A solid precipitate is formed from the reaction of lead nitrate and sodium chromate. What would be the best method to separate this solid from the solution?

Answers

Answer 1
Answer: The appropriate response is filtration. Filtration is any of different mechanical, physical or organic operations that different solids from liquids by including a medium through which just the liquid can pass. The liquid that goes through is known as the filtrate
Answer 2
Answer: The correct answer would be "filtration". It's a process that has operations that separate solids from fluids. This is done simply by adding a medium through which only the fluid can pass. After the fluid passes through a certain medium it it's called a filtrate.

The chief function of muscles is _____.contraction
absorption
excretion
protection

Answers

Answer:

The correct answer is the first option: contraction.

Explanation:

Hello!

Let's solve this!

Muscles are structures or tissues with a main function that is to contract. This happens so that we can perform each of our movements.

They are divided into smooth muscles and skeletal muscles.

We conclude that the correct answer is the first option: contraction.

Ionization refers to the process ofa. changing from one period to another.
c. turning lithium into fluorine.
b. losing or gaining protons.
d. losing or gaining electrons.

Answers

The ionizationor ionization energy is the process wherein the energy necessary to remove anelectron from the neutral atom. When located in the periodic table, itincreases across the row and decreases going down. The ionization energy isgreatest for the noble gases. For example, the ionization energy for fluorineis 1681.6 kJ/mol.  It means that it takes1681.6 kJ/mol of fluorine to completely remove an electron or ionize it. The answeris d. losing or gaining electrons.
it refers to the process of losing and gaining of electrons

What is an ionic bond?

Answers

In ionic bond there is the formation of ions due to transfer of electrons from one atom to the other. Normally, at this link, there is an element that tends to yield electrons (metal-cation), and one that tends to receive electrons (not metal-anion).
Note: the Ionic bond is the only in the transfer of electrons.
Ionic bonds are when atoms lose or gain electrons so that both elements now have a full outer shell. Ionic bonds form between metals and nonmetals.

the radioisotope radon-222 has a half-life of 3.8 days. How much of a 73.9-gram sample of radon-222 would be left after approximately 23 days?

Answers

There will be 1.11 grams of the sample of radon-222 left. This answer can be obtained using the formula of half life to get the rate constant which will be used in another equation later on.

Half-life (t) = ln2/k = 3.8 days

k = 0.182407/day

Using the general equation of a first order reaction:

Ca/Cao = 1/e^(kt)
Ca/Cao = 0.01506 --> fraction of radon-222 left

This means that 1.51% of the original amount remains, so 1.51% of 73.9 is 1.11 grams.

10.   If a car travels from Town A to Town B on one road at different speeds and stops at red lights, knowing the distance between the towns and the total time of the trip can allow you to calculate     A. instantaneous velocity.B. deceleration.C. average velocity.D. uniform velocity.

Answers

Answer: The correct option is C.

Explanation: Average velocity is defined as the displacement divided by the total time taken by the object.

Mathematically,

\text{Average Velocity}=\frac{Displacement}{\text{Total time}}

We are given, the distance between the two towns and also the total time, so we can easily calculate the average velocity.

Hence. the correct option is C.

Answer : Option C) Average Velocity

Explanation :

As we have the given information about the different speed and the distances between the town and the total trip time, then it will allow anyone to calculate the average velocity of the car.

The average velocity is defined as the displacement divided by the time taken. This will help to determine the average velocity the car was moving with while traveling to various distances.
