Answer:

All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.

Answer:

See explanation

Explanation:

1 ) Al has physical and chemical properties, similar to Boron, because It's also part of group 13, also called the boron group. The elements are characterized by having three valence electrons.

2) Lithium is in group 1. This means it has 1 valence electron.

Nitrogen has 7 electrons. The first shell can only have 2 electrons, so the second and outer shell has 5 electrons. Those 5 electrons are the 5 valence electrons;

Neon is a noble gas, it's in the stable noble gas configuration. This means it has 8 valence electrons.

Oxygen = non-metal because it's a gas

Silicon = metalloid

Helium = non-metal because it's a gas

Arsenic = metalloid

Sodium = it's an (alkali) metal, It is physically silver colored and is a soft metal of low density. Pure sodium is not found naturally on earth because it is a highly reactive metal

Chlorine = non-metal

Tin = Is a soft, ductile and highly crystalline silvery-white metal

Boron = it does conduct electricity. Its chemical properties are mostly, but not entirely, and non-metallic

lead = is a heavy metal that is denser than most common materials

Radon = metalloid

Cesium = It is a soft, silvery-golden alkali metal

Carbon = non metal

Period

⇒ Horizontal from left to right

⇒ same number of atomic orbitals

⇒period = row

Group

⇒ vertical colums

⇒same number of valence electrons

⇒ same physical and chemical properties

Propane reacts with 3.15moles of oxygen how much propane reacts with oxygen

Inessa [10]

27.7g

Explanation:

Given parameters:

Number of moles of oxygen = 3.15moles

Unknown:

Mass of reacting propane = ?

Solution:

Equation of the reaction:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

We work from the known to the unknown parameters.

The known in this expression is the number of moles of oxygen.

In the reaction:

5 moles of oxygen gas reacts with 1 mole of propane

3.15 mole of oxgen gas will react with $\frac{3.15}{5}$ = 0.63moles

Number of moles of reacting propane gas is 0.63moles

To find the mass;

mass = number of moles x molar mass = 0.63 x molar mass

molar mass of propane = (3 x 12) + (8x1) = 44g/mol

mass of propane = 0.63 x 44 = 27.7g

What is the overall charge of the compound frfr

matrenka [14]

Answer:

As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+

Explanation:

The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.

However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a $Fr_2^{2+}$ species which is simply a diatomic ion but not a compound.
