Answer:
2J/g°C
Explanation:
Q = 5000J
Initial temperature (T1) = 20°C
Final temperature (T2) = 70°C
Specific heat capacity (c) = ?
Heat energy (Q) = mc∇T
Q = mc∇T
Q = mc(T2 - T1)
5000 = 50 × c × (70 - 20)
5000 = 50c × 50
5000 = 2500c
c = 5000 / 2500
c = 2J/g°C
The specific heat capacity of the substance is 2J/g°C
Answer:
<h3>The answer is 123.72 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 157 mL
density = 0.788 g/mL
We have
mass = 0.788 × 157 = 123.716
We have the final answer as
<h3>123.72 g</h3>
Hope this helps you
Steroids are like hormones that
greatly influences bodily activities mostly in growth and function. These
functions may modify, change and control one’s body organs or system that’ll
