Answer:
C
Explanation:
Answer:
c
Explanation:
Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. Venus is actually only a little bit smaller than our home planet, with a mass about 80% of Earth's.

Which of the following statements are true about energy and bonds?
Check all that apply.
A. The formation of bonds does not absorb or release energy.
B. When bonds are formed, energy is released.
C. Energy is absorbed to break bonds.
D. Breaking bonds does not absorb or release energy.
Answer:
A. Energy is necessary for bond formation.
C. Breaking bonds takes energy.
D. When bonds are formed, energy is released.
Energy is always required for bond formation because when a chemical reaction occurs, either molecular bonds are broken or other bonds are formed to make different molecules. Energy is released during bond formation and is an exothermic process because bond formation represents a stable configuration and the energy lost is released as heat energy that makes it more stable. Breaking bonds takes energy and is an endothermic reaction because energy is absorbed to break bonds.

Which charge does iron (Fe) have in iron sulfate (FeSO4)?
A) -1
B) +2
C) -2
D)+2
The charge on iron (Fe) in iron sulfate (FeSO₄) is equal to +2. Therefore, option (D) is correct.
What are the ionic charges?The ionic charge can be described as the oxidation number of the chemical species. The cation carries a positive ionic charge while Anion carries a negative ionic charge. The number of electrons gained or lost by an atom decides the charge carried by ions.
In the modern periodic table, the elements placed on the left side are electropositive and act as metals because they can donate one or more electrons. The elements placed on the right side are electronegative as they can accept one or more electrons and get a negative charge on their ions.
Considering that the charge on the iron is x, We know that charge on the sulfate ion is -2.
x - 2 = 0
x = +2
Therefore, the charge on iron (Fe) in iron sulfate (FeSO₄) is +2.

2). How are simple carbohydrates, like glucose, used to build starches?
Carbohydrates which include sugars and starches are the primary energy sources produced in plants and used by heterotrophic organisms.
Carbohydrates are composed of a basic chemical formula that typically contains a ratio of one Carbon atom for every two Hydrogen atoms and one Oxygen atom C1H2O1. Basically one carbon atom for every one water molecule Carbon + Water = Carbohydrate.
Monosaccharides or Single Carbon Chain Sugars include Glucose C6H12O6
Disaccharides or Double Carbon Chain Sugars include Sucrose C12H22O11
Combining monosaccharides and disaccharides create Polysaccharides which are complex sugars called starches.

List these distance units in order from smallest to largest: nm,m,km,dm
Answer:
nm, dm, km, m
Explanation:
1 nanometer = 1e-12 (0.000000000001) kilometers
1 decimeter = 1e-4 (0.0001) kilometers
1 kilometer = 1 kilometer
Regardless of whether 'm' stands for mile or meter, it's still larger than all of these being approx. 1.61 and 1e-3 (0.001) kilometers respectively.
in the future, please provide the exact units.

Electrolysis Is One of the Modern Technologies in Architecture’ Prepare an Investigatory Report That Supports the Statement”.
Electrolysis is a technique that separates natural elements. It is commercially used to obtain important materials (e.g., pure metals) for construction.
Electrolysis refers to the use of an electric current to trigger non-spontaneous chemical reactions.
This technology (electrolysis) is commercially important in industry, construction and therefore also in architecture in order to extract metals and minerals from the ground.
Electrolysis uses particular electrolytic cells in order to extract highly pure metals from ores.

9.23 x 10^23 Au atoms= moles Au
Answer:
1.533 moles Au
Explanation:
To find the moles from atoms, you just use Avogadro's number (6.02214076×10^23 mol^-1) and divide by it. Hope this helped!
Answer:
[tex]\boxed {\boxed {\sf 1.53 \ mol \ Au}}[/tex]
Explanation:
We are asked to find how many moles of gold are in 9.23 *10²³ atoms of gold.
Avogadro's Number or 6.022 *10²³ is used to convert atoms to moles. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of gold.
We convert using dimensional analysis. Set up a conversion factor using Avogadro's Number.
[tex]\frac {6.022 \times 10^{23} \ atoms \ Au}{ 1 \ mol \ Au}[/tex]
We are converting 9.23 * 10²³ atoms of gold to moles, so we multiply by this value.
[tex]9.23 \times 10^{23} \ atoms \ Au *\frac {6.022 \times 10^{23} \ atoms \ Au}{ 1 \ mol \ Au}[/tex]
Flip the conversion factor so the units of atoms of gold cancel.
[tex]9.23 \times 10^{23} \ atoms \ Au *\frac { 1 \ mol \ Au}{6.022 \times 10^{23} \ atoms \ Au}[/tex]
[tex]9.23 \times 10^{23} *\frac { 1 \ mol \ Au}{6.022 \times 10^{23}}[/tex]
[tex]\frac {9.23 \times 10^{23} }{6.022 \times 10^{23} } \ mol \ Au[/tex]
[tex]1.53271338426 \ mol \ Au[/tex]
The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 2 in the thousandth place tells us to leave the 3.
[tex]1.53 \ mol \ Au[/tex]
9.23 *10²³ atoms of gold is equal to approximately 1.53 moles of gold.
