Write a question you have about Titan or about methane that could help you determine what happened to the lake
Answer: what would swimming in mathane lake on titan feel like.
Explanation:
Both methane and titan are gases that are combustible in nature.
Those gases which are inflammable are called combustible gases.
For example:-
MethaneEthaneThese gases have various uses in daily life. these uses as follows:-
CookingDecompositionUsed as fuelThe gas will mix in the lake which harms the aquatic animals. The aquatic animals have a hard time to breath.
Hence, the lake will be polluted.

Given the reaction: 4 NH3(g) + 5 O2(g) → 4 NO (g) + 6 H2O When 1.20 mole of ammonia reacts, how many moles of water are produced?
Answer:
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.
Explanation:
The balanced reaction is:
4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O
By stoichiometry of the reaction, the following amounts of moles participate in the reaction:
NH₃: 4 moles O₂: 5 molesNO: 4 molesH₂O: 6 molesThen you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?
[tex]moles of water=\frac{1.2 moles of ammonia*6 moles of water}{4 moles of ammonia}[/tex]
moles of water= 1.8 moles
When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.
Please help me with this!
Answer:
3.01x10^23
Explanation:
In order to determine the amount of molecules, you have to use Avogadro's number which = 6.02x10^23. To calculate this, multiply the number of moles with Avogadro's number to get the above answer.
Hope this helps!
An -ate or -ite at the end of a compound name ususally indiates that the compound contains...
Answer: Oxygen.
Explanation: The -ate is used for the ion that has the largest number of Oxygen atoms. The -ite would be used for the ion with the smaller amount of oxygen atoms.
What do you think happens to the bonds between atoms when substances melt?
Answer:
As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other. The intermolecluar forces holding the molecules together become weaker. This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.

which elements are out of order in terms of atomic mass. co,Ni or Li,be or I,xe
Answer:
The pair co,Ni is out of order in terms of atomic mass
Explanation:
For co,Ni
Atomic mass of Co = 58.9331 u
Atomic mass of Ni = 58.6934
For Li,be
Atomic mass of Li = 6.941 u
Atomic mass of be = 9.012182 u
For I,xe
Atomic mass of I = 126.90447 u
Atomic mass of Xe = 131.293 u
Hence, the pair co,Ni is out of order in terms of atomic mass

Why might the ability to produce three-dimensional images of organs be helpful in diagnosing a patient's ailment?
Answer:
Explanation: The body is largely composed of water molecules. Each water molecule has two hydrogen nuclei or protons. MRI takes advantage of the high prevalence of hydrogen in the body and the magnetic properties of the proton in a hydrogen atom. Hydrogen atoms induce a small magnetic field due to the spin of this atom's proton.

Create the Equation: How many grams of Aluminum Chloride would be made from 42.7 L of Chlorine gas at STP reacting with 50.0 g of Aluminum?
Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
moles of [tex]Al[/tex]
[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]
moles of [tex]Cl_2[/tex]
According to ideal gas equation:
[tex]PV=nRT[/tex]
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 42.7 L
n = number of moles = ?
R = gas constant =[tex]0.0821Latm/Kmol[/tex]
T =temperature =[tex]273K[/tex] (at STP)
[tex]n=\frac{PV}{RT}[/tex]
[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]
[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]
According to stoichiometry:
3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium
Thus 1.90 moles of [tex]Cl_2[/tex]reacts with= [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium
Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.
As 3 moles of [tex]Cl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]
Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex] of [tex]AlCl_3[/tex]
Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]
Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
