37.8 grams of CS2 equals to 37.8/76=0.5 mole. So the products have 0.5 mole CO2 which is 11.2 liters at STP. So according to the gas law, the volume at given condition is 12.4 liters. So the answer should be 12.2 liters.
Answer:
Soil is heterogeneous mixture of sand particles of different sizes, shape and of different compositions.
Explanation:
Homogeneous mixtures are defined as the mixtures in which components are evenly spread throughout the solution. The size and shape of the particles are similar in these mixtures.
For example : alloys, salt solution.
Heterogeneous mixtures are defined as the mixtures in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures.
For example : sand in a water, soil etc.
Brass is an alloy homogeneous mixture of metals.
Air is a homogeneous mixture of gases.
Coffee with sugar stirred in is also homogeneous mixture.
Soil is a heterogeneous mixture of sand particles of different sizes, shape and of different compositions.
Assuming the complete question is;
Consider the balanced equation below;
4NH3 + 3O2 = 2N2 +6H2O
What is the mole ratio of NH3 to N2;
From the balanced equation; the mole ratio of NH3 to N2 is 4:2.
The mole ratio is the ratio of moles of one substance to the number of moles of another substance in a balanced equation. In the above equation; 4 moles of ammonia requires 3 moles of oxygen to produce two moles of nitrogen and six moles of water.
Answer:
A neutral atom of Cobalt (Co) has an atomic number of 27 and an atomic mass of 59. Therefore, Co has 27 electrons, 27 protons and 32 neutrons.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
The atomic number Co is 27 it means it has 27 protons and 27 electrons.
The mass number is sum of protons and neutrons, thus number of neutrons are
59 - 27 = 32 neutrons
