Answer:
165 g
Explanation:
Law of Conservation of Matter states that neither matter or energy is destroyed but instead transferred.
Since we need a total of 180 g, we need to subtract 15g of one of the products to find the missing amount:
180 g - 15 g = 165 g Cu produced
Answer:
2 K3(PO4) aq + 3NiBr2 aq -------- 6 KBr aq + Ni3(PO4)2 s
Explanation:
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances.
The molarity of the diluted solution : 1.1 M
<h3>Further explanation</h3>
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
Can be formulated :

M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = Molarity volume of the solution after dilution
M₁=5
V₁=0.75
V₂=3.5

Universal indicators are unsuitable for indicators because it has a range of colors.
basically, it changes from pink in alkali to colorless acid.
