Explanation:

Specific heat =   Q/(m *Tchange)

re-arrange to

Tchange =  Heat/(m *spec heat)

Answer:

Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.

Following are the harmful effects caused by the oxides of nitrogen

Nitrogen oxides causes irritation in mucous membrane.

Large concentrations of Nitrogen oxide causes lungs problems in humans

It causes injuries to vegetation by damaging leaves.

Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.

NO: sharp, sweet-smelling, colourless gas. Melting point: -163.6°C. Boiling point: -151.8°C. Relative Density: 1.04 (air = 1) NO2: reddish-brown gas with irritating odour

Taking into account the definition of molarity, the molarity of the solution formed by dissolving 3.00 moles of NaCl in enough water to yield 4.00 L of solution is 0.75 [tex]\frac{moles}{liter}[/tex].

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, you know:

Replacing in the definition of molarity:

[tex]Molarity=\frac{3 moles}{4 L}[/tex]

Solving:

molarity= 0.75 [tex]\frac{moles}{liter}[/tex]

Finally, the molarity of the solution formed by dissolving 3.00 moles of NaCl in enough water to yield 4.00 L of solution is 0.75 [tex]\frac{moles}{liter}[/tex].

Answer:

Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.

Explanation:

Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electric power for use in an external circuit.

Lightning is an electric current. To make this electric current, a cloud is needed.

When the ground is hot, it heats the air above it. This warm air rises. As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger. In the tops of the clouds, the temperature is below freezing and the water vapour turns into ice.

Now, the cloud becomes a thundercloud. Lots of small bits of ice bump into each other as they move around. All these collisions cause a build-up of electrical charge.

Eventually, the whole cloud fills up with electrical charges. Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.

When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger.

Hence, the positive and negative charges grow large enough, that a giant spark - lightning - occurs between the two charges within the cloud.

A covalent bond is formed by the sharing of electrons between 2 atoms.

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Sharing of electrons forms covalent bonds between the atoms.

These bonds are mainly formed between two similar atoms of electronegativity.

Where ionic bonds are formed by sharing electrons where there is an electronegativity difference between metals and non-metals. Ex. NaCl

The principal law governing pollution of the nation’s surface waters is the Federal Water

Pollution Control Act, or Clean Water Act. Originally enacted in 1948, it was totally revised by

amendments in 1972 that gave the act its current dimensions. The 1972 legislation spelled out

ambitious programs for water quality improvement that have since been expanded and are still

being implemented by industries and municipalities.

This report presents a summary of the law, describing the statute without discussing its

implementation. Other CRS reports discuss implementation, including CRS Report R42883,

Water Quality Issues in the 113th Congress: An Overview, and numerous products cited in that

report.

The Clean Water Act consists of two major parts, one being the provisions which authorize

federal financial assistance for municipal sewage treatment plant construction. The other is the

regulatory requirements that apply to industrial and municipal dischargers. The act has been

termed a technology-forcing statute because of the rigorous demands placed on those who are

regulated by it to achieve higher and higher levels of pollution abatement under deadlines

specified in the law. Early on, emphasis was on controlling discharges of conventional pollutants

(e.g., suspended solids or bacteria that are biodegradable and occur naturally in the aquatic

environment), while control of toxic pollutant discharges has been a key focus of water quality

programs more recently.

Prior to 1987, programs were primarily directed at point source pollution, that is, wastes

discharged by industrial and municipal facilities from discrete sources such as pipes and outfalls.

Amendments to the law in that year authorized measures to address nonpoint source pollution

(runoff from farm lands, forests, construction sites, and urban areas), which is estimated to

represent more than 50% of the nation’s remaining water pollution problems. The act also

prohibits discharge of oil and hazardous substances into U.S. waters.

Under this act, federal jurisdiction is broad, particularly regarding establishment of national

standards or effluent limitations. Certain responsibilities are delegated to the states, and the act

embodies a philosophy of federal-state partnership in which the federal government sets the

agenda and standards for pollution abatement, while states carry out day-to-day activities of

implementation and enforcement.

To achieve its objectives, the act is based on the concept that all discharges into the nation’s

waters are unlawful, unless specifically authorized by a permit, which is the act’s principal

enforcement tool. The law has civil, criminal, and administrative enforcement provisions and also

permits citizen suit enforcement.

Financial assistance for constructing municipal sewage treatment plants and certain other types of

water quality improvements projects is authorized under Title VI. It authorizes grants to capitalize

State Water Pollution Control Revolving Funds, or loan programs. States contribute matching

funds, and under the revolving loan fund concept, monies used for wastewater treatment

construction are repaid to states, to be available for future construction in other communities.

For example, if you put a heat lamp closer to a rock the rock would get warmer, if you put it further away it would receive less heat therefore making less warmer.

Answer:

-65 kJ

Explanation:

To use Hess's Law, you need to combine the equations in a way that results in the desired equation. To add reactants/products, just add the equations and their subsequent heat of reactions. Subtracting reactants/products involves flipping the signs of enthalpies, duplicating reactants/products involves multiplying the coefficients and enthalpies by a desired number.

    A + 2B -->   C + D

+            B --> 2C + D
------------------------------------

    A + 3B --> 3C + 3D

In this case, you only need to add the equations together to get the desired equation. Because you just add the equations, combine each equations' heat of reaction.

(-20 kJ) + (-45 kJ) = -65 kJ

The overall heat of reaction of the desired reaction is -65 kJ.

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.

Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.

Given that quantity of salt solution = 2.50 L

We know that, 1 L = 1.06 qt

Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:

2.50L = 2.50L × 1.06qt/L = 2.65qt
