The relation between °C and °F is

°F=

5

9

(°C)+32

when °F=°C

∴°C=

5

9

°C+32

∴°C−

5

9

°C=32

∴−

5

4

°C=32

∴°C=−40°C

∴T=−40℃

∴ At −40℃, both the celcius and Fahrenheit scales show the same reading.

Write a balanced half-reaction describing the reduction of gaseous dichlorine to aqueous chloride anions.
Annette [7]

Answer:- Cl_2(g)+2e^-\rightarrow 2Cl^-(aq)

Explanations:- In reduction the electrons are accepted and so they are written on the reactant side. When an atom accepts electrons then it forms anion. Chlorine has 7 valence electrons and it needs one more electron to complete it's octet. Since, dichlorine has two Cl atoms and each Cl atom needs one more electron to complete it's octet, two electrons are accepted by dichorine to make aqueous chloride ion. For balancing the equation, there would be two chloride ions as the reactant side has two chlorine atoms.

Draw the structures of all monobromo derivatives of pentane, c5h11br, which contain a 4-carbon chain.
SVETLANKA909090 [29]

Two or more compounds that have same molecular formula but differ in the arrangement of atoms in molecule and thus posses different properties are known as isomers.

The molecular formula of pentane is C_5H_1_2 substituting one hydrogen from pentane with bromine results in the formation of monobromo derivatives of pentane having molecular formula, C_5H_1_1Br.

The structure of monobromo derivatives of pentane that is 1-bromopentane, 2-bromopentane, and 3-bromopentane and having molecular formula, C_5H_1_1Br is shown in the image.

The other two arrangements of monobromo derivatives of pentane that is 2-bromo-2-methylbutane and 2-bromo-3-methylbutane is shown in the image.

There are different structures of monobromo derivatives of pentane having molecular formula, C_5H_1_1Br which contain a 4-carbon chain are 1- bromo-2-methylbutane and 1-bromo-3-methylbutane shown in the image.

Why were colonists in new england angry at king james 2 abd governor edmund andros of new england?​
Pani-rosa [81]

His strict imposition of autocratic rule was supported by his appointment by the King, who otherwise was not directly involved.

Explanation:

Andros’ imposition of Episcopalian worship in the Old South Meeting house, Boston his vigorous enforcement of the Navigation Acts.

He had earned the enmity of the local populace by enforcing the restrictive Navigation Acts.

He had infuriated Puritans in Boston by promoting the Church of England, which was rejected by many Nonconformist New England colonists.

When news of the overthrow of James II (1688) reached Boston, the colonists revolted, deposing Andros and imprisoning him.

His requirement that landholders take out new land patents and his limitations upon town meetings and rights of local taxation all aroused sharp resentment in colonial America.

If you measure the mass of an unknown metal and it is 35.60 grams, and then measure the volume by water
ozzi

Answer:

The answer is

<h2>8.90 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 35.60 g

volume = 4 mL

The density of the metal is

density =  \frac{35.60}{4}  \\

We have the final answer as

<h3>8.90 g/mL</h3>

Hope this helps you
