Explanation:

Mass of water vapor = 193 g

Given

435 kJ of heat are released

Required

mass of water vapor

Solution

The heat to change the phase can be formulated :

Q = mLf (melting/freezing)

Q = mLv (vaporization/condensation)

Lv for water = 2256 kJ/kg or 2256 J/g or 40.7 kJ/mol

So the mass of water vapor :

[tex]\tt m=\dfrac{Q}{Lv}\\\\m=\dfrac{435000~J}{2256~J/g}\\\\m=192.8\approx 193~g[/tex]

The Middle Years

Explanation:

Depending on the size of the star, the period of which thermal energy is created through the process of nuclear fusion can vary. However, for the life cycle of an average star, this can be roughly a few billion to 10 or even 15 billion years

Answer:

The force factors are equal to the first numbers of the products of the masses in scientific notation.

Explanation:

Ex. 1.0 x 10^5 kg^2 then the force factor would be 1.

ex. 3.0 x 10^12 kg^2 then the force factor would be 3.

To solve this we must be knowing each and every concept related to  scientific notation and its calculations. Therefore, in scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.

Mathematics is a way of representing numbers using a decimal number ranging from one to 10, but not 10 multiplied by a factor of 10. The most common type of mathematical notation is All numbers in scientific notation are expressed in the generic form N 10m.

In scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.

Example1 1.0 x 10⁵ kg² , force factor is 1.

Example2 3.0 x 10¹² kg² ,force factor is 3.

Therefore, in scientific notation, the force factors seem to be equivalent to the first digits of the masses' products.

Explanation:

Iron becomes liquid when we heat it to a temperature of 1535° C this is it's melting point. If we further heat the liquid to 3,000° C it boils; iron is a gas above this temperature.

Answer:

Troposphere, stratosphere, mesosphere, and thermosphere.

Explanation:

Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.

Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).

Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.

Answer:

The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.

Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

Answer:

The value of the equilibrium constant (K) remains the same.

Explanation:

A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.

At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.

Answer:

10%-saline solution = 60mL

15%-saline solution = 40mL

Explanation:

Let

10%-saline solution = x

15%-saline solution = y

x + y = 100

0.1x + 0.15y = 100*0.12

x + y = 100 (1)

0.1x + 0.15y = 12 (2)

from (1)

x = 100 - y

Substitute x = 100 - y into

0.1x + 0.15y = 12

0.1(100 - y) + 0.15y = 12

10 - 0.1y + 0.15y = 12

- 0.1y + 0.15y = 12 - 10

0.05y = 2

y = 2 / 0.05

y = 40mL

Substitute y = 40 into

x + y = 100

x + 40 = 100

x = 100 - 40

x = 60mL

10%-saline solution = 60mL

15%-saline solution = 40mL

AnsThe option C is correct

The rate of a reaction would be one-fourth.

Given

Rate law-r₁ = k [NO]²[H2]

Required

The rate of a reaction

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

Can be formulated:  

Reaction: aA ---> bB  

[tex]\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}[/tex]

or  

[tex]\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}[/tex]

The concentration of NO were halved, so the rate :

[tex]\tt r_2=k[\dfrac{1}{2}No]^2[H_2]\\\\r_2=\dfrac{1}{4}k.[No]^2[H_2]\\\\r_2=\dfrac{1}{4}r_1[/tex]

Answer:

C. The rate would be one-fourth.

Another option would be:

The rate would be four times larger

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

Answer:

BF3

Explanation:

For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

I hope this helps.
