They discovered this since S waves don’t travel through the earth but P waves do. P waves tend to travel faster than S waves in speed, 1&14km/s vs 1&8km/s

How many moles of sulfur are present in 5 moles of h2so4?.
dusya [7]

Answer:

One mole of sulfuric acid consists of one mole of sulphur.

Explanation:

This is because  in the molecule of sulfuric acid there is  only one atom of sulphur that is present. As a result of this since in case of one mole of sulfuric acid there should be only one 1 mole of sulphur.

According to the molar concept one mole of sulphur means 6.023 x10^ 23 atoms of sulphur is present in one complete mole of sulfuric acid. in addition to this the molecule also consists of 2 moles of hydrogen and 4 moles of oxygen in 1 mole of sulfuric acid

to know more about sulfuric acid,

Calculate the density of a material that has a mass of 56.6 g and a volume of 17.2 cm
Cerrena [4.2K]

Answer:

d = 3.29 g/cm³

Explanation:

Given data:

Density of material = ?

Mass of material = 56.6 g

Volume of material = 17.2 cm³

Solution:

Formula;

d = m/v

d = density

m = mass

v = volume

by putting values,

d = 56.6 g/ 17.2 cm³

d = 3.29 g/cm³

Aqueous sulfuric acid will react with solid sodium hydroxide to produce aqueous sodium sulfate and liquid water . Suppose 2.9 g
garri49 [273]

Answer:

1.07 g of water.

Explanation:

A reaction between an acid and a base makes water and a salt as product.

Our reaction is:

H₂SO₄ +  2NaOH  →  Na₂SO₄  +  2H₂O

Reactants are the acid and the base. Which is the limiting?

2.9 g . 1mol /98 g =  0.0296 moles of acid

3.53 g . 1mol / 40 g = 0.088 moles of base

2 moles of base react to 1 mol of acid

0.088 moles may react to (0.088 . 1)/2 = 0.044 moles of acid

And we only have 0.0296, sulfuric acid is the limiting

Ratio is 1:2. 1 mol of acid can produce 2 moles of water.

Our 0.0296 moles may produce (0.0296 . 2) /1 = 0.0592 moles of water.

We convert moles to mass:

0.0592 mol . 18g /mol = 1.07 g
