Answer:
The answers are in the explanation
Explanation:
For the equilibrium:
B(aq) + H₂O(l) ⇌ HB⁺(aq) + OH⁻(aq).
By LeChatelier's principle, the increase in the concentration of a reactant (for example) at equilibrium will change the system counteracting the increasing producing more product.
Thus,
A) Will the equilibrium constant for the reaction increase, decrease, or stay the same? Why?
.
The equilibrium constant is a thermodynamic constant that stay the same with the addition of a compound.
B) Will the concentration of HB⁺(aq) increase, decrease, or stay the same? Why?
By LeChatelier's principle, the addition of B will induce the formation of more HB⁺(aq) increasing the concentration.
C) Will the pH of the solution increase, decrease, or stay the same? Why?
As the addition of B induce the increasing of OH⁻, the pH of the solution will increase.
I hope it helps!
"B. purple" is the correct answer.
i believe that it is the third one
<h2><u>Answer:</u></h2>
Lico. The stone was unclear range from the including territory. Between 130 million and 500 million years back, magma from volcanoes cooled to shape the stone that would advance toward getting to be Mt.
On Mount Lico in northern Mozambique is a site that few have had the enjoyment of seeing – a hid rainforest, verified by an unsafe float of shake. In spite of the way that the mountain was known to neighborhood individuals, the forested areas itself remained a secret until six years back, when Julian Bayliss spotted it on satellite imagery.
Answer:
False
Explanation:
A significant number is a number that is used to express the accuracy in a measurement. There are some rules that binds the identification of significant figures when reporting a scientific measurement.
- All non-zero numbers are significant
- Zeros in between two digits are significant.
- Zeros to the right of the decimal are significant.
- Leading zeros are just place holders and are not significant.
- Trailing zero in a whole number with decimal is significant
- Trailing zero without a decimal is not significant.

We can see that not all zeros in a measurement is significant. For example, 540 has 2 significant numbers because the zero is not significant but 540.2 has 4 significant numbers.
