Answer:
Personally I think thatthr answer could be 5.38853503%, you can round it however you need.
Explanation:
There's a value of error between the noted square meters and the actual room's area. which is 4.23. Using the formula to get the percentage of error is getting the value (78.5 - 74.27 = 4.23) and dividing it by 78.5. Then just multiply it by 100 to get the percentage.
Answer:
Explanation:
Given:
A solution contains one or more of the following ions such as Ag, and
Here the Lithium bromide is added to the solution and no precipitate forms
Solution:
Since with LiBr no precipitation takes place therefore Ag+ is absent
Here on adding to it precipitation takes place.
Precipitate is as follows,
Thus,
is present
When is added again precipitation takes place.
Therefore the reaction is as follows,
Therefore,
are present in the solution
This can be seen in many ways depending on the situation at hand. Also the concern the counselor has for the problem is a key factor.
Its a cation because i am in chemistry right know
Answer: The new temperature of container is 123 K.
Explanation:
Given: = 795 mm Hg, = 273 K
= 358 mm Hg, = ?
Formula used to calculate the new temperature is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the new temperature of container is 123 K.
