What volume of O2 would be required to react with 4.6 grams of Na

Answers

Answer 1

Volume of O₂ = 1.12 L

Further explanation

The reaction equation is the chemical formula of reagents and product substances  

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products  

Reaction

4Na+O₂ ⇒ 2Na₂O

Ar Na = 23 g/mol

mol Na :

[tex]\tt mol=\dfrac{4.6}{23}=0.2[/tex]

mol O₂ :

[tex]\tt \dfrac{1}{4}\times 0.2=0.05[/tex]

Assume at STP (0 C, 1 atm), 22.4 L for 1 mol , then volume of O₂ :

[tex]\tt 0.05\times 22.4=1.12~L[/tex]

A cart has a mass of 35kg and a speed of 1.2m/s. What is its kinetic energy

Answers

Answer:

The answer is 25.2 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question we have

[tex]KE = \frac{1}{2} \times 35 \times {1.2}^{2} \\ = 17.5 \times 1.44 [/tex]

We have the final answer as

25.2 J

Hope this helps you

Answer:

25.2 J

Explanation:

Using the kinetic energy formula:

KE = [tex]\frac{1}{2}[/tex]m v²

Plug in the given values:

KE = [tex]\frac{1}{2}[/tex] (35 kg) · (1.2 m/s)²

KE = [tex]\frac{1}{2}[/tex] (35) · 1.44

KE = 17.5 · 1.44

KE = 25.2 J

There is a kinetic energy of 25.2 Joules.

does anyone have any information about "trititanium pentoxide" or "titanium oxide"? ​

Answers

Answer:

Commonly available heat-storage materials cannot usually store the energy for a prolonged period. If a solid material could conserve the accumulated thermal energy, then its heat-storage application potential is considerably widened. Here we report a phase transition material that can conserve the latent heat energy in a wide temperature range, T<530 K and release the heat energy on the application of pressure. This material is stripe-type lambda-trititanium pentoxide, λ-Ti3O5, which exhibits a solid–solid phase transition to beta-trititanium pentoxide, β-Ti3O5. The pressure for conversion is extremely small, only 600 bar (60 MPa) at ambient temperature, and the accumulated heat energy is surprisingly large (230 kJ L−1). Conversely, the pressure-produced beta-trititanium pentoxide transforms to lambda-trititanium pentoxide by heat, light or electric current. That is, the present system exhibits pressure-and-heat, pressure-and-light and pressure-and-current reversible phase transitions. The material may be useful for heat storage, as well as in sensor and switching memory device applications.

Ribosomes are cell structures that make

Answers

Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains.

Ribosomes are cell structures that make protein. They are the primary site of the synthesis of protein. They are made up of protein and RNA.

What are ribosomes?

Ribosomes are cell organelles scattered in the cytoplasm of the cell. They are tiny and round vesicles. They are present in both prokaryotic and eukaryotic cells. Furthermore, they are present freely in the cytoplasm. Ribosomes are also present near the endoplasmic reticulum.

Ribosomes are made up of RNA and protein, and they synthesize the protein in the cell. Ribosomes read the mRNA and by these codes of mRNA, it constitutes amino acids, that grow into a long chain of the protein.

Thus, ribosomes are the parts of cells that produce protein. They serve as the central location for protein production. They are composed of RNA and protein.

How will oxygen appear in the final chemical equation?
O O2(g) as a product
O O2(g) as a reactant
O O(g) as a product
O 20(g) as a reactant

Answers

O₂(g) as a reactant

Further explanation

In chemical reactions, there is a reaction between reagents and products

Reaction:

aA + bB ⇒ cC

Substances A and B are called a reactants

Substance C is called a product

In the above reaction:

Reactants: C, O₂ and CO Products: CO and CO₂

CO functions as a product in the first reaction and functions as a reactant in the second reaction  

In the final chemical equation :

CO(g)+30₂(g) → CO₂(g)

O₂ is on the left so it is called the reactant

Answer: B. O₂(g) as a reactant

Why are electron filling orders not the same between the first and the last two elements of group 6B?​

Answers

Answer:

This primarily has to do with the balance of energy between the orbitals. The aufbau principle states that the order of energy regarding electrons in the orbitals from lowest to highest is so the electron in the atom will minimalize it's energy. Periods on the periodic table are based on the energy level while the groups have the same amount of valence electrons. The outer orbitals are refered to as shells. The elements are particularly arranged depending on their atomic and molecular orbitals. Valence electrons most determine the chemical properties of an element. The atomic number is based on the number of protons.
