Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question we have

$V_2 = \frac{207000 \times 0.05}{101000} = \frac{10350}{101000} \\ = 0.102475...$

We have the final answer as

Hope this helps you

In an aqueous solution of a certain acid the acid is 4.4% dissociated and the pH is 3.03. Calculate the acid dissociation consta

NeX [460]

Answer:

4.1x10⁻⁵

Explanation:

The dissociation of an acid is a reversible reaction, and, because of that, it has an equilibrium constant, Ka. For a generic acid (HA), the dissociation happens by:

HA ⇄ H⁺ + A⁻

So, if x moles of the acid dissociates, x moles of H⁺ and x moles of A⁻ is formed. the percent of dissociation of the acid is:

% = (dissociated/total)*100%

4.4% = (x/[HA])*100%

But x = [A⁻], so:

[A⁻]/[HA] = 0.044

The pH of the acid can be calcualted by the Handersson-Halsebach equation:

pH = pKa + log[A⁻]/[HA]

3.03 = pKa + log 0.044

pKa = 3.03 - log 0.044

pKa = 4.39

pKa = -logKa

logKa = -pKa

Ka = $10^{-pKa}$

Ka = $10^{-4.39}$

Ka = 4.1x10⁻⁵

How many moles would contain 1.50 x 1024 atoms of sodium?

riadik2000 [5.3K]

<h3>Answer:</h3>

2.5 moles

<h3>Explanation:</h3>

<u>We are given;</u>

1.5 × 10^24 atoms

We are required to determine the number of moles of sodium.

We know that, 1 mole of an element contains a number of atoms equivalent to the Avogadro's number, 6.022 × 10^23.
That is, 1 mole of an element = 6.022 × 10^23 atoms.

Therefore;

1 mole of sodium contains 6.022 × 10^23 atoms

To get the number of moles;

= Number of atoms ÷ Avogadro's number

= 1.5 × 10^24 atoms ÷ 6.022 × 10^23 atoms/mol

= 2.49 moles

= 2.5 moles

Therefore, 2.5 moles of sodium contains 1.50 × 10^24 sodium atoms

Which type of bond is found between atoms and solid cobalt?

zheka24 [161]

Cobalt is a metal thus the atoms are bonded together in giant atomic structures and metallic bonds. The atoms attract each other with very strong atomic forces this the resulting structure is giant atomic structures. This provides for the extra strong structure of cobalt.
