The elemental symbol of gold is denoted on the periodic table as being Au.
The answer is b, least to greatest motion.
The higher the temperature a substance is, their particles have more kinetic energy and thus move faster and have a faster motion.
From the pictures, we can see that the state changes from the coldest, ice, to the least cold, water, and to the hottest, steam. Therefore, the hotter the substance it, the water molecules have a greater motion.
So your answer is b.
Answer:
\large \boxed{\text{12.3 mol HCl}}
Explanation:
We need a balanced chemical equation with moles.
2HCl +Ca(OH)₂ ⟶ CaCl₂ + 2H₂O
n/mol: 12.3
The molar ratio is 2 mol H₂O:2 mol HCl.
Answer:
C. physical
Explanation:
A mixture is a physical combination. Mixtures are combinations of compounds and molecules without any chemical reaction taking place.
Mixtures have the following properties:
- They have an indefinite composition i.e they consist of two or more elements and or compounds in any proportion by mass
- Their constituents retains their identities i. e physical property is retained.
- Their constituents reacts differently to changed conditions.
- They are easily separated into constituents by physical methods
