Answer:
The bronsted- Lowry acid is H₂PO₄⁻
Explanation:
Bronsted-Lowry acid donates a proton (H⁺)
H₂PO₄⁻ + OH⁻ → HPO₄²⁻ + H₂O
In the reaction above, H₂PO₄⁻ is donating the proton to OH⁻ resulting in H₂O and the deprotonated species. This makes it a bronsted-Lowry acid.
The two elements occur in nature as liquids are bromine and mercury.
Answer:
Landform: MID-OCEAN RIDGE Plate Boundary: DIVERGENT Type of Plates: 2 Oceanic Plates (OP) pull apart How is it formed? Two oceanic plates (OP) move away from each other, allowing magma to rise up from inside the Earth. The magma reaches the bottom of the ocean, turns in to lava and cools (forming new rock)
Explanation:
Answer: The ΔH of the reaction if 51.3 g of 
reacts with excess 
to yield 1387.6 kJ is 432.27kJ
Explanation:
To calculate the moles, we use the equation:
moles of
As is present in excess, is the limiting reagent as it limits the formation of product.
If 3.21 moles of methane releases heat = 1387.6 kJ
Thus 1 mole of methane release=
When the protons and neutrons combine to form a nucleus, the mass that disappears
