Answer:
Banana wafers and chips
Explanation:
Winnowing is the process of separating heavier and lighter components of a mixture by blowing air through the mixture. This implies that the relative weight of the particles in the mixture determines whether they can be separated by winnowing or not.
However, chips are heavier than wafers. wafers refer to a very light snack which is easily blown away by a current of air. Hence banana chips and wafers can be separated using the method of winnowing.
It is Acid Rain since animal activity and plant groth are not types of chemical weathering definetely with frost wedging being physical weathering.
Answer: A=7 for the isotope with 4 neutrons.
Explanation:A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons.
Answer:
d = 1.53 g/mL
Object will sink into water
Explanation:
Given data:
Mass of object = 14.8 g
Initial volume of water = 25.0 mL
Final volume after adding object = 34.7 mL
Density of object = ?
Density of water = 1.00 g/mL
Solution:
Volume of object = Total volume - volume of water
Volume of object = 34.7 mL - 25.0 mL
Volume of object = 9.7 mL
Density of object;
d = mass/volume
d = 14.8 g / 9.7 mL
d = 1.53 g/mL
The density of water is 1.00 g/mL which means object is heavier than water thus object will sink into the water. The object with density less than water are float in it.
