standard units of measure for density
Answer:
g/cm³ for solids,
g/ml for liquids
g/L for gases.
Explanation:
Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids and g/L for gases. Mathematically, density is defined as mass divided by volume: ρ=m/V
What is the mass number of beryllium
Answer:
9.012182 u
Explanation:
- 1. Justin usually blows his nose using Kleenex tissues. His snot keeps leaking through the tissue. He decided he is going to create an experiment to find out if there is something better. What is his dependent variable? - A. Justin - B. Amount of snot the tissue can hold - C. Amount of tissue - D. Type of tissue
Answer:
B. Amount of snot the tissue can hold
Explanation:
In this specific scenario, the dependent variable would be the amount of snot the tissue can hold. That is because this is what Justin is trying to measure, which is also dependent on the type of tissue which would be the independent variable in this scenario. The different types of tissues can absorb different amounts of snot and this is what Justin ultimately wants to determine.
The density of plutonium is 19.84 g/cm². What is its mass if the container has
volume of 250 cm?
Answer:
the answer is 7.936X 10⁻⁷kg.... the unit for volume must be cm³
Explanation:
we know,
ρ =m/v
given,
ρ =19.84/1000X(100)²= 1.984X10⁻⁶kg/m²
V (volume of the container means the volume of the element)=2.5 m³
NOW putting in the equation
1.984X10⁻⁶/2.5=m
or, m=7.936X 10⁻⁷kg(ANS)

Which event always involves a chemical change A boiling B melting C conducting D burning
Answer:
burning
Explanation:
When a chemical change occurs, the matter is transformed into a new substance. When a substance is burned, it will change into something new. Thus, you know that burning is a chemical change. All the other options are physical properties. The substances may change state, but they will not change identities.

which of the following substances does not conduct electricity
a)brass b)copper c)carbone(graphite) d)carbon(diamond)
Answer:
diamonds
Explanation:
Diamond does not conduct electricity.
• A form of carbon in which each of the atom of carbon is joined to four other atoms of carbon, giving rise to a giant covalent composition is a diamond.
• Due to this, diamond is very robust and exhibits high melting point. Thus, is used to cut tools.
• Diamond does not conduct electricity, due to the absence of delocalized electrons in the structure.
Thus, diamond does not conduct electricity. Option d is correct.

Which property refers to how a mineral reflects light?
Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.
Answer:
It is definitly Luster
Explanation:
How shiny something is or how its acts in the sun

Answer:
Explanation:
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid

what are 5 physical changes in matter
Answer:
cutting, bending, dissolving, freezing, and boiling
Explanation:
A physical change is a change in one or more physical properties of matter without any change in chemical properties. In other words, matter doesn't change into a different substance in a physical change. Examples of physical change include but are not limited to, from solid to liquid or from liquid to gas are also physical changes.

Suppose 10 atoms of carbon (C) react with 20 atoms of oxygen (O). According to the Law of Conservation of Matter, how many atoms will there be in the product of this reaction?(1 point)
A) 20
B) 15
C) 10
D) 30
Answer:
D 30
Explanation:
whenever there is a reaction, the amount of atoms don't change, because matter can't be created or destroyed. Add the carbon and oxygen atoms together
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction. This further means that the amount of matter in the reactant of a reaction must equate that of the products. Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction. Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.Learn more: https://brainly.com/question/24996173?referrer=searchResults
