Answer:
I believe that would be methane! I hope this helps you!
Answer:
methane
Explanation:
The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). Natural gas also contains smaller amounts of natural gas liquids (NGL, which are also hydrocarbon gas liquids), and nonhydrocarbon gases, such as carbon dioxide and water vapor.The main component in natural gas is methane. It also has ethane, propane, butane, hydrocarbons.

The Russian Mir space station used a chemical oxygen generator system to make oxygen for the crew. The system ignited a tube of solid lithium perchlorate (LiClO4) to make oxygen and lithium chloride (LiCl): LiClO4 (s) 2O2 (g) + LiCl (s) If you have 300 g of LiClO4, then… (a) How many moles of oxygen gas will be generated?
(b) The station’s standard operating conditions are a pressure of 101.5 kPa and a temperature of 21°C. Based on this information and your answer to part (a), how many liters of oxygen gas will be generated? (Show your work.)
300 g of LiClO₄ produce 5.64 moles of O₂, which is equivalent to 136 L of O₂ at 101.5 kPa and 21 °C.
Let's consider the following balanced equation.
LiClO₄(s) ⇒ 2 O₂(g) + LiCl(s)
We can calculate the moles of O₂ produced from 300 g of LiClO₄ using the following relationships.
The molar mass of LiClO₄ is 106.39 g/mol.The molar ratio of LiClO₄ to O₂ is 1:2.[tex]300 g LiClO_4 \times \frac{1molLiClO_4}{106.39gLiClO_4} \times \frac{2molO_2}{1molLiClO_4} = 5.64molO_2[/tex]
Then, we will convert 101.5 kPa to atm using the conversion factor 1 atm = 101.325 kPa.
[tex]101.5 kPa \times \frac{1 atm}{101.325kPa} = 1.002atm[/tex]
Next, we will convert 21 °C to Kelvin using the following expression.
[tex]K = \° C + 273.15 = 21\° C + 273.15 = 294 K[/tex]
Finally, we will calculate the volume occupied by 5.64 moles of oxygen using the ideal gas equation.
[tex]P \times V = n \times R \times T\\\\V = \frac{n \times R \times T}{P} = \frac{5.64 mol \times (\frac{0.082atm.L}{mol.K} ) \times 294K}{1.002atm} = 136 L[/tex]
300 g of LiClO₄ produce 5.64 moles of O₂, which is equivalent to 136 L of O₂ at 101.5 kPa and 21 °C.

The two boron atoms listed in the table are isotopes of the boron. The two carbon atoms and the two oxygen atoms are also called isotopes. Based on the patterns in the particle compositions of these atoms, write a definition for “isotopes”
Answer:
A type of an atom which has a different number of neutrons but the same atomic number, therefore making it the same element. This atom would still have the same properties as well. (Ex: Vanadium-51 is an isotope of Vanadium that has 51 neutrons but still has 23 protons, as its atomic number is 23.)
Isotopes are variants of an element that have the same number of protons in their atomic nucleus, identifying them as the same chemical element, but differ in the number of neutrons.
The variations in neutron numbers among isotopes lead to differences in their atomic masses, resulting in isotopes having slightly different physical properties while retaining similar chemical behavior.
For example, in the case of boron, the two isotopes listed may have the same number of protons (5), but one has 6 neutrons, and the other has 7 neutrons, leading to slightly different atomic masses.
Similarly, for carbon and oxygen, the isotopes exhibit variations in neutron numbers while maintaining the same number of protons, defining them as isotopes of the respective elements. Isotopes play a crucial role in various scientific fields, including radiometric dating, nuclear energy, and medical imaging.

