It won't be possible for me to answer this question if there is no context. I tried to find a similar question and I came up with one. The problem is shown in the attached picture. From the given choices, all their units are atm*mL. So, that means that P*V. The answer could only be (2) or (4). Let's try the data in the table to find out.
PV = (0.5 atm)(1000 mL) = 500 atm*mL
PV = (1 atm)(500 mL) = 500 atm*mL
PV = (2 atm)(250 mL) = 500 atm*mL

<em>Thus, the answer is choice (2).</em>
A)Calcium-This because calcium has two valence electrons hence it is a metal therefore it will form an ionic bond with carbon.
The answer is 10 grams.
The atomic weights for each elements are :
<span>Na - 22.99 g/mol </span>
<span>O - 16.00 g/mol </span>
<span>H - 1.01 g/mol
The sum = 40 g/mol for NAOH
</span><span>0.250 moles * 40.00 g / 1 mole = 10 g NaOH</span>
Answer:
secondary, because there are some remains of the previous community (C)
Explanation:
Answer: The answer is B
Explanation: Looking at the table given, the more wire loops you put on the nail, the more paperclips that it can hold. Meaning the electromagnet gets stronger the more loops you put on the nail
