Sodium Chloride also known as table salt, the sodium has a positive charge and the chloride a negative so after ionization that leaves you with two negative charges because it takes the salt away. possibly disforming the atoms.<span />
Metals :-
Group 1A - Alkali metals ( highly reactive metals)
Non-metals :-
Group 17 - Halogens ( highly reactive non-metals )
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield
actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)
(56,9 x100)/36,6=
= 155%
Answer:
Acidic conditions
Explanation:
From the equations, it is clear that addition of acid favours the precipitation of calcium oxalate. As acid is added, the equilibrium position continues to shift to the far right, favouring the complete dissociation of the oxalic acid. This decreases the pH of the solution by increasing oxonium ion concentration.
Similarly, as the oxalate ion concentration increases, the precipitation of the calcium oxalate is favoured at low pH. Hence the answer.
Answer:
Melting ice causes more warming.
Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.
