<h3>Answer:</h3>

1 atom of sodium, 1 atom of oxygen and 1 atom of hydrogen

<h3>Explanation:</h3>

An atom is the smallest particle of an element that can take part in a chemical reaction.
Compounds and elements are made of atoms.
Atoms of the same element are similar while atoms making a compound are different as they are from different elements.
For example, Cl₂ is an element made up of two chlorine atoms, while NaOH is a compound made up of atoms of different elements. That is, one sodium atom, one oxygen atom and one hydrogen atom.

A certain gas at 2oC and 1.00 atm pressure fills a 4.0 container. What volume will the gas occupy at 100oC and 780 torr pressure

artcher [175]

The final volume V₂=4.962 L

<h3>Further explanation</h3>

Given

T₁=20 + 273 = 293 K

P₁= 1 atm

V₁ = 4 L

T₂=100+273 = 373 K

P₂=780 torr=1,02632 atm

Required

The final volume

Solution

Combined gas law :

P₁V₁/T₁=P₂V₂/T₂

Input the value :

V₂=(P₁V₁T₂)/(P₂T₁)

V₂=(1 x 4 x 373)/(1.02632 x 293)

V₂=4.962 L

Calculate hydrochloric acid (umol)in 200 ul of a<br> 0.5173Msolution of acid?

strojnjashka [21]

<u>Answer:</u> The moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

Or,

$\text{Molarity of the solution}=\frac{\text{Micro moles of solute}\times 10^6}{\text{Volume of solution (in }\mu L)}}$

We are given:

Molarity of solution = 0.5173 M

Volume of solution = $200\mu L$

Putting values in above equation, we get:

$0.5173M=\frac{\text{Micro moles of HCl}\times 10^6}{200\mu L}\\\\\text{Micro moles of HCl}=1.0346\times 10^{-4}\mu mol$

Hence, the moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$
