which of the following statements describes how the ionic bond is formed
a.) nonmetals share electrons with other metals.
b.) metals take electrons from nonmetals.
c.) metals allows their electrons to freely move around other metals.
d.) nonmetals take electrons from metals.
Answers
The statement that best describes how the ionic bond is formed is as follows:
Non-metals take electrons from metals.Thus, the correct option for this question is D.
What are Ionic bonds?Ionic bonds may be defined as the type of chemical bond that significantly involves the electrostatic force of attraction between ions of opposite charges, or between two atoms with different electronegativities.
When ionic bonds are formed between atoms or ions, the metal loses electrons and acquires a positive charge over them. They are known as cations. While the non-metals accept those electrons and acquire a negative charge on them. They are known as anions.
Therefore, non-metals taking electrons from metals is one of the statements that best describes the formation of ionic bonds. Thus, the correct option for this question is D.

Answer:
A. The siding on a house buckles on a hot day
Explanation:
The key word in this question is EXPANSION. Without even knowing the siding expands causing it to buckle when it's hot, you can use process of elimination. It can't be answer B because watered down iced tea would most likely be as a result of the ice melting which is the opposite of expanding. It can't be C because air is not solidified and therefore can't expand. Lastly, D cannot be it because ice cream expands when cold, causing it to become hard. If it's not hardening then it's not expanding. This is also the correct answer on a p e.x

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?
- 20 mL
- 259 mL
- 25 mL
- 50 mL
Answers
Answer:
The volume in milliliters is 250mL
Explanation:
The volume of a rectangle is obtained using the equation:
Volume = Length * Width * Height
In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:
Volume = 5cm * 5cm * 10cm
Volume = 250cm³
1mL = 1cm³.
That means the volume in milliliters is 250mL

Balance the following equation:
_ H202 --> _H20+_02
When the equation is balanced, what would be the coefficient in front of H20
Type your answer...
Answers
Given :
A chemical equation :
H₂O₂ → H₂O + O₂
Solution :
We can see that there are 2 oxygen atoms in LHS and 3 on RHS .
So, we can reduce the oxygen atoms to two in THS by just dividing it by 2.
H₂O₂ → H₂O + [tex]\dfrac{1}{2}[/tex]O₂
Now, multiplying both sides by 2, we get :
2H₂O₂ → 2H₂O + O₂
Therefore, the balanced chemical equation is 2H₂O₂ → 2H₂O + O₂ .
