Answer:
218.02 mL
Explanation:
Data Given:
weight of the empty beaker = 49.03 g
weight of water and beaker = 267.05 g
density of water = 1 g/mL
Solution:
As we know that the volume that beaker hold is the volume of water that occupied by it.
For this first we have to find mass of the water in the beaker
This can be calculated by the subtraction of beaker's weight from the weight of beaker and water.
weight of water (m) = total weight - weight of beaker
put values in the above formula
weight of water (m) = 267.05 g - 49.03 g
weight of water (m) = 218.02 g
To find volume we will use density formula
d = m/v
rearrange the above equation to calculate volume
v = m/d . . . . . . . (1)
put values in equation 1
v = 218.02 g / 1 (g/mL)
v = 218.02 mL
The volume that beaker hold = 218.02 mL
Answer 1 and 2 are true for alkaline solutions.
Acids have a pH below 7. (this is the answer)
Both acids and bases are electrolytes as they have free moving ions.

Answer:
The sand bath spreads the heat out so that the flask is heated evenly. This reduces the chance of the flask breaking and ensures that there are no hot spots in the reaction mixture which could lead to excessive charring,
Explanation:
Shallow ones are seismic waves from deep quakes that have to travel farther to the surface, losing energy along the way. shaking is more intense from quakes that hit close to the surface.
