Taking into account the reaction stoichiometry, 5 moles of CO₂ can be formed from 1.25 mol butane and excess oxygen.
Reaction stoichiometryIn first place, the balanced reaction is:
2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
C₄H₁₀: 2 moles O₂: 13 moles CO₂: 8 molesH₂O: 10 molesMoles of CO₂ formedThe following rule of three can be applied: if by reaction stoichiometry 2 moles of C₄H₁₀ form 8 moles of CO₂, 1.25 moles of C₄H₁₀ form how many moles of CO₂?
[tex]moles of CO_{2} =\frac{1.25 moles of C_{4} H_{10}x8 moles of CO_{2}}{2 moles of C_{4} H_{10}}[/tex]
moles of CO₂= 5 moles
Then, 5 moles of CO₂ can be formed from 1.25 mol butane and excess oxygen.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law?
- High pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker
- High pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant
- Low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker
- Low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
Answer:
High pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant
Answer:
A gas at very low volumes, when gas particles are very close together
A gas at very low temperatures, when gas particles have very little kinetic energy
A gas with highly polar molecules that have very strong inter-molecular forces
Explanation:
According to kinetic molecular theory:
a) Ideal gases have large number of particles which were considered to be hard spherical objects.
b) these gas particles move randomly in a straight line.
c) the path of gas particles change when they collide with each other or walls of vessel.
d) there is no or negligible inter molecular interactions between the gas particles.
e) the inter molecular distances is much higher than the size of particles.
f) the gas particles occupy negligible volume of the vessel.
g) during collision of gas particles is perfectly elastic.
h) the average kinetic energy of particles is constant at a constant temperature. It varies directly with the temperature.

The surface tension of water _is because it's molecules form_.
Answer:
Hello! I am very sorry I do not know the exact answer to this but here is some information that may help!
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. This inward net force causes the molecules on the surface to contract and to resist being stretched or broken.
Explanation:

2. A submarine is able to raise and lower itself
underwater. A rock sinks when it is dropped in a
pool because it is denser than water. A piece of
wood floats in the pool because it is less dense
than water. What could the submarine change in
order to sink or float? Choose all that apply.
A. the submarine's volume
B. the submarine's mass
C. the state of the surrounding water
D. the mass of the surrounding water
Answer:
I think it's the state of the surrounding water because if the water holds impurities it will float and if it doesn't have impurities it will sink
A submarine is able to raise and lower itself underwater. A rock sinks when it is dropped in a pool because it is denser than water. A piece of wood floats in the pool because it is less dense than water. If we want to change in sink or float of submarine then we must change the state of surrounding water. Thus, option c is correct.
How a submarine is float in water while a small stone is sink in water?According to Archimedes's principle the upward buyout force that is exerted on a body immersed in a fluid whether fully or partially, is equal or less than the fluid that the body displaces.
Mathematically
Buyout force = Fb=-pgv
Where
p= density of fluid
g= acceleration due to gravity
v = Volume of fluid
So, if a object is floating in the water then buyout forces must be equal to their weight, and for that weight of water that is displaced by object must be greater than or equal to the weight of object. So object is floating.
Therefore, a submarine is able to raise and lower itself underwater. A rock sinks when it is dropped in a pool because it is denser than water. A piece of wood floats in the pool because it is less dense than water. If we want to change in sink or float of submarine then we must change the state of surrounding water. Thus, option c is correct.

Answer:
1. oxygen gas
2. Asteroid and comet bombardment had
increased
3. A secondary atmosphere is an atmosphere of a planet that did not form by accretion during the formation of the planet's star. A secondary atmosphere instead forms from internal volcanic activity, or by accumulation of material from comet impacts.
The climate of the Quaternary period showed several decreases in global temperature (glacial periods) separated by warm (interglacial) periods. Core samples taken from sea beds elude to at least sixteen glaciations during the Quaternary period.
A primary atmosphere is an atmosphere of a planet that forms by accretion of gaseous matter from the accretion disc of the planet's sun. Planets such as Jupiter and Saturn have primary atmospheres. Primary atmospheres are very thick compared to secondary atmospheres like the one found on Earth.
Now we have Earth's “third atmosphere,” the one we all know and love—an atmosphere containing enough oxygen for animals, including ourselves, to evolve. So plants and some bacteria use carbon dioxide and give off oxygen, and animals use oxygen and give off carbon-dioxide—how convenient!

