Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another.
<h3>
Answer:</h3>
2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat
<h3>
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
Dendrites receive information from other sources while axons send information away from the neuron.
It would be water. Since the body is 60-75% water, it is important in chemical reactions within the body.
Answer: The option that represents the chemical properties of Hydrogen gas is A (It explodes with a flame.)
Explanation: Hydrogen gas is the lightest of all gases and the most abundant element in the universe. It's physical and chemical properties are the characteristics that distinguishes it from any other substance.
chemical properties of Hydrogen are the characteristics that determine how it will react with other substances or change from one substance to another. They include:
-It burns in air or oxygen to produce water.
-When mixed with air it can spontaneously explode by spark, flame or sunlight. I hope this helps. thanks.
