Answer: The correct answer is option d.

Explanation: Energy stored into gasoline is converted into another form of energy. This was very well explained on the basis of Law of conservation of energy. This law states that energy is conserved in the system which means that energy is converted from one form to another form.

The energy stored into gasoline is converted into mechanical energy which helps the car to move and some of the energy is lost in the form of heat.

Hence, the correct answer is Option d.

A sample of gas at 313 K and 4.95 atm occupies 85.62 L of space. Which
Daniel [21]

Answer: 85.62 L represents volume (V).

Explanation:

Volume is defined as the amount or quantity of a given substance or an object.

According to ideal gas equation:

PV=nRT

P = pressure of gas = 4.95 atm

V = Volume of gas = 85.62 L

n = number of moles

R = gas constant =0.0821Latm/Kmol

T =temperature =313K

Thus 85.62 L represents volume (V).

zhuklara [117]
LiAlH₄ is used as strong reducing agent. The hydride produced acts as a nucleophile and attacks the electrophillic carbon of carbonyl group. In given example two reactions are observed.

Reaction 1:
                 In first step LiAlH₄ when treated with Ester produces corresponding Aldehyde and alcohol.

Reaction 2:
                This aldehyde produced further reacts with LiAlH₄ to give a reduced product (Alcohols). In this case Butanol is produced.

The reaction schemes are shown as felow,

How to solve a balanced equation
geniusboy [140]

Explanation:

To balance a chemical equation, there are so many approaches to solve the problem.

A balanced chemical equation is one that obeys the law of conservation of matter.

According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".

This implies implies that equal number of atoms must be on both sides of the equation.

      There are two main approaches to balancing chemical equation;

  • Inspection
  • mathematical equation

We can inspect the equation and affix the proper coefficients to combining species.

Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:

 For example:

          H₂     +      O₂    →     H₂O

mathematically;

           aH₂     +      bO₂    →     cH₂O

  conserving:

         H :   2a  =  2c

         O:    2b  = c

 let a = 1

      c = 1

      b = \frac{1}{2}

multiply by 2 to give;

   a = 2, b = 1 , c= 2

               2H₂     +      O₂    →     2H₂O

Coal can be converted to methane gas by a process called coal gasification. The equation for the reaction is the following: 2 C
zloy xaker [14]

Answer:

24 g of C are needed to produce 1mol of CH₄

Explanation:

The reaction is:

2C (s) +  2H2O (l) → CH4(g) + CO2 (g)

2 moles of carbon react with 2 moles of water in order to produce 1 mol of methane and 1 mol of carbon dioxide.

If we want to produce 1 mol of methane, we need 2 moles of C

Let's find out the mass → 2 mol . 12 g/1 mol = 24g
