Answer:
Mg²⁺(aq) + SO₄²⁻(aq) + 2Na⁺(aq) + 2OH⁻(aq) → Mg²⁺(aq) + 2OH⁻(s) + 2Na⁺(aq) + SO₄²⁻(aq)
Explanation:
The complete ionic equation is the chemical equation where the chemical species in the aqueous phase (aq) are written as ions.
In the reaction:
MgSO₄(aq) + 2NaOH(aq) → Mg(OH)₂(s) + Na₂SO₄(aq)
MgSO₄ dissociates in Mg²⁺ and SO₄²⁻, NaOH in Na⁺ and OH⁻, Mg(OH)₂ doesn't dissociate because is as solid and NaSO₄ dissociates in Na⁺ and SO₄²⁻ ions.
That means the complete ionic equation is:
<h3>Mg²⁺(aq) + SO₄²⁻(aq) + 2Na⁺(aq) + 2OH⁻(aq) → Mg²⁺(aq) + 2OH⁻(s) + 2Na⁺(aq) + SO₄²⁻(aq)</h3>
Kinetic energy on mass. gravity, and speed
It decreases as temperature is indirectly proportional to volume
Answer:
The correct answer is a. mixing a heat killed pathogenic strain of bacteria with a living non pathogenic strain can convert some of the living cells into the pathogenic form.
Explanation:
Griffith proved that DNA is the genetic material in some organism.To do this he described the process of transformation in which the heat killed pathogenic bacteria when mixed with a non pathogenic bacteria can convert the non pathogenic strain into pathogenic one. This principle is called transformation.
The transformation of non pathogenic strain into pathogenic one occur due to the uptake of DNA of the heat killed pathogenic bacteria by the non pathogenic strain.
Answer:B. CO2
Explanation: It is B because it has both letters capitalized if it is a compound and it only has 1 letter capitalized if it is an element.
