Answer:
.900 J / g-C°
Explanation:
I assume you are looking for the specific heat of the metal
Specific heat = J / g-C
= 6640 J / 348 g[ (43.6 - 22.4) ] = .900 J / g-C
Answer:
1019.27 g.
Explanation:
- For the balanced reaction:
<em>2Na + Cl₂ → 2NaCl,</em>
It is clear 2 moles of Na with 1 mole of Cl₂ to produce 2 moles NaCl.
- Firstly, we need to calculate the no. of moles of Cl₂ is needed to react with 57.5 mol Na:
2 moles of Na need → 1 mol of Cl₂, from the stichiometry.
57.5 moles of Na need → ??? mol of Cl₂.
<em>∴ The no. of moles of Cl₂ is needed to react with 57.5 mol Na =</em> (1 mol)(57.5 mol)/((2 mol) <em>= 28.75 mol.</em>
<em>∴ the mass of Cl₂ is needed to react with 57.5 mol Na = (no. of moles of Cl₂)(molar mass of Cl₂) =</em> (28.75 mol)(35.453 g/mol) <em>= 1019.27 g.</em>
The test is detecting the gas through its reaction with lime water and the result so that the limewater will turn milky/cloudy
You can wait until he either breaks up (if he does) or if just forget about him and go for another guy.
Answer: There is no question.
Explanation:
Due to no question I can simply not answer this. Pls mark me brianliest for answering correct.
