Answer:
Double replacement reaction.
It is in agreement with the law of conservation of mass because we have two potassium atoms, two iodine atoms, one lead atom, two nitrogen atoms and six oxygen atoms on both sides of the chemical equation (count them).
Explanation:
Hello there!
In this case, according to the given information, it turns possible for us to solve this problem by firstly considering that this reaction occurs between potassium iodide and lead (II) nitrate to yield potassium nitrate and lead (II) iodide which is clearly not balanced since we have one iodine atom on the reactants and two on the products, that is why the balance implies the placement of a coefficient of 2 in front of both KI and KNO3 as shown below:
Thus, we infer this is a double replacement reaction due to the exchange of both cations, K and Pb with both anions, I and NO3. Moreover, we can tell this balanced reaction is in agreement with the law of conservation of mass because we have two potassium atoms, two iodine atoms, one lead atom, two nitrogen atoms and six oxygen atoms on both sides of the chemical equation (count them).

Fossil fuels — coal, petroleum, and natural gas — are our main sources of energy, producing the vast majority of fuel, electricity, and heat used by people across the globe. In 2005 a whopping 86 percent of energy used worldwide came from fossil fuel combustion, and right now in the United States, the number isn’t much lower at about 85 percent. Unfortunately fossil fuels are also the primary culprit behind climate change. In the United States, they’re to blame for more than 80 percent of greenhouse gas emissions — and 98 percent of CO2 emissions alone. And while natural processes can absorb some of this CO2, an estimated 4.1 billion metric tons of it is added to our atmosphere each year. That number will rise dramatically if we don’t check ourselves.
Answer:
Conduct more trials.
Add less variables.
Choose a different person
Explanation:
More trials gives plenty of data to be examined.
Less variables makes for less confusion, and less things to keep track of.
Different person ensures that the experiment is not being done by one single person who could be messing up the data
Answer:
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
