Which of the following was NOT one of the components of Dalton's Atomic Theory? (1 point) All elements are composed of tiny indi

visible particles called atoms. The atoms of any one element are identical to those of any other element. Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction.

Answer: Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction.

Explanation:

Dalton's Atomic Theory was proposed in the 20th century by an English Scientist named John Dalton. His theory is postulated as follows:

1) All elements are composed of tiny indivisible particles called atoms.

2) The atoms of any one element are identical to those of any other element. 3) Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds.

However, the final option is NOT one of Dalton's Theory

air pollution  would cause trees to die and animals to die . It would coaus most harm by killing everything on land and in the sea beacuse the animals that die might wash away in the ocean killing other animals  slowly but surely. and it doesnt help  there is soil erosion sooner rather that later it will turn into nothing.

10.00 mL sample of aqueous HCl requires 31.00 mL of 0.0900 M NaOH to reach the endpoint. What is the molar
AveGali [126]

Answer:

Molar concentration of HCl = 0.279 M

Explanation:

Given data:

Volume of NaOH = 31.00 mL ( 31/1000 = 0.031 L)

Molarity of NaOH = 0.0900 M

Volume of HCl = 10.00 mL (0.01 L)

Molar concentration of HCl = ?

Solution:

Chemical equation:

NaOH + HCl    →   NaCl + H₂O

Number of moles of NaOH:

Number of moles = Molarity × volume in L

Number of moles = 0.0900 mol/L  × 0.031 L

Number of moles = 0.00279 mol

For one mole of HCl one mole of NaOH is required.

Number of moles of HCl = 0.00279 mol

Molar concentration of HCl = 0.00279 mol / 0.01 L

Molar concentration of HCl = 0.279 M
