Answer: Option (d) is the correct answer.

Explanation:

Dalton's model of atom states that every matter is made up of atoms and these atoms are indivisible in nature.

On the other hand, Thomson's model of atom states that there are small particles present in an atom that has positive or negative charges.

Thomson's model of atom is also known as plum pudding model where negatively charged particles are represented by plum and positively charged particles are represented by pudding.

Thus, we can conclude that Thomson’s model of the atom include smaller particles that Dalton’s model did not have.

If 250 g of calcium chlorate decomposes into calcium chloride and oxygen, what mass of oxygen would be produced?

sineoko [7]

115.94g of O₂ are produced by 250g of Ca(ClO₃)₂

<u>Explanation:</u>

Ca(ClO₃)₂ -->CaCl₂ + 3O₂

One mole of calcium chlorate give three moles of oxygen.

Molar mass of calcium chlorate is

40+(35.5+16*3)*2 = 207g/mol

Molar mass of Oxygen = 32g

1 mole of calcium chlorate decomposes to form 3 moles of oxygen.

So,

207g of Ca(ClO₃)₂ produces 3 X 32g of O₂

250g of Ca(ClO₃)₂ will produce = $\frac{3 X 32}{207} X 250$

= 115.94g of O₂

Therefore, 115.94g of O₂ are produced by 250g of Ca(ClO₃)₂

Formula one racers speed up much more quickly than normal passenger vehicles, and they also can stop in a much shorter distance.

soldi70 [24.7K]

Answer:

a = -36.8 m/s/s

Explanation:

Initial speed of the car

$v_i = 90 m/s$

finally car will stop after it cover the distance

$d = 110 m$

so we have

$v_f^2 - v_i^2 = 2 a d$

here we have

$0 - 90^2 = 2(a) (110)$

$a = \frac{90^2}{220}$

$a = -36.8 m/s^2$
