How might the population of owls be affected if the population of grasshoppers were to suddenly decrease

when a beaker of water is heated with a yellow burner flame ;

Yellow burner flames are caused by incomplete combustion of gas and the incomplete combustion results to the presence of soot in the flame. yellow flame produces less heat energy than blue burner flames.

While when a blue burner flame is used to heat a water contained in a beaker the water gets heat up faster and the beaker remains clean ( void of soot deposits ).

Hence we can conclude that when a beaker of water is heated with a yellow burner flame the soot from the flame will be deposited on the outside of the beaker and it will take longer time to heat up the water.

Explanation:

n=3 is basically all the electrons in the 3rd energy level, so

3s=2

3p=6

3d=10

so total equals 18 electrons

n=5, l=1, refers specifically to the 5p

p has 3 orbitals so it can fill a total of 6 electrons

n=6, l=1, ml=-1,

so this refers to the 6p and since we have ml it refers to the specific orbital.

ml refers to the formula: -l -> l.

so in this case -1,0,1 ; these three numbers correspond to the 3 orbitals in the p subshell, each one can hold 2 electrons,

Thus, in this case the answers is 2

answer is 30 g!!!!!!!!!

Answer:

4.22 mol H₂O

Explanation:

Step 1: Write the equation for the synthesis of water

2 H₂ + O₂ ⇒ 2 H₂O

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of O₂ to H₂O is 1:2.

Step 3: Calculate the moles of water produced from 2.11 moles of oxygen

We will use the previously established molar ratio.

2.11 mol O₂ × 2 mol H₂O/1 mol O₂ = 4.22 mol H₂O

Answer:

Ksp = 4x³

Explanation:

Step 1: Write the reaction for the solution of calcium hydroxide

Ca(OH)₂(s) ⇒ Ca²⁺(aq) + 2 OH⁻(aq)

Step 2: Make an ICE chart

Let "x" be the molar solubility of calcium hydroxide.

        Ca(OH)₂(s) ⇒ Ca²⁺(aq) + 2 OH⁻(aq)

I                                 0                  0

C                              +x               +2x

E                                x                 2x

Step 3: Write the expression for the solubility product constant (Ksp)

The solubility product constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients.

Ksp = [Ca²⁺] × [OH⁻]² = x × (2x²) = x × 4x² = 4x³

if [tex]x[/tex] represents the molar solubility of  calcium hydroxide then  correct equation for the Ksp is [tex]\bold {x^3}[/tex]

Solubility product constant Ksp:

It is the equilibrium constant for a solid substance that are dissolved in an aqueous solution. It expresses how much a solute is dissolved in solution.

The reaction of calcium hydroxide for the solution  

[tex]\bold {Ca (OH )_2(s) \rightarrow Ca^2^+(aq) + 2 OH^-(aq)}[/tex]  

1 mole of calcium hydroxide is dissociate into 1 mole of calcium ion and 2 moles of Hydroxil ion.

The Ksp equation for the solution,

[tex]\bold {Ksp =[Ca^2^+][ OH^-]^2}\\[/tex]

If [tex]x[/tex] represents molar solubility,

[tex]\bold {Ksp =[x][ x]^2 = x^3}\\[/tex]

Therefore, if [tex]x[/tex] represents the molar solubility of  calcium hydroxide then  correct equation for the Ksp is [tex]\bold {x^3}[/tex]

Answer:

Mg is highly reactive as compared to that of Copper owing to its periodic position

Explanation:

MG lies in the second column of the periodic table while Cu lies in the 11th column of the periodic table from the left.

The elements in the first two columns are metallic in nature are highly reactive.

In CuCl2 solution, Mg being highly reactive replaces Cu but in MgCl2 solution, Cu being less reactive in nature do not replaces the Mg from the solution.

Answer: The new molarity of salt  in the photobacterium cell growth medium is 38.0 mM

Explanation:

According to the dilution law,

[tex]M_1V_1=M_2V_2[/tex]

where,  

[tex]M_1[/tex] = molarity of concentrated solution = 7.73 mM

[tex]V_1[/tex] = volume of concentrated solution = 23.5 ml  

[tex]M_1[/tex] = molarity of diluted solution = ?

[tex]V_1[/tex] = volume of diluted solution = 4.78 ml

Putting in the values we get:

[tex]7.73\times 23.5=M_2\times 4.78[/tex]

[tex]M_2=38.0mM[/tex]

Therefore, new molarity of salt  in the photobacterium cell growth medium is 38.0 mM

c. H₂​O (l) → H₂​O(s)

Explanation:

The correct answer is option C: The molecular formulas for the substance(s) on the left side of the equation and on the right side of the equation are identical. This means that there was not a chemical change, but a physical one.

In this concrete example, what happened was a change of states of matter: from liquid (l) to solid (s).

Other reactions have different molecular formulas on both sides of the equation, thus they represent chemical changes.

Answer:

Explanation:

First calculate how many moles of O2 you have. O is 16g/mole, so O2 is 32g/mole. 50/32 = 1.5625 moles. 1 mole of any gas at stp is 22.4 liters.

1.5625 × 22.4 = 35 liters.
