What is the basic difference between series and parallel circuits?

1 answer:

8 0

In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

A rigid cylinder with a movable piston contains 50.0 liters of a gas at 30.0 degree C with a pressure of 1.00 atmosphere. What i

defon

Charles law states that volume of a gas is directly proportional to temperature at constant pressure for a fixed amount of gas. the pressure at given conditions is 1.00 atm and the standard pressure at STP conditions too is 1.00 atm therefore pressure remains constant.
V1/T1 = V2/T2
the parameters for the first instance are on the left side and parameters at STP are on the right side of the equation.
T1 - temperature in kelvin - 273 + 30.0 °C = 303 K
T2 - standard temperature - 273 K
V1 - volume - 50.0 L
substituting the values in the equation
50.0 L / 303 K = V / 273 K V = 45.0 L
answer is 2) 45.0 L

Toluene, C7H8, is used in the manufacture of explosives such as TNT (trinitrotoluene). A 1.500 g sample of liquid toluene was pl

dusya [7]

Answer:

There were 63.67 kJ liberated

If 1 mol of toluene was burned, there would be liberated 3906 kJ / mole

Explanation:

Step 1: Data given

Mass of the toluene sample = 1.500 grams

The temperature of the calorimeter rose from 25.000 °C to 26.413 °C

Write the balanced chemical equation for the reaction in the calorimeter.

C7H8(l) + 9O2(g) ⇒ 7CO2(g) + 4H2O(l)

Step 2: Calculate Q of the calorimeter

Q = C * Δt

Q = 45.06 kJ/ °C * ( 26.413 - 25)

Q = 63.67 kJ

Step 3: Calculate moles of toluene

Moles toluene = mass toluene / molar mass toluene

Moles toluene = 1.500 grams /92.14 g/mol

Moles toluene = 0.0163 moles

Step 4: Calculate energy per mole

energy per mole = 63.67 kJ / 0.0163 moles = 3906 kJ / mole

Answer:

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)

Explanation:

First, we will write the molecular equation, since it is easier to balance.

2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)

In the full ionic equation we include all ions and molecular species.

2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)

In the net ionic equation we include only the ions that participate in the reaction and the molecular species.

ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
