Answer:
Look at the periodic table of elements
Explanation:
Group 1 is the most reactive and to the right
Group 18 is least reactive and all the way to the left. The rest are in between. The groups go vertical.
You'd be able to solve with this information youre welcome
Answer:
Initial volume of the container (V1) = 1.27 L (Approx)
Explanation:
Given:
Number of mol (n1) = 5.67 x 10⁻²
Number of mol (n2) = (5.67 +2.95) x 10⁻² = 8.62 x 10⁻²
New volume (V2) = 1.93 L
Find:
Initial volume of the container (V1)
Computation:
Using Avogadro's law
V1 / n1 = V2 / n2
V1 / 5.67 x 10⁻² = 1.93 / 8.62 x 10⁻²
V1 = 10.9431 / 8.62
Initial volume of the container (V1) = 1.2695
Initial volume of the container (V1) = 1.27 L (Approx)
Answer:
45 minutes about
Explanation:
i think because i have 7 periods with 45 minutes each
Answer:
Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous BaCl₂ and aqueous (NH₄)₂SO₄ are mixed in solution to form aqueous NH₄Cl and solid BaSO₄. This is a double displacement reaction.
BaCl₂(aq) + (NH₄)₂SO₄(aq) ⇒ 2 NH₄Cl(aq) + BaSO₄(s)
The complete ionic equation includes all the ions and insoluble species.
Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)
