find the molar mass of this

Answers

Explanation:

Given problem:

Find the molar mass of:

  SO₃ and C₁₀H₈

Solution:

The molar mass of a compound is the mass in grams of one mole of the substance.

To solve this, we are going to add the individual atomic masses of the elements in the compound;

  Atomic mass;

       S = 32g/mol; O = 16g/mol; C = 12g/mol and H = 1g/mol

For  SO₃;

     = 32 + 3(16)

     = 32 + 48

     = 80g/mol

For C₁₀H₈

      = 10(12) + 8(1)

      = 120 + 8

       = 128g/mol

Answers

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why

Answers

Answer:

ethanol

Explanation:

Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C

Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.

This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.

How are oxidation states of transition metals indicated in the names of metal
compounds?
A. Prefixes are used to indicate oxidation states.
B. Group numbers are used to indicate oxidation states.
C. Roman numerals are used to indicate oxidation states.
D. Subscripts are used to indicate oxidation states.

Answers

Answer:

The anser is c

Roman numerals are used to indicate oxidation states. Hence, option C is correct.

What is the oxidation state?

An oxidation state is a number given to the atom of an element when participating in a chemical reaction.

Roman numerals are used to indicate oxidation states of transition metals.

The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.

The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.

[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).

Hence, option C is correct.

Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.

A. Chemical energy - Sound energy - Electrical energy


O B. Electrical energy - Chemical energy - Sound energy


C. Chemical energy - Electrical energy - Sound energy


O D. Sound energy - Electrical energy - Chemical energy

Answers

Answer:

C. Chemical energy - Electrical energy - Sound energy

Explanation:

According to the law of conservation of energy, energy can be transformed i.e changed from one form to another. According to this question, a student builds an electrical circuit, which connects a battery to a siren. Based on this description, the electrical circuit uses ELECTRICAL ENERGY supplied by the CHEMICAL ENERGY in the battery cell.

The electrical energy in the circuit connects the CHEMICAL ENERGY in the battery to the siren, which makes the sound using SOUND ENERGY. In other words, the CHEMICAL ENERGY of the battery powers the ELECTRICAL ENERGY of the circuit to make SOUND ENERGY in the siren. Hence, the order of energy transformation is: Chemical energy - Electrical energy - Sound energy

Answer:

C. Chemical energy - Electrical energy - Sound energy

Tell me about one of these founding fathers: Benjamin Franklin, Thomas Jefferson, George Washington. (you pick the person) How can people stop being Homophobia? England Colonization1 Queen Elizabeth wanted to establish colonies in the Americas in order to grow the British Empire and to counter the Spanish, who had settled first in present-day St. Augustine, Florida (1565). The English hoped to find wealth, create new jobs, and establish trade ports along the coast of the Americas. The first successful English settlement was Jamestown, Virginia (1607). 2 Each colony, however, has its own unique history on how it was founded. Many of the colonies were founded by religious leaders or groups looking for religious freedom. These colonies included Pennsylvania, Massachusetts, Maryland, Rhode Island, and Connecticut. Other colonies were founded purely in hopes of creating new trade opportunities and profits for investors. Why did Colonists Come3 Many settlers came for better economic opportunities. Europe was really crowded and it was difficult to find a job. Families would also leave their fortunes to older sons which made younger siblings look somewhere else for money. Indentured Servants came and agreed to work for a family in exchange for a boat ticket.4 Many settlers came for religious freedom. The Protestant Reformation created hundreds of new religious groups and some religions became oppressed. The most famous group is the Pilgrims in Plymouth Rock (present-day Massachusetts, 1620). 5 However, many settlers were forced to come against their will. African slaves were kidnapped or traded in order to come to American and work. Many came and were forced to work on large plantations with no hope of freedom. Carolina Colony6 Initially given to Sir Robert Heath in 1629 by King Charles I, North and South Carolina were once one colony (Carolina). However, nothing was created from it. Eventually, Virginia settlers started moving South to present-day North Carolina in the late 1650s-early 1660s. The first permanent English settlers, Nathaniel Batts and George Durant, purchased land from the natives who lived in the Albemarle Region (present-day Northeastern N.C.) By the time the British king (Charles II) chartered it in 1663, hundreds of settlers were already living there. 7 King Charles II split up the Carolina colony among eight Lords Proprietors, men who helped him regain the throne after the English Civil War. The Lords Proprietors were required to collect taxes, or quit-rents, from the settlers in order to keep their share of the land. The problem? The settlers, who were used to living independently without paying taxes, refused to do this. 8 The tension over taxes and political power led to multiple conflicts between the settlers and Lords Proprietors colonial officials, including Culpepers Rebellion (1677). Continued conflicts over politics and religion, plus fighting with the natives (notably the Tuscarora War) split the colony into North and South Carolina in 1712. North Carolina became a royal colony in 1729, controlled by the king himself.Questions:Why did Queen Elizabeth I want to colonize the New World (Americas)?What were some of the reasons why English settlers wanted to come to the New World?Why were colonies like Massachusetts, Pennsylvania, Maryland, and Connecticut founded?Compare indentured servants and slaves coming to the New World.
