Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
Answer:
the heat energy is transformed to any kind of energy depending on what it's meant to be transformed to.
remember it cannot be destroyed so it's definitely transformed to some kinda energy
Answer:
4.2 x 10⁴ mL
Explanation:
Data Given:
Density (d) of air = 1.19 x 10⁻³g/mL
Mass of the air (m) = 50 g
Volume of the air (V) = ?
Solution:
Formula will be used
d = m/V
As we have to find volume so rearrange the above equation
V = m/d . . . . . . . . . . . (1)
Put values in above equation 1
V = 50 g / 1.19 x 10⁻³g/mL
V = 4.2 x 10⁴ mL
So,
volume of dry air = 4.2 x 10⁴ mL
