- According to collision theory, what is not a factor that determines if two molecules will bind?
Natali5045456 [20]

The factor which will not determines if two molecules will bind according to collision theory is the direction the molecules are facing

<h3>What is collision theory?</h3>

Collision theory is a theory which describes of predicting the rate at which chemical reactions occurs between atoms and molecules of elements.

So therefore, the factor which will not determines if two molecules will bind according to collision theory is the direction the molecules are facing

Calculate the standard molar enthalpy for the complete combustion of liquid ethanol (c2h5oh) using the standard enthalpies of fo
olga2289 [7]
Answer : To calculate the standard molar enthalpy of complete combustion of liquid ethanol can be done by using the formula given below;

C_{2}  H_{5}OH + 3O_{2} ----\ \textgreater \   2CO_{2}  + 3 H_{2}O

Now, the enthalpies of the elements in their standard state is zero always. 

So the H_{reaction} =  H_{products}  - H_{reactants}

Here we can avoid the heat of enthalpy of oxygen,carbon dioxide and water as they exists in their standard states.

So the H_{reaction} = H_{ C_{2}H_{5}OH}

How many molecules are there in 31.8 moles of water?
Murljashka [212]

Answer:

31.8\ moles = 1.91 * 10^{25}\ molecules

Explanation:

Given

31.8 moles of water

Required

Determine the number of molecule

In standard units: 1 molecule of water is:

1\ mole = 6.022 * 10^{23}\ molecules

Multiply both sides by 31.8

31.8 * 1\ mole = 31.8 *  6.022 * 10^{23}\ molecules

31.8\ moles = 31.8 *  6.022 * 10^{23}\ molecules

31.8\ moles = 191.4996 * 10^{23}\ molecules

Express 191.4996 as a standard form

31.8\ moles = 1.914996 * 10^2 * 10^{23}\ molecules

Apply law of indices:

31.8\ moles = 1.914996 * 10^{2+23}\ molecules

31.8\ moles = 1.914996 * 10^{25}\ molecules

Approximate:

31.8\ moles = 1.91 * 10^{25}\ molecules
