Answer:
Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
Explanation:
Answer:
The volumes are both, accurate and precise.
Explanation:
In the measurement of a set, precision refers to how much coincidence exists in the measurements of an specific value, as the measurements are close, we can say the volumes are precise.
Accuracy means the agreement that exists between the average of one
large series of measurements and the value of measurement
Media is 4,96 ml and I wanted to measure 5 ml. It is also close.
Answer:
Total amount of heat transfer, H_total = 115653.232 J/mol
Explanation:
Full explanation and step by step instructions is attached
We are going to use this formula:
Q = M*C*ΔT
when Q is the heat required
M is the mass of CCl4 = 10.35 g
C is the specific heat capacity of CCl4 = 0.874J/g.c
and ΔT the change in temperature = 56.4 - 32.1 °C =24.3 °C
∴ Q = 10.35g * 0.874 * 24.3 °C
= 219.8 J
