Eyewash stations should be installed within 25 feet of hazard locations. True or False

2 answers:

7 0

The answer to this question would be: False
<span>Occupational Safety and Health Administration (</span>OSHA) states that the eyewash station should be located "within the work area" and it was interpreted as 10 feet unimpeded travel distance from the hazard location. This distance is calculated in order to avoid potential mixture of substance between the eyewash station and the one that exist on hazard location.

What does electric current measure?

9966 [12]

Answer:

Explanation:

Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time. ... Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR.

Assuming that the F−18 can be transported at 59.0 miles/hour, how close must the hospital be to the cyclotron if 68% of the F−18

tekilochka [14]

Answer:

60.12 miles

Explanation:

Using the calculation formula shown below:

$t_{1/2} =\frac{t}{[tex]log_{2}$ \frac{N_{o} }{N_{t} } }[/tex]

where:

$t_{1/2}$ is the half life, $N_{o}$ is the original amount of F-18, and $N_{t}$ is the remaining amount of F-18 at time t.

Generally, F-18 has an half life of 1.83 hours.

Therefore:

$t = 1.83*[tex]log_{2}$ \frac{100}{68} = 1.02 hours[/tex]

Therefore using a speed of 59 miles/hour, the closeness of the hospital is:

distance = speed*time = 59*1.02 = 60.12 miles

What is the pH of a solution with a concentration of 5.2 × 10–8 M H3O+?

lora16 [44]

Answer : The pH of a solution is, 7.28

Solution : Given,

Concentration of hydronium ion, $H_3O^+$ = $5.2\times 10^{-8}M$

pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.

$pH=-\log [H_3O^+]$

Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.

$pH=-\log (5.2\times 10^{-8})=7.28$

Therefore, the pH of a solution is, 7.28

Enough of a monoprotic acid is dissolved in water to produce a 0.0121 M solution. The pH of the resulting solution is 6.49. Calc

Hitman42 [59]

Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.
