Answer:

In both natural and built systems, stability and change are an important focus of study for both scientists and engineers. Stability refers to a system that is unchanging. ... A dynamic equilibrium exists when chemical reactions or physical movements occur at rates that balance out, creating no net change in a system.

A Infiltration

Explanation:

The downward movement of water through pore spaces and other spaces in soil due to gravity is called infiltration.

Infiltration is greatly due to the force of gravity forcing water through pore spaces downward.

Answer:

The pair of arrows which represents the relationship of speeds of the two cars is;

The second option as shown in the attached drawing

Explanation:

The given parameters are;

The reading on the speedometer of one car = 20 m/s

The reading on the speedometer of the other car = 72 km/h = 20 m/s

The blue arrow = 20 m/s

Therefore, given that the speeds of both cars are equal (20 m/s = 72 km/h = 20 m/s),  the pair of arrows that represent the relationship of speeds of the two cars is two equal length blue arrows which is the second option

The attached diagram showing the pair of arrows that represents the relationship of speeds of the two cars is drawn using Microsoft Visio.

Explanation:

There is a limit to different things we encounter around the universe due to a lot of reasons.

To overcome these barriers, some catalysts that are not readily available are needed. This reduces the combination of some atoms in nature.

This and many more reasons limits the combination of chemical substances.

Answer:

Option D. Decomposition reaction

Explanation:

MgBr₂ (s) —> Mg (s) + Br₂ (l)

To know which option is correct. It is important that we have an understanding of what each option means.

1. Synthesis reaction: This is a type of reaction in which two different elements react to produce a new compound different from the two elements that reacted. e.g

A + D —> AD

2. Combustion reaction: This is a reaction which involves a compound and oxygen to produce carbon dioxide (CO₂) and water (H₂O) e.g methane (CH₄) undergoes combustion reaction as follow:

CH₄+ 2O₂ —> CO₂ + 2H₂O

3. Single Replacement reaction: This is a reaction in which one element replaces or displaces another element in a single compound. This is illustrated below:

X + WZ —> XZ + W

We can see that the X replaces W in the reaction.

4. Decomposition reaction: This is a type of reaction in which a compound decompose or breaks into two or more simple compounds or elements e.g

ZX₄ —> Z + 4X

From the above illustrations, we can conclude that the the reaction:

MgBr₂ (s) —> Mg (s) + Br₂ (l)

Is a decomposition reaction because MgBr₂ breakdown into Mg and Br₂

Explanation:

The results shows the reactivity of the halogens and how they displace one another from any solution of their compounds.

The oxidizing power of the halogens decreases from top to down on the group. This explains why the more powerful oxidizing halogens displaces the less powerful one from simple salts.

We see that chlorine is able to displace Bromine and iodine

Bromine is only able to displace Iodine

Iodine cannot displace bromine or chlorine

Answer:

Alkenes contain a double bond that is composed of one sigma and one pi bond between two carbon atoms. The sigma bond has similar properties to those found in alkanes , while the pi bond is more reactive. The carbon atoms in the double bond are sp² hybridized , forming a planar structure.

Answer:

The symbol that represent a salt is CaCl2

Explanation:

The CaCI2 is the calcium chloride that an organic compound now a salt having a chemical formula i.e. CaCI2. Also it is non-color cyrstalline solid at the room temperature also it is highly soluble in the water

Therefore as per the given situation the symbol that represent a salt is CaCI2

This is the answer and the same is not provided in the given options

Explanation:

The amount of rainfall would have the greatest impact on the amount of water available for people in this area. The more the rainfall the more water soaks through layers of porous rocks.Hence, level of water table will remain sufficient for easy pumping of water to the homes.Texas receives plenty of rainfall in a year.In a single year the region can receive up to 48 inches (1,200 mm) of precipitation, and flooding is common near rivers and in low-lying areas. Therefore water table remains intact throughout the year.

Answer:

B. Water quality

Explanation:

Answer:

NH₄NO₃

Explanation:

In salt naming, the cation is named first, then you must put the name of the anion. In the same way when you are writting the formula. Also, the global charge of a salt is always 0.

Thus, we must write each ion and its charge:

Ammonium: NH₄⁺

Nitrate: NO₃⁻

As both ions have the same charge, the formula is:

The cation first and then the anion.

