Which statement best defines the term innate behavior?
behavior that is taught through watching others
behavior that is simple, untaught, and born knowing
behavior that is taught through both good and bad experiences
behavior that is untaught but very complex
Answer: behavior that is simple, untaught, and born knowing
Have a nice dam day!!
The term that describes innate behavior is:
D. behavior that is untaught but very complex
What does innate behavior stand for?Intr-insic or "intuitive" ways of behaving are innate and don't need learning or related knowledge to be performed. Models incorporate romance and ways of behaving, departure and guarded moves, and hostility. Movement and Migration Innate or ins-tinctual behaviors rely on response to sti-muli.
Thus, option D is correct.

Think about the decomposition reaction of ozone.
2 O3 ----> 3 O2
If 71.7 mol ozone are in this reaction, what is the theoretical yield of O2 (in gram)?
Answer:
3441.6 grams.
Explanation:
2 O₃ → 3 O₂
First we convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂), using the stoichiometric coefficients of the reation:
71.7 mol O₃ * [tex]\frac{3molO_2}{2molO_3}[/tex] = 107.55 mol O₂
Then we convert 107.55 moles of O₂ into grams, using the molar mass of O₂:
107.55 mol * 32 g/mol = 3441.6 g
Excessive use of chemical fertilizer causes chemical pollution.how?
Answer:
Chemical fertilizers contain various chemicals that cause harm to soil and water.
Explanation:
Chemical fertilizers contain various chemicals such as phosphates, nitrates which can cause water pollution. Eutrophication caused by the environmental nitrogen and phosphorous that causes rich minerals and chemicals in the water.
These can cause excessive growth of the algae and phytoplankton that will cause depletion of the oxygen from the water body and organisms will die due to this.

How many kilojoules of energy are required to heat 50.0 g of ethyl alcohol from 60.0 °C to 78.4 °C and vaporize it? The specific heat of ethyl alcohol is 2.138 J/g°C; heat of vaporization is 853 J/g.
Answer:
44.62 kJ
Explanation:
Firstly, we calculate the energy needed to heat the liquid (ethyl alcohol) by using the formula:
Q = m × c × ∆T
Where;
Q = Amount of heat (J)
m = mass (g)
c = specific heat of ethyl alcohol = 2.138 J/g°C
∆T = change in temperature (°C)
According to the information given in this question;
Q = ?, m = 50.0g, ∆T = (78.4°C - 60°C) = 18.4°C
Therefore, using Q = mc∆T
Q = 50 × 2.138 × 18.4
Q (amount of energy needed to heat ethyl alcohol) = 1966.96 J
Next, we calculate and add the amount of heat needed to vaporize by using the formula;
How many kilojoules of energy are required to heat 50.0 g of ethyl alcohol from 60.0 °C to 78.4 °C and vaporize it? The specific heat of ethyl alcohol is heat of vaporization is 853 J/g.

If 36.0 g of NaOH (MM = 40.00 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the concentration of NaOH in the resulting solution
Answer:
Molarity of NaOH = 1.8 M.
Explanation:
From the question given above, the following data were obtained:
Mass of NaOH = 36 g
Molar mass of NaOH = 40 g/mol
Volume = 500 mL
Molarity of NaOH =?
Next, we shall determine the number of mole in 36 g of NaOH. This can be obtained as follow:
Mass of NaOH = 36 g
Molar mass of NaOH = 40 g/mol
Mole of NaOH =?
Mole = mass / molar mass
Mole of NaOH = 36 / 40
Mole of NaOH = 0.9 mole
Next, we shall convert 500 mL to L. This can be obtained as follow:
1000 mL = 1 L
Therefore,
500 mL = 500 mL × 1 L / 1000 mL
500 mL = 0.5 L
Finally, we shall determine the molarity of NaOH. This can be obtained as follow:
Mole of NaOH = 0.9 mole
Volume = 0.5 L
Molarity of NaOH =?
Molarity = mole / Volume
Molarity of NaOH = 0.9 / 0.5
Molarity of NaOH = 1.8 M
1. Density is the measure of how much
volume ?????? is contained in a given volume
Explanation:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).