The chemical equation below shows the decomposition of nitrogen triiodide (ni3) into nitrogen (n2) and iodine (i2). 2ni3 right arrow. n2 3i2 the molar mass of ni3 is 394.71 g/mol. how many moles of i2 will form 3.58 g of ni3? 0.00907 moles 0.00940 moles 0.0136 moles 0.0212 moles
The moles of diiodine is formed from the nitrogen triiodide is 0.0212 moles.
How we calculate moles from mass?Relation between the moles and mass of any substance will be represented as:
n = W/M, where
n = moles
W = given mass
M = molar mass
Given chemical reaction is:
2NI₃ → N₂ + 3I₂
Moles of 5.58g of NI₃ will be calculated as:
n = 5.58g / 394.71g/mol = 0.0141 mole
From the stoichiometry of the reaction, it is clear that:
2 moles of NI₃ = produce 3 moles of I₂
0.0141 moles of NI₃ = produce 3/2×0.0141=0.02115 = 0.0212 moles of I₂
Hence option (4) is correct i.e. 0.0212 moles.

A 5.00-wt% aqueous sulfuric acid solution (p=1.03 g/ml) flows through a 45-m long pipe with a 6.0 cm diameter at a rate of 82 L/min. a) What is the molarity of sulfuric acid in the solution? b) How long in seconds) would it take to fill a 55-gallon drum, and how much sulfuric acid (lbm) would the drum contain? c) The mean velocity of a fluid in a pipe equals the volumetric flow rate divided by the cross-sectional area normal to the direction of flow. Use this information to estimate how long (in seconds) it takes the solution to flow from the pipe inlet to the outlet.
Answer:
Explanation:
a )
5 gram of sulfuric acid in 100 gram of solution
volume of 100 gram of solution = 100 / 1.03 ml
= 97.08 ml = .097 L
5 gram of sulfuric acid = 5 / 98 moles = .051 moles
.051 moles in .097 L solution
molarity = .051 / .097 = .525 M .
b ) 55 gallon = 3.7854 x 55 L = 208 L
rate of flow = 82 L / min
time taken to fill the drum = 208 / 82 min = 2.536 min .
volume of sulfuric acid = 208 L
mass = volume x density = 208 x 1000 x 1.03 gram = 214.24 kg
214.24 kg = 214.24 x 2.2 lb = 471.33 lb
c )
cross sectional area = 3.14 x 3² = 28.26 cm²
rate of flow = 82 L / min = 82 x 1000 cm³ / min
= 82000 / 60 cm³ / sec = 1366.67 cm³ / s
velocity = 82 x 1000 / 1366.67 = 60 cm / s = .6 m / s
length of pipe = 45 m
time taken = 45 / .6 = 75 s
10.Which device is designed to produce
mechanical energy?
(1) a fan
(2) a battery
(3) a lamp
(4) an oven
Which device is designed to produce mechanical energy?
Well, mechanical energy is the sum of potential and kinetic energy. Kinetic energy is a unit of energy in which is the reason why an object does movement, while potential energy is another unit of energy in which is the reason why an object doesn't move, or stops. While you can stop a fan or a lamp, it isn't automatic. It's manually. So the answer is (4) an oven because mechanical energy happens automatically, not manually, or for a greater reason.

How much space does 750.00 g of a substance occupy it if has a density of 0.78 g/mL?
Answer:
The substance occupy 961.54 cm³ space.
Explanation:
Given data:
Mass of substance = 750.00 g
Density of substance = 0.78 g/mL
How much space it occupy = ?
Solution:
The space occupy by the substance is equal to its volume. Thus we will calculate the volume by applying density formula. Which is actually the space cover by substance.
d = m/v
d = density
m = mass
v = volume
0.78 g/mL = 750.00 g/ v
v = 750.00 g/ 0.78 g/mL
v = 961.54 mL
1 mL = 1 cm³
v = 961.54 cm³
Thus substance occupy 961.54 cm³ space.
