How many moles of h2o would be produced from 1.75 moles of o2 with unlimited c3h6

Answers

Answer 1

Answer: 1.75 (moles O2) × 6 (moles H2O) ÷ 9 (moles O2) = 1.17 (moles H2O)

You have to convert moles of O2 into moles of H2O so it's the number of moles you start with (1.75 O2) × the number of moles from the element you want (6 H20), then ÷ by the number of moles that the element that you already have (9 O2).

Well, you could get the mass as $m=(G_0)/(g_0)$ ad then $g_1=(G_1)/(m)$ , where $G_0$ is the sea level weight, $g_0$ the sea level accel., $g_1$ the accel. above while $G_1$ the weight above.

Explanation:

The density of a liquid form of a material is always less than the density of the solid form of that same material true or false

Answers

Answer:

False

Explanation:

This property depends on the intermolecular interactions of the analyzed compound.

In most cases, this property is fulfilled, but one of the most important exceptions is water since ice cubes float in liquid water which means that its density is lower than that of liquid water.

This is due to one of the types of bonds that binds hydrogen bonds to water molecules.

Hydrogen bridges are a molecular interaction that occurs between the hydrogen in one molecule of water and the oxygen in another molecule.

Recall the formula of the density

$d=(m)/(v)$

The volume is inversely proportional to the density this means that the lower the volume the higher the density and the higher the volume the lower the density.

This type of bonding means that when the $H_2O$ freezes there is more space between the molecules, then they occupy a larger volume

Therefore, if we have the same mass in the liquid state and the solid-state, the molecules in the liquid state will be closer together occupying less volume (higher density) and the molecules that are in the solid-state occupy a greater volume (lower density)

Almost always true. H2O is the exception as water is more dense than ice.

In the second century BCE, the Greek astronomer Ptolemy tried to explain the backward movement of the planets by using a solar system model that included epicycles. For centuries, this was the accepted model. During the Renaissance, Nicholas Copernicus discovered the old heliocentric model of Aristarchus. In Aristarchus’s model, the rising and setting of the Sun was explained by the movement of the Earth.

What is Heliocentric Model?

The heliocentric theory of the Solar System (aka, the heliocentric model) is a theory that places the Sun at the center of the Solar System. It also maintains that the Earth revolves around the Sun.

This theory was first proposed by Nicolaus Copernicus.

Copernicus was the first to propose a theory which differed from Ptolemy's Geocentric System, according to which the earth is at rest in the center with the rest of the planets revolving around it. The claim that all planets revolve around the sun had been raised in ancient times, but Copernicus was the first to succeed in describing the movements of the planets using an astronomical theory which placed the sun at the center.
