How many moles of SO3 are in 2.4 x 1024 molecules of S03?

A fusion example is the combining of hydrogen isotopes. a. True b. False

solmaris [256]

This statement is true. The combining of hydrogen isotopes is indeed a fusion example. Fusion is the process of the combining two distinct entities and most fusion reactions combine hydrogen isotopes to come up with such product.

Nitroglycerin is a dangerous powerful explosive that violently decomposes when it is shaken or dropped. The Swedish chemist Alfr

pshichka [43]

Answer:

1. 2 C₃H₅N₃O₉(l) ⇒ 3 N₂(g) + 1/2 O₂(g) + 5 H₂O(g) + 6 CO₂(g)

2. 146 g of nitroglycerin.

Explanation:

1. Write a balanced chemical equation, including physical state symbols, for the decomposition of liquid nitroglycerin ( C₃H₅N₃O₉) into gaseous dinitrogen, gaseous dioxygen, gaseous water and gaseous carbon dioxide.

The equation is:

C₃H₅N₃O₉(l) ⇒ N₂(g) + O₂(g) + H₂O(g) + CO₂(g)

Since atomicities in nitroglycerin are odd, it is easier to balance this equation by multiplying this compound by 2. The balanced equation is:

2 C₃H₅N₃O₉(l) ⇒ 3 N₂(g) + 1/2 O₂(g) + 5 H₂O(g) + 6 CO₂(g)

2. Suppose 41.0L of carbon dioxide gas are produced by this reaction, at a temperature of −14.0°C and pressure of exactly 1 atm. Calculate the mass of nitroglycerin that must have reacted.

First, we have to find the moles of CO₂ using the ideal gas equation.

P.V = n . R . T

where,

P is the pressure

V is the volume

n is the number of moles

R is the ideal gas constant (0.08206atm.L/mol.K)

T is the absolute temperature (-14.0 °C + 273.15 = 259.2 K)

$P.V=n.R.T\\n=\frac{P.V}{R.T} =\frac{1atm . 41.0L}{(0.08206atm.L/mol.K).259.2K} =1.93mol$

According to the balanced equation, 6 moles of CO₂ are formed when 2 moles of C₃H₅N₃O₉ react. And the molar mass of nitroglycerin is 227 g/mol. Then, for 1.93 moles of CO₂:

$1.93mol(CO_{2}).\frac{2mol(nitroglycerin)}{6mol(CO_{2})} .\frac{227g(nitroglycerin)}{1mol(nitroglycerin)} =146g(nitroglycerin)$

8. Based on the formula, predict whether each of the following compounds is primarily ionic or primarily covalent. a. sodium iod

Lina20 [59]

primarily ionic include = sodium iodide( NaI) , calcium chloride ( CaCl2)

primarily covalent include - Ammonia (NH3) , Methane ( CH4) and

Glucose (C6H12O6)

Explanation

ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.

for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.

Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.

For example in NH3 3 pairs of electron are shared. to form covalent bond.

What is the phase of water at 0.25 atm and 0°C?

seropon [69]

D.) as you can tell the temperature is the x axis while pressure (atm) is the y axis, so therefore you’d find (0,0.25) which gives u solid because its not near water or gas

Using your knowledge of reactions and mechanisms, draw the mechanism for the formation of 2-methylpropene from 2-methyl-2-propan

BARSIC [14]

Answer:

Here's what I get

Explanation:

The reaction is an E1 elimination of an alcohol to form an alkene. It has three steps:

1. Protonation

The alcohol is protonated with aqueous sulfuric acid to convert it into a better leaving group.

2. Loss of the leaving group

A water molecule leaves in a unimolecular process to form a stable 3° carbocation.

3. Loss of an α-hydrogen

A water molecule removes an α-hydrogen, forming 2-methylpropene and regenerating the original hydronium ion.
