Which part of the flame should be touching the bottom of a beaker if you want to heat its contents rapidly

1 answer:

4 0

Given what we know, we can confirm that in order to heat the contents in the most rapid fashion, the bottom of the beaker should be just barely touching the tip of the flame.

<h3>Why is this the optimal position for the flame?</h3>

As we know, heat will rise.
This means that all of the heat energy generated by the flame will move upwards.
By placing the beaker just above the tip of the flame, we ensure that all of the energy is deposited onto the beaker and its contents.

Therefore, due to the fact that the heat generated by the flame will rise, placing the beaker just above the tip of the flame will ensure that all of the heat generated by the flame will be deposited onto the contents of the beaker, heating it rapidly.

What is the energy required to remove the electron from a hydrogen atom in the n = 11 state?

zaharov [31]

Based on the data given, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV

<h3>What is ionization energy?</h3>

Ionization energy is the energy requiredto remove an electron from a neutral atom or a cation in its gaseous state.

To calculate the energy required to remove the electron from a hydrogen atom in the n = 11 state, the formula below is used:

$E_n = \frac{E_0 × Z^{2}}{n^{2}}$

where

$E_0 \: is \: ground \: state \: energy \: of \: hydrogen \: atom \: = -13.6 eV \\$

Z = 1
n = 11

substituting the values:

$E_n = \frac{ - 13.6 × 1^{2}}{11^{2}} \: = - 0.112 \: eV$

Therefore, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV

Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction while Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells,in an electrolytic cell, the cathode is negatively charged and the anode is positively charged

Very easy significant figures question!

Anon25 [30]

As you said, the answer is 150.

But in all the numbers, there's a comma with two zeros, and so you have to put them in your answer : 150,00

They are the significative numbers.

Hope it helps
