The combustion of 14 grams of co, according to the reaction co(g) + ½o2(g) → co2(g) + 67.6 kcal, gives off how much heat?

The amount of heat released by the combustion of 14 g of CO is 33.8 kCal

Explanation:

To calculate the number of moles, we use the equation:

Given mass of CO = 14 g

Molar mass of CO = 28 g/mol

Putting values in above equation, we get:

The chemical reaction for the combustion of CO follows the equation:

By Stoichiometry of the reaction:

If 1 mole of CO produces 67.6 kCal of heat

Then, 0.5 moles of CO will produce = of heat.

Hence, the amount of heat released by the combustion of 14 g of CO is 33.8 kCal

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
