Answer:
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
Explanation:
The formula for for the heat (q) absorbed by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample. and
ΔT = the change in temperature
1. What you must do
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
2. Sample calculation
For this example, I assume that the specific heat capacity of AlF₃ is 1.16 J·K⁻¹mol⁻¹
.
(a) Calculate ΔT
(b) Calculate m
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:
Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L
Best regards!
Explanation:
37x - 1 + 23x + 1 = 180 ° { being co-interior angles }
60x = 180°
x = 180°/ 60
x = 3 °
Now
< T = 37x - 1° = 37 * 3° - 1 = 110°
Hope it will help :)
Answer:
The answer is “3 moles of molecules”.
Answer:
Detail is given below.
Explanation:
Photosynthesis:
Reactants = Carbon dioxide + water + energy
Products = glucose + oxygen
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
Reactants = Glucose + oxygen
Products = carbon dioxide + water + 38ATP
Chemical equation:
Glucose + oxygen → carbon dioxide + water + 38ATP
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
