For the following hypothetical reaction: 3A + 5B —> 3C. How many moles of C can you produce with 2 moles of A and excess B?

kompoz [17]

Answer:

2 mol

Explanation:

3A + 5B ⟶ 3C

n/mol: 2

The molar ratio is 3 mol C:3 mol A

$\text{Moles of C} = \text{2 mol A} \times \dfrac{\text{3 mol C}}{\text{3 mol A}} = \textbf{2 mol C}$

a metal weighing 50.0g absorbs 20.0j of heat when its temperature increases by 150.0°c . what is the specific heat of the metal

nadezda [96]

Answer:

2.677 J/g°C

Explanation:

Quantity of heat required to raise the temperature of the metal,

Q = mc∆T

where m is the mass of the metal, c is the metal's specific heat capacity, and ∆T is the change in temperature that accompanies the heat transfer process

20.0J = 50.0g × c × 150°C

c = 20.0J/(50.0g × 150°C)

c = 2.677 J/g°C
