Koby decides to change the amount of vinegar. He will keep the amount of baking soda constant at ½ teaspoon. He will run three t

rials with different amounts of vinegar each time.
Trial Baking Soda Vinegar
1 ½ teaspoon ¼ cup (4 tablespoons)
2 ½ teaspoon 2 tablespoons
3 ½ teaspoon 1 tablespoon
Based on what happened in task 1, what do you think will happen with Koby's three trials?

Answer: When baking soda and vinegar are combined, a new substance is produced. The carbon dioxide gas soon foams up in the mixture. Carbon dioxide, water, and sodium acetate are generated when sodium bicarbonate and acetic acid react.As Kobe adds additional baking soda and vinegar, the reaction will also become stronger.

Explanation: <em>well to be completely honest I don't see any answer choices so I'm going to assume that this is a writing question</em>

Calculate the number of moles of sodium oxide that should be produced with 6.50 g of sodium react with oxygen gas
mars1129 [50]
First of all write a balanced equation.
4Na + O2 -> 2Na2O
You are starting with a mass of sodium. You need to use sodium’s molar mass. Take this quantity times mole to mole ratio between sodium and sodium oxide to get moles of sodium oxide produced.

Draw the best lewis structure for bro4- and determine the formal charge on bromine
Svetach [21]

Answer :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The electrons are represented by dot.

The given molecule is, perbromate ion.

Bromine has '7' valence electrons and oxygen has '6' valence electron.

Therefore, the total number of valence electrons in perbromate ion, BrO_4^- = 7 + 4(6) + 1 = 32

According to Lewis-dot structure, there are 14 number of bonding electrons and 18 number of non-bonding electrons.

Formula for formal charge :

\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}

\text{Formal charge on }Br=7-0-\frac{14}{2}=0

The Lewis-dot structure of perbromate ion is shown below.

Ionic bond occurs between two atoms that have different:
Len [333]

Answer:

Ionic bond occurs between two atoms that have different:

a) Electron

Explanation:

according to the definition of ionic bond,

it is the electrostatic force of attraction that holds the two oppositely charged ions together and an ionic bond or electrovalent bond is formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
