Which is the correct answer?
What is the total number of grams of solute in 500 milliliters of 1M CH3COOH (formula mass = 60)?
Answer:
30 grams
Explanation:
Molarity of a solution represents its molar concentration, and can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided, volume of solution = 500 milliliters, molarity = 1M
Volume of solution in liters = 500mL ÷ 1000 = 0.50L
Molarity = n/V
1 = n/0.50
n = 0.50moles
Using mole = mass/molar mass
Molar mass of CH3COOH (acetic acid) = 60g/mol
Mass = mole × molar mass
mass = 0.50 × 60
mass = 30 grams.

1- What is the molar mass of the following compounds?
a. Ca(OH) 2 _______________________________=
b. H 2 O 2 _______________________________=
c. KCl _______________________________=
d. NaH 2 PO_______________________________=
Answer:
a. Ca(OH)₂ = 74.08 g/mol
b. H₂O₂ = 34 g/mol
c. KCl = 74.55 g/mol
d. NaH₂PO₄ = 119.97 g/mol
Explanation:
In order to determine the molar mass of each compound we need to sum, the molar mass of each element.
a. Ca(OH)₂
40.08 g/mol (Ca) + 2 . 16 g/mol (O) + 2 . 1 g/mol (H) = 74.08 g/mol
b. H₂O₂ → 2 . 1 g/mol (H) + 2 . 16 g/mol (O) = 34 g/mol
c. KCl → 39.1 g/mol (K) + 35.45 g/mol (Cl) = 74.55 g/mol
d. NaH₂PO₄
23 g/mol (Na) + 2 . 1 g/mol (H) + 30.97 g/mol (P) + 4 . 16 g/mol (O) = 119.97 g/mol
What is a fault, and how does the existence of faults support the theory of plate tectonics?
“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

Ammonia, nh3, for fertilizer is made by causing hydrogen and nitrogen to react at high temperature and pressure. How many moles of ammonia can be made from 0.15 moles of nitrogen gas? _h2+_02 to _nh3
Answer:
[tex]0.30molNH_3[/tex]
Explanation:
Hello there!
In this case, since the reaction for the formation of ammonia is:
[tex]3H_2+N_2\rightarrow 2NH_3[/tex]
We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:
[tex]0.15molN_2*\frac{2molNH_3}{1molN_2}[/tex]
And the result is:
[tex]0.30molNH_3[/tex]

How many moles of copper are needed to react with sulfur to produce 0.25 moles of copper (i) sulfide according to the following reaction: 2 Cu + S = Cu2S
Answer:
0.5 mole
Explanation:
The equation for the reaction is given below:
2Cu + S —> Cu2S
We can calculate the mole of copper (Cu) needed to react with sulphur (S) to produce 0.25 mole of copper(I) sulfide (Cu2S) by doing the following:
From the balanced equation above,
2 moles of Cu reacted to produced 1 mole of Cu2S.
Therefore, Xmol of Cu will react to produce 0.25 mole of Cu2S i.e
Xmol of Cu = 2 x 0.25 = 0.5 mole
Therefore, 0.5 mole of copper (Cu) will react with sulphur (S) to produce 0.25 mole of copper(i)sulfide (Cu2S)

how much energy is required to heat up 100.0 grams of water from 0.000C to 60.00C?
Answer:
25,104
Explanation:
100.0 x 4.184 x 60.0 = 25,104
Energy required to heat up 100 grams of water(4.184J/g°C) from 0.000C to 60.00C is 25,104.
What is Thermodynamics?The science of thermodynamics examines the connections between heat, work, temperature, and energy. The rules of thermodynamics explain how energy moves inside a system and whether or not the system is capable of performing beneficial work on its surroundings. The heat needed to increase one gram of a substance's temperature by one degree Celsius is known as specific heat capacity.
Here,
The specific heat capacity of water is 4.184 J/g° C
This is the heat required to increase the temperature by 1°C.
same way, 4.186J is heat required to raise the temp of 1 gram of water.
Derived equation is: q = mcΔT
Where,
q is heat required
c is specific heat capacity of the substance
m is mass of the substance and
ΔT is the change in temperature
Given,
m = 100g
ΔT = 60.00C - 0.00C
ΔT = 60°C
c = 4.184 J/g°C
now, substitute the values:
q = mcΔT
q = 100 × 60 × 4.184
∵ q = 25,104
