The force of an object due mass and gravity.it can also be defined as the force exerted by gravity on a body
pH is the potential of the hydrogen in the aqueous solution. The pH of the hydrosulfuric acid is 0.6.
<h3>What is pH?</h3>
pH is the hydrogen or the hydronium ion concentration in the aqueous solution. The formula to calculate pH is given as,
![\rm pH = \rm - log [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20pH%20%3D%20%5Crm%20-%20log%20%5BH%5E%7B%2B%7D%5D)
Since hydrosulfuric acid is diprotic the concentration of the hydrogen ion will be:
![\begin{aligned} \rm [H^{+}] &= 2 \times 0. 571 \;\rm M \\\\&= 1.142\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%5Crm%20%5BH%5E%7B%2B%7D%5D%20%26%3D%202%20%5Ctimes%200.%20571%20%5C%3B%5Crm%20M%20%5C%5C%5C%5C%26%3D%201.142%5Cend%7Baligned%7D)
Now, pH is calculated as:
![\begin{aligned} \rm pH &= \rm - log [H^{+}]\\\\&= \rm - log [1.142]\\\\&= 0.06\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%5Crm%20pH%20%26%3D%20%5Crm%20-%20log%20%5BH%5E%7B%2B%7D%5D%5C%5C%5C%5C%26%3D%20%5Crm%20-%20log%20%5B1.142%5D%5C%5C%5C%5C%26%3D%200.06%5Cend%7Baligned%7D)
Therefore, 0.6 is the pH of the hydrosulfuric acid solution.

Answer:
3000J
Explanation:
Formula: Work = Force × Distance
Solution: Work = 200N × 15m
Answer = 3000N/m or 3000J
First you would divide your weight on Earth by 9.8m/s which is the gravitational constant. This would give you your mass which would be 10.2 kg. To find the gravity of the unknown planet you would multiply 9.8m/s by 15 which would be 147m/s. Since weight is defined as mass times gravity you would substitute the mass you found earlier and multiply it by the new gravity. This would give you 10.2kg times 147 m/s which equals 1,499.4 lbs or 1,500 lbs if rounding.
Well here are the Main Chemicals, Compounds and Components
- the two main components are carbonated water and caramel color
- molecular formula for carbonated water is H2CO3
- Molecular formula for caramel color is C18H9N Na2O8S2
- Carbonated water is water that contains carbon dioxide gas, the gas causes there to be small bubbles in the water
- Caramel color is the most consumed food coloring ingredient in the world, it results from controlled heat treatments of carbohydrates
