➷ The formula for Potassium oxide is K2O

This is because potassium has a 1+ charge and the oxygen has a 2- charge. Two potassium atoms are required to balance the charge.

The formula of Potassium oxide is K2O. It is in solid state. It contains two atoms of Potassium and one atom of Oxygen. It is basic in nature because it is a metal oxide. As we know that metal oxides are basic in nature. It turns red litmus paper into blue which proves that it is a basic in nature that is base.

The enthalpy change for the reaction of titanium metal with gaseous iodine is given by the following thermochemical equation: 2
julia-pushkina [17]

Answer : The enthalpy change for the reaction is, 419.5 kJ

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

The given chemical reaction is,

2Ti(s)+3I_2(g)\rightarrow 2TiI_3(s)    \Delta H=-839kJ

Now we have to determine the enthalpy change for the reaction below:

TiI_3(s)\rightarrow Ti(s)+\frac{3}{2}I_2(g)    \Delta H'=?

By reversing and then dividing the reaction by 2, we get the enthalpy change for the reaction.

The expression will be:

\Delta H'=-\frac{(\Delta H)}{2}

\Delta H'=-\frac{(-839kJ)}{2}

\Delta H'=419.5kJ

Therefore, the enthalpy change for the reaction is, 419.5 kJ

How many liters of hydrogen (at 0.97atm and 24c) will produce 180 grams of water
slava [35]

H₂ + ½O₂ → H₂O

2g → 18g

So, 18g water needs 2g H₂

So, 1g water needs 2/18g H₂

So, 180g water needs 2/18 x 180g H₂

→ 20 litres of H₂

If an atom has a mass number of 25 and an atomic number of 11 how many neutrons are there in this atom?
babunello [35]
C. 14
you would subtract the mass number from the protons or the atomic number because in order to find the mass number you would add the protons and neutrons :)