Answer:  1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

2. calcium hydroxide + hydrochloric acid = calcium  chloride + water

3. lead hydroxide + nitric acid =  lead nitrate + water

4. sodium hydroxide + sulfuric acid  =  sodium sulphate + water

5. potassium hydroxide + citric acid = potassium  citrate + water

6. silver hydroxide + hydrochloric acid = silver chloride + water

7.  aluminium hydroxide + phosphoric acid = aluminium phosphate + water

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equations are :

1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

[tex]Mg(OH)_2(aq)+H_2SO_4(aq)\rightarrow MgSO_4(aq)+2H_2O(l)[/tex]

2. calcium hydroxide + hydrochloric acid = calcium  chloride + water

[tex]Ca(OH)_2(aq)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)[/tex]

3. lead hydroxide + nitric acid =  lead nitrate + water

[tex]Pb(OH)_2(aq)+2HNO_3(aq)\rightarrow Pb(NO_3)_2(aq)+2H_2O(aq)[/tex]

4. sodium hydroxide + sulfuric acid  =  sodium sulphate + water

[tex]NaOH(aq)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+H_2O(l)[/tex]

5. potassium hydroxide + citric acid = potassium  citrate + water

[tex]KOH(aq)+C_6H_8O_7(aq)\rightarrow C_6H_7O_7K(aq)+H_2O(l)[/tex]

6. silver hydroxide + hydrochloric acid = silver chloride + water

[tex]AgOH(aq)+HCl(aq)\rightarrow AgCl(s)+H_2O(l)[/tex]

7.  aluminium hydroxide + phosphoric acid = aluminium phosphate + water

[tex]Al(OH)_3(aq)+H_3PO_4(aq)\rightarrow AlPO_4(aq)+3H_2O(l)[/tex]

Answer:

. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

2. calcium hydroxide + hydrochloric acid = calcium  chloride + water

3. lead hydroxide + nitric acid =  lead nitrate + water

4. sodium hydroxide + sulfuric acid  =  sodium sulphate + water

5. potassium hydroxide + citric acid = potassium  citrate + water

6. silver hydroxide + hydrochloric acid = silver chloride + water

7.  aluminium hydroxide + phosphoric acid = aluminium phosphate + water

The first question is option 2

and the second question in option 1

Explanation:

Answer:

i think i like 14 or 8 atom

Explanation:

Answer:

a)6.730×10⁻⁴

b)5×10⁴

c)3.010×10⁻⁶

d)1.3240×10²

e)2.232×10³

The given numbers in scientific notation are [tex]6.730 \times 10^{-4}[/tex], [tex]5.0 \times 10^4[/tex], [tex]1.3240 \times 10^2[/tex],  [tex]2.232 \times 10^3[/tex] and  [tex]2.232 \times 10^3[/tex], respectively.

Scientific notation is a way of expressing very large or very small numbers in a compact and convenient form.

To express a number in scientific notation, we need to write the number in the form: [tex]\rm a\times 10^b[/tex]

a) 0.0006730 can be written in scientific notation as [tex]6.730 \times 10^{-4}[/tex]. The decimal point was moved 4 places to the right, so the exponent is negative 4.

b) 50000.0 can be written in scientific notation as [tex]5.0 \times 10^4[/tex]. The decimal point was moved 4 places to the left, so the exponent is positive 4.

c) 0.000003010 can be written in scientific notation as [tex]3.010 \times 10^{-6}[/tex]. The decimal point was moved 6 places to the right, so the exponent is negative 6.

d) 132.40 can be written in scientific notation as [tex]1.3240 \times 10^2[/tex]. The decimal point was moved 2 places to the left, so the exponent is positive 2.

e) 2232 can be written in scientific notation as [tex]2.232 \times 10^3[/tex]. The decimal point was moved 3 places to the left, so the exponent is positive 3.

Therefore, [tex]6.730 \times 10^{-4}[/tex], [tex]5.0 \times 10^4[/tex], [tex]1.3240 \times 10^2[/tex],  [tex]2.232 \times 10^3[/tex] and  [tex]2.232 \times 10^3[/tex], are the scientific notation for the given numbers.
