When discussing the Arrhenius equation and chemical / enzyme kinetics, which of the following statements is incorrect ? A. A cat

alyst lowers the activation energy of a reaction B. A high activation energy signifies that the rate constant depends strongly on temperature C. A negative activation energy indicates that the rate increases as the temperature is raised D. The activation energy, the parameter Ea in the Arrhenius equation, is the minimum energy that a molecular encounter needs in order to result in a reaction E. If a reaction has zero activation energy, its rate is independent of temperature

why would it not be necessary to heat the air in the balloon as much if the air outside the balloon is colder?
RUDIKE [14]

Hot-air balloons float because the air caught inside the balloon is heated up by a burner, making it less dense than the air outside. As the burner heats the air, it expands and some of the air escapes; that's what makes it less dense

1. write the complete chemical symbol for the ion with 14 protons 15 neutrons and 18 electrons
motikmotik

Answer:

1.   Si^{-4}

2.  Co^{+2}

Explanation:

An ion is formed when an atom that is said to be neutral gains or losses electrons.

It is thought that a negative ion (anion) is produced as it gains electrons and a positive ion (cation) is formed when it loses an electron.

Atomic number is the total number of protons and electrons in a neutral atom.

From the information

Protons = 14

electron = 18

Net Charge = no of proton - no of electron

= 14 - 18 = -4

Mass number = 14 + 15 = 29

Thus, the chemical symbol = Si^{-4}

For ion with 27 proton, 32 neutrons and 25 electrons

Net charge = 27 - 25 = +2

Mass number = 27 + 32 = 59

Thus, the chemical symbol = Co^{+2}

If 14 moles of oxygen react with 14 moles of hydrogen to produce water, what is the
Leokris [45]
Hydrogen is the limiting reactant because when doing a stoichiometry equation for the reactants, hydrogen will be used completely by having a smaller yield and oxygen will be excess (7 moles to be exact)
