An estuary is partly enclosed and forms a transition zone between rivers and oceans/ seas
Answer:
First step would be convert to moles
Final Answer: 37.8 g of NaCl
Explanation:
The reaction is:
2Na + Cl₂ → 2NaCI
We convert the mass of each reactant to moles:
18 g . 1mol /23g = 0.783 moles of Na
23g . 1mol / 70.9g = 0.324 moles of chlorine
We use the mole ratio to determine the limiting reactant:
Ratio is 2:1. 2 moles of Na react to 1 mol of chlorine
Then, 0.783 moles of Na, may react to (0.783 . 1)/2 = 0.391 moles.
Excellent!. We need 0.391 moles of Cl₂ and we only have 0.324 moles available. That's why the Cl₂ is our limiting reactant.
We use the mole ratio again, with the product side. (1:2)
1 mol of Cl₂ can produce 2 moles of NaCl
Then, our 0.324 moles of gas, may produce (0.324 . 2)/1 = 0.648 moles
Finally, we convert the moles to grams:
0.648 mol . 58.45g/mol =
Answer:
Tetracycline and antacid should not be given together.
Explanation:
In the given order, tetracycline and antacid are given together. The antacid is in the aspirin. The tetracycline and antacid should not be used together because the presence of antacid will suppress the effectiveness of the tetracycline. This is because antacid contains chemical compounds such as sodium bicarbonate which can interact with the tetracycline.
Answer:
8 mol of hydrogen will react with 1 mol of sulfur.
Explanation:
We'll begin by writing the balanced equation for the reaction.
This is given below:
8H2 + S8 —> 8H2S
Now, let us carefully observe the mole ratio of the reactants.
This is illustrated:
The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1
From the balanced equation above,
We can thus, concluded that:
8 moles of H2 will reacted with 1 mole of S8.
Answer:
B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula tells about the ration of the elements found in the compound . The ratio are in complete number .
For example the molecular formula of glucose is C₆ H₁₂O₆
Its empirical formula = CH₂O
