The answer would be D. (The 4th one listed).
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms.
Hope this helps!
Answer:
The answer will result in one significant digit.
Explanation:
1. Subtract:
12.1 - 12.004 = 0.096
2. ROund to the correct number of significant digits:
For addition and subtraction we round the sum or the difference to the least number of digits after the decimal point there are in the problem.
For example, SInce 12.1 has one number after the decimal point and 12.004 has three numbers after the decimal point, we round the answer to one number after the decimal point because 12.1 is the number in the problem which has the least amount of digits after the decimal point.
We round 0.096 to 0.1.
0.1 has one significant digit.
<u>Answer:</u> The equilibrium concentration of hydrogen gas is 0.0222 M
<u>Explanation:</u>
We are given:
Initial concentration of hydrogen gas = 0.041 M
Initial concentration of iodine vapor = 0.041 M
Initial concentration of hydrogen iodide = 0.115 M
For the given chemical equation:
Initial: 0.041 0.041 0.115
At eqllm: 0.041-x 0.041-x 0.115+2x
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
Neglecting the value of x = 0.0816 because, equilibrium concentration cannot be greater than the initial concentration
So, equilibrium concentration of hydrogen gas =
Hence, the equilibrium concentration of hydrogen gas is 0.0222 M
Any atom can be considered stable if it has an equal number of protons and electrons, giving it a net charge of zero. If this balance does not occur that atom is ionized.
