it must be a eukaryote because prokaryotic dna floats inside of it.
{ 12 mol * 27 g / mol * 0.902 j/gdeg C* ( 658 -72 ) deg C + 12 * 27 * 3.95 }
quantity of energy required to heat 12 mol of aluminium for 72 deg C to its melting point 658 C
so energy applied is 1451 057 . 33 J
Answer:
The answer is 2.011 *10^24
Explanation:
Looking for atoms in boron,
Molar mass of B = 10.81g/mol
There is 36.1g of B,.
Using avogadro constant = 6.023* 10^23
36.1g of B= 6.023 *10^23/10.81 * 36.1g
That is, 6.023*10^23 divided by 10.81 multiplied by 36.1g
From this calculation, we get
36.1g of boron = 2.011 * 10^24atoms.
Typical household bleach has a value of pH of 13, so the concentration of H₃O⁺ in household bleach is 1 × 10⁻¹³ M.
<h3>What is pH?</h3>
pH of any solution is defined as the negative logarithm of the concentration of H⁺ ion presnt in the solution.
pH = -log[H⁺]
From this equation we can calculate the concentration of H⁺ ion by removing logarithm as:
[H⁺] =
Given value of pH = 13
[H⁺] = 10⁻¹³ M
Hence, required concentration is 1 × 10⁻¹³ M.
