Answer:
The classification is mentioned below for the particular topic.
Explanation:
- Whether we position 2 different beakers in such a single beaker through one clean edge of zinc-containing H₃Po₄ and another one with unflushed zinc.
- The zinc that was washed set to release hydrogen gas way quicker, unlike unventilated zinc.
⇒ 
- Since fresh zinc complicates the cycle since, as a comparison to polluted zinc, there was little contact with either the reaction.
Could be separated by distillation.
Answer:
There is 50.2 kJ heat need to heat 300 gram of water from 10° to 50°C
Explanation:
<u>Step 1: </u>Data given
mass of water = 300 grams
initial temperature = 10°C
final temperature = 50°C
Temperature rise = 50 °C - 10 °C = 40 °C
Specific heat capacity of water = 4.184 J/g °C
<u>Step 2:</u> Calculate the heat
Q = m*c*ΔT
Q = 300 grams * 4.184 J/g °C * (50°C - 10 °C)
Q = 50208 Joule = 50.2 kJ
There is 50.2 kJ heat need to heat 300 gram of water from 10° to 50°C
Answer:
Multiply 1.25 by 0.04 and divide the result obtained by 1,000
Explanation:
Since there is .04 oz in 1 gram, we take the 1.25 gram and multiply by .04.
Next, to convert per liter to per milliliter, we divide by 1,000.
