<h3><u>Answer;</u></h3>

Decomposition of calcium carbonate

CaCO3(s) → CaO(s) + CO2(g)

<h3><u>Explanation;</u></h3>
  • <em><u>Decomposition reactions are types of reaction that occurs when a reactant is broken down into two or more products. </u></em>
  • Decomposition may either be thermal where heat is used to break a reactant or may be catalytic where a catalyst is used to break down a reactant to yield two or more substance, for example decomposition of hydrogen peroxide.
  • <em><u>All metal carbonates decompose to produce a metal oxide and carbon dioxide gas.</u></em>
  • <em><u>Calcium carbonate undergoes thermal decomposition to form calcium oxide and carbon dioxide. </u></em>
  • The equation will be;

CaCO3(s) → CaO(s) + CO2(g)

The equation is balanced as the number of atoms of each element are equal on both side.

A light bulb whose resistance is 240 ohms is connected to a 120 voltage source. What is the current through the bulb?
Sedaia [141]

Answer:

0.5A

Explanation:

Using R = \frac{V}{I},

R is the resistance (in Ohms)

V is the voltage (in V)

I is the current (in A)

240=\frac{120}{I}

I = 0.5A
