The reaction of sulfuric acid (H2SO4) with potassium hydroxide (KOH) is described by the equation below. Suppose 0.05 L of KOH w
strojnjashka [21]

From the chemical equation given:

H2SO4+2KOH--->K2SO4+2H2O

the two reactants, H2SO4 and KOH, are in 1:2 stoichiometric ratio.

No. of moles of KOH = 2* no. of moles of H2SO4

=2*0.1*0.033

The concentration of KOH = no. of moles / volume

=2*0.1*0.033/0.05

=0.132M

Vlad [161]

The question is incomplete, the complete question is:

Which statements are consistent with Dalton's atomic theory as it was originally stated? Why?

a. Sulfur and oxygen atoms have the same mass.

b. All cobalt atoms are identical.

c. Potassium and chlorine atoms combine in a 1:1 ratio to form potassium chloride.

d. Lead atoms can be converted into gold.

<u>Answer: </u>The correct options are b) and c).

<u>Explanation:</u>

Some of the postulates of Dalton's atomic theory are:

  • All matter is made of very tiny particles called atoms that participate in chemical reactions
  • Atoms are indivisible particles that cannot be created or destroyed in a chemical reaction
  • Atoms of a given element are identical in mass and chemical properties
  • Atoms of different elements have different masses and chemical properties.
  • Atoms combine in the ratio of small whole numbers to form compounds.
  • The relative number and kinds of atoms are constant in a given compound.

For the given options:

<u>For a:</u>

The statement is inconsistent with the theory as no two elements can have the same mass. Only atoms of the same element can have the same mass.

  • <u>For b:</u>

This is consistent with the theory as atoms of the same element are identical.

  • <u>For c: </u>

This is consistent with the theory as atoms combine in a simple whole number ratio.

  • <u>For d:</u>

The statement is inconsistent with the theory as atoms of one element cannot be changed to atoms of other element.

Hence, the correct options are b) and c).

1. Calculate the momentum of a 1,500 kg car traveling at 6 m/s.
ziro4ka [17]

Answer:

1.9000kgm/s

2.258,000kgm/s

Explanation:

1.Momentum is given as the product of mass by velocity of an object.

Momentum,p=mv

m=1,500kh, v=6m/s

p=1500*6\\p=9000kgm/s

2.Momentum,p=mv

m=7800kg, v=30m/s

p_1=7800*30\\p_1=234,000kgm/s\\

new mass=7800+800=8600

As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

p_2=8600*30\\p_2=258,000kgm/s
