I think the correct answer from the choices listed above is option A. The key characteristic by which Dmitri Mendeleev arranged his periodic table was that the elements are arranged in increasing atomic number. Hope this answers the question.
Answer:
3.37kg of NaCl is the salt content of the dead sea
Explanation:
A concentration of 33.7% means there are 33.7g of NaCl in 100mL of solution.
To solve this question we need to convert 10.0L to mililiters, and then, solve for the mass of NaCl in grams and convert it to kg:
<em>Volume in milliliters:</em>
10.0L * (1000mL / 1L) = 10000mL
<em>Mass of NaCl:</em>
10000mL * (33.7g NaCl / 100mL) = 3370g NaCl
<em>In kg:</em>
3370g * (1kg / 1000g) =
<h3>3.37kg of NaCl is the salt content of the dead sea</h3>
Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.
Explanation:
- Rocks carried by the river smash together and break into smaller pieces. This process is called attrition.
- attrition is a form of coastal or river erosion, Attrition is an erosional process where rocks and pebbles are carried in the flow of a river.
- Abrasion occurs when the breaking waves which contain sand and larger pieces erode the shoreline or headland of the shore.
- When the rocks continue to collide with each other,they erode more and more, getting smaller and smaller until they are only sediment, this is when rocks that the sea is carrying
- The amount of attrition depends upon the number of factors: particle properties such as its size, shape, surface, hardness, and cracks.
- It also have environmental properties such as time, velocity, pressure, shear, and temperature.
Answer is 4 ½ billion.
Scientists think the earth's age is 4 ½ billion. This calculation is based on the radioactive dating. Since the formation of the earth, the time period has been divided into 3 major geological time periods as eon. They are phanerozoic, proterozoic and archean.
