Answer:

ionic bonds and convalent bond

Explanation:

by taking the electrons it means convalent bond

but if you're borrowing the electrons it mean ionic bond

Answer: one way is that the atom will share an electron. Sorry i only know 1 way

Explanation: for example, if Cl with 7 electrons wants to bond with Ar, that has a conplete set of 8 electrons, then Ar will share its electron to fill in the space of the missing electron in Cl.

*JUST AN EXAMPLE. IM NOT SAYING CL AND AR DO FORM A BOND.

Which is true about the pH values of a 1.0 M solution of HCl (a strong acid) and a 1.0 M solution of HC2H3O2 (a weak acid)?
Neko [114]

Answer:

C. pH values are different because the HC_2H_3O_2 solution partially ionizes and the HCl solution ionizes 100 percent.

Explanation:

Strong acids are the acids which completely ionizes in the solution while weak acids are the acids which ionizes partially in the solution. They exists in equilibrium in the solution with their respective ions.

Thus, strong acids furnish greater concentration of protons as compared to weak acid when same concentration of both types are taken.

<u>Also, pH is the negative of the logarithm  of the hydrogen ions. Thus, hydrogen ion concentration for both acids are different and thus pH will be different.</u>

8. What is the % weight of Nickel in Nickel Sulfamate (Ni(SO3NH2)2) ?​
uranmaximum [27]

Answer:

% weight of nickle = 24 %

Explanation:

molar mass of Nickel Sulfamate (Ni(SO₃NH₂)₂) = 250.87 g/mol

Solution

1st we write down the molar mass of Ni

molar mass of Ni = 59 g/mol

now we write down the number of moles of Ni in (Ni(SO₃NH₂)₂)

number of moles of Ni = 1 mol

Now we calculate the mass of nickle present in (Ni(SO₃NH₂)₂)

<em>         mass = moles × molar mass</em>

mass = 1 mol × 59 g/mol

mass = 59 g

now we calculate the % weight of nickle in (Ni(SO₃NH₂)₂)

<em>       % weight = (weight of element ÷ total weight) × 100</em>

% weight of nickle = (59 ÷ 250.87) × 100

% weight of nickle = 0.24 × 100

% weight of nickle = 24 %
