in which type of condition is a conditions is a landslide most likely to occur

Answer:

Pressure will increase by the direct ratio of the volume change. Therefore, since volume changes from 145 to 80, pressure will go up by the ratio change 145÷80 times the original pressure 125 kPa. Sure, you can use the more complicated gas law equation PV = nRT but we are only varying volume so the question boils down to the change in one simple variable.

Putting them together we have: 145÷80 x 125 = 226.5625 or just 226 kPa since the accuracy of the figures and the equation are not great.

Answer:

Explanation:

To compare the average speed, we would need some parameters which you clearly didn't state in your question. However, permit me to manufacture some from thin air.

The formula for average speed is given as

Speed = distance / time

From the question, we have the time, but not the distance moved by the horse. Now, assuming the horse moves a distance of 60 meters, then we can say,

Speed = 60 / 60

Where the difference between the two time, t = 120 - 60 = 180 - 120 = 60

So, from my hypothesized example, the average speed of the horse is 1 m/s

Answer:

The interior of the Earth, like that of the other terrestrial planets, is chemically divided into layers. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.

Periodic table has been divided into three, one is metal, second is non metal and third metalloid. Therefore,  hydrogen is considered as non metal.

Metals are those elements which is hard, conduct electricity, ductile, lustrous and malleable.

Lets take property

1.Since metals have free electrons that's why they can conduct electricity

2. Since atoms in metals are very closely packed in a definite crystal so Aluminium is solid. It is not brittle that is it can not be broken down easily

3. It does not react with water.

4.It is denser than water hence it sink in water.

Since hydrogen has only 1 electron in its outermost shell, to complete its duet and gain stability, hydrogen has to gain 1 electron just like halogen. So, on this basis hydrogen is considered as non metal.

Therefore,  hydrogen is considered as non metal.

Answer:If we dissolve NaF in water, we get the following equilibrium:

text{F}^-(aq)+text{H}_2text{O}(l) rightleftarrows text{HF}(aq)+text{OH}^-(aq)

The pH of the resulting solution can be determined if the  K_b of the fluoride ion is known.

20.0 g of sodium fluoride is dissolve in enough water to make 500.0 mL of solution. Calculate the pH of the solution. The  K_b of the fluoride ion is 1.4 × 10 −11 .

Step 1: List the known values and plan the problem.

Known

mass NaF = 20.0 g

molar mass NaF = 41.99 g/mol

volume solution = 0.500 L

K_b of F – = 1.4 × 10 −11

Unknown

pH of solution = ?

The molarity of the F − solution can be calculated from the mass, molar mass, and solution volume. Since NaF completely dissociates, the molarity of the NaF is equal to the molarity of the F − ion. An ICE Table (below) can be used to calculate the concentration of OH − produced and then the pH of the solution.

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

these metals are stored in kerosene because kerosene contains no water and protects these metals from being exposed to any moisture in the air that would cause these metals to react, potentially violently.

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

Explanation:

Answer:

The particles move very fast and collide into one another, causing them to diffuse, or spread out, until they are evenly distributed throughout the volume of the container. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed.

Explanation:

Answer: The ratio of the initial volume to final volume for the given gas is 27 to 127 L at constant pressure.

Explanation:

Given: [tex]T_{1} = 27^{o}C[/tex]

[tex]T_{2} = 127^{o}C[/tex]

According to Charle's law, for an ideal gas pressure is directly proportional to the temperature at constant pressure.

So, formula used to calculate the ratio of the initial volume to final volume is as follows.

[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{V_{1}}{V_{2}} = \frac{T_{1}}{T_{2}}\\\frac{V_{1}}{V_{2}} = \frac{27}{127}[/tex]

Hence, we can conclude that the ratio of the initial volume to final volume for the given gas is 27 to 127 L at constant pressure.

Answer:

The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.

Explanation:

The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.

Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.

Air typically moves from areas of lower pressure to areas of higher pressure.

Answer:

CH2

Explanation:

The empirical formula is the simplest formula of a chemical compound. It shows the ratio in which constituent atoms are combined in the compound.

To obtain the empirical formula, we divide the given mass of each element by the relative atomic mass of that element.

C- 36.0 g/12.0 g         H- 6.0g/1.0g

C- 3                             H-6

Divide through by the lowest ratio;

C-3/3                              H- 6/3

C-1                                  H-2

Hence the empirical formula of the compound is

Q = 5036.9 calories

Explanation:

Given that,

Mass, m = 167.9 g

The temperature raises from 25°C to 55°C.

The specific heat of water,c = 4.184 J/g °C

We need to find the heat added to water. We know that,

[tex]Q=mc\Delta T\\\\=167.9 \times 4.184\times (55-25)\\\\=21074.8\ J[/tex]

or

Q = 5036.9 calories

So, 5036.9 calories of heat is added.
