What is the ideal gas constant?
AURORKA [14]

Answer:

Ideal gas constant is a universal constant used for all gases

Explanation:

In Ideal Gases Law, the Ideal gas constant is called R.

It can also be used in Van der Waals equation or, in thermodynamic equations.

R = 0.082 l.atm/mol.K

It is related to the Boltzmann constant, a number that links energy units with temperature units.

Oxygen has an electronegativity of 3.5, and carbon has an electronegativity of 2.5. How is charge distributed on an oxygen atom
Aleksandr [31]

Answer:

The oxygen atom has a slightly negative charge.

Explanation:

3.5 - 2.5 = 1

For ionic bond electronegativity should be more than 1.6.

So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.

The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

Why do roads have speed limits rather than velocity limits
Igoryamba
Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.
