The answer is A

According to research I have done, pure solids and liquids are not included in the equilibrium constant expression. If the concentration of a reactant in aqueous solution is increased, the position of equilibrium will move in the direction which minimises the effect of this increase in concentration, by using the added component up, to decrese it's concentration again.

The recommended single dose for acetaminophen is 10.0 to 15.0 mg/kg of body weight for adults. Using this guideline, calculate t
marshall27 [118]

Answer:

1.041g is the maximum sigle dose for the person

Explanation:

The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults

To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):

153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>

<em />

As the maximum dose is 15.0mg / kg, the dose of the person is:

69.4kg * (15.0mg acetaminophen / kg) =

<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>

On a graph, which type of line shows a direct proportion? A. upwardly curved line B. downwardly curved line C. straight line D.j
siniylev [52]
A straight line shows a direct proportion because each x-value has one y-value, and there is a correlation between the two values, not just random placement. Hope this helps! :)

State two methods to increase the rate of the chemical reaction and explain
Jet001 [13]

Answer:

METHOD 1: (surface area of a solid reactant)  METHOD 2: (concentration or pressure of a reactant)

Explanation:

METHOD 1: (surface area of a solid reactant) Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.

METHOD 2: (concentration or pressure of a reactant) Increasing the concentration means that we have more particles in the same volume of solution. This increases the chance of collisions between reactant particles, resulting in more collisions in any given time and a faster reaction. As we increase the pressure of reacting gases, we increase the rate of reaction.

If the mass of 293nv is 293.10 amu and that of 295nv is 295.45 amu , what is the atomic weight of nv?
ycow [4]

Answer;

294.13 amu

Solution;

-293nv is 293.10 amu and that of 295nv is 295.45 amu

293.05+295.2=588.25

588.25/2= 294.13 amu

an amu of 294.13 using significant figures

Please help, answer questions 3-7
tatyana61 [14]
I don’t know about 3 but I know that 4 is solid, 5 is you’ll feel the vibration first, 6 is you’ll see the lightning first because the speed of light is faster than the speed of sound and 7 is sound waves need a medium to travel and light waves don’t, sound waves are longitudinal and light waves are transverse, and sound waves are mechanical waves while light waves are electromagnetic waves
