Kazeer [188]3 years ago
7 0

Answer:

C.

Explanation:

In terms of bonding, an atom’s chemical behavior is determined mostly by its number of electrons. Atoms will form ionic bonds when their electronegativies are great and are close to filling its outer shell to become stable. The amount of electrons an atom has plays a vital role in ionic bonds as it determines which atom will become a negatively charged ion or positively charged ion. Atoms will from covalent bonds because they are close to each other on the periodic table and share similar properties and therefore will share electrons.

Below is the equation of sucrose and sulfuric acid-producing carbon, water vapor and sulfur dioxide.
Karolina [17]

Answer:

11 is the coefficient for C to balance the equation

Explanation:

C₁₂H₂₂O₁₁(s)  +  H₂SO₄(aq)  +  1/2 O₂(g)   → 11C(s) + CO₂(g) + 12H₂O(g) + SO₂(g)

12 Carbons in left side   →   12 Carbons in right side

12 in sucrose → 11 in solid C + 1 in the CO₂

24 Hydrogens in left side → 24 Hydrogens in right side

22 in sucrose + 2 in sulfuric → 24 in water vapor

1 S in left side → 1 S in right side

1 S in sulfuric → 1 S in sulfur dioxide

16 O in left side → 16 O in right side

11 O in sucrose + 4 in sulfuric + 1 O at ground state → 2 O in carbon dioxide + 12 in water vapor + 2 in sulfur dioxide

oee [108]

Answer:

The density of the liquid is 1.153 grams/ml.

Explanation:

You have to use the fomula of density

density = mass/volume ⇒ density = 376 grams/321 ml ⇒

density = 1.153 grams/ml.

Why do neutral atoms form ions?
Marina86 [1]
Since they can still be unstable...nuetral atoms have the same amount of protons to electrons but to be stable they need to fill up there outer shell by gaining or losing electrons

If 6.49 mol of ethane (C2H6) undergo combustion according to the unbalanced equation
MArishka [77]

Answer:

22.715 moles of oxygen are used

Explanation:

Given data:

Number of moles of ethane = 6.49 mol

Number of moles of O₂ required = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂       →     4CO₂ + 6H₂O

Now we will compare the moles of oxygen with ethane.

                    C₂H₆           :           O₂  

                       2              :             7

                     6.49           :           7/2×6.49 = 22.715 mol

Thus, 22.715 moles of oxygen are used.
