Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. ... Renewable resources are replenished naturally and over relatively short periods of time. The five major renewable energy resources are solar, wind, water (hydro), biomass, and geothermal.
Explanation:
Answer:
I am answering so the other guy can get brainliest: Renewable sources are sources that are *near-infinite (because the sun will eventually die one day) that are basically not depleted when used. Nonrenewable sources are sources that deplete when you use them, which are not easily replaceable. An example of a renewable resource is Solar Energy or Hydropower, a non-renewable source is fossil fuels or natural gas.

What is the total number of Joules lost when 10. grams of water at 80.°C is cooled to 60.°C?
Answer:
The total number of Joules lost to the surrounding is -837.2 J
Explanation:
Given that:
mass = 10 grams
initial temperature = 80°C
Final temperature = 60 °C
Specific heat of water= c = 4.186 J/g. °C
The total number of Joules lost can be determined by finding the amount of heat energy Q released by using the formula:
Q = mC ΔT
Q = 10 × 4.186 × (60 - 80)° C
Q = 10 × 4.186 × - 20° C
Q = -837.2 J
Thus, the total number of Joules lost to the surrounding is -837.2 J

What is Cough syrup?There is a non-opioid cough suppressant in this product (such as chlophedianol, dextromethorphan). It works on the cough center in the brain to help you stop coughing.
Moreover, this medicine contains an antihistamine, such as triprolidine, chlorpheniramine, or doxylamine, which blocks the effects of a natural chemical called histamine, which is responsible for allergy symptoms.
Before taking this medicine for a persistent cough brought on by smoking or a cough with excessively thick mucus, consult your doctor. The safety or effectiveness of cough-and-cold remedies in children under the age of 6 has not been established.
Therefore, Cough syrup nonprescription drug is commonly abused by teens.

If you are following the recipe for a cake, how will the order in which you add the ingredients affect the mass of the batter? (1 point)
A. It will have no effect because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.
B. If you add the liquid ingredients first, the final result will have less mass than if you added the dry ingredients first. This is because the dry ingredients will dissolve in the liquid ingredients.
C. If you add the dry ingredients first, the final result will have less mass than if you added the liquid ingredients first. This is because the dry ingredients will be dissolved by the liquid ingredients.
D. It will have no effect because heating an object never produces a chemical change and only chemical changes can create or destroy mass.
In cake, the ingredients have been changed to the baked cake, so the order of putting the ingredients has no effect on the mass of matter. Thus, option A is correct.
The baking of cake has been corresponds with the addition of the ingredients, thereby process mixing in order to create the reactant mixture that has been heated at the specific temperature for a specified time period. The resultant has been the baked cake matter.
The reagents and products all are matter, and baking has been the chemical reaction. According to the law of conservation of mass, matter cannot be created nor be destroyed in a chemical reaction; it can be changed from one form to another.
In cake, the ingredients have been changed to the baked cake, so the order of putting the ingredients has no effect on the mass of matter. Thus, option A is correct.
