<u>Answer:</u> The change in temperature is 84.7°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 1 kCal = 1000 Cal (Conversion factor: 1 kCal = 1000 Cal)
m = mass of steel = 100 g
c = specific heat capacity of steel = 0.118 Cal/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the change in temperature is 84.7°C
Answer:
i think this is a biology question but regardless a threatened species is same as endangered which is going to become extinct in the near future but i say the best answer is threatened with becoming extinct in the near future.
The best way to separate out a precipitate is using vacuum filtration. Use water to rinse out the flask thoroughly and wash the precipitate, followed by a quick rinse with ethanol to help dry it. After a few minutes on the vacuum pump, the precipitate should be ready to scrape off.<span> Also, centrifugation can be an option for small amounts especially if you just need the filtrate. For reasonable amounts, a Millipore setup or Gooch type crucible works nicely for quantitative analysis.</span>
The species bonds with the most ionic character is the compound with elements that develop the higher electronegativity difference between each other.
the most ionic character had maximum EN.
EN is max for SiO2
hope this help
