In a titration experiment, a 10.00 ml sample of H2SO4 was titrated with 33.25 mL of 0.777 M KOH.
german

Answer:

1.292 M

Explanation:

<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>

H_2SO_4 + 2KOH --> K_2SO_4 + 2H_2O

Using the formula:

CaVa/CbVb = na/nb

where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.

In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2

Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2

Ca = 1.292 M

Hence, the concentration of H2SO4 is 1.292 M

How is heart rate collected during the ymca 3-minute step test to evaluate the cardiorespiratory fitness level of an individual?
vredina [299]

It is measured over a 60-second count immediately following the test.

After completing the test, the individual sits while the fitness professional palpates the radial pulse (within 5 seconds of test completion) and measures the number of heartbeats over the ensuing 60 seconds.

<h3>What is cardiorespiratory fitness?</h3>

Cardiorespiratory fitness (CRF) refers to the ability of the cardiovascular and respiratory systems to oxygenate the mitochondria of skeletal muscle  for the energy production required during physical activity. CKD is an important indicator of adolescents' physical and mental health and academic performance.

Forms of exercise that rely on cardiorespiratory endurance include strenuous distance running, swimming, and cycling. This aspect of fitness  also affects your ability to perform low-intensity, sustained, full-body exercises, such as  walking, without feeling undue fatigue.

Walking briskly, climbing stairs, doing household chores. High levels of physical activity and cardiorespiratory fitness (referred to simply as “fitness” in this article) are associated with reduced all-cause and cardiovascular mortality. In addition, physical activity can reduce the incidence of chronic diseases such as hypertension, diabetes, stroke and cancer.
