Describe how innate behaviors and learned behaviors differ? If you tell me the answer i will give you a brainliest answer :)
Answer:
The difference between an innate behavior and a learned one is that innate behaviors are those an animal will engage in from birth without any intervention. Learned behavior is something an animal discovers through trial, error and observation.

why is CH3OH more polar than CH3CH2OH
Answer:
Explanation:
Polarity is about differencens in electronegativity. CH bonds have around the same electronegativity value so a CH bond is nonpolar. The more CH bonds there are in a molecule, the more nonpolar it is. Since CH3CH2OH has more carbon-hydrogen bonds than CH3OH, it is more nonpolar. With the same reasoning, since CH3OH has less CH bonds, it's more polar.

A sample of oxygen is collected in a 175 mL container over water at 15°C, and the barometer reads 752.0 torr.
What volume would the dry gas occupy at 770.0 torr and 15°C? (Water vapor pressure at 15°C is 12.8 torr.)
The volume of dry gas = 168 L
Further explanationGiven
175 ml container at 15°C
P total = 752 torr
water vapour = 12.8 torr
Required
The volume of dry gas
Solution
Dalton's law of partial pressure :
P tot = P₁ + P₂ + P₃ ....
P total = P O2 + P water
P O2 = 752 - 12.8
P O2 = 739.2 torr
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
P₁V₁ = P₂V₂
739.2 175 = 770 .V₂
V₂ = 168 L

what are the characteristics of temperature
A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. It measures the average kinetic energy of the substances also.
The average kinetic energy of the particles in an object is measured by its temperature. The velocity of these particles likewise increases as the temperature rises. A thermometer or a calorimeter is used to determine the temperature.
Our weather is made up of several various elements, including temperature, cloudiness, wind speed, and the quantity and type of moisture in the air.
Thus temperature determines the weather and kinetic energy.

What do scientists think is responsible for this dramatic change in height? Cite evidence from the text to support your answer.
Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

If 42.68 ml of 0.43 M KOH is used to neutralize 18.40 ml of H, SO4, calculate
the concentration of the sulfuric acid solution.
Write the net ionic equation of this reaction
The concentration of the sulfuric acid : 0.499 M
The net ionic equation
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]
Further explanationGiven
42.68 ml of 0.43 M KOH
18.40 ml of H2SO4
Required
the concentration of the sulfuric acid
the net ionic equation
Solution
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence
Input the value :
a=KOH, b= H2SO4
0.43 x 42.68 x 1 = Mb x 18.40 x 2
Mb = 0.499 M
The net ionic equation
Reaction
2KOH + H2SO4 → K2SO4 + 2H2O
2 K ⁺ (aq]+ 2 OH ⁻ (aq] + 2 H ⁺ (aq] + SO ₄²⁻(aq] → 2 K ⁺ (aq] + SO ₄²⁻(aq] + 2 H ₂ O (l]
canceled the spectator ions :
2 OH ⁻(aq]+ 2 H ⁺ (aq] → 2 H ₂O (l]
