You need 4.0 ounces of a steroid ointment. if there are 16 oz in 1 lb, how many grams of ointment does the pharmacist need to pr
Bond [772]

The given units are the units of masses which are interconvertable.

It is given that:

1 lb = 16 oz

Now, converting kg to lb:

Since, 1 kg = 2.20462 lb

So, \frac{0.0625 lb}{1 oz}\times \frac{1 kg}{2.20462 lb}

Now converting kg to g:

Since, 1 kg = 1000 g

So, \frac{0.0625 lb}{1 oz}\times \frac{1 kg}{2.20462 lb}\times \frac{1000 g}{1 kg} = 28.349 \frac{g}{oz}

For 4 oz:

28.349\frac{g}{oz} \times 4 oz = 113.396 g

Thus, 113.396 g of ointment needed to be prepared by the pharmacist.

CaCl2 + Na2CO3 → CaCO3 + 2 NaCl
Nana76 [90]

Answer:

8.45 moles are produced

Explanation:

CaCl₂ + Na₂CO₃ → CaCO₃ + 2 NaCl

From the equation, we can see that for every 1 mole of CaCl₂  and 1 mole Na₂CO₃ will give 1 mole of CaCO₃ and 2 moles of NaCl

to calculate how many moles of CaCO₃ ,we simply multiply multiply each by the 8.45 moles of CaCl₂ which will reacts

these is because for every 1 mole of CaCl₂  and 1 mole Na₂CO₃ will give 1 mole of CaCO₃ and 2 moles of NaCl

therefore we have every 1x8.45(8.45)  mole of CaCl₂  and 1x8.45(8.45) mole Na₂CO₃ will give 1x8.45(8.45) mole of CaCO₃ and 2x8.45(16.9) moles of NaCl

8.45 moles are produced in the reaction

Hydrogen bonds are in the family of Van der Waals forces. They are weaker than ionic and covalent bonds but they cause interesti
-Dominant- [34]

Answer:

The answer is B. Van der Waals forces are weaker than ionic and covalent bonds.

Explanation:

In general, if we arrange these molecular forces from the strongest to weakest, it would be like this:

Covalent bonds > Ionic bonds > Hydrogen bonds > Dipole-Dipole Interactions > Van der Waals forces

Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.

Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.

Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.
