Answer:
The limiting reactant is the 6.279 g of
Explanation:
We have to start with the <u>reaction</u> between sodium carbonate () and the Nickel (II) Chloride (), so:
We will have a <u>double replacement reaction</u>. Now we have to <u>balance</u> the reaction, so:
The next step is the <u>calculation of the moles for each reactive</u>. For we have use the <u>molarity equation</u>:
For the calculation of moles of we have to use the <u>molar mass</u> of the compound (129.59 g/mol):
The next step is the division of each mole value by the <u>coefficient of each reactive</u> of the balance reaction. In this case <u>we have "1" for each reactive</u>, so:
The final step is to <u>choose the smallest value</u>. In this case is the value that correspond to . Therefore is the limiting reactive.
- Endothermic reaction means the reactant side takes heat from surrounding and get decomposed i.e ∆H=-ve
- If the equation is exothermic then it means the reactant is happy to decompose .But it's not as it's endothermic
Now
- HgO is Omitted from our solution option.
Hg is a atom so no bonds hence no bond strength occurs.
- O_2 is a molecule and so it's our answer .
Since the chemical definition of "stable" means close to having a full valence shell, the answer is 3d^10.

The answer is starch because iodine reacts with starch to change the colour to inky blue or black.
All the others are present in milk naturally so I’m assuming they intent starch
