Muriatic acid, an industrial grade of concentrated HCl, is used to clean masonry and cement. Its concentration is 11.7 M.
harkovskaia [24]

The volume of Muriatic acid needed is 199ml.

<h3>What is concentration?</h3>
  • Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
  • Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.  
  • Any type of chemical mixture can be referred to by the term "concentration," however solutes and solvents in solutions are most usually mentioned.
  • There are different types of molar (quantity) concentration, including normal concentration and osmotic concentration.
<h3>How is concentration determined?</h3>
  • Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V.
  • To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

Zoe is frying eggs in a pan. The eggs cook because of _____ of heat. Zoe feels hot as she stands near the stove mostly because o
erica [24]

Answer:

1) conduction

2) Radiation

Explanation:

Conduction is a mode of heat transfer by which heat energy is transferred through a material, the average position of the particles of the material remaining the same.

Radiation is a process of heat transfer by which heat is transferred from a hotter to a cooler point without any intervening medium.

The pan used to fry the egg is a conductor of heat hence heat can pass through it by conduction thereby enabling the eggs to cook.

Heat can travel without an intervening medium hence Zoe feels hot near the stove. This ability of the heat to travel without an intervening medium is called radiation.
