The boiling point of plain water is less than the boiling point of both salt and sugar water.
<h3>What is boiling point?</h3>
Boiling point can be defined as the point when the pressure exerted by the surroundings upon a liquid is equal to the pressure exerted by the vapour of the liquid.
The boiling point of plain water is 100°C which increases upon addition of solute substances such as salt and sugar.
But salts are usually made up of ionic bonds while sugar are made up of covalent bonds. This means that more energy would be required to boil salt solution due to its ionic bonds.
Therefore, the boiling point of salt water is highest following sugar water before plain water which is the lowest.

Explanation:
Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.
En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano
Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.
Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.

Answer:Explanation:Protons and other subatomic particles will be discussed a little later. The atoms of different elements are different from each other because they have different numbers of protons. The graphic below illustrates this point by showing the atoms of two elements in the containers of oxygen and hydrogen.
You must burn 1.17 g C to obtain 2.21 L CO₂ at STP.
The balanced chemical equation is
C + O₂ → CO₂.
<em>Step 1</em>. Convert <em>litres of CO₂ to moles of CO₂</em>.
STP is <em>0 °C and 1 bar</em>. At STP the volume of 1 mol of an ideal gas is 22.71 L.
Moles of CO₂ = 2.21 L CO₂ × (1 mol CO₂/22.71 L CO₂) = 0.097 31 mol CO₂
<em>Step 2</em>. Use the molar ratio of C:CO₂ to <em>convert moles of CO₂ to moles of C
</em>
Moles of C = 0.097 31mol CO₂ × (1 mol C/1 mol CO₂) = 0.097 31mol C
<em>Step 3</em>. Use the molar mass of C to <em>calculate the mass of C
</em>
Mass of C = 0.097 31mol C × (12.01 g C/1 mol C) = 1.17 g C
It looks as if you are using the <em>old (pre-1982) definition</em> of STP. That definition gives a value of 1.18 g C.
