Solution contains 45% salt
She wants to obtain 180 ounces of a mixture that
is 30% salt
Ounces of water with 45% salt solution = ?
30% = 0.3 and 45% = 0.45
Let V is the volume of water to be mixed in
ounces, then the volume of the 45% salt solution needed is 180-V
The balanced equation for the mass of salt is
0.45 x (180-V) = 0.3 x 180
81 – 0.45V = 54
0.45V = 81-54
0.45V = 27
V = 60
<span>So, 60 ounces of water is needed</span>
Answer:
<h2>The answer is 3.2 g/L</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of cat = 400 g
volume = final volume of water - initial volume of water
volume = 125 - 100 = 25 L
The density of the cat is
We have the final answer as
<h3>3.2 g/L</h3>

The downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.
<h3>Can titanium withstand temperatures?</h3>
Titanium alloys have high tensile strength to weight ratio, good toughness and an ability to bear extreme temperatures of more than 600 °Celsius. This shows that if temperature increase from more than 600 °Celsius, the strength of the titanium tends to decrease because it can not withstand to it so the graph comes to downward when the temperature exceeds to 600°C.
So we can conclude that the downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

Answer:
Rate of forward reaction will increase.
Explanation:
Effect of change in reaction condition on equilibrium is explained by Le Chatelier's principle. According to this principle,
If an equilibrium condition of a dynamic reversible reaction is disturbed by changing concentration, temperature, pressure, volume, etc, then reaction will move will in a direction which counteract the change.
In the given reaction,
A + B ⇌ C + D
If concentration of A is increase, then reaction will move in a direction which decreases the concentration of A to reestablish the equilibrium.
As concentration A decreases in forward direction, therefore, rate of forward reaction will increase.
