A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
B. Low concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
C. High concentration of oxygen in the blood; low concentration of carbon dioxide in the body tissues
D. Low concentration of oxygen in the blood; low concentration of carbon dioxide in the body tissues
Answer:
A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues
Explanation:
Diffusion occurs from a region of higher concentration to a region of lower concentration. Diffusion occurs against a concentration gradient.
High concentration of oxygen in the blood causes oxygen to leave the blood and enter body tissues. High concentration of carbon dioxide in the body tissues causes carbon dioxide to leave body tissues and enter the blood.
It will expand, because the neon atoms will get larger.
It will expand, because the neon atoms will move more quickly and get farther apart.
It will shrink, because the neon atoms will lose energy as heat, and move closer together.
Answer: It will expand, because the neon atoms will move more quickly and get farther apart.
Explanation: This can be explained based on Charle's law.
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
Thus if a gas absorbs heat at constant pressure and no of moles, the temperature of the gas increases and thus the volume also increases and thus it expands by gaining kinetic energy and moving far apart.
A Brønsted-Lowry base is a species that accepts a proton (hydrogen ion) from another species. NH3, OH-, and even water itself are examples of Brønsted-Lowry bases, denoting they accept protons.
A Brønsted-Lowry base is a species that can accept a proton (a hydrogen ion) from another species. For instance, in a reaction between water and ammonia, NH3 is the Brønsted-Lowry base because it accepts a proton from water. This means that any species capable of accepting a proton, such as hydroxide ion (OH-), ammonia (NH3), or water itself can be considered a Brønsted-Lowry base.
For example, think about the dissociation of water:
H2O + H2O ⇌ H3O+ + OH-
In this reaction, water is acting as both a Brønsted-Lowry acid and a Brønsted-Lowry base. One water molecule donates a proton and becomes a hydroxide ion (the conjugate base), while the other accepts a proton to become hydronium (the conjugate acid).
Another example would be the ionization of ammonia in water:
NH3 + H2O ⇌ NH4+ + OH-
Here, ammonia (NH3) is the Brønsted-Lowry base as it accepts a proton from water to become ammonium (NH4+).

Answer : The mass lost would be,
Solution : Given,
Energy released =
Speed of light 'c' =
Formula used :
where,
E = energy
m = mass
c = speed of light
Now put all the given values in the above formula, we get
Therefore, the mass lost would be,
