Gabbro and basalt are two igneous rocks having the same chemical composition, and the same minerals (plagioclase feldspar + pyroxene), but are of different origins. Gabbros form at depths and cool slowly, whereas basalts are volcanic rocks that crystallize rapidly at the surface of the earth.

6. Develop Models You are in charge of coaching a team of runners for the next school year. They begin practicing a month before
erastovalidia [21]

As the coach of the team, it is good advice for athletes to keep strictly to their training schedule. Consistency is more important than periodic but prolonged training. This is because the latter tends to wear out the athlete physically and creates longer come-back inertia.

<h3>What is a Training Schedule</h3>

A Training Schedule is a plan that you must design to ensure that you support a team of athletes with the required amount of training. A properly designed schedule will contain:

  • Calendar of training to be introduced to the students;
  • Details of the training and other related agenda
  • List of trainees and trainers

What weight of Tris-HCL (MW=121) is required to prepare 2L of a 15% w/v solution?
podryga [215]

Explanation:

Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.

Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.

                 \frac{15 g}{100 ml} \times 2000 ml

                  = 300 g

Thus, we can conclude that weight of Tris-HCL required is 300 g.
