Objects that look red are doing that.
Answer: the iris is the function of a pupil
Explanation:
Radiation: transferred energy
Convection: Transfer of heat
Conduction: transfer of electric charge
<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
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
