Answer:
vinegar and baking soda when mixed forms Carbon dioxide which turns lime water milky.
Explanation:
due to properties of Co2 lime water turns milky. The Answer would be A
metal
gas
H+
OH-
nitrogen
OH- is common to bases.
Explanation:
The base is a is an ionic compounds which when placed in aqueous solution dissociates in to a cation and an anion OH-.
The presence of OH- in the solution shows that the solution is basic or alkaline.
From Bronsted and Lowry concept base is a molecule that accepts a proton for example in NaOH, Na is a proton donor and OH is the proton acceptor.
A base accepts hydrogen ion and the concentration of OH is always higher in base.
There is a presence of conjugate acid and conjugate base in the Bronsted and Lowry acid and base.
Conjugate acid is one which is formed when a base gained a proton.
Conjugate base is one which is formed when an acid looses a proton.
And from the Arrhenius base Theory, the base is one that dissociates in to water as OH-.
Answer:
metal and OH-
Explanation:
If the substance entering the cell was in higher concentration inside the cell than outside the cell, the type of transport that would be required here is known as Active transport. Thus, the correct option for this question is A.
Active transport may be defined as a type of transport that occurs against the concentration gradient and therefore it is mediated by carrier proteins. In this type of transport, metabolic energy is utilized in order to move ions or molecules against the concentration gradient. It is directly opposite to passive transport.
Active transport results in the accumulation of solute on one side of the membrane. It is different from the carrier proteins mediated facilitated diffusion. This transport decreases the entropy of the reaction.
Therefore, active transport would be required in order to migrate any substance from a lower concentration to a higher concentration. Thus, the correct option for this question is A.

Vertical columns on the periodic table are called B. families.
The elements in each column, or family, have B. Similar properties.
In the periodic table, elements are organized into rows and columns based on their atomic number and electron configuration. Each vertical column represents a family or group of elements that share similar chemical and physical properties.
The elements within a family tend to have similar valence electron configurations, leading to similar chemical behaviors and reactivity patterns.
