Molecules of glucose (blood sugar) contain 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
Hope this helped :)
Answer:
0.96mL must be given
Explanation:
First, we need to obtain the mass of Solumedrol required for the child by using its mass. Then, with this mass we can solve the volume that must be administered:
<em>Mass of solumedrol required:</em>
20kg * (3mg / kg) = 60mg of solumedrol are required.
<em>Volume given:</em>
<em>60mg Solumedrol * (2mL / 125mg) = </em>
<em />
<em>0.96mL must be given</em>
Answer:
3.25 M
Explanation:
Number of moles = mass/ molar mass
mass of NaOH = 65 g
Molar mass of NaOH = 40 g/mol
Number of moles of NaOH = 65g/40 g/mol = 1.625 moles
Let us recall that;
n = CV
n = number of moles of solute
C = concentration of solution
V = volume of solution
C = n/V
n = 1.625 moles
V = 500/1000 L = 0.5 L
C = 1.625 moles/0.5
C = 3.25 M
Answer:
In simple words, in an open system, the system that has external interactions. Such interactions can take the form of information, energy, mass etc. So keeping this definition in mind, the law of conservation of mass in open system is difficult because when chemical reaction takes places things change form and some things are released as energy, That energy than escapes the system and interacts with other surrounding. This is why it is difficult to demonstrate Law of Conservation of Mass because the changes in mass due to chemical reaction cannot be accounted for properly since the lost mass (in form of energy) was lost to environment.
Whereas, in closed system, all components occur inside a closed container or something where external interactions are minimal to none so the energy lost due to chemical reaction does not escape the system thus it can be accounted for properly to demonstrate the law of conservation of Mass.
Explanation:
Too many words but should get the point across hopefully!
Answer:
Explanation:
Hello,
In this case, the molecular chemical reaction is written as:
In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:
Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:
