Carlos is making phosphorus trichloride using the equation below.
hjlf

Answer:

C.) 2

Explanation:

Chemical equations, in a way, can be seen as algebraic equations. Cl2 is a molecular structure, so, there are two Cl atoms. 3Cl2 means 3, Cl2 molecules. So, if we think of it as adding up all the atoms, we will get, 2 P atoms and 6 Cl atoms. Now to convert. The Law of the Conservation of Mass basically says you can't add or subtract atoms out of nowhere, so the number of atoms has to stay the same when it's being converted. We need to place a coefficient with PCl3. If we look at PCl3, it shows us that there are three Cl atoms and one P atom. And looking back at how many atoms there were on the left side of the equation, we just need to double the atoms of atoms so it will be equal. So, the answer is C.) 2

Carbon-14 has a half-life of 5,730 years. It is used in "carbon dating" to determine the age of once living organisms. How much
Nookie1986 [14]

Answer:

18 grams

Explanation:

Because 17,190 yrs divided by the amount of years it takes for a half-life to occur is 3. So 3 half life’s happen, so you divide 144/2 once, equaling 72. You divide 72/2 again (another half-life) and you get 36. You then calculate the third half life by dividing 36/2 which equals 18 grams.

Which of the following is not a part of the ideas john dalton proposed in his model
NNADVOKAT [17]

The following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

  • Law of conservation of mass
  • Law of definite proportion
  • Law of multiple proportion

Thus, the following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

To learn more about Dalton atomic theory, refer to the link below:
