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

Answer:

AAAAAAAAAAAAA  i just finished the exam

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.

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

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.

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:

5.14mole

Explanation:

Given parameters:

Mass of sodium bicarbonate  = 431.56g

Unknown:

Number of moles  = ?

Solution:

To find the number of moles, we use the expression below:

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

 Molar mass = 84.01g/mol

 Number of moles  = [tex]\frac{431.56}{84.01}[/tex]   = 5.14mole

Answer:

B. Mass in motion. Is the definition of momentum

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.

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.

I think its the third one im not sure tho

Explanation:

Answer:

63.6%

Explanation:

The given compound is:

     N₂O;

The problem here is to find the percent composition of nitrogen in the compound.

First find the molar mass of the compound:

 Molar mass of N₂O = 2(14) + 16  = 44g/mol

So;

 Percentage composition of Nitrogen  = [tex]\frac{2 x 14}{44}[/tex]  x 100  = 63.6%
