Answer:
A drug administered at a rate of 13.5 cL/hour has a rate in μL/s of 37.5 μL/s
Explanation:
The given rate at which the blood is administered = 13.5 cL/hour
The rate at which the question asked to be administered = μL/s
The conversion factor between cL and μL is given as follows;
1 cL = 10,000 μL
Which gives;
13.5 cL/hour × 10,000 μL/cL × 1 hour/(60 × 60 seconds) = 37.5 μL/s
Therefore, a drug administered at a rate of 13.5 cL/hour has an administration rate of 37.5 μL/s.
Answer:
<em>The molarity of the solution is 0,47 M</em>
Explanation:
Molarity is a concentration measurement that expresses the moles of solute (in this case NaOH) in 1 liter of solution (1000ml). First we calculate the mass of 1 mol of NaOH, to calculate the moles in 58.8 g of said compound:
Weight 1 mol NaOH= Weight Na + Weight O + Weight H=23 g + 16 g +1 g
Weight 1 mol NaOH= 40 g/mol
40 g ---1 mol NaOH
58,8g---x= (58,8g x 1 mol NaOH)/40g =1,47 mol NaOH
3,1 L solution ------1,47 mol NaOH
1 L solution --------x= (1 L solution x 1,47 mol NaOH)/3,1 L solution
<em>x= 0,47 mol NaOH ---> The molarity of the solution is 0,47 M</em>
Valence electrons in metallic bonding occupy whole piece of metal, they do not connected to particular atom,
in ionic they move to more electronegative atom, in covalent bond they between atoms ( covalent polar located closer to more electronegative)
An aerosol mixture of particulates and sulfur compounds form a grayish-colored substance that is called <u>industrial smog</u>.
<h3>What is Particulate Matter?</h3>
Airborne particulate matter (PM) is a composite of several chemical species rather than a single contaminant. It consists of a complex mixture of solids and aerosols, including dry solid particles, liquid-coated solid cores, and minute liquid droplets. Particles can contain inorganic ions, metallic compounds, elemental carbon, organic compounds, and chemicals from the earth's crust. They can vary greatly in size, shape, and chemical makeup. For the goal of regulating air quality, the particle diameter is used.
Those that have a diameter of 10 microns or below (PM10) are inhalable and can have a negative impact on health. Particles with a diameter of 2.5 microns or less are considered to be fine particulate matter (PM2.5). Consequently, a percentage of PM10 is made up of PM2.5.

Assuming that the number of mols are constant for both conditions:
![\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BP_1V_1%7D%7BT_1%7D%20%3D%20%20%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
Now you plug in the given values. V_1 is the unknown.
![\frac{0.50 atm*V_1}{325K} = \frac{1.2 atm* 48 L}{230K} ](https://tex.z-dn.net/?f=%5Cfrac%7B0.50%20atm%2AV_1%7D%7B325K%7D%20%3D%20%5Cfrac%7B1.2%20atm%2A%2048%20L%7D%7B230K%7D%0A)
Separate V_1
![V_1= \frac{1.2 atm* 48 L * 325K }{230K*0.50 atm }](https://tex.z-dn.net/?f=V_1%3D%20%5Cfrac%7B1.2%20atm%2A%2048%20L%20%2A%20325K%20%7D%7B230K%2A0.50%20atm%20%7D)
