If one of the cars began with 5.6 liters of gasoline and oxygen, how much water and carbon dioxide do you think would be produced from that gasoline and oxygen?
Answers
Answer
5.6 L
Explanation:
whatever you start with, you end with the same amount.
(LAW OF CONSERVATION)
The amount of oxygen and gasoline that can be produced is 5.6 liters
The question above is answered with the law of conversation of mass. This law of conversation of mass states that no form of energy can be destroyed, instead it is changed from one form to another type of form.
In this law, it is expected that you end with the same amount you started with. According to the question above, since the amount that you started with is 5.6 liters then you will end with 5.6 liters also.

============================================
Work Shown:
Using the periodic table, we see that
1 mole of carbon = 12 grams1 mole of oxygen = 16 gramsThese are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.
So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.
-------------------
Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.
11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2
In short,
11.0 grams of CO2 = 0.250 mol of CO2
This is approximate.
We don't need to use any of the information in the table.

is there a relationship between the relative age of stars in the number/identity of element is found within them
Answers
Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.

Convection currents in the air.
This phenomena is called an offshore breeze. At night, land is cooling faster than water; the air above the land also cools and, therefore, its density grows. As a result, the pressure above the land is greater than above the water, and the air moves from the regions with higher pressure (land) to the ones with lower pressure (water).
In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder and the water level increases from 28.2 mL to 31.4 mL. What is the density of the metal ball? (round you answer to the nearest hundredth)
Answers
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml

A thermochemical equation indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by a triangle H does this term stand for?
Answers
Answer:
A. Enthalpy of the reaction
Explanation:
A Thermochemical equation is a balanced stoichiometric chemical equation that indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by ΔH, a this term which stands for the enthalpy change, ΔH.
The Enthalpy of Reaction or Heat of Reaction is the amount of energy in the form of heat transferred during a chemical reaction that occurs at a constant pressure. It is useful for calculating the amount of energy per mole either released or produced in a reaction, therefore is unit is kJ/mol.
In a reaction where energy is absorbed by the reactants during the formation of products, ΔH is positive. On the other hand, in a reaction where energy is released by the reactants during the formation of products, ΔH is negative.
The enthalpy change, ΔH of reactions are determined experimentally under standard conditions of 1 atm and 25 °C (298.15K). Enthalpy can be measured experimentally through the use of a calorimeter. A calorimeter is an isolated system which has a constant pressure and in which heat loss to the surroundings is minimal.
