Answer:
0.72
Explanation:
if 760=1
550=x
=550÷760= 0.72 in two s.f
Answer:
See explanation.
Explanation:
Hello!
In this case, we can proceed as follows:
1. Here, the undergoing chemical reaction is:
Thus, the moles and mass of water turn out:
2. Here, the undergoing chemical reaction is:
So the required moles of HCl and the yielded of water are:
3. Here, the undergoing chemical reaction is:
Now, we apply each mole ratio obtain:
A.
B.
Best regards!
Answer:
15°
Explanation:
At the lowest temperature the gas will have the lowest rate of diffusion because diffusion deals with the motion of particles.
- Diffusion is the movement of particles from a region of high concentration to that of a lower concentration.
- According to the kinetic molecular theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules.
- The higher the temperature faster the molecules diffuse.
The gas with the lowest temperature will be the slowest to diffuse.
Matter that has a definite volume but no definite shape is a liquid.
