Name (3) ways an animal can use energy from food?
Answer:
The food chain begins with the sun: plants get their energy by photosynthesizing sunlight into energy, and then herbivores eat those plants to get their energy. Carnivores who then eat the herbivores are getting that sunlight passed along from sun to plant to herbivore to carnivore.

Explanation:
What is temperature?
Answer: Temperature is an objective measurement of how hot or cold an object is. It can be measured with a thermometer or a calorimeter. It is a means of determining the internal energy contained within a given system.
Explanation:
Answer:
Temperature is a physical quantity that expresses hot and cold
Explanation:
Temperature is a physical quantity that expresses hot and cold. This is how the air feels and how hot/cold something is. The less tight the atoms are, the hotter something is. The more tight the atoms are, the cooler something is.

Explanation:
One gallon of gasoline (C8H18) weights about 6.3 pounds. Burning gasoline with excess of oxygen forms water and carbon dioxide. When 3.1 gallons of gasoline burn, how many pounds of CO2 emit into the air?
FW: C = 12; H = 1; O = 16.
Answer:
60 pounds of CO₂ are emited into the air
Explanation:
The combustion of gasoline occurs as follows:
C₈H₁₈(l) + 25/2O₂(g) ⇄ 8CO₂(g) + 9H₂O
Where 1 mole of gasoline produce 8 moles of CO₂
To solve this question we must find the moles of gasoline in 3.1 gallons. 8 times these moles are the moles of CO₂ produced. With the moles of CO₂ we can find its pounds as follows:
Pounds gasoline:
3.1 gallons * (6.3 pounds / gallon) = 19.53 pounds
Grams gasoline:
19.53 pounds * (453.592g / pound) = 8859g
Moles gasoline -Molar mass C8H18: 114.23g/mol-
8859g * (1mol / 114.23g) = 77.55 moles gasoline
Moles CO₂:
77.55 moles gasoline * (8 mol CO₂ / mol Gasoline) = 620.4 moles CO₂
Mass CO₂ - Molar mass: 44.01g/mol-
620.4 moles CO₂ * (44.01g / mol) = 27304g CO₂
Pounds CO₂:
27304g CO₂ * (1lb / 453.592g) =

Which statement describes a physical property of copper?
Answer:
Copper is typically a solid and has a coppery, bronzy color. It is a metal and has a relatively high melting point. It has a strong luster and can conduct electricity.
Answer:
RESHAPE BY A FORCE.
Explanation:
1. It can be reshaped by a force. Physical property can be observed and measured without any changes in molecular composition.
2. A physical property is one that can be change without altering the identity of the substance. These set of properties is not concentration dependent they are use to describe matter. Example are: density, solubility, melting point and color and odor. For this case the second option seems to fit the description it can be reshape by force.

What is the maximum number of electrons that can be identified with each of following sets of quantum numbers? If there are none, enter 0.
Answer:
So, only one electron is there with n = 0, l = 0 and its quantum set is n = 0, l = 0, ml = 0, ms = -1/2. Hope, this is helping. The maximum number of electrons that can fit inside a 'n' shell is 2n^2. So it would be 1.
Explanation:
Quantum numbers are defined as the set of four numbers with the help of which we can get complete information about the electrons in an atom. Here the term 'n' represents the principal quantum number.
What is principal quantum number?The quantum number which represents the main energy level or shell in which electrons are present. It also determines the average distance of orbital or electron from the nucleus. It can have the whole number values like 1,2,3,4, ....
1. When n = 2, the maximum number of electrons present is 8. That is one 's' sub level and three 'p' sub levels. The spin of four electrons will be +1/2 and other four will be -1/2.
2. When l = 3, the possible orientations = 2l + 1 = 2(3) + 1 = 7. So the maximum number of electrons is 14.
3. The value of ml = -1 indicates only one orbital. So the maximum electrons is 2.
4. Here ml = -1, 0, 1 which shows three orbitals. So in ml = -1, there are only two electrons.
