25:18 meaning for every 25 moles of oxygen there's 18 moles of water
This is what I would use. Hopefully this helps:)
I think this answer is D or C
Answer:
The specific heat capacity of a metal is 1.31 J/g°C = C
Explanation:
A classical excersise of calorimetry to apply this formula:
Q = m . C . ΔT
177.5 J = 15 g . C (34°C - 25°C)
177.5 J = 15g . 9°C . C
177.5 J /15g . 9°C = C
1.31 J/g°C = C
In regards to this question, there are no options given to choose from and this makes the question difficult to answer. I hope the answer i am giving is the one you were looking for. The compound Mg(OH)2 when stirred in water will not pass through a filter paper as it is bound to form a sediment. This sediment will get stuck in the filter paper.
