Which pair of elements forms the most ionic bond? Refer to the periodic table.
A) K and CI
B) Be and CI
C) Li and CI
D) O and CI
Answers
Answer:
KCl
Explanation:
Look at the electronegativity differences between the pairs of elements:
KCl: 3.16 - 0.82 = 2.34
BeCl: 3.16 - 1.57 = 1.59
LiCl: 3.16 - 0.98 = 2.18
ClO: 3.44 - 3.16 = 0.28
KCl has the highest electronegativity difference; thus it is the most ionic bond of the 4.

What is chemical reacts?A chemical reaction is a procedure that causes one group of chemical components to change chemically into another. According to Wikipedia, a chemical reaction is a process in which one or more compounds, known as reactants, change into one or more other substances, known as products. Chemical elements or chemical compounds make up substances.When two or more molecules combine to create a new product, the process is known as a chemical reaction (s). Products, as opposed to reactants, are the compounds that result from an interaction between two other substancesChemical reactions are the process by which an existing chemical substance is changed into a different chemical substance by forming and breaking bonds between various atoms.To learn more about chemical reacts refer to:

If 3.3167 moles of Al are produced, how many moles of
AlCl3 were reacted?
I
Answers
Answer:
3.3167 moles Of AlCl3
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
3Ca + 2AlCl3 —> 3CaCl2 + 2Al
From the balanced equation above,
2 moles of AlCl3 reacted to produce 2 moles of Al.
Finally, we shall obtained the number of moles of AlCl3 that reacted to produce 3.3167 moles of Al as follow:
From the balanced equation above,
2 moles of AlCl3 reacted to produce 2 moles of Al.
Therefore, 3.3167 moles Of AlCl3 will also react to produce 3.3167 moles of Al.
Thus, 3.3167 moles Of AlCl3 is needed for the reaction.

What do insects use to get oxygen? A. lungs B. spiracles C. gills D. stomata
Answers
Answer:
B spiracles
Explanation:
These are the tubes connected to the openings in their sides
Insects use tiny openings in their body wall called spiracles to get oxygen. They are also called tracheal tubes. Hence, option B is correct.
What is insect spiracles ?An insect's inside functions almost like a sponge. Because a sponge has tiny holes that allow water to enter, it becomes moist. Spiracles are similar to this. They allowed oxygen to enter the bug's body. They then release carbon dioxide.
Insects can open and close their spiracles . This is accomplished through certain muscles . To drive oxygen through their bodies, insects can also contract their muscles. The oxygen inside them is spread out by doing this.
Stomata is the reparatory organ in plants and gills are the organ in aquatic livings for respiration. In mammals lungs are the respiratory organ. Therefore, option B is correct.

Option A. Add one green candy
Explanation:
From the question given above, the following data were obtained:
Red color => Proton
Green => Neutron
Blue => Electron
Isotopy is a phenomenon where by two or more elements have the same atomic number by different mass number due to the difference in the neutron number. The atoms involved are called isotopes.
From the above definition, isotope exist when the neutron number of the atoms are different with each having same atomic number (i.e proton number).
Thus, considering the question and the options given above, the only way to make a different isotope of oxygen is to add a green candy (i.e neutron).

Answer:
If you count the number of protons this atom has it adds up to 3, which, therefore comfirms that this molecule is Li. The number of protons is specific to the atom. The question states that this element has a mass number of 7, this is because the mass number is the sum of both protons and electrons.

How many joules of energy are made by the loss of 100kg of mass using the formula E=mc2? please help!!!
Answers
Answer:
E = 3 × 10¹⁰ J
Explanation:
Mass, m = 100 kg
We need to find energy made by the loss of 100 kg of mass. The formula between the mass and energy is given by :
E = mc²
Where c is speed of light
Putting all the values, we get :
E = 100 kg × (3×10⁸ m/s)²
= 3 × 10¹⁰ J
So, the required energy is 3 × 10¹⁰ J.
