Answer:
589.8 kJ/mol
Explanation:
Let's consider the process in which <em>the most loosely bound electron from each atom in a mole atom of gaseous calcium is removed.</em>
Ca(g) + Energy ⇒ Ca¹⁺(g) + 1 e⁻
The energy involved in this process is known as First Ionization Energy. The First Ionization Energy for calcium is 589.8 kJ/mol.
Answer:
D - A person's potential height is inherited, but they might not get enough nutrition to reach it.
Explanation:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

Suitable hypothesis for the experiment is as temperature increases rate of reaction also increases.
<h3>What is rate of reaction?</h3>
Rate of any reaction gives idea about the speed of the completion of that reaction.
Rate of reaction will be affected by many factors are some such factors are:
- Dependent variable: Rate of change of the chemical species which are present in the reaction is the dependent variables.
- Independent variable: Independent variable is temperature as it does not depends on the rate, in spite of this rate depends on temperature.
- Controlled variables: Environment of the reaction, amount of catalyst, light exposure to the reactions are the controlled variables as it depends on the requirement of the amount of product.
Hence, hypothesis is as temperature increases rate of reaction also increases.
