Answer:
Aluminium Chloride and Hyrdron, also known as proton/
Explanation:
Daughter cells are identical after mitosis because they have a copy of the chromosome. Not sure if this helped though
:(
Pure Substance- Element
Explanation:
Pure Substance VS. Mixture:
A pure Substance CANNOT be separated by physical changes, but a Mixture can.
PURE SUBSTANCE: Element VS. Compound:
An Element is one simple atom while a compound is two or more.
Example: Al (Aluminum) is an Element. CaCl (Calcium Chloride) is a compound.
You can split a compound with chemical changes because if you were to take the example, it would be a Calcium atom and a Chlorine atom.
You CANNOT split a single atom (Element) unless you want to make an atomic bomb which takes a lot of energy and you don’t want to destroy the whole world.
MIXTURE: Homogeneous VS. Heterogeneous:
Homo- mixed; cannot differentiate pieces
Hetero- can differentiate pieces
EX: homo- ketchup (can you see the difference in the vinegar and tomato paste? No)
Hetero- chicken noodle soup (there’s broth, chicken, peas, carrots, and other things)
Answer:
Q = 1.44×10⁴ J
Explanation:
Given data:
Mass of water = 62.5 g
Initial temperature = 25.5°C
Final temperature = 80.7°C
Specific heat capacity of water = 4.184 J/g.K
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 80.7°C - 25.5°C
ΔT = 55.2 °C
Q = 62.5 g × 4.184 J/g.°C × 55.2 °C
Q = 14434.8 J
Q = 1.44×10⁴ J
I just know the ph is between 7 and 8