a) How do you prepare %3 (w/v) Na2CO3 solution from Na2CO3⸱2H2O? (15p) Na2CO3 MW=106 g/mol
Answer:
4.02g of Na2CO3⸱2H2O must be added completing the volume of the solution to 100mL
Explanation:
A 3%(w/v) solution contains 3g of solute (In this case, Na2CO3) in 100mL of solution.
Assuming we require 100mL of solution we must add 3g of Na2CO3. The reactant that is available is its dihydrate, with molar mass:
106g/mol + 2*MW H2O
106g/mol + 2*18g/mol = 142g/mol
That means the mass of Na2CO3.2H2O that must be added to prepare the solution is:
3g Na2CO3 * (142g/mol Na2CO3.2H2O / 106g/mol Na2CO3) =
4.02g of Na2CO3⸱2H2O must be added completing the volume of the solution to 100mLA sample of polonium-210 has an initial mass of 390 milligrams (mg). If the half-life of polonium-210 is 36 days, how many mg of the sample remains after 36 days?

Explanation:
Lattice energy is Question 4 options: the energy given off when gaseous ions combine to form one mole of an ionic solid the energy required to convert a mole of ionic solid into its constituent ions in the gas phase the energy required to produce one mole of an ionic compound from its constituent elements in their standard states the sum of ionization energies of the components in an ionic solid the sum of electron affinities of the components in an ionic solid
Answer:
Lattice energy is the energy required to convert a mole of ionic solid into its constituent ions in the gas phase
Explanation:
Lattice energy is usually calculated by the Born-Haber cycle, from the affinity energies and sublimation ethalphy values. It is used as an estimation of the ionic energy strength between the ions in an ionic compound.
It is defined as the energy needed to broke 1 mol of a given ionic compound into its ions in the gaseous state. For example, the lattice energy for sodium chloride (NaCl) is the energy required to separate 1 mol of solid ionic compound (NaCl(s)) and produce the sodium and chlorine ions in the gas phase: Na⁺(g) and Cl⁻(g).
Which of the following regions has an economy based on processing food and consumer goods?
A. Western Europe
B. Eastern Europe
C. northern Europe
D. southern Europe
No links plz
Answer:
B. Eastern Europe
Explanation:
The economy of Eastern Europe depends on producing foods. For example, Poland and Belarus are two countries in Eastern Europe, and they both produce chocolates. Producing foods isn't the only detrimental part of the region's economic data. The other half depends on consumer goods. For example, Estonia and Latvia are good countries in packaging food. The answer to the question is B.
If a substance has a density of 0.123 g/mL, 10.0 dL would weigh in g?
Answer:
123 g
Explanation:
First, we convert 10.0 dL into mL, keeping in mind that:
1 dL = 100 mL; then10.0 dL * 100 = 1000 mLNow we can multiply the density by the volume in order to calculate the mass:
Density = mass / volumeDensity * volume = mass0.123 g/mL * 1000 mL = 123 g10.0 dL of a substance with a density of 0.123 g/mL would weigh 123 grams.

What mass or iron is needed to react with 30.0g of oxygen? Could you show me how you got that answer?
Answer:
The mass of iron needed to react with the oxygen is 70 g.
Explanation:
The balanced chemical reaction between iron and oxygen is given as;
4Fe + 3O₂ ----------> 2Fe₂O₃
Molecular mass of 3O₂: 3(16 x 2) = 96 g
Molecular mass of 4Fe: 4(56) = 224 g
96 g of O₂ ---requires--------> 224 g of Fe
30 g of O₂ -------requires--------->? Fe
= (30 x 224) / 96
= 70 g
Therefore, the mass of iron needed to react with the oxygen is 70 g.
