A physician has ordered 0.50 mg of atropine, intramuscularly. If atropine were available as 0.10 mg/mL solution, how many mL would u need to give?
Answers
x = 0.50 mg / 0.10
x = 5.0 mL
hope this helps!

Dot structures only show the valence electrons of an atom which are the electrons found at the outermost shell. The orbital notation gives a more detailed depiction of the electrons in each shell. This is most advantageous for atoms that have special cases.
Some examples of atoms that have special electronic configurations are copper and chromium. For example, copper is more stable when the 3d subshell is completely filled. This leaves the 4s subshell with only 1 electron. Chromium is also more stable when its s and d subshells are only half full. The orbital notation depicts these special cases, whereas the dot structure does not.

2. Orbital notation shows the spin of the electrons.

Molecules always move in most objects, but in solids, they are extremely slow. Liquids move slower than gases, but move more than solids.
Final answer:
Molecules do move in a liquid, as they are free to slide past each other and change neighbors due to their mutual attraction. This allows liquids to flow and take the shape of their containers. The speed of this movement can depend on the mass of the molecules - lighter ones move and diffuse faster.
Explanation:
Yes, indeed, molecules do move in a liquid. This is due to the fact that liquids are typically in a more energetic state in which their particles can slide past one another and change neighbors. However, these particles remain closely held together by their mutual attraction which maintains the liquid's lack of shape conformity.
In liquids, unlike solids, the atoms or molecules are free to move around, which contributes to them being classified as a type of fluid. Due to their capacity to flow and rearrange their molecular structure, liquids deform easily when under stress. Once the force is removed, they don't return to their initial form, which is evidenced when a liquid takes the shape of a container it's put in.
Finally, the movement of these molecules is also somewhat dependent on their mass. Heavier molecules tend to move slower and are therefore slower to diffuse. In contrast, lighter molecules tend to move and diffuse faster.

The statements that are correct are ‘A large Keq value indicates that products are favored.’ And ‘A small Keq value indicates that the reverse reaction will occur very quickly.’ Having large Keq means that the concentration of the product is greater than the reactants and so products are favored. Having small Keq means that the concentration of the reactants is greater than the product.

To calculate the molar mass of a compound, sum the atomic masses of all atoms in the compound. Ammonia has a molar mass of 17.04 g/mol, magnesium hydroxide has a molar mass of 58.33 g/mol, and iron(III) oxide has a molar mass of 159.70 g/mol.
Explanation:
Calculating Molar Mass
To calculate the molar mass of a compound, you sum the atomic masses of each individual element present in the compound, multiplied by the number of each of those atoms in the formula.
Ammonia (NH3): The atomic mass of nitrogen (N) is approximately 14.01 g/mol and hydrogen (H) is approximately 1.01 g/mol. Since ammonia contains one nitrogen atom and three hydrogen atoms, its molar mass would be (14.01 g/mol) + 3 × (1.01 g/mol) = 17.04 g/mol.
Magnesium hydroxide (Mg(OH)2): The atomic mass of magnesium (Mg) is approximately 24.31 g/mol, oxygen (O) is approximately 16.00 g/mol, and hydrogen (H) is again 1.01 g/mol. Magnesium hydroxide has one magnesium atom, two oxygen atoms, and two hydrogen atoms. Thus, its molar mass is (24.31 g/mol) + 2 × (16.00 g/mol) + 2 × (1.01 g/mol) = 58.33 g/mol.
Iron(III) oxide (Fe2O3): The atomic mass of iron (Fe) is approximately 55.85 g/mol and oxygen (O) is 16.00 g/mol. Iron(III) oxide consists of two iron atoms and three oxygen atoms, giving a molar mass of 2 × (55.85 g/mol) + 3 × (16.00 g/mol) = 159.70 g/mol.

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:
P1V1 =P2V2
V2 = P1 x V1 / P2
V2 = 42.0 x 12.5 / 75.0
V2 = 7.0 L
Answer:
7.00 L
Explanation:
The only thing that varies between the two situations is pressure and volume.

Scientists would deal with the aspect of cloning a particular gene into a bacterium or making of hybridoma cells that will produce the particular required protein. Engineers will then design and develop a bioreactor which is a programmed instrument that avails the required substances to the cells/bacteria in specific amounts and at particular time periods to grow and reproduce the cells in large amounts.
