What else can I help you with?
If you need to reverse the following reaction and multiply it by 2 in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you?
If you need to reverse a reaction and multiply it by 2 in Hess's law, the enthalpy change of the reaction will also change sign and double in magnitude. This is because reversing a reaction changes the sign of the enthalpy change. Multiplying the reaction by a factor also multiplies the enthalpy change by that factor. Therefore, the final value for the enthalpy of the reaction will be twice the original magnitude but with the opposite sign.
Can you provide some bond enthalpy practice problems for me to work on?
Here are some bond enthalpy practice problems for you to work on: Calculate the total bond enthalpy of a molecule of methane (CH4) given the bond enthalpies of C-H and C-C bonds. Determine the bond enthalpy of a nitrogen-nitrogen (NN) triple bond using the bond enthalpies of N-N single and double bonds. Calculate the bond enthalpy of a molecule of water (H2O) using the bond enthalpies of O-H bonds. These problems will help you practice calculating bond enthalpies and understanding the energy required to break or form chemical bonds.
Does doubling the concentrations of acid and base in a neutralization reaction double the amount of heat released?
No, doubling the concentrations of acid and base in a neutralization reaction does not necessarily double the amount of heat released. The heat released in a neutralization reaction depends on the specific stoichiometry and enthalpy of reaction, which may not be directly proportional to concentration changes.
Why is benzene not considered a cycloalkene?
First of all a cycloalkene could be many things, such as, cyclopentane, cyclohexane or like. If you mean the difference between cyclohexene and benzene, then there is the double bound, 3 of a kind in a benzene molecule.
Would this reaction happen NaCl plus CaF2 - NaF plus CaCl2?
The reaction is2NaCl + CaF2 --> 2NaF + CaCl2and the enthalpies of formation (kJ/Mol) of the solids at STP are2NaCl = (-411)*2CaF2 = -1220Total = -20422NaF = (-469)*2CaCl2 = -796Total = -1734The calculations show that the reactants are more stable than the products by some 307kJ/mol, so that the reaction would not proceed. (For more advanced readers, the value for the Gibbs free energy of formation will not be very much different from this, as the entropy terms will be relatively small in comparison with the enthalpy terms.) A major factor in this is the relatively high lattice enthalpy of CaF2.

How many tons does a double garage weigh?
The weight of a double garage can vary depending on its size, materials used, and construction methods. On average, a double garage could weigh anywhere from 5 to 10 tons. It is best to consult with a structural engineer or contractor for a more accurate estimate based on specific details of the garage.
How do you estimate to check?
You round and double check to see if its right are not.
When did they start making side by side double barrels to estimate a year?

How do you give average command in a calculator in visual basic?
There is no average command in VB. You would have to write your own method for that. I would write it like this Public double getAverage() { double average; average = totalAdded/ totalNumbers; return average; } You would have to have totalAdded and totalNumbers as an instance variable.
What is the average weight of a double bunk bed?
700000lbs
How do you Calculate the average of two numbers then return the average in c plus plus?
Use the following function: /* returns the average of two real numbers */ double average (const double a, const double b) { return a/2.0 + b/2.0; } Note that we do not use (a+b) / 2.0 because the expression a+b could overflow the range of a double. By dividing each value by 2 before summing we ensure the result can never overflow no matter how large a and b are. Ideally, you should write separate functions to cater for float and long double arguments independently: /* returns the average of two long doubles */ long double average_lng (const long double a, const long double b) { return a/2.0 + b/2.0; } /* returns the average of two floats */ float average_flt (const float a, const float b) { return a/2.0F + b/2.0F; } For mixed-mode arithmetic, always use the highest precision argument. E.g., the average of a float and a double is a double, so use the function that returns a double, not a float. The float argument will be implicitly cast to a double.
How do you write c program of moving average?
double movingaverage (double raw, double smoothed, double alpha) {return smoothed / (1.-alpha) + raw/alpha;}
