Answer:
BaCl₂ and H₂SO₄
Explanation:
The reaction is the precipitation of BaSO₄ from solution.
This means that our reactants must contain the Ba ion and SO₄²⁻ ion. The reactants that meet this criteria are the; BaCl₂ aand H₂SO₄
The reaction is given as;
BaCl₂ + H₂SO₄ --> BaSO₄ + 2HCl
Answer:
we can use ratio to find the moles of NO first we have to make the balance equation
a)CO is the main air pollutant (b) All pollutants are not wastes (c) Water is polluted by dissolved oxygen (d) Lichens are pollution indicatorsnation:
I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.
Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>
Answer:
1.8 mol
Explanation:
concentration (M) = no. of moles (mol) ÷ volume (dm³)
no. of moles = concentration × volume
= 6 × 300 / 1000
= 1.8 mol
