Weathering and erosion produce ever smaller rock particles which,
when mixed with dust and decayed organic matter over time ,
result in different types of soil .

Chemicals cancel each other out and produce a salt and water. A neutralization reaction my also occur
We are told that KOH is being used to completely neutral H₂SO₄ according to the following reaction:
KOH + H₂SO₄ → H₂O + KHSO₄
If KOH can completely neutralize H₂SO₄, then there must be an equal amount of moles of each as they are in a 1:1 ratio:
0.025 L x 0.150 mol/L = .00375 mol KOH
0.00375 mol KOH x 1 mole H₂SO₄/1 mole KOH = 0.00375 mol H₂SO₄
We are told we have 15 mL of H₂SO₄ initially, so now we can find the original concentration:
0.00375 mol / 0.015 L = 0.25 mol/L
The concentration of H₂SO₄ being neutralized is 0.25 M.
Answer:
The answer to your question is 1.013 Kg
Explanation:
TiCl₄ + 2Mg ⇒ 2MgCl₂ + Ti
mass of Mg = ?
mass of Ti = 1 kg
Process
1.- Calculate the molar mass of Magnesium and titanium (IV)
Mg = 24.3 g x 2 = 48.6 g
Ti = 48 g
2.- Write a proportion (rule of three)
48.6 g of Mg ------------- 48 g of Ti
x ------------- 1000 g of Ti
x = (1000 x 48.6) / 48
3.- Result
mass of Magnesium = 1012.5g
= 1.013 kg
