Protons: <span>The mass of the proton is about 1,840 times the mass of the electron and slightly less than the mass of the neutron.
Electrons: </span><span>Electrons are arranged around the nucleus of atoms in regions called electron clouds or electron orbits.
Neutrons: </span><span>A neutron is one of two particles found inside the nucleus (central part) of an atom. The other particle is called a proton. Electrons are particles that move around an atom outside the nucleus.</span>
There are 12 inches in a foot and 36 inches in a yard. SO your answer is 900 inches
Answer:The empirical formula is KCO2
Explanation:
The H3O+ concentration of the solution with a PH of 3.60 is 2.5 x10^-4 M (answer A)
<u><em>explanation</em></u>
PH is calculated using PH = - log [ H3O+] formula
Therefore - log [H3O+] = 3.60
To calculate the concentration of h3O+ ,find the antilog of 3.60
Since -log is at base of 10, the antilog of 3.60 = 10^-3.60 = 2.5 x10^-4M
Use the ideal gas equation PV=nRT. You can compare before and after using P1V1/n1T1=P2V2/n2T2. Since the number of moles remains constant you can disregard moles from the equation and use pressure, volume and temp. Make sure your pressure is converted to atmospheres, your volume is in liters, and your temperature is in kelvins.
