Akia is balancing the equation Na + H2O NaOH + H2. He tries to find the coefficients that will balance the equation.
Pepsi [2]
<h3><u>Answer;</u></h3>

A: by counting up each individual atom and make sure the atom numbers are the same in the reactants and the products

<h3><u>Explanation;</u></h3>
  • <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation. </u></em>Therefore, <em><u>the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, </u></em>that is the side of reactants and side of products.
  • Thus, <em><u>any chemical equation requires balancing to ensure that the number of atoms of each element is equal in both sides of the equation</u></em>. Balancing is a try and error process that ensures that the law of conservation of mass holds.
  • In this case, the balanced equation would be;                                               2Na +2H₂O → 2NaOH +H₂

Kyle has a mass of 54 kg and is jogging at a velocity of 3 m/s. What is Kyle’s kinetic energy?
marissa [1.9K]
Kinetic energy can be solved by using the following formula: Kinetic energy = (1/2)*m*v^2

Where:

m = mass = 54 kg
v = velocity = 3 m/s

Since we are already given the needed values in the problem, direct substitution will be done:

KE =  <span>(1/2)*m*v^2
</span>KE =  <span>(1/2) * 54 * (3)^2
</span>KE = 243 J
