Explanation:

A chemical reaction is one in which a chemical change occurs.

During a chemical change;

  • The process is irreversible
  • New kinds of matter produced
  • There is a change in mass

Based on these premise;

 Baking  cake batter is a chemical reaction because you cannot reverse the process

  Shredding a paper is not a chemical reaction because no new kind of matter is produced.

  Twisting of a metal wire is not a chemical reaction

   Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed

Write balanced nuclear equations for the following:(a) β⁻ decay of silicon-32
S_A_V [24]

The balanced nuclear equations for the following:(a) β⁻ decay of silicon-32 is (27,14)Si -> (0,-1)beta + (27,15)P

<h3>What is balanced nuclear equation?</h3>

A nuclear reaction is generally expressed by a nuclear equation, which has the general form, where T is the target nucleus, B is the bombarding particle, R is the residual product nucleus, and E is the ejected particle, and Ai and Zi (where I = 1, 2, 3, 4) are the mass number and atomic number, respectively. Finding a well balanced equation is critical for understanding nuclear reactions. Balanced nuclear equations provide excellent information about the energy released in nuclear reactions. Balancing the nuclear equation requires equating the total atomic number as well as the total mass number before and after the reaction using the rules of atomic number and mass number conservation in a nuclear reaction.
