Answer: All substances are composed of elements.

Explanation: Matter is anything which has mass and occupies space.

The substances can be made up element alone like Helium (He).

They can be made up of molecules of elements also like hydrogen (H_2)

They can also be made up of molecules of compounds like carbon dioxide (CO_2)

They can be made up of mixtures like salt solution in water.

Since all the mixtures, compounds and molecules consists of elements. Therefore, all the substances are composed of elements.

If 3.0 liters of oxygen gas react with excess carbon monoxide at STP, how many liters of carbon dioxide can be produced under th
AlladinOne [14]
At STP, the volume of a gas represents the number of particles.That said, from the chemical reaction one mole of oxygen reacts with two moles of co to produce the product, CO2At STP, 3 moles of Oxygen will produce 6 moles of CO2. Hence It follows that at standard temperature and pressure, 6.0 L of CO2 will be produced. Option D.

Answer:

Covalent bonding

Explanation:

In covalent bonding, the electrons are shared to fill the octet rule (8 electrons in valence shell). CCl4 tends to do covalent bonding because the the 4 valence electrons are Carbon are shared with the Chlorine atoms so that each chlorine atom has a full octet and chlorine shares its electrons to fill the octet of carbon.

Also, since carbon and chlorine are both non-metal, non-metal things exhibit covalent bonding thus this is covalent bonding as well. Ionic boding is for metal and non metal pair where electrons are transferrred, in our case, electrons are shared, they are not transferred.

1826.5g of methanol (CH3OH), molar mass = 32.0 g/mol is added to 735 g of water, what is the molality of the methane 0.0348 m 1.
Snowcat [4.5K]

Answer:

Molality = 1.13 m

Explanation:

Molality is defined as the moles of the solute present in 1 kilogram of the solvent.

Given that:

Mass of CH_3OH = 26.5 g

Molar mass of CH_3OH = 32.04 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{26.5\ g}{32.04\ g/mol}

Moles\ of\ CH_3OH= 0.8271\ moles

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )

So, molality is:

m=\frac {0.8271\ moles}{0.735\ kg}

<u>Molality = 1.13 m</u>

Calculate the molecular mass of carbon monoxide (CO) by adding the atomic mass of carbon (C) and the atomic mass of oxygen (O):
Bond [772]

 The   molecular   mass  of carbon monoxide (CO)  is  28 g/mol


   <u><em>calculation</em></u>

The  molecular  mass  of CO =  atomic mass  of C + atomic  mass  of O

From  periodic table the atomic  mass  of  C = 12 g/mol and for O = 16 g/mol


Therefore the molecular  mass   of Co = 12 g/mol + 16 g/mol = 28 g/mol
