What is the boiling point of water at 1 atm in Kelvin

as we know ,

normal boiling point of water = 100° celcius

At a pressure of 1 ATM that is 100 kPa

boiling point will be 96.61°C

How many grams of O2 are required to precipitate all the iron in 75 mL of 0.090 M Fe2+?

Solnce55 [7]

mass O₂ required : 0.054 g

<h3>Further explanation </h3>

The reaction equation is the chemical formula of reagents and product substances

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products

Reaction

4Fe(OH)⁺ (aq) + 4OH⁻ (aq) + O₂ (g)+ 2H₂O (l)⇒ 4Fe(OH)₃ (s)

To precipitate Fe²⁺(in Fe(OH⁺) to Fe³⁺(in Fe(OH)₃)

mol Fe²⁺

$\tt 75\times 0.09=6.75~mlmol=6.75\times 10^{-3}mol$

mol ratio from equation = mol O₂ :mol Fe(OH) = 1 : 4

mol O₂

$\tt \dfrac{1}{4}\times 6.75\times 10^{-3}=1.6875\times 10^{-3}$

mass O₂

$\tt mass=mol\times MW\\\\mass=1.6875\times 10^{-3}\times 32=5.4\times 10^{-2}~g$

Carbon atom is tetravalent in nature. How many hydrogen atoms can bind to one carbon atom?

luda_lava [24]

<span>It is said that the carbon atom is a tetra valence which means, it contains 4 covalent bonds that can be bonded with other atoms. Therefore, it needs 4 hydrogen atoms to bind into 1 carbon atom. Carbon Atom contains a total of 6 electrons that occupies the 2 shells which is the K (have 2 electrons) and L (have 4 electrons) shells. The outermost shell of carbon atoms that contains 4 electrons is called as valence shell. In order to complete its octet, carbon Atom needs other atoms to share their valence electrons.</span>
