Answer:

Arsenic (33As) has 33 known isotopes and at least 10 isomers.

Sand has a lower heat capacity hence it heats up easily and looses heat easily. On the other hand, water has a higher heat capacity and looses heat more slowly hence it remains warm at night.

The transfer of heat refers to the movement of heat from one body to another. We should note that sand has a low specific heat capacity hence it is rapidly heated up in the day and looses heat quickly at night.

On the other hand, water has a high specific heat capacity hence it heat up slowly and also does not loose heat easily even when the surrounding temperature is much colder. As such, there is an extreme temperature difference between day and night in a desert during clear weather and the water in a swimming pool in the desert tends to remain warm even when the outside temperature drops greatly at night.

Answer:

3.0 atm

Explanation:

got it right on edge after guessing 2 times

The resulting pressure of the gas after decreasing the initial volume is 3 atm.

According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of the gas:

P ∝ 1/V

For the given question required equation is:

P₁V₁ = P₂V₂, where

P₁ = initial pressure = 1.5 atm

V₁ = initial volume = 2 L

P₂ = final pressure = ?

V₂ = final volume = 1 L

On putting all these values on the above equation, we get

P₂ = (1.5)(2) / (1) = 3atm

Hence required pressure is 3 atm.

Since iron is more reactive than copper, when steel wopl is placed in a solution of copper (II) sulfate solution into a small beaker, it dissolves and copper metal is produced.

A displacement reaction is one in which a more reactive element displaces another from its compound.

Reactive metals displace less reactive metals from their solutions.

Iron is a more reactive metal than copper and will displace copper from a solution of its salt.

Therefore, when steel wool is placed in a solution of copper (II) sulfate solution into a small beaker, the iron dissolves and copper metal is produced.

Explanation:

The acids that should be stored in plastic containers rather than in glass ones are hydrofluoric acid, phosphoric acid, sulfuric acid, etc.

Acids are those solutions that are sour in taste and have lower pH to 7.

Hydrofluoric acid is highly corrosive, made up of hydrogen and fluorine.

Phosphoric acid is an important oxygen of phosphorus.

The partial pressure is the pressure exerted by a single gas in a volume of the mixture. The partial pressure of dihydrogen is 737.5 mmHg.

According to Dalton's law, the sum of partial pressure of non-reacting gases gives the total pressure of the system.

Given,

Total pressure = 755.0 mmHg

The partial pressure of water = 17.5 mmHg

The partial pressure of dihydrogen = ?

The partial pressure of dihydrogen is calculated as:

[tex]\begin{aligned}\rm p_{total} &= \rm p_{H_{2}O} + p_{H_{2}}\\\\755.0 &=\rm 17.5 + p_{H_{2}}\\\\&= 737.5 \;\rm mmHg\end{aligned}[/tex]

The volume of the 0.15 M LiOH solution required to react with 50 mL of 0.4 M HCOOH to the equivalence point is 133.3 mL

HCOOH + LiOH —> HCOOLi + H₂O

From the balanced equation above,

The mole ratio of the acid, HCOOH (nA) = 1

The mole ratio of the base, LiOH (nB) = 1

MaVa / MbVb = nA / nB

(0.4 × 50) / (0.15 × Vb) = 1

20 / (0.15 × Vb) = 1

Considering the ideal gas law,  there are 279.42 moles of acetylene in the tank.

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

In this case, you know:

Replacing in the ideal gas law:

17.4192 atm× 390 L = n×0.082 [tex]\frac{atmL}{molK}[/tex]× 296.5 K
