The correct answer to this question is A, T2=∆T1. Temperature changes are one of many ways an indication of a chemical change is occurring. Other signs include a change in color, an odor, and bubbles forming. These changes aren't able to be seen but can be felt.
An example is putting a...Read More
The answer to this question is A. This is a type of limiting reactant problem wherein the acid is in deficiency. Half of the dihydrogen will evolve depending on the amount that will be placed. To determine the moles of magnesium, you need to divide the given mass by the molar mass.
You al...Read More
An equilibrium in science refers to the elements on all side of the situation are balanced. One element doesn’t overpower another item. They are all balanced and the same. There are times that a mixture of ice and water can reach an equilibrium.
There are certain actions that must b...Read More
It is not true to say the one mole of hydrogen gas contains 6.02x 10^23 atoms of hydrogen. However, some true statements that involve hydrogen would be that one molecule of methane contains four moles of hydrogen atoms, one mole of carbon 12 has a mass of 12.00g, and one mole of methane...Read More
Bonds are made of energy. There are certain energy changes that occur during the making or breaking of bonds and this is called enthalpy changes. When a bod is broke, energy is required to break the bond, hence energy is taken in or absorbed when bonds are broken. This makes bond breaking an...Read More
For those uninitiated to chemistry (like me), enthalpy is just the amount of heat that is given off in a specific chemical reaction. If a typical carbon-hydrogen bond gives off 412 kilojoules per molecule, then you have to find the equation that gives carbon and hydrogen in equal proportions...Read More
Correct answer option C - the amount of reactants and product do not change is always true for a chemical reaction that has reached equilibrium.
Chemical reaction at equilibrium occurs when reactants and products are present in a concentration and have no further tendency to change with t...Read More
The answer to this is A. For those who are not familiar with what ammonium nitrate is, this is a type of chemical compound that is used in order to fertilize different plants and crops. People who work in the agricultural setting are familiar with this compound especially since it is in solid...Read More
