You have a gas stored in a rigid container (fixed volume). Explain the relationship between a decrease in temperature, collision

s, and kinetic energy within the container.

Answer:

A decrease in temperature would decrease kinetic energy, therefore decreasing collisions possible.

Explanation:

A gas at a fixed volume is going to have collisions automatically. If you decrease the temperature (same thing as decreasing kinetic energy) you are cooling down the molecules in the container which gives them less energy and "relaxes" them. This decrease in energy causes them to move around much slower and causing less collisions, at a much slower rate. In a perfect world, these collisions do not slow down the molecule but we know that they do, just a very very small unmeasurable amount.

A monosaccharide is formed from a polysaccharide in what kind of reaction?.
Sever21 [200]

Answer:

Catabolic reactions

Explanation:

Anabolic reactions combine monosaccharides to form polysaccharides, fatty acids to form triglycerides, amino acids to form proteins, and nucleotides to form nucleic acids. These processes require energy in the form of ATP molecules generated by catabolic reactions.

If two atoms are bonded to a central atom with no lone pairs , how will they be arranged?
Dmitriy789 [7]
Most likely the geometric form of the molecule will be linear.
Explanation:
One possibility is the central atom being an atom with two valance electrons. This will create a liner molecule with no lone pairs of electrons
Another possibility is a central atom being an atom with four valance electrons. If the two atoms each require two bonds like oxygen the result will be a linear molecule with no lone pairs of electrons.

Which temperature is equal to 120. K?<br> (1) -153°C (3) +293°C<br> (2) -120.°C (4) +393°C
Marysya12 [62]
First of all, the formula for finding Kelvin is Celsius + 273
Therefore, if we subtract 273, we get the temperature in degrees
120 - 273 = - 153

Therefore, the answer is (1), or -153 degrees Celsius

Hope this helped!! :D

The rate of a reaction can be observed by measuring the change in the amount of a reactant over time, as given in the graph belo
Sveta_85 [38]

Looks like exponential decay. Collision theory is consistent with this model because at higher reactant concentrations we expect the reactants to encounter each other more often (collide) and as the concentration decreases we expect fewer and fewer collision events so the rate of reaction becomes less and less.

Why in a rollercoaster when the cart is going up it decreases the speed of the cart but when it's going down it increases?
alukav5142 [94]
Because gravity is trying to pull it down not up and when it's going down it's going with gravity not against it.
