Please add the statements to choose from, i would love to help :)
Cladogram shows that Osteichthyes should be under group A. Going back to their characteristics, they’re a group of fish that have the derived characteristics of jaws and true bones. So, moving backwards from group A these derived characteristics are clearly traceable, wherein each line is showing a relationship/connection.
Answer:
Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. The greater the force that is applied to an object of a given mass, the more the object will accelerate.
Explanation:
For example, doubling the force on the object doubles its acceleration.
Example 1: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
Answer:
A bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution.
Explanation:
First, recall that:
<em>Molarity of a substance = no of moles of the substance/volume of the solution in liters.</em>
In this case, the number of moles of hydrogen peroxide is 0.95 mole while the volume of the solution is one liter. Thus;
Molarity of hydrogen peroxide = 0.95/1 = 0.95 M.
Also recall that:
<em>no of moles of a substance = mass of the substance/molar mass of the substance.</em>
Thus;
mass of substance = no of moles x molar mass.
In this case, the no of moles of hydrogen peroxide is 0.95 while the molar mass is 34.01 g/mol. Hence;
mass of hydrogen peroxide = 0.95 x 34.01 = 32.31 g
<em>Hence, a bottle that contains 0.95 moles of hydrogen peroxide per liter of solution contains 32.31 g of hydrogen peroxide per liter of the solution. The solution also has a hydrogen peroxide molarity of 0.95 M. </em>
