Name three stars that are hotter than the sun

1 answer:

7 0

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.

The proper name for a carbohydrate polymer with 2 subunits is

valentina_108 [34]

Carbohydrates are classified in three major categories depending upon the number of sub units joining to form them. These are,

Monosaccharides

Oligosaccharides

Polysachharides

The simplest single units are monosaccharides, if units are ranging between two and twenty they are called oligosaccharides and above twenty joining units they are called polysachharides.

Result:
The proper name for a carbohydrate polymer with 2 subunits is called Oligosachharide in general and Disaccharide in specific.

Answer ASAP 25 points

Answer: The correct answer is $NH_3$ is the base and $NH_4Cl$ is the salt.

Explanation:

Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce salt and water as products.

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and a base is defined as a substance which accepts protons.

For the given chemical reaction:

$NH_3+HCl\rightarrow NH_4Cl$

Here, $NH_3$ is a base because it is accepting proton and HCl is an acid because it is loosing proton.

$NH_4Cl$ is considered as a salt because it is formed by the combination of acid and base.

Hence, the correct answer is $NH_3$ is the base and $NH_4Cl$ is the salt.
