Answer:
18.2784 g
Explanation:
First we <u>convert 180 lb to kg</u>:
- 180 lb * 0.453 kg / lb = 81.6 kg
Now we <u>calculate the mass of antibiotic taken in one day</u>:
- 8.0 mg/kg * 81.6 kg = 652.8 mg
Given that it is taken twice daily, <em>in one day the person would take (652.8 * 2) 1305.6 mg</em>. In grams that mass would be:
- 1305.6 mg / 1000 = 1.3056 g
Finally we multiply those 1.3056 daily grams by the 14 days in two weeks:
- (1.3056 g) * 14 = 18.2784 g
Once a metal is above another in series it is more reactive than it and will be able to displace it from its compound. Ex: Iron will displace lead from its compound but Iron cannot displace zinc from its compound.
Hope this helps!
Answer:
True
Explanation:
True. Metals produces oxides with oxygen
the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.
<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>
As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.
