The surface area would be 25cm, while the vloume would be
or length×width×height
125cm cubed
Since you did not give the reactions, i cannot give the answers.
In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron rich nucleophile selectively bonds with or attacks the positive or partially positive (+ve)charge of an atom or a group of atoms to replace a leaving group; the positive or partially positive atom is referred to as an electrophile. The whole molecular entity of which the electrophile and the leaving group are part is usually called the substrate.
The most general form for the reaction may be given as the following:
<span>Nuc: + R-LG → R-Nuc + LG<span>:</span></span>
A. The potential energy from the batteries in the torch is transferred to the filament of the bulb. The energy is transferred to the surroundings as thermal energy and light. Most of the energy is transferred as thermal energy which is not useful and only some of the energy is transferred as light
Answer:
Chlorine-36 undergoes β-decay.
Explanation:
Cl-36 is radioactive. It emits an electron ( a β-particle) to become more stable and forms Ar-36.
The nuclear equation is
<h3>
Answer:</h3>
#1. Type of reaction: Single displacement
#2. Balanced equation: Zn + 2HCI → ZnCI₂ + H₂
<h3>
Explanation:</h3>
<u>We are given;</u>
- The equation; Zn+HCI → ZnCI₂ + H₂
Assuming we are required to identify the type of reaction and balance it;
- The reaction is a <u>single displacement reaction.</u>
- Zinc metal displaces hydrogen atom from hydrochloric acid to form a salt, zinc chloride and hydrogen gas.
- To balance the equation, we put coefficients on the reactants and products for the number of atoms of each element to be equal on both sides of the equation.
- In this case, the appropriate coefficients are 1, 2, 1 and 1
- Therefore, the balanced equation will be;
Zn + 2HCI → ZnCI₂ + H₂
