When an atom has an equal number of electrons and protons it has an equal number of negative charge (the electrons) and positive electric charges (the protons). The total electric charge of the atomic is therefore zero
The two
Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (
electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the
Nucleophilicity of nucleophile i.e. Alcohols.
Answer:
Answer in explanation
Explanation:
An atom of iron having an atomic number of 26 means there are 26 protons in the nucleus of the iron atom. This also means that for an electrically neutral atom of iron, there are 26 electrons orbiting the nucleus of the iron atom.
Factually, this also means that the atom iron occupies the position of the 26th element on the periodic table. Going forward, we can also say that the proton number of the iron element is 26.

Two Sections that contain nitrogen of a nucleotide that bond together to connect strands of DNA or RNA.
Explanation:
Answer:
The specific heat capacity is 0.67
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
The amount of heat that a body receives or transmits is determined by the following expression:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
This expression indicates that between heat and temperature there is a direct proportional relationship.
In this case:
- Q= 100 J
- c= ?
- m= 5 g
- ΔT= Tfinal - Tinitial= 40 °C - 10 °C= 30 °C
Replacing:
100 J= c*5 g* 30°C
Solving:
c= 0.67
<u><em>The specific heat capacity is 0.67 </em></u><u><em></em></u>
