how do the prefixes of the –saccharide words relate to the structure of the sugar?

Answer:

I believe the answer is false

Explanation:

Earth's gravity comes from all of its mass. All the mass makes a combined gravitational pull on all the mass in an object. If you were on a planet with less mass than Earth, you would weigh less than you do here. Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Mass is not the gravitational pull on the earth.

Answer:

the addition of chlorine gas to a solution of potassium iodide.

The reaction that produces a colored substance is the addition of chlorine gas to a solution of potassium iodide. The correct option is D.

In a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.

Another sign that a chemical reaction has taken place is a change in color. If two solutions are combined and a color change occurs that is not just the effect of diluting one of the reactant solutions, a reaction has taken place. A solid and a liquid combined may also result in a change in color.

Therefore, the correct option is D. The addition of chlorine gas to a solution of potassium iodide.

Answer: Reaction Rate

Explanation:

reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Answer:

It's because it has 2 electrons on its outer ring

Explanation:

It has a -2 ion due to it having 2 more electrons than protons making it an overall negative. It's well known in chemistry that the first ring can only hold 2 electrons while the second and furthermore can hold up to 8. But what happens when you have 9? a new ring starts and it would only contain 1 electron.. In our case here it has 2 more electrons than protons and those 2 electrons are located on the outer ring

Explanation:

1.  H2O

Lewis Dot:  

See the attachment.

Note the б+ and б- signs on the H and O atoms, respectively.  Those represent the slightly positive and slightly negative sides of the water molecule.  Those slight charges on a single water molecule are attracted to their opposite charges on neighboring H2O molecules, as shown in the graphic.  This interaction is what gives water it's cohesive properties.

3.  The property of cohesion describes the ability of water molecules to be attracted to other water molecules. which allows water to be a "sticky" liquid.

The hydrogen bonds are attractions of electrostatic force.  They arise due to the difference in charge between the slightly positive hydrogen ion and the slightly negative oxygen ion. Hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond, and it is what gives water it's cohesiveness, or ability to support water spiders, paper clips, and produces a loud noise in the event of a belly flop in a pool (including the yelp from the swimmer).

4.  I'm not sure what is being asked for the two blanks.  Water is polar and dissolves salts (ionic compounds) and hydrophilic molecules (water-loving molecules).

There are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

The number of moles of nitrogen dioxide (NO2) in this question can be calculated by using the ideal gas law equation as follows:

PV = nRT

Where;

According to the reaction conditions given in this question;

2.46 × 4.8 = n × 0.0821 × 330

11.81 = 27.093n

n = 11.81 ÷ 27.093

n = 0.436mol

Therefore, there are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

The Atmosphere Is a separate layer And Also could be classified as the Closest layer

Explanation:

The downside of this is that the longer lasting material is more difficult to break down.

Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.

The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

1st question: A mixture is when the components of a mixture can be easily separated and that the components each keep their original properties.

2nd question:A phase is any part of a sample that has a uniform composition and properties.By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Heterogeneous mixtures are not uniform in composition. Examples would be wood or blood. Homogeneous mixtures are uniform through out. Typically you can see through them.

The free energy change of the reaction; Fe (s) + Au3+ (aq) -> Fe3+ (aq) + Au (s) is calculated to be -443.83KJ/mol.

For the reaction shown in question 7, we can divide it into half equations as follows;

Oxidation half equation;

6 Al (s) -------> 6Al^3+(aq) + 18e

Reduction half equation;

3Cr2O7^2-(aq) + 42H^+(aq)   + 18e -----> 6Cr^3+(aq) + 21H2O(l)

The balanced reaction equation is;

6Al(s) + 3Cr2O7^2-(aq) + 42H^+(aq)   -----> 6Al^3+(aq) + 6Cr^3+(aq) + 21H2O(l)

The E° of this reaction is obtained from;

E° anode = -0.04 V

E°cathode = +1.50 V

E° cell = +1.50 V - (-0.04 V) = 1.54 V

Given that;

ΔG° = -nFE°cell

n = 3, F = 96500, E°cell = 1.54 V

ΔG° = -(3 × 96500 × 1.54)

ΔG° = -443.83KJ/mol
