There’s no picture? regardless, if there are two numbers of electrons adding up to 8, then they will likely form an ionic bond/compound. if they can form a covalent bond with whatever amount of electrons, ex carbon 4 and 4, then it would b covalent compound

Considering the attached image;

Answer;

- Lithium (Li) and Flourine (F)

Explanation;

-(Li) Lithium and (F) Fluorine would create a binary ionic compound which would be lithium fluoride which would be (LiF). Lithium is an alkali metal in group 1 in the periodic table , while flourine is a halogen in group 7. Lithium reacts by loosing an electron while flourine reacts by gaining one electron. Therefore, they reacts forming LiF which is an ionic compound.

-They would create an ionic compound because lithium is a metal and fluorine is a nonmetal. Metal + Nonmetal = ionic compound.

How many grams of NaOH are needed to make 500 mL of a 2.5 M NaOH solution
Veronika [31]
The number of grams  of NaOH  that are needed to make 500 ml of 2.5 M NaOH solution

calculate the number of moles =molarity x volume/1000

= 2.5 x 500/1000 = 1.25 moles

mass = moles  x molar mass of NaOH

= 1.25 x40= 50 grams of NaOH

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 4 mg. What was t
Degger [83]

Answer : The initial mass of the sample is, 31.9 mg

Explanation :

Half-life = 4 days

First we have to calculate the rate constant, we use the formula :

k=\frac{0.693}{t_{1/2}}

k=\frac{0.693}{4\text{ days}}

k=0.173\text{ days}^{-1}

Now we have to calculate the initial mass of sample.

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  = 0.173\text{ days}^{-1}

t = time passed by the sample  = 12 days

a = initial amount of the reactant  = ?

a - x = amount left after decay process = 4 mg

Now put all the given values in above equation, we get

12=\frac{2.303}{0.173}\log\frac{a}{4}

a=31.9mg

Therefore, the initial mass of the sample is, 31.9 mg
