T = 2500 + 100c
where t is his total monthly salary and c is the number of cars he sold in a given month
Atoms are real even though they're invisible.
Answer:
6.57 L
Explanation:
First, calculate the <em>moles of hydrogen</em> produced, then use the Ideal Gas Law to calculate the <em>volume of hydrogen</em>.
Step 1. Write the <em>chemical equation</em>.
: 22.99
2Na + H₂O ⟶ 2NaOH + H₂
Step 1. Convert <em>grams of Na</em> to <em>moles of Na</em>
Step 2. Use the molar ratio of H₂:Na to convert <em>moles of Na</em> to <em>moles of H₂</em>.
Step 3. Use the Ideal Gas Law to calculate the <em>volume of hydrogen</em>.
<em>pV = nRT</em>

Answer:
D. It is extremely reactive.
Explanation:
Hello!
In this case, since potassium is an alkali metal, it is known those are extremely reactive because the energy required to ionize them is very low, it means they react so easily. For instance, even in the presence of water, potassium is able to react and form a purple flame as a product of the reaction:
As well as potassium, the rest of the elements belonging to the alkali metals series are extremely reactive; therefore the answer is D. It is extremely reactive.
Best regards!
