Alja [10]

Answer:

C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat

Explanation:

There are 6 carbon atoms in reactants to balance you put coefficient 6.

This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.

There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.

If u recheck: 6 C atoms in reactants, 6 C atoms in products.

10 H atoms in reactants, 10 H atoms in products.

17 O atoms in reactants, 17 O atoms in products.

The Earth and the spaceship both have mass. The astronaut is attracted to Earth by gravity, but he is not attracted to the space

Shkiper50 [21]

The spaceship does not have any gravitational pull. A spaceship can not produce its own gravity like Earth does.

6)Explain why a 0.010 M solution of hydrochloric acid, HCl has a pH of 2.00 but a 0.010 M solution of

ExtremeBDS [4]

0.010 M solution of hydrochloric acid, HCl has a pH of 2.00 but a 0.010 M solution of acetic acid, HCH₃COO, is 3.37 is because HCl dissociates more.

<h3>Dissociation</h3>

This is the separation of ions of an ionic compound when it dissolves.

<h3>Hydrogen ion concentration of HCl</h3>

Since 0.010 M solution of hydrochloric acid, HCl has a pH of 2.00 its hydrogen ion concentration is gotten from

pH = -log[H⁺]

So,

$[H^{+} ] = 10^{-pH}$

So, [H⁺] = 10⁻²

<h3>Hydrogen ion concentration of HCH₃COO</h3>

Also, since 0.010 M solution of acetic acid, HCH₃COO, has a pH of 3.37, its hydrogen ion concentration is gotten from

pH = -log[H⁺]

So,

$[H^{+} ] = 10^{-pH}$

So, [H⁺] = 10⁻³°³⁷ = 0.000427 = 4.27 × 10⁻⁴

Since the hydrogen ion concentration of HCl is 10⁻² and the hydrogen ion concentration of HCH₃COO is 4.27 × 10⁻⁴, we see that HCl dissociates more than HCH₃COO.

So, 0.010 M solution of hydrochloric acid, HCl has a pH of 2.00 but a 0.010 M solution of acetic acid, HCH₃COO, is 3.37 is because HCl dissociates more.
