Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present
Answer:
The protons inside an atom's nucleus help bind the nucleus together. They also attract the negatively charged electrons, and keep them in orbit around the nucleus. The number of protons in an atom's nucleus determines which chemical element it is.
Answer:
We are in Tropical Rainforests.
Explanation:
Biome is basically an ecological region of earth that has specific type of flora and fauna (plants and animals). Every biome has specific abiotic factors like specific climate, temperature, geology, vegetation, soils and relief.
There are total 8 biomes in the world
- Desert
- Grassland
- Temperate Boreal Forest
- Chaparral
- Tropical Savanna
- Tropical Rainforest
- Tundra
- Temperate Deciduous Forest
Now in our question, we have been given some conditions and are asked to identify the biome. The annual precipitation is about 300 cm and the average temperature is around 25 degrees Celsius.
Now, if we study the characteristics of all these biomes, it is very simple to identify that the biome is Tropical Rainforest.
Important characteristics of Tropical Rainforest:
- They receive more than 200 cm of rain each year.
- The temperature of the biome is between 20 degree Celsius and 25 degree Celsius during the whole year.
- Around 50 percent of the animal specie of the world are found here.

Answer:
The chemical formula for ammonium hypochlorite is NH4ClO.
The chemical formula for ammonium nitrate is NH4NO3.
Explanation:
These two are correct
Plant cells<span> are </span>eukaryotic cells<span>. Prokaryotic </span>cells<span> do not contain a membrane bound nucleus, mitochondria or other membrane bound </span>cell<span> structures (organelles), the DNA of prokaryotic </span>cells<span> are located in the cytoplasm of the </span>cell<span>. ... </span>Plant cells<span> are </span>eukaryotic<span> because they have a nuclear membrane.
so therefore, A rose thorn is a eukaryotic plant cell.</span>
