All matter consists of atoms, which, in turn, consist of protons, neutrons and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged. Electrons are negatively charged, a...
What is the formula for calculating enthalpy? Calculate the standard enthalpy change for each of the following: a) 2NH3(g) + 3/2 O2 (g) = N2(g) + 3H2O(g) b) 2NO(g) + O2(g) = 2NO2(g) c) H2SO4(I) = SO2(g) + H2O (g) + 1/2 O2...
Calorimetry is defined as the science that deals with the phenomenon that takes place due to the heat transfer and calorimetry measure the heat change via a system and checks whether the net heat releases or get absorbed in the system.
To solve the problem of determining the energy, momentum, and wavelength of the photon emitted when a hydrogen atom transitions from the n=3 state to the n=1 state, we will follow these steps:Step 1: Calculate the Energy of the Photon E

THE WOUND PROFILE - UNDERSTANDING THE PROJECTILE-TISSUE INTERACTION A projectile crushes the tissue it strikes during penetration, and it may impel the surrounding tissue outward (centrifugally) away from the missile path. Tissue crush is responsible for what is commonly called the permanent ...
A) How much momentum does the photon carry off? B) How much kinetic energy does the hydrogen atom acquire? Is this energy needed to be taken into account while determining the energy of the emitted photon? Why or why not? What is the frequency of a photon that has the same momentum as...
How much heat (in Joules) is gained by the water where a chemical reaction takes place in 100 mL aqueous solution and has a temperature increase of 13 degrees C? Hint: ignore any effects by the calorimeter. A calorimeter with a heat capacity of 4.61 kJ/K co...
What are the units for 5? 2? 3?Dimensional Analysis:Dimensional analysis is the method of determining the units of unknown physical quantities from the units of known physical quantities. When two physical quantities are added or subtracted, their dimensions remain the same. When two or ...
