<span>An iron fence is left on painted and it reacts with the oxygen in the air form forming rust. the formation of the rest is an oxidation-reduction reaction but it is also an example of a double-displacement reaction.
</span><span>cooking requires continuous addition of energy to the chemical reactions the are taking place the chemical reaction involved in cooking can be described as a chemical change.

Answer: A tropical year is longer than 12 lunar months and shorter than 13 of them. The arithmetical equation
12x12 + 7x13 = 235
allows it to be seen that a combination of 12 'shorter' (12 months) years and 7 'longer' (13 months) years will be equal to 19=12+7 solar years.
Explanation:
Electronic configuration of the atom describes the arrangemnet of electrons in different shells and subshells ( sublevels).
Now , there are 4 types of sublevels: s, p , d and f . These sublevels have orbital which are spaces with high probability of having an electron and each orbital can have maximum 2 electrons.
Therefore,
s-sublevel has 1 orbital - it can have maximum 2 electrons.
p-sublevel has 3 orbitals - it can have maximum 6 electrons
d-sublevel has 5 orbitals - it can have maximum 10 electrons
f-sublevel has 7 orbitals - it can have maximum 14 electrons.
Hence, the acsending order of sublevels in terms of maximum number of electrons is:
<h2>s < p < d < f</h2>
The temperature at which 75 grams ammonium bromide dissolve in 100g of water is 20 degree Celsius.
<h3>What is Solubility ?</h3>
Solubility can be defined as the maximum amount of solute that can be dissolved in a solution at a given temperature.
It is asked that
temperature at which 75 grams ammonium bromide dissolve in 100 g of water.
From the Solubility graph of Ammonium Bromide it can be seen that
at 20 degree Celsius , 75.5 g of Ammonium Bromide will get dissolved.
The temperature at which 75 grams ammonium bromide dissolve in 100g of water is 20 degree Celsius.
