Answer:
The pH would be 1.
Explanation:
The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.
Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.
By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
= 1
The pressure of the gas = 40 atm
<h3>Further explanation</h3>
Given
200 ml container
P = 2 atm
final volume = 10 ml
Required
Final pressure
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
Input the value :
P₂ = P₁V₁/V₂
P₂ = 2 x 200 / 10
P₂ = 40 atm
Answer:
Weight of boulder = 22,400 gram
Explanation:
Given:
Volume = 8,000 cm³
Density = 2.8
Find:
Weight of boulder
Computation:
Weight of boulder = Volume x Density
Weight of boulder = 8,000 x 2.8
Weight of boulder = 22,400 gram
Answer: Thin pancakes with milk are the English version of traditional fluffy Russian pancakes baked with yeast. In Europe, pancakes look like thin, almost transparent napkins. In France they are called "crepes" and are served with hundreds of different fillings. There are no special tricks in cooking: the thinner the dough, the thinner the pancakes are. An openwork version, in a hole, will work if part of the milk from the recipe is added to the dough a little hot. Before pouring the first pancake, you should heat the pan well. The pancake is ready when it begins to brown until crispy.
Explanation:
That's what the other person said it's in russian and its a recipe.
