Answer:

2.67761514 moles

Explanation:

0.075kg equates to 75g.

This means that the car emits 75g of CO per km.

dividing 75g by the molar mass of CO (28.01g/mol) we get 2.67761514 moles

The correct matches are as follows:

1. Big Bang theory: Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.

2. Steady state theory: Theory about the origin of the universe that suggest that the universe has and will continue to be at a steady continuous state.

3. Oscillatory universe theory: Theory about the origin of the universe that suggests the universe is a never ending cycle of expansion and contraction.

4. Nebular theory: Theory about the origin of the solar system that suggest our sun and planet formed from a cloud of dust and gas.

5. Inflation theory: Theory that upholds the big bang theory but suggest there was an extremely rapid expansion or inflation milliseconds after the big bang.

6. Condensation theory: Theory about the origin of the solar system that agree with the nebular theory but stresses the importance of interstellar dust in planet formation.

What is the difference between electron dot structure and lewis structures
ivanzaharov [21]

Answer:

I hope this helps

Explanation:

Lewis symbols, which are also known as Lewis dot diagrams or electron dot diagrams, are diagrams that represent the valence electrons of an atom. Lewis structures, also known as Lewis dot structures or electron dot structures, are diagrams that represent the valence electrons of atoms within a molecule.

When a metal is burned in a closed container, the mass of the container and its contents do not change.a. observation. b. law. c
Annette [7]

Answer: Option (b) is the correct answer.

Explanation:

According to the law of conservation of mass, mass of a substance can neither be created nor it can be destroyed but it can simply be transformed from one form to another.

Therefore, when a metal is burned in a closed container, the mass of the container and its contents do not change because they follows law of conservation of mass.

Thus, we can conclude that when a metal is burned in a closed container, the mass of the container and its contents do not change then it is a law.

Given that the concentration of myosin is 25pmol·L−1 and Rmax(Vmax)=208pmol·L−1·s−1 , determine the turnover number of the enzym
DedPeter [7]

Answer:

8.32 s⁻¹

Explanation:

Given that:

The concentration of myosin = 25 pmol/L

R_max = 208 pmol/L/s

The objective is to determine the  turnover number of the enzyme molecule myosin, which has a single active site.

In a single active site of enzyme is known to be a region where there is binding of between substrate molecules, thereafter undergoing chemical reaction.

The turnover number of the enzyme is said to be the number of these substrate molecule which binds together are being converted into products.

The turnover number of the enzyme molecule of myosin can be calculated by the expression: \dfrac{R_{max}}{concentration}

⇒ \dfrac{208 pmol/L/s}{25 pmol/L}

= 8.32 s⁻¹
