Al examinar una mezcla de reactivos utilizando papel tornasol rojo, se obtiene una coloración azul indicativa de presencia de hidróxidos, el óxido que reaccionó con agua para cambiar la coloración del papel tornasol fue

Well, considering that the test strip when putting it in the color change solution, we consider that these test strips usually change color when the other substance is BASIC.

They usually change their color to blue

Explanation:

In the event that these test strips are contacted with an acidic solution, these strips will not change color, and will maintain their pink / fuchsia color.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
