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.

In this exercise we have to observe the axes of the graph to associate the values of X with those of Y that correspond to 0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1.
<h3>How to calculate the Cartesian plane?</h3>
Just draw two lines: one of them vertical, starting from the point until it finds the x axis; another horizontal, starting from the point until it meets the y-axis.
Then plotting the value of X on the graph we find the following for each value of X to Y:
- X= 0 ; Y= 0;
- X= 1 ; Y= 5;
- X= 2 ; Y= 5;
- X= 3 ; Y= -3;
- X= 4 ; Y= -5;
- X= 5 ; Y= -3;
- X= 6 ; Y= 2;
- X= 7 ; Y= 0;
- X= 8 ; Y= 0;
- X= 9 ; Y= -1;
- X= 10 ; Y= -2;
- X= 11 ; Y= 1;
- X= 12 ; Y= 1;
- X= 13 ; Y= -1;
- X= 14 ; Y= -1;
- X= 15 ; Y= -2;
- X= 16 ; Y= 2;
- X= 17 ; Y= 3;
- X= 18 ; Y= -1;

Answer:
No. If you're a dairy farmer, you need lots of land and room for the cows, as well as room for a farm. New York City doesn't have any room. In order to be a dairy farmer, you can't live in an Urban or Suburban area; you have to live in a rural area.
Hope this helps! :)
Answer:
Glucose moves with the concentration gradient from high to low concentration using a membrane protein.
Explanation:
Facilitated transport is a type of passive transport where the molecules move from region of high concentration to low concentration. Since they are moving along the concentration gradient, energy is not required for the process. But it does require some special membrane proteins hence the term "facilitated". The proteins are required for movement of large and polar molecules because even their diffusion is difficult through the non polar lipid layer of membrane.
Here, glucose is moving from high to low concentration so it's diffusion but it is using membrane protein because it is polar hence it is facilitated diffusion transport.
HOPE IT HELPS! :D
