The words aa q.s. is an abbreviation which is used in pharmacy. This is usually written by prescribers and then translated by pharmacists. The aa is derived from Latin which means “of each” while q.s. is also derived from Latin which means “a sufficient quantity”. This simply means that there is equal amount of Hytone 1% cream and Lotrimin 1% cream in the total cream formulation.

Since we are to make a total of 60 g of cream, therefore 50% of it would be Lotrimin cream.

Amount of Lotrimin cream needed = 0.5 (60 g)

<span>Amount of Lotrimin cream needed = 30 grams</span>

Answer:

0.6~g~of~lotrimin

Explanation:

We have to keep in mind that the amount of lotrimin in the cream is 1%. Now the total of cream we want to make is 60 g. So, we have to ask us, what is 1% of 60 g? If we keep in mind that if we have 1% indicates that in 100 g of cream we have 1 g of lotrimin we can do the calculation:

60~g~of~cream\frac{1~g~of~lotrimin}{100~g~of~cream}

0.6~g~of~lotrimin

charle [14.2K]
Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)

Products: Carbon dioxide (CO₂) and Water (H₂O)

Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.

Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O

Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O

The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.

Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.

What would a scientist’s next steps be if his/her data failed to support their hypothesis?

To change only one variable which is very important than to test the experiment to match the hypothesis again, I think. It’s been a while since I was on that lesson‍♀️

In the liquid and solid states, molecules are held together by attractions called intermolecular forces. there are several types
BaLLatris [955]
<span>Since these molecules are all non-polar, the only intermolecular force of attraction will be London dispersion forces. Since these increase by the size of the molecule, the boiling points will decrease in the same order: Parafin > Heptadecane > hexane > 2,2-dimethylbutane > propane For these two, hexane > 2,2-dimethylbutane, dispersion forces are greater in a molecule which is longer and unbranched compared to one which is branched and more compact.</span>
