The answer you selected in the picture is correct!
Answer:
The temperature of the spatula is 80 ºC.
Explanation:
Heat transfer occurs when there is a temperature difference, in this case, if both temperatures in spatula and water are different. If there is no heat transfer between water and the spatula, then we conclude that temperature of the spatula is 80 ºC.
When particles collide with the surface of the solid.
Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.
