Answer:
C. Cs, because it has the lower ionization energy and more easily gives up its valence electrons to participate in a reaction.
Explanation:
The Cs will produce the most hydrogen gas because it has a lower ionization energy and more easily gives up its valence electrons to participate in the reaction.
- Ionization energy is the energy required to remove the most loosely held electrons in an atom.
- Atoms with lower ionization energy readily goes into reactions.
- This is because they will present little barrier for the reaction to occur.
Answer:
i am very sorry i have no answer but if i get one i can tell u the answer
Explanation:
Answer:
The trees' growth might be affected
Explanation:
A pH above 7 indicates that the soil is no more acidic and that it had turned basic or alkaline in nature. This may affect the functioning of enzymes as this value is very far from optimum pH value. Thus growth is affected.
The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.
<h3>
What is solubity ?</h3>
It is the ability of a solute to be dissolved, especially in water.
As the temperature increases the solubility of the gas generally decreases"
According to given information and graph attached as reference ;
- Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
- Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
- Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9
grams. - Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.
- Solubility of Ce₂(SO₄)₃·9H₂O (ceasium sulfate nonahydrate) at 40°C is 6.2 grams.