What is the mass % of acetone in a 1.85 M solution of acetone (MM = 58.08 g/mol) in water? The density of the solution is 0.971 g/mL.
A 1.85 M acetone solution (MM = 58.08 g/mol) with a density of 0.971 g/mL has a mass percent of acetone of 11.0%.
What is the mass percent?It refers to the mass of solute in 100 grams of solution.
Let's suppose we have 1 L of the solution.
Step 1: Calculate the mass of solute (acetone).We have a 1.85 M solution of acetone (MM = 58.08 g/mol). We will calculate the mass of acetone using the following expression for molarity.
M = mass acetone / MM acetone × liters solution
mass acetone = M × MM acetone × liters solution
mass acetone = 1.85 mol/L × 58.08 g/mol × 1 L = 107 g
Step 2: Calculate the mass of the solution.We have 1 L (1000 mL) of the solution with a density of 0.971 g/mL.
1000 mL × 0.971 g/mL = 971 g
Step 3: Calculate the mass percent of acetone.%acetone = (107 g/971 g) × 100% = 11.0 %

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. The water level rises to the 49.10 mL mark. From this information, calculate the density of iron.
HELLPPP CAN SOMEONE SOLVE THIS???
Answer:
Density if iron shot = 7.92 g/ml (2 sig. figs.)
Explanation:
By definition, density is mass per unit volume. That is,
Density (D) = mass(m)/Volume(V)
mass(m) = 28.5g (given)
Volume(V, of iron shot) = 49.10ml - 45.5ml = 3.6ml
Substitutuing into D = m/V = 28.5g/3.6ml = 7.9166667 g/ml (calc.ans)
≅ 7.92 g/ml (2 sig. figs.)

what happens to a circuits resistance (R), voltage (V), and current (I) when you increase the diameter of the wire in the circuit?
a. R increases, V is constant, I increases
b. R decreases, V is constant, I increases
c. R decreases, V increases, I increases
d. R increases, V decreases, I decreases
Answer:
b. R decreases, V is constant, I increases
Explanation:
when we increase the diameter of wire increases ,resistance decreases and current increases.Therefore, the option is b.
Resistance is an electrical quantity which opposes the electric current in the circuit. Resistance is directly proportional to the length of the wire and inversely proportional to the diameter of the wire. If length of wire increases resistance will increases and if the diameter of the wire increase resistance will decreases.
R = ρ L/A
Here ρ is the resistivity
L is the length of the wire
A is the cross-sectional area of wire/diameter of the wire
Voltage is the potential difference between two terminals of voltage source. Current is the flow of electrons in the circuit. Voltage is the product of current and resistance.
V=IR
Rewrite the above equation interms of current
I=V/R
From the above equation we can say that current is inversly proportional to the resistance.Therefore,the correct option is b.

It is important to understand that while the absorbance value is related to the amount of light absorbed by a sample, it is not equal to or directly proportional to the amount of light absorbed. Consider a situation where 100 photons of light pass through a sample. After the light passes through the sample, 64 photons are detected. a) How many photons were transmitted through the sample
When 100 photons of light pass through a sample and 64 photons are detected after the passage of light, the number of photons transmitted through the sample is 64.
This is based on the methods of calculating the absorbance of light, which is depicted as the higher the amount of light transmission, the lower the amount of light absorbed.
Thus, when 64 photons of light in 100 photons are detected, 64 photons are transmitted, and therefore, the number of photons absorbed is 36.
Hence, hypothetically, if 100 photons of light are transmitted, 0 photons of light will be absorbed.
Therefore, in this case, it is concluded that the correct answer is 64 photos.

similarities between viruses and fungi
Answer:
I can't think of any similarities at all.
Viruses are just an aggregation of genomic material and protein. Occasionally lipid folds around it to make a covering called an envelope.
Fungi are living, eukaryotic cells that metabolize, grow, perform energy conversions and mate with each other.

E = 6.6 × 10^-34 Js × 3 × 10^8 m/s / 270 × 10^-9
E = 7.33 × 10^-19 J
For the lower range;
E = ?

Explanation:
The lava, itself (when liquid) is very much above the boiling point of water, so it is not wet with liquid water, so it's a no in that sense,' he writes. ...
