Answer:
a = 12
b = 13
Explanation:
Consider the following equivalent expressions: 38÷1312 and 38?ab What are the values of a and b? Enter the value of a followed by the value of b, separated by a comma.
The solution is attached.
It is a covalant bond. Because any compound made up of nonmetals will be covalant. Compounds made up of a non metal and metal willl form a ionic compund. :)
Wait so we write the essay?
When red litmus turns blue, means the solution is basic, so it has more OH⁻ (hydroxide) ions.
The reaction, 2 C4H10 (g) + 13 O2 (g) = 8 CO2 (g) + 5 H2O (g), is the combustion of butane. A combustion reaction involves the reaction of a hydrocarbon with oxygen producing carbon dioxide and water. This reaction is exothermic which means it releases energy in the form of heat. Therefore, as the reaction proceeds,a heat energy is being given off by the reaction. This happens because the total kinetic energy of the reactants is greater than the total kinetic energy of the products. So, the excess energy should be given off somewhere which in this case is released as heat.
