Naya [18.7K]4 years ago
4 0

Answer:

The answer is

<h2>126.58 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

<h3>volume =  \frac{mass}{density}</h3>

From the question

mass of alcohol = 100 g

density = 0.79 g/mL

The volume is

volume =  \frac{100}{0.79}  \\  = 126.58227848...

We have the final answer as

<h3>126.58 mL</h3>

Hope this helps you

How many grarns would 3 moles of carbon dioxide (CO2) weigh? (round to the
BigorU [14]

Mass of CO₂ = 132 g

<h3>Further explanation   </h3>

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

mole also can be formulated :

\tt n=\dfrac{mass}{MW}

moles of CO₂ = 3

mass of CO₂(MW=44.01 g/mol) :

\tt mass=mol\times MW\\\\mass=3\times 44.01\\\\mass=132.03~g\approx 132~g

Change the following word equation into balanced formula equation
Natali [406]

Answer:

Fe + CuO ----> FeO+ Cu

Explanation:

A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.

Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.

The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.

marishachu [46]
Because if they are submerged in the solvent, they would dissolve! This would prevent them from seperating and not allow you to actually record anything
