Answer:
2. precipitate is formed
Explanation:
In this reaction barium nitrate and sodium sulfate solutions react to form a barium sulfate precipitate.Barium and sulfate ions will react to give barium sulfate precipitate where as the sodium and nitrate ions are spectator ions.
The net ionic equation after removing unchanged ions from each side of the full ionic equation will be;
Ba²⁺+ SO₄²⁻ → BaSO₄ (s)
<u>Answer:</u> The molarity of solution will be 0.049 M
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
We are given:
Given mass of sodium chloride = 10 g
Molar mass of sodium chloride = 58.44 g/mol
Volume of solution = 3.50 L
Putting values in above equation:
Hence, the molarity of solution will be 0.049 M
Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse.
The triangles are similar (right triangles which share an angle (A), so...
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2
Answer: 35.4 degrees
Explanation: because it cold
The cell membrane. The cell membrane controls what will leave and enter the cell, not only that but it also helps support and protect the cell.
