Brut [27]

Answer:

William Shakespeare (bapt. 26 April 1564 – 23 April 1616)[a] was an English playwright, poet, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist.[2][3][4] He is often called England's national poet and the "Bard of Avon" (or simply "the Bard").[5][b] His extant works, including collaborations, consist of some 39 plays,[c] 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright.[7] They also continue to be studied and reinterpreted.

Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna and twins Hamnet and Judith. Sometime between 1585 and 1592, he began a successful career in London as an actor, writer, and part-owner of a playing company called the Lord Chamberlain's Men, later known as the

How much heat is required to raise the temperature of 65.8 grams of water from 31.5ºC to 46.9ºC?
vodomira [7]

Answer: 1,013.32 cal × 4.18 J/cal = 4,235.68 J

Explanation:

1) Data:

Water ⇒ C = 1 cal/g°C

m = 65.8 g

Ti = 31.5°C

Tf = 36.9°C

Heat, Q = ?

2) Formula:

Q = mCΔT

3) Calculations:

Q = 65.8g × 1 cal/g°C × (46.9°C - 31.5°C) = 1,013.2 cal

4) You can convert from calories to Joules using the conversion factor:

1 cal = 4.18 J

⇒ 1,013.32 cal × 4.18 J/cal = 4,235.68 J

All the following are acid ionization reactions except
kompoz [17]

A substance that reacts with certain metals to produce salts and releases hydrogen ions into water. Acids give certain dyes a reddish tint and have a sour flavor. Some body-produced acids, such as stomach acid, can support organ function. Hydrochloric acid is a kind of acid.

What is Ionization Reaction?

A neutral atom or molecule can become electrically charged atoms by obtaining or losing a free electron, which is the definition of ionisation. Ionization takes place during a chemical reaction. An atom or molecule must either lose or gain electrons in order to ionise; the electron that is gained or lost creates an ion. An anion is a negatively charged atom or molecule that has gained an electron.

The atom or molecule that gains a free electron but loses it becomes positively charged and is known as a cation. Energy is either released or gained during ionisation.
