2:1
2:3
3:2
The ratio of Al^3+ ions to S^2- ions in a neutral compound is 2:3.
The neutral compound formed by aluminum ion and sulphide ion is aluminium sulphide, with chemical formula Al2S3. Looking at the chemical equation, you will observe that, for each molecule of aluminium sulphide, there is two atoms of aluminium and three atoms of sulphur. This is the ratio of combination for the compound, that is, for every two atoms of aluminium, there are three atoms of sulphur, thus, the combination ratio is 2:3.
What is a limitation of current atomic models as compared to the Bohr atomic model?
A. Current atomic models do not indicate the position of the nucleus within the atom's structure.
B. Current atomic models do not show how many electrons an atom has.
C. Current atomic models do not show where the electron is but only where the electron is likely to be.
Answer:
The answer is C.
Explanation:
High temperatures increase the activation energy of the reaction.
High temperatures make the gas molecules move more quickly.
The reaction becomes exothermic at high temperatures.
this is wrong do not put this if your with FLVS
the correct answer is C i got 100% on it
B. Distance
C. Displacement
D. Direction
Answer:
direction
Explanation:
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.
