D, because soluability is a physical property
3KI + HClO + HCl = 2KCl + K[I₃] + H₂O
10FeSO₄ + 2KMnO₄ + 8H₂SO₄ = 5Fe₂(SO₄)₃ + 2MnSO₄ + K₂SO₄ + 8H₂O
The house wiring should be done parallel because, in parallel connection there will be more advantages than a series connection.
Let a house is wired in series and it contains a fan, tube light, TV, refrigerator. All the devices are connected in series. Now, due to some disturbance the fan speed working or it burned. Then since the connection was a series, due to one appliance failure causes the whole circuit to fail. If it is burned that means it making an open circiut. Then there will be no current flow in the circuit.
Now if it was a parallel connection as we know already, the parallel connection is nothing but individual appliances connected to the same line by tappings. That means there's no dependency of one appliance on another. So if an appliance fail or burns it doesn't effects the remaining appliances. And there will be uninterrupted supply to the healthy appliances can be achieved.
That’s why we use parallel for house wiring
<u>Answer:</u> The density of HCl solution is 1.18 g/mL
<u>Explanation:</u>
We are given:
Mass of beaker = 5.333 g
Mass of HCl + beaker = 11.229 g
Mass of HCl = [11.229 - 5.333] g = 5.896 g
To calculate the density of substance, we use the equation:
Mass of HCl = 5.896 g
Volume of HCl = 5.00 mL
Putting values in above equation, we get:
Hence, the density of HCl solution is 1.18 g/mL
1. opposite
2. positive
3. negative
