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.

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.

The first question is option 2

and the second question in option 1

Explanation:

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.

Answer:

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:  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

Answer:

B. They are highly reactive.

Explanation:

Answer:

B: They are highly reactive

Explanation:

Sodium(Na) and potassium(K) are in the same family/group which is the Alkali Metal group.  These groups have their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water. This is because enough heat is given off during the exothermic reaction to ignite the H2(g). Therefore, they are similar because of their reactivity.

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.
