Answer:
The answer to your question is below
Explanation:
A qualitative property of matter is a property characteristic of a substance like color and flavor.
A quantitative property of matter is a property when we get a number.
A) it's a circular shape is a qualitative property because the shape is a qualitative property and shape is not represented by a number.
B) its mass is 1.5 kg is a quantitative property because we know a number of this mass.
C) it tastes like chocolate is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.
D) it is 30 cm in diameter it is a quantitative property, we know the exact dimension of it.
E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.
Answer:10,900,000,000,000 ozone moles
Explanation:
Answer:
The systematic naming of chemicals is the IUPAC name (International Union of Pure and Applied Chemistry).
Here are the purposes to use it:
1/ It identifies exactly one chemical.
2/ All people over the world can understand it, wherever they are, whoever they are.
It looks like how we recognise the number 1 - 2 - 3: the Americans call them One Two Three, but the Russian call them Odin Dva Tri, etc....

Answer:
0.0102 L or 10.2 mL
Explanation:
From the question given above, the following data were obtained:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole / Volume
With the above formula, we can obtain the volume as follow:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity = mole / Volume
0.250 = 0.00255 / volume
Cross multiply
0.250 × volume = 0.00255
Divide both side by 0.250
Volume = 0.00255 / 0.250
Volume = 0.0102 L
Covert 0.0102 L to mL.
1 L = 1000 mL
Therefore,
0.0102 L = 0.0102 L × 1000 / 1 L
0.0102 L = 10.2 mL
Thus, the volume is 0.0102 L or 10.2 mL
