Answer:

4.3moles contains 2.08×10(to the power of)24 atoms.

the relationship between atoms and moles

1mole atoms=6.022×10(to the power of)23

4.3mol×6.022×10

Through what process do all stars produce their energy?

Deffense [45]

nuclear fusion

Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the "proton-proton chain," a sequence of events that transforms four hydrogen atoms into one helium atom.

Calculate the number of atoms of carbon present in 25 g of CACO3 ?

stiks02 [169]

1.506 × 10²³ carbon atoms

Explanation:

First we calculate the number of moles of calcium carbonate (CaCO₃) contained in 25 g.

number of moles = mass / molecular weight

number of moles of CaCO₃ = 25 / 100 = 0.25 moles

Now we make use of Avogadro's number which tell us that we have 6.022 × 10²³ molecules (or atoms) in one mole of substance.

Now in our case:

if in 1 mole of CaCO₃ we have 1 × 6.022 × 10²³ carbon atoms

then in 0.25 moles of CaCO₃ we have X carbon atoms

X = (0.25 × 1 × 6.022 × 10²³) / 1

X = 1.506 × 10²³ carbon atoms

Hydrogen sulfate reacts with water to produce sulfate ions and hydronium ions: hso4−+h2o⇌so42−+h3o+ identify the conjugate acid-

Angelina_Jolie [31]

The generic equation for a reaction between an acid and water is

$HX_{(aq)} + H_{2}O_{(aq)} --> X_{(aq)}^{-} + H_{3}O_{(aq)}^+$

When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base ( $X^-$ ), and the conjugate acid-base pair is $HX$ - $X^-$ .

Hydrogen sulfate ( $HSO_{4}^-$ ) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water (( $H_{2}O$ ) to form the sulfate ( $SO_{4}^2-$ ) and hydronium ( $H_{3}O^+$ )ions.

$HSO_{4(aq)}^{-} + H_{2}O_{(aq)} --> SO_{4(aq)}^{2-} + H_{3}O_{(aq)}^+$

Based on the previous discussion, $SO_{4(aq)}^2-$ is identified to be the conjugate of the acid $HSO_{4(aq)}^-$ . Thus, the conjugate acid-base pair is $HSO_{4(aq)}^{-} - SO_{4(aq)}^{2-}$ .
