The answer to this question B (10+10)/(5-3)
It’s newton’s first law but that’s a physics question
1. Mixing of condiments, water and other ingredients to cook something delicious. In this case, the proportions of those components matter in creating the food.2. Selling things based on precursors and determining the limiting reactant so as to maximize profit. 3. Buying stuffs and analyzing their ingredient content.
Answer : The correct option is A) Stable.
Explanation :
Ionic compound : Ionic compounds are the compounds which are made up of an ions that are cations and an anions. The cation are positively charged and an anions are negatively charged.
The ionic bonds are stable when cation and an anions both approaches to each other by electrostatic force, they form ionic bonding.
Therefore, the correct option is A) Stable.
0.16 M of Cu
<u>Explanation:</u>
Molarity = moles/volume
Here, we have to find the moles from the molar mass of CuSO₄. 5H₂O is 249. 71 g/ mol
Now we can find the moles as,
1 g CuSO₄. 5H₂O × ( 1 mol CuSO₄. 5H₂O / 249. 71 g of CuSO₄. 5H₂O) × 1mol of Cu / 1 mol CuSO₄. 5H₂O
= 0.0040 mol Cu
Now we have to find the concentration in terms of molarity as,
molarity = moles/ volume = 0.0040 moles/ 0.025 L = 0.16 M of Cu.
