be integrated into existing power grid systems.

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

The Levelized cost of energy (LCOE) is the minimum amount of power that can be produced per dollar over the lifetime of a power-generating project.

For solar energy and wind energy, power from both energy sources can easily be integrated into existing power grid systems.
