Name two elements that have the same properties as potassium (K)
I know one is calcium
Answer:
sodium and rubidium have the same properties with potassium. this is because sodium, potassium, and rubidium are in the same column that is they are all in group one of periodic table. all are alkali metals hence have the same properties.
Explanation:
The two elements that have the same properties as potassium ( K ) are sodium and rubidium.
What is element ?A chemical element is a species of atoms, including the pure material made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.
Fire, Earth, Water, and Air. Earth, water, air, and fire were the four elements that the ancient Greeks thought made up everything.
Potassium ( K ) and lithium ( Li ) are two elements that share qualities with sodium, since they belong to the same chemical family. The fact that potassium and sodium both have one valence electron and can produce +1 ions explains why their chemical characteristics are similar.
Thus, The two elements that have the same properties as potassium ( K ) are sodium and rubidium.

Which is a dominant trait that Mendel observed in pea plants?
bumpy pods
short height
yellow seeds
white flowers
A dominant trait that Mendel observed in pea plants are yellow seeds. Yellow seed color dominates over green seed color in peas. Green seeded plant crosses with heterozygous yellow seeded plant.
What is yellow seed ?A content strategy and development company called Yellow Seed works with a variety of brands, agencies, platforms, and formats.
Yellow is the dominant trait and green is recessive for seed color, whereas green is the dominant trait and yellow is recessive for fruit (pod) color. Question: A monohybrid cross was made by crossing a pea plant that produces yellow seeds with a pea plant that produces green seeds.
Either the green color seed trait or the yellow color seed trait is present in the parent plants. One of these features is often dominant over the other, meaning that it is always manifested when inherited. As a result of the dominant nature of the yellow seed color trait, all the progeny exhibit it.
Thus, A dominant trait that Mendel observed in pea plants are yellow seeds.

Explain how ocean currents affect climate
Long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward.
What is climate?Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of weather factors over a period of time that can range from a few months to many millions of years. Temperature, humidity, air pressure, wind, the precipitation are a few of the meteorological factors that are frequently measured.
Long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward. The evacuated warm water increases the air's temperature, whereas the cold water is cooled the air, as well as the land surface in which the blows.
Therefore, long-distance transportation of warmed or cooled water is possible with horizontal currents traveling northward or southward.

Which of the following best explains the Law of Conservation of Mass?
Group of answer choices:
A. In a chemical reaction the mass of the products is less than the reactants mass.
B. In a chemical reaction the mass of the products cannot be determined from the mass of the reactants.
C. In a chemical reaction mass of products always equals the mass of reactants.
D. In a chemical reaction the mass of the products is greater than the mass of reactants
Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
