Answer:</h3>
2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

Explanation:</h3>
- Balancing chemical equations involves putting coefficients on reactants and products.
- This results in an equal number of atoms of each element on either side of the equation.
- Balancing chemical equations ensures that the law of conservation of mass is obeyed.
- According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.
- Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.
- Therefore, the balanced equation would be;
2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat
Answer: A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons

Answer: Option (D) is the correct answer.
Explanation:
An electric circuit works well when all the connections are complete but if any of the connections in the circuit is loose or disconnected then it is possible that current will not flow from the circuit.
Therefore, when Jenna removed one of the clips on the battery then circuit becomes incomplete and as a result there will no flow of current.
Thus, we can conclude that the electrical energy would stop because the circuit is incomplete.
