Answer:
increases only slightly; large
explanation
Water has one of the highest specific heats of any known liquid. This means that the temperature of a water sample _only increase slightly_______ with the input of a __large______ amount of energy.
OD. A swing moving back and forth
Kinetic energy refers to the energy an object has while it is in motion. The swing is the only moving option.
The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.
<h3>How magnesium hydroxide is formed?</h3>
It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.
The chemical equation between magnesium and water is given below:
Mg + 2H₂O -----> Mg (OH)₂ + H₂
So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.

Answer:
a) First-order.
b) 0.013 min⁻¹
c) 53.3 min.
d) 0.0142M
Explanation:
Hello,
In this case, on the attached document, we can notice the corresponding plot for each possible order of reaction. Thus, we should remember that in zeroth-order we plot the concentration of the reactant (SO2Cl2 ) versus the time, in first-order the natural logarithm of the concentration of the reactant (SO2Cl2 ) versus the time and in second-order reactions the inverse of the concentration of the reactant (SO2Cl2 ) versus the time.
a) In such a way, we realize the best fit is exhibited by the first-order model which shows a straight line (R=1) which has a slope of -0.0013 and an intercept of -2.3025 (natural logarithm of 0.1 which corresponds to the initial concentration). Therefore, the reaction has a first-order kinetics.
b) Since the slope is -0.0013 (take two random values), the rate constant is 0.013 min⁻¹:
c) Half life for first-order kinetics is computed by:
d) Here, we compute the concentration via the integrated rate law once 1500 minutes have passed:
