Explanation:

34.2g of C12H22O11 is dissolved in 180g of H20.

Molar mass of sucrose = 342g/mol

Moles of sucrose = 342 / 34.2 = 10 mol.

Molar mass of water = 18g/mol

Moles of water = 180 / 18 = 10 mol.

For hydrogen atoms, there are 22 * 10 in sucrose and 2 * 10 in water, which gives a total of 240.

For oxygen atoms, there are 11 * 10 in sucrose and 1 * 10 in water, which gives a total of 120.

3. What is the greatest amount of H2O that can be made with 3.8 moles of H and 5 moles of
Pachacha [2.7K]

Answer:  Hello!

first i believe we need a balanced equation to start...

i got 2H2 + 1O2 = 2H2O

This tells us that we need 2 moles of H2 for every 1 mole of O2 Since we only have 1 mole of H2 compared to the 5 moles of O2 hydrogen is the limiting reagent. For illustration, divide the balanced equation by 2 in order to get 1 mole of H2 If we start with 1.0 moles of H2 we'll produce 1.0 mole of H2O

Your welcome <3

What does a mole of iron weigh
r-ruslan [8.4K]

As the atomic mass of iron is 55.847u

We say that it is the mass of one mole of iron.

By formula it can be find by

No.of mole=mass in g/molar mass

Mass in gram = no.of mole x molar mass

No.of mole =1

Molar mass = 55.847g

Mass in gram = 1x55.847

= 55.847g of Fe

What is the potential energy of a car with a mass of 1200kg at the top of a 42m high hill?
GalinKa [24]

Answer:

P.E = 493920 j

Explanation:

Given data:

Mass = 1200 kg

height = 42 m

Potential energy = ?

Solution:

Formula:

<em>P.E = mgh</em>

Now we will put the values in formula.

g = 9.8 m/s²

P.E = 1200 Kg × 9.8 m/s²× 42 m

P.E = 493920 Kg.m²/s²

Kg.m²/s² = j

P.E = 493920 j

the element cesium forms a with the charge fill in the blank 2 . the symbol for this ion is , and the name is fill in the blank
yulyashka [42]

The element cesium forms a  positive ion with the charge +1 . The symbol for this ion is Ce⁺, and the name is cesium ion. The number of electrons in this ion is 54.

<h3>What group does the element cesium belong to in the periodic table?</h3>

Cesium belong to the Group 1A of the periodic table.

Group 1A elements are known as alkali metals.

The alkali metals react with water to form alkalis. They form ions with a positive charge of +1 by the loss of an electron.

In conclusion, cesium is an alkali metals it belongs to group 1A of the periodic table. It forms a positive ion with a charge of +1 by the loss of an electron.
