Answer:

It takes 5.83s to decrease the concentration of the reactant from 0.537M to 0.100M

Explanation:

A zero-order reaction follows the equation:

[A] = [A]₀ - kt

<em>Where [A] is actual reaction of the reactant = 0.100M</em>

<em>[A]₀ the initial concentration = 0.537M</em>

<em>k is rate constant = 0.075Ms⁻¹</em>

<em>And t is time it takes:</em>

<em />

0.100M = 0.537M -0.075Ms⁻¹t

-0.437M = -0.075Ms⁻¹t

5.83s = t

It takes 5.83s to decrease the concentration of the reactant from 0.537M to 0.100M

Which of the following substances heats the fastest?
Aneli [31]

Answer:

Zinc

Explanation:

The specific heat capacity can be described as the amount of heat required to raise the temperature of a substance by one degrees Celsius. It is represented by C or S. The greater the carrying capacity of a substance, the more will be the heat required for that substance.

As we can see in the information given in the question, the specific heat capacity of zinc is the lowest as compared to steel, water and aluminium. Hence, zinc is the correct option.

Standard units of measure for density
Mrrafil [7]

Answer:

g/cm³ for solids,

g/ml for liquids

g/L for gases.

Explanation:

Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids and g/L for gases. Mathematically, density is defined as mass divided by volume:   ρ=m/V
