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?
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.

Explanation:
A sample of an oxide of nitrogen is found to contain 30.4% nitrogen. What is its empirical formula?
Answer:
If nitrogen = 30.4% then oxygen = 100-30.4 = 69.6%
divide each % value by atomic mass
N = 30.4/14 = 2.17
O = 69.6/16 = 4.35
Divide each y smaller:
N = 2.17/2.17 = 1
O = 4.35/2.17 = 2
Explanation:
"The empirical Formula will be [tex]NO_{2}[/tex]."
What is empirical formula?
In chemistry, an empirical formula is the simplest thought of the entire number quantity of atoms in a molecule.
It is given that N = 30.4%.
The % of O can be determined as: 100-30.4%= 69.65.
Now, after dividing % value with atomic mass, we get.
Mass of N= 14 and Mass of O = 16.
N= 30.4/14= 2.17
O = 69.6/ 16= 4.35
It can be seen that N has less number as compared to O . So, divide each with 2.17.
N= 2.17/2.17 = 1
O = 4.35/2.17=2
So the empirical formula will be [tex]NO_{2}[/tex].

Help I'll help y'all
heyyyyy.
Answer:
It's D, it is the horizon that contains the least humus.
Explanation:
I just did the test
The statement which correctly describes the soil horizon is option B. The horizon B contains the the smallest rock pieces. It is also called the subsoil layer.
What is soil horizon?Soil horizon contains different layers of soil which are classified based on the composition of the soil and the presence of rocks within the soil. The primary level of the soil is rich in humus. The decomposed of matter of plants and animals are called humus. On which the plants are growing.
The secondary level of soil horizon or the subsoil level contains some small rocks also onto which the roots of plants does not adhere so much. The third level of soil horizon contains bigger rocks with small gaps between them.
The last layer of the soil horizon is called bedrock layer containing bigger rocks with no significant gaps between them It is called the bedrock layer.

Are physical characteristics of an organism not genetically passed down?
In an ecosystem, the physical characteristics of an organism are genetically passed down from one generation to another.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

How many atoms are in 2.54 mole O?
Answer: 1.505 * 10^24 atoms
========================================================
Work Shown:
1 mole = 6.02 * 10^23 atoms
2.5*(1 mole) = 2.5*(6.02 * 10^23 atoms)
2.5 moles = (2.5*6.02) * 10^23 atoms
2.5 moles = (15.05) * 10^23 atoms
2.5 moles = (1.505 * 10^1) * 10^23 atoms
2.5 moles = 1.505 * (10^1*10^23) atoms
2.5 moles = 1.505 * 10^(1+23) atoms
2.5 moles = 1.505 * 10^24 atoms
This is true for any element. This value is an approximation since there are roughly 6.02 * 10^23 atoms in 1 mole of any element.

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
Answer:
5.5 L
Explanation:
First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:
10 g ÷ 44 g/mol = 0.23 molThen we use the PV=nRT formula, where:
P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K
V = 5.5 L83.0 g Lithium Cyanide (LiCN)

Answer:
7.34684 × 10^23 atoms
Explanation:
Well, one mole is basically
6.022 × 10^23 atoms. So 1.22 moles would be
6.022 × 10^23 ⋅ 1.22 atoms.
6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms
The total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant.Given:
1.22 moles of magnesium
[tex]1 \text{ mole}= 6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}= 1.22*6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}=7.34*10^{23}\text{ atoms}[/tex]

Collision of which two types of plates create the deepest earthquakes? Why do you think this is?
Answer:
The collision of oceanic plates and any other plates in which the oceanic plate slides beneath the other plate creates the biggest earth quakes. Most of these earth quakes occur beneath the sea or oceans and can cause volcanic eruptions as well. Tsunami is another oceanic event that occurs due to earth quakes occurring due to shifting of plates beneath the sea.
Can anyone tell me 5 reactions of metals with nonmetals?
non-Metals:
Nitrogen.
Oxygen.
Helium.
Sulfur.
Chlorine.
Explanation/Answer:
Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.
