Answer:
Explanation:
The chemical equation is
For simplicity, let's rewrite this as
1. Initial concentration of NH₃
2. Calculate [OH]⁻
We can use an ICE table to do the calculation.
B + H₂O ⇌ BH⁺ + OH⁻
I/mol·L⁻¹: 0.100 0 0
C/mol·L⁻¹: -x +x +x
E/mol·L⁻¹: 0.100 - x x x
Check for negligibility:
\
3. Solve for x
4. Calculate the pH
There are 0.5 moles of NaCl present in a 29.22g sample.
to find moles of a compound you would look at the periodic table to find the mass. in this case, the mass of NaCl is 58.44 g/mol. now, you divide the sample mass of 29.22g by 58.44 g/mol. the grams will cancel each other out and you’re left with 0.5 mol in that sample
hope this helps!
Molar mass:
CH₄ = 12 + 1 x 4 = 16.0 g/mol
CO₂ = 12 + 16 x 2 = 44.0 g/mol
Balanced <span>equation :

<span>CH</span>₄<span> + 2 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O
</span>
16.0 g CH₄ --------------- 44.0 g CO₂
(mass of CH₄) ----------- 46.4 g CO₂
mass of CH₄ = 46.4 x 16.0 / 44.0
mass of CH₄ = 742.4 / 44.0
= 16.87 g CH₄
hope this helps!
Answer: ATP is the energy currency molecule which is required for cellular processes.
Explanation:
When the cell require metabolic energy to perform a particular a task. From the ATP or adenosine triphosphate molecule one of three phosphate molecule gets displaced and liberates the resulting molecule becomes adenosine diphosphate or ADP. The phosphate molecule is used by the cell to perform different cellular and metabolic functions as a source of metabolic energy. The phosphate is released by the hydrolysis of the phosphoanhydride bond with the other phosphate group.
C is the answer to the question
