Answer:
3.400 mol C₃H₈
Explanation:
Step 1: Write the balanced equation
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
Step 2: Establish the appropriate molar ratio
The molar ratio of C₃H₈ to H₂O is 1:4.
Step 3: Determine the moles of C₃H₈ needed to produce 13.60 moles of H₂O
We will use the previously established molar ratio.
13.60 mol H₂O × 1 mol C₃H₈/4 mol H₂O = 3.400 mol C₃H₈

What is Collision theory?The collision theory states that each and every chemical reaction can occur between particles when the molecules collide each other.
The collision between particles is necessary but it is not sufficient for a reaction to take place. The collisions must be effective.
It is necessary to know the exact nature of an effective collision since this indicates whether particles react with each other and form new products.
According to collision theory, the reaction occur when molecules collide and molecules have sufficient activation energy to cross energy barrier.
Greater the energy, greater will be number of collision. Lesser energy, lesser will be number of collision.
Thus, the given energy diagram shows about the energy required for a reaction to take place.

What characterizes Stage 2 of the demographic transition seen in developed countries?
a. a low birth rate
b. a high death rate
c. a low growth rate
d. a high growth rate
Answer:
The correct answer is - D. a high growth rate.
Explanation:
The DTM or Demographic Transition Model which has a various stage that tells about the demography of the nation. It is a model used by the USA. According to this model, different nations or countries show demographic similarities on the basis of their development. Stage 2 is the stage where most of the least developed countries are present.
In this stage of DTM, the death rate is very less and the birth rate of the population of the country is high so therefore their population shows rapid growth and increases.
of the Demographic Transition Model (DTM) is characterized by a rapid decrease in a country's death rate while the birth rate remains high. As such, the total population of a country in Stage 2 will rise because births outnumber deaths, not because the birth rate is rising.
What is the Empirical Formula when the Molecular Formula is Sb17Br21
Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

define and explain sublimation and name the substance that sublime directly on heating
Answer:
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... So, all solids that possess an appreciable vapour pressure at a certain temperature usually can sublime in air (e.g. water ice just below 0 °C).

What happens on a molecular level when a diatomic molecule is a gas but is then cooled to a solid?
Answer:
As an example of the processes depicted in this figure, consider a sample of water. When gaseous water is cooled sufficiently, the attractions between H2O molecules will be capable of holding them together when they come into contact with each other; the gas condenses, forming liquid H2O. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass.

What is the capillary rise of ethanol in a glass tube with a 0.1 mm radius if the surface tension of ethanol is 0.032Jm2 and the density of ethanol is 0.71gcm3
Answer:
Explanation:
Expression for capillary rise is as follows
h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.
T = .032 J m⁻²
ρ = .71 g / cm³
= 7100 kg / m³
r = .1 x 10⁻³ m = 10⁻⁴ m
h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )
h = .0092 m
= 9.2 mm .

Given 25.43 g of O2 gas, how many liters of gas will you have at STP?
Answer value
Given :
Mass of O₂, m = 25.43 g.
To Find :
How many liters of gas will you have at STP.
Solution :
Molecular mass of O₂, M.M = 2 × 16 gram/mole
M.M = 32 gram/mole
Number of moles is given by :
n = m/M.M
n = 25.43/32 mole
n = 0.79 mole
Hence, this is the required solution.

A. Weathering
B. Deposition
C. Cooling
D. Uplift
The Sierra Nevada formed as a result of cooling processes.
What is an intrusive rock?
Intrusive rocks are one type of rocks that form under the surface or underground.
How do intrusive rocks form?The most common process for intrusive rock formation is through magma cooling and solidification. This implies the magma of a volcano loses temperature over time or it cools and this causes the material to harden forming a rock.
Over time these rocks might or might not move up the crust due to processes such as uplift as occurred with the Sierra Nevada.
