Explanation:

Gold has a specific gravity of almost 20. A 5-gallon bucket of water weighs 40 pounds. A 5-gallon bucket of gold would weigh around 800 pounds.
To determine how much a 5-gallon bucket of gold would weigh, we need to consider the specific gravity of gold. Specific gravity is a measure of the density of a substance compared to the density of water. Gold has a specific gravity of almost 20, which means it is approximately 20 times denser than water.
We know that a 5-gallon bucket of water weighs 40 pounds. Since gold is 20 times denser than water, a 5-gallon bucket of gold would weigh 20 times more than a 5-gallon bucket of water. Therefore, the weight of a 5-gallon bucket of gold can be calculated as follows:
40 pounds x 20 = 800 poundsBased on this analysis, a 5-gallon bucket of gold would weigh approximately 800 pounds.

Avogadro's NumberAvogadro's number is the number of particles in one mole of substance. 6.022 × 10²³ is known as Avogadro's constant / Avogadro's number.
Avogadro's number = 6.022 × 10²³
How to find the number of atoms ?
Number of atoms = Number of moles × Avogadro's Number
= 8.0 × 10⁻⁶ × 6.022 × 10²³
= 48.176 × 10¹⁷ atoms of boron
Thus, from the above conclusion we can say that 48.176 × 10¹⁷ atoms of boron are present in 8.0 × 10⁻⁶ moles of boron.

For the reaction: 2H2O → 2H2 O2, what is the total number of moles of O2 produced from the complete decomposition of 8 moles H2O?.
The complete dissociation of 8 moles of water produces 4 moles of oxygen.
The moles of reactants and products in the chemical reaction corresponds to the whole number representation of the stoichiometric coefficient in the balanced chemical equation.
Computation for moles of oxygen producedThe balanced chemical equation for the reaction is:
[tex]\rm 2\;H_2O\;\to\;2\;H_2\;+\;O_2[/tex]
From the balanced chemical equation, dissociation of 2 moles of water produces 1 mole of oxygen.
The moles of oxygen produced by 8 moles of water are:
[tex]\rm 2\;mol\;H_2O=1\;mol\;O_2\\\\8\;mol\;H_2O=\dfrac{1}{2}\;\times\;8\;mol\;O_2\\\\ 8\;mol\;H_2O=4\;mol\;O_2[/tex]

how much heat is required to raise the temperature of a 5.45-g sample of iron (specific heat = 0.450 j/g°c) from 25.0°c to 79.8°c?
Answer:
134.397 Joules
Explanation:
Using the formula:
E = C × m × Δθ (where E is Energy, C is specific heat capacity and Δθ is change in temperature)
So E = 0.45×5.45×(79.8-25)
So E = 134.397 Joules
The heat required to raise the temperature of 5.45g of iron is equal to 134.4 J.
What is the specific heat capacity?The specific heat capacity is described as the quantity of heat required to raise the temperature of one unit of substance by one-degree Celsius. The specific heat capacity of the substance depends upon the nature of the substance, not its quantity.
The mathematical formula can be used to determine the specific heat is equal to:
Q = m×C×ΔT
Given, the mass of the sample of iron, m = 5.45 g
The initial temperature of the sample, T₁ = 25°C
The final temperature of the sample, T₂ = 79.8°C
The specific heat capacity of iron, C = 0.450 J/g.°C
The heat required for the sample of iron will be:
Q = 5.45 × (0.450) × (79.8 -25)
Q = 134.4 J
Therefore, the heat required to raise the temperature of a 5.45g sample of iron is 134.4 J.

what is a matter and how do it work?
Answer:
Matter is any substance that has mass and takes up space. Any physical object consists of matter. It doesn't matter whether it's an atom, element, compound, or mixture. It's all matter. (Not a pun, i promise ツ)
However, unlike some believe, not everything you encounter in the world is matter. Matter can be converted into energy, which has neither mass nor volume. So, light, sound, and heat are not matter. Most objects have both matter and some form of energy, so the distinction can be tricky. For example, a candle flame certainly emits energy (light and heat), but it also contains gasses and soot, so it is still matter. The building blocks of matter are called "atoms" and "molecules." They, too, are matter. The matter we can detect normally is called "baryonic" matter. However, there is another type of matter out there, which can't be directly detected. But its influence can. It's called dark matter.
Attached below is a picture of examples of matter.

how to find percent composition of a compound composed of 16.2 grams of calcium and 28.8 grams of chlorine
This problem is providing us with the mass of calcium and chlorine. Thus, the percent composition of each element in the compound is required and found to be 36 % for calcium and 64 % for chlorine, according to the following:
Percent compositions:In chemistry, we can use percent compositions in order to find a relationship between the relative amount of the elements in a compound and the mass of the very same compound.
In this case, given the mass of each element (chlorine and calcium), one can simply divide it by the sum of the masses of both calcium and chlorine to obtain the following:
[tex]\% Ca=\frac{16.2g}{16.2g+28.8g}*100\%= 36\%\\\\\% Ca=\frac{28.8g}{16.2g+28.8g}*100\%= 64\%\\[/tex]

What will most likely happen when a component is removed from a reaction system at equilibrium?
A. The system will be unaffected by stress.
B. The addition of a catalyst will change the equilibrium.
C. The equilibrium system will shift to remove more of what was removed.
D. The equilibrium system will shift to replace some of what was removed.
When a component is removed from a reaction system at equilibrium, the equilibrium system will shift to replace some of what was removed.
Le Catelier's principleIt states that when a reaction is in equilibrium and one of the factors that affect the rate of reactions is applied, the equilibrium will shift to neutralize the effects of the constraint.
Every equilibrium system obeys Catelier's principle.
Thus, removing one of the components in a reaction that is in equilibrium will make the equilibrium shift to create more of the component being removed.
