Answer:
I think it's b if not then sorry
The number of moles of
form from 5.0 moles
is 5 moles.
<h3>What is a limiting reactant?</h3>
Limiting reactants are those reactants that are completely used up in a chemical reaction.
4.0 mol
will be completely used since the combining ratio is 1 : 1 : 1.
->
From the chemical equation above, 5.0 moles
will yield 5 moles of
.

Answer: False
Explanation: Electrolyte are good conductors of electricity because they contain ions which are able to move about
Answer:
Explanation:
Q = Ce . m .ΔT
Q : calor
Ce : calor especifico
m: masa
ΔT : variación de temperatura
capacidad térmica : 0,550 cal / °C
lectura :
por 1 °C se tiene 0,550 cal
por lo tanto tenemos datos de la temperatura y del calor
pero no olvidar las unidades en el sistema internacional :
Ce : J / kg . K
J: joules
kg: kilogramo
K: kelvin
pasar de gramos a kilogramos
pasar de calorías a joules
pasar de grado celsius a kelvin
1000g equivale a 1kg
15g equivale a 0,015 kg
K= °C + 273 ⇒ formula para pasar de grado celsius a kelvin
K= 1 + 273
K= 274
1 caloría equivale a 4,184 joules
0,550 caloría equivale a 2,3012 joules
ahora como todos los datos ya están en el S.I remplazamos en la formula
Q = Ce . m .ΔT
2,3012 = Ce . 0,015.274
Ce=0,5599 J / kg. K
Answer:
1.62 × 10⁴ cal
Explanation:
Step 1: Given and required data
- Mass of water (m): 30.0 g
- Latent heat of vaporization of water (ΔH°vap): 540 cal/g
Step 2: Calculate the heat change (Q) for vaporization of 30.0g of water at 100 °C
The vaporization is a phase change in which water passes from the liquid state to the gaseous state. We can calculate the heat required using the following expression.
Q = ΔH°vap × m
Q = 540 cal/g × 30.0 g
Q = 1.62 × 10⁴ cal
