Explanation:
A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.
Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.
This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.
The information regarding the different carbohydrates that should be formed is explained below.
Carbohydrates:It should be created from carbon, hydrogen, and oxygen. It should be combined with every carbohydrate. Still, carbohydrates should be comprised of only these three atoms, so the no of atoms of these elements in every carbohydrate also the spatial arrangement of these atoms in every carbohydrate is not similar.
This represents that various carbohydrates contain distinct numbers of carbon, oxygen, and hydrogen atoms that are in different ways in space.

What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

What is the average speed of 3043 km from houston to seattle in 5.5 hours rounded to the nearest hundredth
Answer:
The average speed is 553.27[tex]\frac{km}{hour}[/tex]
Explanation:
Speed is the physical magnitude that shows and expresses the variation in position of an object and as a function of time. In other words, the speed relates the distance traveled by an object in the unit of time.
The average speed is the quotient of the space traveled by an object and the time it takes to cover the path:
[tex]speed=\frac{distance}{time}[/tex]
In this case:
distance: 3,043 kmtime: 5.5 hoursSo, replacing in the definition of speed:
[tex]speed=\frac{3,043 km}{5.5 hours}[/tex]
Solving:
speed= 553.27[tex]\frac{km}{hour}[/tex]
The average speed is 553.27[tex]\frac{km}{hour}[/tex]

1. What is the volume
occupied by 20.4 liters of
CO2 at 1200 Torr when it is
at STP
Answer:
Explanation:
From your question you’ll have to assumethat the temperature is constant,since you do not have an initial temperature.
If thats the case thrn you can use;
P1V1=P2V2 to calculate the second volume.
P1=1200 torr
P2=760 torr
V1 = 20.4L
The volume occupied by 20.4 liters of Carbon dioxide (CO₂) at 1200 Torr when it is at Standard temperature pressure is 32.21 L.
How we calculate the volume?Volume of gas can be calculated by arranging the ideal gas equation as:
P₁V₁ = P₂V₂, where
P₁ = given pressure = 1200 Torr
V₁ = given volume = 20.4 L
P₂ = standard pressure = 760 Torr
V₂ = to find?
Here, we consider the moles and temperature of gas is constant, on putting all these value on the above equation we get:
V₂ = (1200 × 20.4) / 760 = 32.21 L
Hence, 32.21 L is the required volume.
