what could cause a population of deer to decrease?

The bond between the Cu²⁺ and OH⁻ ions is, well, ionic. However, the bond between the O and the H in the OH⁻ ion is covalent. So Cu(OH)₂ is, as a whole, an ionic compound, but it contains or comprises both ionic and covalent bonds.

Answer:

Caustic Base

Explanation:

"Barium hydroxide forms a strong caustic base in aqueous solution. It has many uses, e.g., as a test for sulphides; in pesticides; in the manufacture of alkali and glass. Use of barium hydroxide lime rather than soda lime, high sevoflurane concentration, high absorbent temperature, and fresh absorbent use."

electromagnetic waves

Explanation:

The waves that do not need a medium to travel through are known as electromagnetic waves.

These waves do not need any medium for their propagation or traveling. The waves have different wavelength and energy factors depending upon their rate of propagation. EMR waves travel from the sun to the earth in space.

Examples of electromagnetic waves are Xrays, gamma rays, radio waves, and more.

Answer:

0.96

Explanation:

Number of moles of Fe(III) = 3/1000 *  0.002 M = 6 * 10^-6 moles

Number of moles of SSA = 7/1000 * 0.02 = 1.4 * 10^-4 moles

Total number of moles =  6 * 10^-6 moles +  1.4 * 10^-4 moles

Mole fraction of SSA = number of moles of SSA/ total number of moles.

Mole fraction of SSA =  1.4 * 10^-4 moles/  6 * 10^-6 moles +  1.4 * 10^-4 moles

Mole fraction of SSA = 0.96

Answer:

X5Y2

Explanation:

% composition of X = 52.2%

% composition of Y = (100 - 52.2) = 47.8%

This means that there are 52.2g of X and 47.8g of Y in the compound

To calculate the empirical formula of the compound, we first convert the gram value to mole value by dividing by their molar masses.

X = 52.2g/42.3g/mol = 1.234mol

Y = 47.8g/96.7g/mol = 0.494mol

Next, we divide each mole value by the smallest value (0.494mol)

X = 1.234mol ÷ 0.494mol = 2.49

Y = 0.494mol ÷ 0.494mol = 1

We multiply each value by 2

X = 2.49 × 2 = 4.98

Y = 1 × 2 = 2

The simple ratio of X:Y is 5:2, hence, their empirical formula is X5Y2.

This is true.

Explanation:

The mass of water present in the solution is 21.5 g.

Concentration refers to the amount of solute in a solution. There are various ways of expressing concentration such as;

We have the following information;

Percent concentration = 35.0 %

mass of solute = 40.0 g

Mass of water = ?

So;

35 = x/40 + x × 100/1

35 = 100x/40 + x

35(40 + x) = 100x

1400 + 35x = 100x

1400 = 100x - 35x

1400 = 65x

x = 1400/65

x = 21.5 g

Hence the mass of water is 21.5 g.

Answer:

2.00 M KOH

Explanation:

Divide moles by volume and make sure your volume is in LITERS, not mL.

0.0400 mol KOH / 0.0200 L = 2.00 M KOH

A sample of 0.0400 mol potassium hydroxide, KOH was dissolved in water to yield 20.0 ml of solution. The molarity of the solution is 2.00 M KOH.

Molarity is the measure of the concentration of any solute in per unit volume of the solution.

[tex]M = \dfrac{n}{V}[/tex]

Given, the 0.0400 mol potassium hydroxide

20.0 ml volume

Putting the values in the equation

[tex]\dfrac{0.0400 mol }{ 0.0200 ml} = 2 M[/tex]

Thus, the molarity of the solution is 2.00 M KOH.

Seasons are caused by the Earth’s revolution around the Sun, as well as the tilt of the Earth on its axis. The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter. During the warmer months, the Sun is higher in the sky, stays above the horizon for longer, and its rays are more direct.

Answer:

291.7167

Explanation:

The molar mass of Fe₂(CO₃)₃ is 291.714 g/mol.

To calculate the molar mass of Fe₂(CO₃)₃, we need to consider the atomic masses of the individual elements present in the compound.

The molar mass of each element is as follows:

Fe (iron): 55.845 g/mol

C (carbon): 12.011 g/mol

O (oxygen): 15.999 g/mol

Now, let's calculate the molar mass of Fe₂(CO₃)₃:

Molar mass = (2 × atomic mass of Fe) + (3 × atomic mass of C) + (9 × atomic mass of O)

Molar mass = (2 × 55.845 g/mol) + (3 × 12.011 g/mol) + (9 × 15.999 g/mol)

Molar mass = 111.69 g/mol + 36.033 g/mol + 143.991 g/mol

Molar mass = 291.714 g/mol

Therefore, the molar mass of Fe₂(CO₃)₃ is approximately 291.714 g/mol.

Answer:

7.61 liters

Explanation:

From the question,

Applying Charles law formula,

V₁/T₁ = V₂/T₂...................... Equation 1

Where P₁ = initial volume of of air, V₂ = Final volume of air, T₁ = Initial Temperature of air, T₂ = Final Temperature of air.

make V₂ the subject of the equation

V₂ = (V₁×T₂)/T₁............... Equation 2

Given: V₁ = 5 liters, T₁ -35 °C = (-35+273) K = 238 K, T₂ = 89°C = (89+273) K = 362 K

Substitute these values into equation 2

V₂ = (5×362)238

V₂ = 1810/238

V₂ = 7.61 liters

Answer:

7.59°C

Explanation:

Using the formula;

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to this question;

m = 80g

c = 4.2 J/g°C.

Q = 2550J

∆T = ?

Using Q = m × c × ∆T

∆T = Q/mc

∆T = 2550 ÷ (80 × 4.2)

∆T = 2550 ÷ 336

∆T = 7.589°C

The change in temperature of water = 7.59°C.
