Answer:
Preparation and Standardization of 0.1 M Ferrous Ammonium...
Dissolve 40 g of ferrous ammonium sulfate in a previously cooled mixture of 40 ml of sulphuric acid and 200 ml of water.
Dilute with sufficient freshly boiled and cooled water to produce 1000 ml.
Standardize the solution in the following manner.
Explanation:
Explanation:
The given data is as follows.
Heat transfer coefficient (h) = 12
Plate temperature (
) = 
= 303 K
Steady state temperature (
) = ?
Hence, formula applied for steady state is as follows.
= 
Putting the given values into the above formula as follows.
=
= ![5.67 \times 10^{-8} \times [(30 + 273)^{4} - T^{4}_{2}]](https://tex.z-dn.net/?f=5.67%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%20%5B%2830%20%2B%20273%29%5E%7B4%7D%20-%20T%5E%7B4%7D_%7B2%7D%5D)
= 282.66 K
= (282.66 -273)
= 9.66
Thus, we can conclude that the steady state temperature will be 9.66 .
She will cover distance in 3 days and 16 hours .the time will be 3:15 am on the fourth day.
Convert 5.9 miles/hour to feet/hour there are 5,280 feet in a mile
total distance covered = 47500
distance = rate x time
now, time = 47500/5280
time = 88 hours
88 hours = 3 Days and 16 Hours.
now the time will be 3 :15 am on the fourth day.
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
The distance traveled divided by the time taken is the most popular formula for calculating average speed. The alternative formula is to add the initial and final speeds together, then divide by 2.

36 divided by 12 is 3. you need three times as much of the recipe to make 36 brownies. The answer is B
Answer:
However, various hydrogen isotopes, such as H-2, have one proton and one neutron; H-3 has one proton and two neutrons, etc. The sum of the protons and neutrons in an atom's nucleus is its atomic mass. Thus, the atomic mass of the H-2 isotope is two, the atomic mass of the H-3 isotope is three, and so forth.
