how many grams of silver medal could be recovered from a reaction of 50 g silver nitrate and copper metal

Chemistry
1 answer:
Likurg_2 [28]3 years ago
7 0

Answer:

Answer is: mass of copper is 127 grams.

Balanced chemical reaction: Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s).

m(Ag) = 432 g.

n(Ag) = m(Ag) ÷ M(Ag).

n(Ag) = 432 g ÷ 108 g/mol.

n(Ag) = 4 mol.

From chemical reaction: n(Ag) : n(Cu) = 2 : 1.

n(Cu) = 4 mol ÷ 2 = 2 mol.

m(Cu) = n(Cu) · M(Cu).

m(Cu) = 2 mol · 63.5 g/mol.

m(Cu) = 127 g

How many atoms of chlorine are in the carbon tetrachloride molecule?
zaharov [31]

Answer:

4 atoms of Chlorine

Explanation:

This is actually easy to explain,

First we have here a type of nomenclature. This one is the sistematic nomenclature, and begins by naming the number of atoms that one element has, beggining for the non metal first, and then the metal or the non metal acting like a metal. In this case, the Carbon is acting like a metal.

The number of atoms are named by a prefix of the number. Each number has a determined prefix. Here are some of them:

one = 1 = mono

two = 2 = bi or di

three = 3 = tri

Four = 4 = tetra

Five = 5 = penta

Six = 6 = Hexa

So tetrachloride, means that we have 4 atoms of chlorine in the molecule and the molecule is this one: CCl4

Moving molecules make things? heat up or cool down
Ksenya-84 [330]

Answer:

Heat up.

Explanation:

The faster molecules move the warmer an object becomes.

For example boiling water, when you boil water the water molecules will be moving extremely fast.

The slower molecules move, the colder an object is. For example an ice cube. All the molecules are only vibrating.

Hope this helps:)

Which of the following forms a molecular solid? Which of the following forms a molecular solid? C, graphite C10H22 CaO gold
Damm [24]

Answer:

C10H22

Explanation:

Molecular Solids comprises of a Vander waal's force of attraction between the molecule. These forces are very weak when compared to ionic and covalent bond.

In Carbon, Carbon is not a molecule but an atom. One of it unique characteristics is that it forms bonds with other carbon atoms. This property is know as catenation. The bond between these carbon atoms is know as covalent bond.

Graphite is an allotrope of carbon. It exists as black , slippery, hexagonal crystals.The carbon atoms in graphite forms flat layers and are joined together by strong covalent bonds. Graphite can be used as lubricant in engines.

Gold (Au) is an element on the periodic table with atomic number 79 and a mass number 197. It exists as a metal. Most times Gold forms hydrogen bonds.

C10H22 is known as decane. It is the tenth compound formed in the series of alkane family( an organic unsaturated carbon chain family). Alkanes are aliphatic hydrocarbons. The forces of attraction between the alkane family are weak.In decane , their exists Vander waal's force which makes Decane C10H22 a Molecular Solid.

Which substance is insoluble and floats in water? A) Ice shavings B) Wood shavings C) Salt crystals D) Sugar crystals
saw5 [17]
Answer: B) Wood Shavings

Reason/Explanation:
Notice what options A, C, and D have on common. Ice, salt and sugar. Those are all dissolvable. Insoluble means un-able to dissolve. It can't dissolve. Wood shavings can't dissolve in water. They will just float. Sugar, salt and ice will all dissolve. Wood shavings won't.
