Answer:
A or C because they both kinda are the same
Its called ionic bonding! :^)
Answer:
Its an ion
Explanation:
A hydrogen ion is created when a hydrogen atom loses or gains an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space.[1] Due to its extremely high charge density of approximately 2×1010 times that of a sodium ion, the bare hydrogen ion cannot exist freely in solution as it readily hydrates, i.e., bonds quickly.[2] The hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes.[3] Depending on the charge of the ion, two different classes can be distinguished: positively charged ions and negatively charged ions
<u>Answer:</u> The concentration of weak acid is 
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of weak acid is
The following reaction: H2 + I2 → 2HI, is an example of synthesis reaction
<u>Explanation:</u>
<u>Synthesis reaction:</u>
- In simple words, synthesis reaction can be stated as two or more material merge to form a new material.
- A synthesis reaction is always exothermic since they deliver power in the form of heat and light.
- When the metal and nonmetals are combined they produce an ionic compound.
- A synthesis reaction is essentially the reversal of decomposition reaction.
- The example of Synthesis reaction would be
- 2 H2(g) + O2(g) -->2 H2O(g)
- 3 H2(g) + N2(g)--> 2 NH3(g)
