Answer:

Antimony, it increases as it goes across a period and decreases as it goes down a group. Does potassium or lithium have the smaller atomic radius? Lithium, because as you move across a period it gets weaker and down a group, it gets stronger.

Azithromycin suspension dosing is 10 mg/kg/d and is available in 200mg/5ml doses. how many ml would a 25kg child receive daily?
bekas [8.4K]
The answer to this question is 6.25ml

To answer this question, you need to calculate the azithromycin drug doses for this patient. The calculation would be: 25kg * 10mg/kg/d= 250mg/d

Then multiply the doses with the available drug. It would be:
250 mg/d / (200mg/5ml)= 6.25ml/d

Explanation:

The answer is reduced effectiveness of pesticides.

Genetic engineering has a great advantage in vaccines production or in a pharmaceutical production of desired proteins, such as insulin, human growth hormone, etc. In plant genetic engineering increased drought and salinity tolerance will help plants survive in difficult conditions.

On the other hand reduced effectiveness of pesticides is a disadvantage of using genetic engineering. Genetically modified plants may develop resistance to pesticides, so pesticides are not effective as expected.

Above what temperature does the following reaction become nonspontaneous? FeO(s) + CO(g) → CO2(g) + Fe(s) ΔH = -11.0 kJ; ΔS = -1
Dominik [7]

Answer:

  • 632 K

Explanation:

<u>1) Reaction (given):</u>

<u />

  • FeO(s) + CO(g) → CO₂(g) + Fe(s)     ΔH = -11.0 kJ;

                                                                  ΔS = -17.4 J/K

<u />

<u>2) Spontaneous reactions (ΔG < 0)</u>

The sign of the change in free energy (ΔG) tells if a reaction is spontaneous or not at a given temperature and constant pressure.

If ΔG is negative ( ΔG < 0) the reaction is spontaneous; if ΔG is positive ( ΔG > 0) the reaction is nonspontaneous.

Then, determine the temperature at which ΔG becomes zero, which is the temperature at which the reaction becomes nonspontaneous.

<u>3) ΔG⁰ = ΔH⁰ - TΔS⁰</u>

ΔG⁰ = -11,000 J - T (-17.4 J/ K)  [ -11.0 kJ were converted to J]

0 = - 11,000 J + 17.4 T J/K

11,000 J = 17.4 T J/ k

T = 11,000 kJ / (17.4 J/K) =  632 K ← answer
