Answer;

The balanced equation will be;

2C4H10 + 13O2 -> 8CO2 + 10H2O

Explanation;

-According to the law of conservation of mass , in each chemical equation the mass should be conserved, therefore the number of atoms of each element should be equal on the side of reactants and that of products, this is done by balancing the chemical equation.

-Therefore, to balance the above chemical equation, we will put a coefficient of 2 on C4H10, a coefficient of 13 on O2, a coefficient of 8 on CO2 and a coefficient of 10 on H2O. By so doing the equation will be balanced since the number of atoms of each element are equal on either side. We obtain;

2C4H10 + 13O2 -> 8CO2 + 10H2O

What is an atomic reaction​
castortr0y [4]

Atomic reaction is nothing but the reaction of one atom with the other atom to form the new compound.

<u>Explanation:</u>

  • The atom is considered as the ultimate basic particle of the matter.  
  • This atom comprise of electron neutrons and protons.
  • Generally in the atomic reaction, there will be loss or gain of the electron to or from the substance with which the reaction takes place.
  • In default, all atoms wanted to attain the noble gas configuration which is stable in nature. These atoms from the ionic or covalent bond by sharing the electron.

What particle decay is this? 210 83 Bi→210 84 Po ​
sesenic [268]

Answer:

Beta emission

Explanation:

In beta emission, a neutron is converted into a proton thereby emitting an electron and a neutrino. A neutrino is a particle that serves to balance the spins.

When a nucleus undergoes beta emission, the mass number of the parent and daughter nuclei remain the same while the atomic number of the daughter nucleus is greater than that of its parent by one unit.

Hence, in beta emission, the daughter nucleus is found one pace to the right of the parent in the periodic table.

At 1.00 atmosphere pressure, a certain mass of a gas has a temperature of 100oC. What will be the temperature at 1.13 atmosphere
Inessa [10]

Answer:  Final temperature of the gas will be 330 K.

Explanation:

Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T     (At constant volume and number of moles)

{P_1\times T_1}={P_2\times T_2}

where,

P_1 = initial pressure of gas   = 1.00 atm

P_2 = final pressure of gas  = 1.13 atm

T_1 = initial temperature of gas  = 100^0C=(100+273)K=373K K

T_2 = final temperature of gas  = ?

{1.00\times 373}={1.13\times T_2}

T_2=330K

Therefore, the final temperature of the gas will be 330 K.

Given the partial equation: NO3− Pb2 → NO2 Pb4 , balance the reaction in acidic solution using the half-reaction method and fill
Fed [463]

Answer : The balanced reaction in acidic solution is,

2NO_3^-+1Pb^{2+}+4H^+\rightarrow 2NO_2+1Pb^{4+}+2H_2O

Explanation :

The given partial equation is,

NO_3^-+Pb^{2+}\rightarrow NO_2+Pb^{4+}

First we have to separate into half reaction. The two half reactions are:

NO_3^-\rightarrow NO_2

Pb^{2+}\rightarrow Pb^{4+}

Now we have to balance the half reactions in acidic medium, we get:

NO_3^-+2H^++1e^-\rightarrow NO_2+H_2O       ............(1)

Pb^{2+}\rightarrow Pb^{4+}+2e^-     ............(2)

Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get

2NO_3^-+4H^++2e^-\rightarrow 2NO_2+2H_2O  ...........(3)

Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.

2NO_3^-+1Pb^{2+}+4H^+\rightarrow 2NO_2+1Pb^{4+}+2H_2O
