Increasing the temperature of reactants that undergo an endothermic reaction will shift equilibrium towards product side, leading to an increase in concentration of products and decrease in concentration of reactants. This effect can be explained by Le Chatelier's principle
Increasing the temperature of reactants that undergo an endothermic reaction will shift the equilibrium position towards the product side of the reaction.
This is because an endothermic reaction absorbs heat from the surroundings, and increasing the temperature provides the reaction with more heat, which can be used to drive the reaction in the forward direction. The effect of temperature on the equilibrium position of a reaction can be understood using Le Chatelier's principle.
According to Le Chatelier's principle, when a system at equilibrium is subjected to a change in temperature, pressure, or concentration of reactants or products, the system will shift its equilibrium position in a way that tends to counteract the change. In the case of an endothermic reaction, increasing the temperature is a change that is counteracted by the reaction absorbing more heat.
To understand this effect more quantitatively, we can consider the equilibrium constant, Kc, which is defined as the ratio of the product concentrations to the reactant concentrations at equilibrium. For an endothermic reaction, the equilibrium constant is given by: Kc = [products]/[reactants]
As the temperature is increased, the value of Kc remains constant, but the concentrations of the reactants and products change. Since the reaction absorbs heat, the equilibrium position will shift towards the product side, leading to an increase in the concentration of products and a decrease in the concentration of reactants.
This will result in an increase in the value of the equilibrium constant, indicating that the reaction is proceeding in the forward direction.

Collision of which two types of plates create the deepest earthquakes? Why do you think this is?
Answer:
The collision of oceanic plates and any other plates in which the oceanic plate slides beneath the other plate creates the biggest earth quakes. Most of these earth quakes occur beneath the sea or oceans and can cause volcanic eruptions as well. Tsunami is another oceanic event that occurs due to earth quakes occurring due to shifting of plates beneath the sea.
Oxygen has 8 positively charged protons what is the number of negatively charged electrons in an atom of oxygen?
Answer:
8 electrons (e-)
Explanation:
In the atom of every elements, there are three sub-atomic particles namely: protons, electrons, and neutrons. The protons are the positively charged particles, the electrons are negatively charged while the neutrons are neutrally charged.
In an uncharged or neutral atom i.e. charge 0, the number of protons is always equal to the number of electrons because they cancel each other out. When a difference occurs in the number of these particles, the atom becomes charged i.e. an ion. According to this question, oxygen atom (O) contains 8 positively charged protons, this means that it also contains 8 negatively charged electrons in its atom.
If 3.68 grams of zinc were allowed to react with excess hydrochloric acid to produce zinc chloride and hydrogen gas, how much zinc chloride should be produced?
Suppose that 7.12 grams of zinc chloride is actually recovered, what is the per cent yield?
Answer:
Here... Since there is excess HCl, you know the Zinc will be the limiting reagent. I was able to create the reaction equation based on the info you gave: Z + 2HCl ----> ZCl2 +2H. Now, in order to find the theoretical yield of ZCl, you need to convert Zinc from grams to moles. Do this by dividing by its molar mass (65.38), thus: 3.68 (g) / 65.38 (g/mol) = 0.056286... moles.
Now, using the balanced equation we made earlier, we see that 1 mole of Zinc creates 1 mole of ZCl2. Thus our ratio is 1:1. This makes the next step easy. Since it is 1:1, we multiply the number of moles we have of Zinc (0.056286...) by the number of moles it will create of ZCl (1). (0.056286)(1) = 0.056286 moles ZCl. Now convert this to grams by multiplying by its molar mass (136.28) and you get 7.67 grams. This is your theoretical yield. The percent yield is found by dividing the actual amount obtained (7.12 g.) by the theoretical yield (7.67 g.) then multiply that by 100%. When this is done, your Percent Yield is about 92.8%

How many atoms are in 2.54 mole O?
Answer: 1.505 * 10^24 atoms
========================================================
Work Shown:
1 mole = 6.02 * 10^23 atoms
2.5*(1 mole) = 2.5*(6.02 * 10^23 atoms)
2.5 moles = (2.5*6.02) * 10^23 atoms
2.5 moles = (15.05) * 10^23 atoms
2.5 moles = (1.505 * 10^1) * 10^23 atoms
2.5 moles = 1.505 * (10^1*10^23) atoms
2.5 moles = 1.505 * 10^(1+23) atoms
2.5 moles = 1.505 * 10^24 atoms
This is true for any element. This value is an approximation since there are roughly 6.02 * 10^23 atoms in 1 mole of any element.

Given the following equation: Na2O + H20 - 2 NaOH
How many grams of Na20 are required to produce 1.60 x 102
grams of NaOH?
g
Answer:
124g
Explanation:
The concept stoichiometry is used here to determine the mass of Na₂O. The grams of Na₂O required to produce 1.60 x 10² grams of NaOH is 124 g.
What is Stoichiometry?The stoichiometry is an important concept of chemistry which help us to use the balanced chemical equation to calculate the amounts of reactants and products. The stoichiometric coefficient is the number of molecules that can participate in the reaction.
The balanced equation is:
Na₂O + H₂O → 2NaOH
1 mole of Na₂O is required to react with 1 mole of H₂O to give 2 moles of NaOH.
62 g of Na₂O produces 80 g of NaOH.
1 g of NaOH is produced from 62/80 g of Na₂O .
1.6 × 10² g of NaOH will require 62 × 1.6 × 10² g / 80 g of Na₂O = 124 g Na₂O
Thus the grams of Na₂O required to produce 1.6 × 10² g of NaOH is 124 g.

Each element... A. Has only one kind of atom B. Has only one kind of molecule C. Is made of rock D. All of the above
Answer:
A. Has only one kind of atom
Explanation:
All forms of matter are composed of elements.
An element is a substance which cannot be broken down into simpler units or converted into other substances by ordinary chemical reactions. Each element is composed of only one kind of atoms which are unique to each element. There are three fundamental sub-particles present in atoms of elements; these are: protons, electrons and neutrons. An atom of an element differs from an atom of another element by its atomic number. The atomic number of an element is the number of protons present in the nucleus of the atom of that element. For example, hydrogen atoms has an atomic number of 1, while sodium atoms has an atomic umber of 11.
Atoms of the same element or different elements may combine together to form the molecules of a substance. For example, a molecule of hydrogen gas is made up of two atoms of hydrogen whereas a molecule of water is composed of two atoms of hydrogen and an atom of oxygen.
Elements can exist in any of the three physical states: solids, liquids or gases. For example, hydrogen exists as gas, mercury as a liquid, while gold exists as a solid.
is there a relationship between the relative age of stars in the number/identity of element is found within them
Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.
