potassium reacts the most vigorously.
Answer:
V = 56.72 L
Explanation:
Given data:
Number of mole of neon gas = 0.83 mol
Temperature = 35°C
Pressure = 0.37 atm
Volume of gas = ?
Solution;
Temperature = 35°C (35+273 =308K)
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
Now we will put the values in formula.
V = nRT/P
V = 0.83 mol ×0.0821 atm.L/mol.K ×308K / 0.37 atm
V = 20.99 L/ 0.37
V = 56.72 L
Explanation:
Bella is right
Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Answer:
A. Erosion
Explanation:
Erosion is the process in which soil and rock are worn away and transported by wind or water and transported to another location.
The image below shows how water has eroded a coastline.
B is wrong. Chemical weathering is the disintegration of rocks by reactions with water and the acids dissolved in it
C is wrong. Deposition is the process in which sediments carried by wind, water or ice are deposited at another location.
D is wrong. Physical weathering is the breakdown of rocks and soil by physical processes like the freezing of ice in the cracks of rocks.
Answer:
physical projects
Journal entries
Materials
Lab reports
Artworks
Explanation:
Definition of a Portfolio:
Portfolio can be defined as a physical collection of student work that includes materials such as written assignments, completed tests, artwork, lab reports, physical projects and other material evidence of learning progress and academic accomplishment, including awards and honors,
A portfolio is a long-term form of self reflection and assessment that students do together.
Portfolios are a great way to demonstrate the competencies you would list on a resume or talk about in a science interview
