VLD [36.1K]

Answer:

The answer to your question is an acid base reaction

Explanation:

A single replacement reaction  is a reaction in which one metal replaces the cation of a compound. The reaction of this problem is not of this type because here the reactants are compounds no single elements.

A decomposition reaction  is a reaction in which one compound decomposes into two or more products. This is not the answer to this question because in this reaction there are two reactants not only one.

A synthesis reaction  is a reaction in which two reactants form only one product. The reaction of this problem is not of this type because there are two products not only one.

An acid-base reaction is a kind of double replacement reaction. In some acid-base reactions, there is an interchange of cations and anions like is shown in this reaction.

A typical aspirin tablet contains 5.00 grains of pure aspirin analgesic compound. The rest of the tablet is
Pavel [41]

Answer:

Tablets=193

Explanation:

Hello,

In this case, given that a typical aspirin tablet contains 5.00 grains of pure aspirin, the first step here is to compute the mass of those grans per tablet given that 1.00 g = 15.4 grains:

m=5.00grains*\frac{1.00g}{15.4grains}=0.325g

In such a way, the number of aspirin tablets are computed considering the total mass of aspirin and the mass per tablet:

Tablets=\frac{62.7g}{0.325g}\\ \\Tablets=193

Best regards.

whg doe sthe transfer of electrons from magnesium to oxygen cause the ions produced to attract eachother
almond37 [142]
Oxygen gains two electrons when it bonds to form a complete outer shell and magnesium loses two electrons when bonding to gain its full outer shell. 

As electrons are negative, the oxygen (which gains electrons) will become negative and the magnesium (which loses electrons) will become positive.

The negative and positive ions will then attract to one another due to the magnetic pull of the positive and negative.
