How many total atoms of oxygen are present in the molecules represented here?

Answers

Answer:

The answer is 36 atoms

Explanation: I took the test and i got 100%

There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

We have the expression "6 C₆H₁₂O₆", which represents 6 molecules of C₆H₁₂O₆.

The subscripts are the atomicities of the element, that is, the number of atoms of each element in 1 molecule.

There are 6 atoms of oxygen per molecule of C₆H₁₂O₆. Considering that there are 6 molecules, the total number of atoms of oxygen are:

[tex]6 Molecules \times \frac{6\ O\ atoms}{1Molecule} = 36\ O\ atoms[/tex]

The density of a liquid is 6.0g/cm3 , when it fills a container of volume 300cubic centimeters . What is the mass of the liquid in the container?

Answers

Answer:

1800g

Explanation:

b/c d=m/v

m=dv

m=300×6=1800g

The mass of the liquid in the container is equal to 1800 g.

What is the density?

The density of an object can be described as the mass per unit volume of the object. The average density of any substance equals the total mass of the substance divided by its total volume.

The mathematical formula of the density can be expressed as follows:

The density of material = Mass/Volume

Mass = density × Volume

The S.I. unit of the density of any substance is Kg/m³ and it is an intrinsic property. If the size of the substance increases, the mass increases as well but the density of the substance will stay constant.

Give, the density of the liquid, d = 6.0 g/cm³

The volume of the container, V = 300 cm³

The mass of the liquid = 6 ×300 = 1800 g

Therefore, the mass of the liquid is equal to 1800 g.

How many moles of HCl will be produced when 34.56 g of AIC3 are reacted according to this chemical equation​

Answers

Answer:The answer to your question is It will be formed 0.39 moles of H₂

Data

moles of H₂ = ?

moles of HCl = 0.78

moles of Zinc = excess

Balanced chemical reaction

             2 HCl  +  Zn  ⇒  1 H₂  +  ZnCl₂

Process

Explanation:

1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.

              2 moles of HCl ---------------------- 1 mol of H₂

              0.78 moles of HCl -----------------  x

              x = (0.78 x 1) / 2

- Simplification

             x = 0.78 / 2

- Result

             x = 0.39 moles of H₂

Which element in Fe(NO3) is a metal?
O
N
Fe

Answers

Answer:

Explanation:

Most periodic tables have a staircase thick line on their right side. This line separates the metals from the non metals.

O (oxygen) and N (nitrogen) are on the right side of the staircase.

Fe is on the left.

Those elements on the right side of the staircase are non metals.

Those elements on the left of the staircase are metals, so Fe is a metal.

the mass number for an atom is numerically equal to which quantity

Answers

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

Explanation:

protons

The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

3.7x10^45 molecules of hydrogen gas = how many grams of hydrogen gas

Answers

Answer:  6.19 × 10²¹ g

Explanation:

Since we weren't given the moles of hydrogen, we have to find it. However, we can do it all in one step if we set up the equation correctly.

Since   Mass = moles × molar mass

&         Moles = #molecules ÷ Avogadro's Number

∴ mass = (#molecules ÷ Avogadro's Number) × molar mass

            =  (3.7 × 10⁴⁵ mcules ÷ (6.022 × 10²³ mcules/mole)) × 1.008 g/mol)

            = 6.19 × 10²¹ g

a motorcycle travels 95.0 km/hr. how many seconds will it take the motorcycle to cover 2.70*10^3 m?

Answers

Answer:
102.35s

Explanation:
Do we currently have km/hr, yet the question is asking for m/s
To convert, we just multiply (95km/1hr) by (1000m/1km) and (1hr/3600s)
This effectively converts km/hr to m/s
This will give us 26.38m/s
Then we must divide (2.7*10^3m) by 26.38m/s
This cancels out the meters and leaves us with seconds:
2700/26.38 = 102.35 seconds
