NH₃ + H₂O ⇄ NH₄⁺ + OH⁻
pOH=-lg[OH⁻]
pOH = 14-pH
14-pH = -lg[OH⁻]
[OH⁻]=10^(pH-14)
[OH⁻]=10^(11.8-14)=0.00631 = 6.31·10⁻³ mol/L
Answer:
D
Explanation:
according to boyle's law the temperature and pressure of a gas are inversely proportional given by the equation
p1v1=p2v2
In this case p1 is 9.5,v1 is 1.7,v2 is 1.1 and we have to find p2
9.5×1.7=p2×1.1
16.15/11=1.1p2/1.2
p2=14.7
I hope this helps
If you’re talking about a reaction, an increase in the products (values on the right side of the chemical equation) would cause the reaction to shift left instead of right. Also a decrease in the reactants.
Also, could be wrong, but increasing the volume/ decreasing the pressure on the reactant side will cause the reaction to shift left
Answer: The correct number of significant figures in is 35.05152.
Explanation:
Digits present in a number that helps in determining the degree of accuracy starting from the first non-zero digit is called a significant figure.
Some rules for significant figures are as follows.
- All the digits present within the non-zero digits are considered in a number.
For example, 2085 contains 4 significant digits.
- Leading zeros are not counted in a number.
For example, 0.0034 has 2 significant digits.
- We count the trailing zeros when a decimal point is present in a number.
For example, 0.02500 has 4 significant figures.
- When there is no decimal point then trailing zeros may or may not count.
For example, 19000 has 2 significant digits.
Now, the product of given digits is as follows.
Thus, we can conclude that correct number of significant figures in is 35.05152.
