The endothermic reaction would be D. Batter becomes a pancake when heated. This is because the batter is absorbing the heat in order to turn into a pancake.
Answer is D. Batter becomes a pancake when heated.
Please vote brainliest thank you!
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
Reaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in concentration of the gas.
The correct should be A. thousands of galaxies
Galileo disproved the Ptolemaic theory, sanctioned for centuries by the Church, which held the Earth to be the central and principal object in the universe, about which all celestial objects orbited.
The answer should be answer B. More than three times the sun. I hope this helped! :)))
