The question is incomplete, the complete question is;

Use the chemical reaction to answer the question. ​CaCO3 → CO2 ​+ CaO A scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction shown. What is the total mass of the products?

A. 10 grams B. 15 grams C. 30 grams D. 60 grams  

When a scientist heats 30 grams of calcium carbonate (CaCO3) in the chemical reaction, the total mass of the products is 30 grams.

According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction.

The simple interpretation of this law is that the total mass of reactants should necessarily be the same as the total mass of products obtained in the reaction.

We had 30grams of Calcium Carbonate (CaCO3) reacting hence we must have a total mass of 30 grams of CaO and CO2 obtained after reaction.

what is the opportunity cost of attending technical school versus attending a 4-year college or university?
Vilka [71]

Opportunity cost is relevant in this situation. Your opportunity basically consists of the full amount of your college expenses plus the money you would've made when you have chosen to work instead of enrolling in school. <u>The opportunity cost of attending college is $260,000.</u>

The potential benefits that even a person, investor, or business forgo while choosing between two possibilities are known as opportunity costs. Opportunity costs can be easily disregarded since they are by nature invisible.

The opportunity cost would be the worth of what you forgo while making a decision among two or more choices. It's a basic principle that applies to both investing and daily life. The opportunity cost in investing would be the amount of cash you can lose by choosing one asset above another.

Some states let you retake it and give you a second chance m, if your country doesn't do that then you have higher chance to take more, every year you get to take one and it determines if you get credit or honors, you can also do community service to get you more points, that helps a lot too once you get to a higher grade you get more options and tests you can take for credits and honors, I wouldn't be that worried.:)
