What is the name of this ether organic compound?
Answer:
1–ethoxybutane
Explanation:
In naming the above compound, the following must be observed:
1. The longest chain gives the root name of the compound.
2. The shorter chain is named as substituent together with the oxygen group as alkoxy.
3. Locate the position of the alkoxy group by giving it the lowest low count.
4. Combine the above to obtain the name of the compound.
Now we shall name the compound as follow:
1. The longest chain is carbon 4 i.e butane.
2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.
3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.
4. The name of the compound is:
1–ethoxybutane.
How many moles of ethane gas, C2H6(g), will occupy 15.0 L at 30 degrees Celsius and 5.0 atm?
Answer:
3 mol
Explanation:
Given data:
Volume of ethane = 15.0 L
Temperature = 30°C
Pressure = 5.0 atm
Number of moles of ethane = ?
Solution:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
30+273 = 303 K
5.0 atm × 15.0 L = n×0.0821 atm.L/ mol.K × 303 K
75 atm.L = n× 24.87 atm.L/ mol
n = 75 atm.L / 24.87 atm.L/ mol
n = 3 mol

a. 3.80 moles of oxygen are used up in the reaction. How many grams of water are produced?
b. How many grams of oxygen does it take to produce 90.6 grams of Carbon Dioxide?
Answer:
¹/3 C3H8(g) + ⁵/3 O2(g)
Explanation:
The coefficient before every molecule is representative of the number of moles. We can represent it in ration form so as to calculate the question;
C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(l) means;
For every 1 mole of C₃H₈(g) and 5 moles of O₂(g) produces 3 moles of CO₂(g) and 4 moles of H₂O(l).
Therefore to produce 1.00 mole of CO₂(g);
We represent it in ratio;
C₃H₈(g) : CO₂(g)
1 : 3

We can write:
5/4 = 3,8/x
Solving for x:
x = 3,04 mols of H2O
Calculating the H2O mass:
M H2O = 18 g/mol
n = m/M
Solving for m:
m = 54,72 g of water
****************************
Using the same, but with molar mass:
M CO2 = 44 g/mol => 3 x 44 = 132 g
M O2 = 32 g/mol => 5 x 32 = 160 g
160/132 = x/90,6
solving for x:
x = 109,82 g if CO2

A1(OH)3 + HNO3–> H2O + A1(NO3)3
when the equation above is correctly balanced the coefficient of H2O is
A:1
B:2
C:3
D:8
Answer:
3
Explanation:
The reaction expression is given as:
Al(OH)₃ + HNO₃ → H₂O + Al(NO₃)₃
To solve this problem, let us assign coefficient a,b,c and d to each specie;
aAl(OH)₃ + bHNO₃ → cH₂O + dAl(NO₃)₃
Conserving Al : a = d
O: 3a + 3b = c + 9d
H: 3a + b = 2c
N: b = 3d
let a = 1 , d = 1, b = 3 , c = 3
Multiply through by 3;
a = 1, b = 3, c = 3 and d = 1
Al(OH)₃ + 3HNO₃ → 3H₂O + Al(NO₃)₃
what three things might influence a slide when conditions are right?
Answer:
3
Explanation:
The three things that can affect a condition to enforce a slide is friction, weight, and slope of an area. Solutions that can make flow easily are those that can create less friction depending on the condition of an environment where it is present.

Watch the animation and identify the correct conditions for forming a hydrogen bond.
A. A hydrogen bond is equivalent to a covalent bond.
B. A hydrogen bond is possible with only certain hydrogen-containing compounds.
C. Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an N , O, or F atom.
D. The CH4 molecule exhibits hydrogen bonding.
E. A hydrogen atom acquires a partial positive charge when it is covalently bonded to an F atom.
Answer:
options B,C and E are correct conditions for forming hydrogen bonds.
Explanation:
In order for particles to stick together or shows certain characteristics, there must be a bond of attractions that is making them to be able to stay together. Some of these attractions are strong while some are weak. The kind of attraction that is being considered in this question is the hydrogen bonding which is considered as part of the weak forces of attractions.
In order for hydrogen bonds to occur, there must be hydrogen atoms [option B is correct] and a much more electronegative elements such as oxygen, Fluorine and Nitrogen. Hence, option C is correct.
Since the Fluorine or oxygen or nitrogen have much more electronegative properties than hydrogen, it causes a partial negative charge on Fluorine or oxygen or nitrogen and a partial positive charge on the Hydrogen. Thus, option E is correct.

What is the mass of .89 moles of lithium metal, used in laptop batteries?
The mass of lithium metal that is used in lithium batteries is 6.17 grams, this can be calculated by using number of moles formula.
Number of moles:It is defined as the ratio between mass and molar mass.
It is given by:
Number of moles = mass / Molar mass
What information do we have?
Number of moles= 0.89 moles
Molar mass of Lithium metal= 6.941 g/mol
To find:
Mass of Lithium metal=?
On substituting the values
n= m/M
0.89 = m/ 6.941
m= 0.89*6.941
m= 6.177 grams
Thus, the mass of lithium metal is 6.177 grams.

The density of mercury is 13.6 g/cm'. How many quarts does 83.0 g of Hg occupy? (1 L=1.06 qt)
Answer:
0.0064 qt
Explanation:
Given data:
Density of mercury = 13.6 g/cm³
Mass of mercury = 83.0 g
How many quarts mercury have = ?
Solution:
First of all we will calculate the volume in cm³.
d = m/v
13.6 g/cm³ = 83.0 g / volume
Volume = 83.0 g / 13.6 g/cm³
Volume = 6.1 cm³
cm³ to L:
6.1 cm³ × 1 L / 1000 cm³
0.0061 L
In quarts:
1 L = 1.06 qt
0.0061 L × 1.06 qt / 1 L
0.0064 qt
ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 2.4 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.
Answer:
0.57 moles (NH4)3PO4 (2 sig. figs.)
Explanation:
To quote, J.R.
"Note: liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.
H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O
Assuming that H3PO4 is not limiting, i.e. it is present in excess
1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"
