Answer:

A. giant

Explanation:

Giant stars are older and hotter than dwarf stars. They can be thousands of times brighter than our Sun. They have low density (although they are large) as opposed to the white dwarf which is one of the celestial bodies with the highest density.

Among the giant stars we can mention the red giants and the blue giants.

The end of the lives of these stars is marked by explosive cosmic events, such as supernovae, which can give rise to black holes.

Calculate the mass of NaCO3 used in experiment. SHOW WORK — 15 points!!

Liono4ka [1.6K]

The mass of sodium bicarbonate (NaHCO₃) used in the experiment is 1.997 g

<h3>Calculating mass </h3>

From the question we are to calculate the mass of NaHCO₃ (sodium bicarbonate) used in the experiment

From the given information

Mass of empty evaporating dish = 46.233g

Mass of evaporating dish + Sodium bicarbonate = 48.230g

∴ Mass of sodium bicarbonate (NaHCO₃) = [Mass of evaporating dish + Sodium bicarbonate] - [Mass of empty evaporating dish]

Mass of sodium bicarbonate (NaHCO₃) = 48.230g - 46.233g

Mass of sodium bicarbonate (NaHCO₃) = 1.997 g

Hence, the mass of sodium bicarbonate (NaHCO₃) used in the experiment is 1.997 g

The symbol of the period five element that is a member of the pnicitides family

Zepler [3.9K]

The symbol of the period five element that is a member of the pnicitides family are antimony.

Explanation:

Pnictogen family

In periodic table, column 15 elements are Pnitogen family.
The pnictogen elements are Nitrogen-N, arsenic-As, phosphorus-P, bismuth-Bi, antimony-Sb, ununpentium-Uup.
There are five valence electrons each member of pnictogen family. In group 15 double bonds and triple bonds are formed due to these valence electrons.
Pnictides, binary compounds of group 15.

Antimony

Antimony is the element found in period 5 and block p.
A chemical element, Antimony (Sb) from Latin word stibium and 51 is its atomic number. It is in solid state.
In ancient times, antimony compounds are used as cosmetic and medicine.
Appeared as semi metal.
Electronic configurations of Sb is [Kr] 4d105s25p3.
