Converts the 25 lb to kg
multiply the kilograms by the dose (10 mg/kg)
multiply the amount of ibuprofen by the conversion factor of the concentration of the suspension to calculate the mL
25 lb x 0.453592 kg/1lb= "A kg"
A kg x 10 mg/kg = B mg
B mg x 5.0 mL/ 100 mg = "C mL of suspension"
Answer:
A. They must be kept separate from moisture and oxygen
Explanation:
Alkali metals refers to a group of chemical elements in the periodic table. It is the common name given to Group 1 elements (excluding hydrogen). They are generally metallic in nature with physical properties like shining lustre, silvery in appearance etc. Alkali metals include lithium, Pottasium, Sodium, Rubidium etc.
One important chemical property of alkali metals is their high reactivity i.e. they tend to react quickly with other substances. For example, alkali metals react vigorously with water to form hydroxides. They also react with oxygen to form oxides. Due to this highly reactive properties, they are kept or stored away from moisture (water) and oxygen (present in air).
Answer:
1.14atm
Explanation:
Given parameters:
V1 = 250cm³ ;
1000cm³ = 1dm³; so this is 0.25dm³
P1 = 760torr
760torr = 1atm
V2 = 220cm³ ; 0.22dm³
Unknown:
New pressure = ?
Solution:
To solve this problem, we apply Boyle's law and we use the expression below:
P1 V1 = P2V2
The unknown is P2;
1 x 0.25 = P2 x 0.22
P2 = 1.14atm
88g ( so sorry if this isn’t correct )
Answer: Flow rate is inversely proportional to viscosity.
Explanation: The relation is called Poiseuille's law, which describes the smooth flow of a fluid along a tube.
