What is the value of the activation energy of the uncatalyzed reaction? Express your answer to three significant figures and inc
goblinko [34]

Answer:

175 kJ

Explanation:

Activation energy can be defined as the potential energy that is needed to change reactants to products. This is the minimum energy required for the chemical reaction to take place. Thus, using the given figure:

Activation energy = activation complex - reactant energy

In the given figure, activation complex = 400 kJ

reactant energy = 225 kJ

Therefore:

Activation energy = 400 - 225 = 175 kJ

Is this the correct procedure for cleaning volumetric glassware prior to making a measurement: first, rinse with tap water. Seco
Bogdan [553]

The steps to be followed while cleaning volumetric glassware are:

1. Remnants from the previous measurements are wiped off with the help of paper towel.

2. The glassware is then soaked overnight in warm soap solution.

3. Then before rinsing with tap water, the glassware are scrubbed with an appropriate brush.

4. After scrubbing, the glassware is rinsed thoroughly with tap water in order to make sure there are no traces of soap solution.

5. The glassware is then rinsed with de-ionized water and finally with the solution that would be used for the volumetric measurement.

Electromagnetic waves with the shortest wavelengths and highest frequencies are called​
Feliz [49]

Gamma rays

Explanation:

Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.

The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.

  • Gamma rays also are the most energetic electromagnetic radiation.
  • The short wavelength of gamma rays suggests that more waves passes with times.
  • It's high frequency shows that a high amount of wave passes through a point at each passing of time.
  • These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
  • Gamma rays are ionizing radiations which causes ionization of gas molecules.

Someone please help me:
Stels [109]

Answer: The number to the left of AC should be 6.

Explanation: The balanced chemical reaction is one in which the number of atoms  of each element on the reactant side must be equal to the number of atoms on product side.

The given equation A_2B + DC_3 \rightarrow AC + D_2B_3 is unbalanced as the atoms on the reactant side are not same as number of  atoms on product side. This equation is called as skeletal equation.

The balanced chemical equation is :

3A_2B + 2DC_3 \rightarrow 6AC + D_2B_3

Thus the number to the left of AC is 6.
