Answer:
The answer is
63.24 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 62 mL
density = 1.02 g/mL
The mass is
mass = 1.02 × 62
We have the final answer as
63.24 gHope this helps you

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.

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

A.) nebula
B.) asteroid
C.) galaxy
D.) planet
The galaxy is defined as a system of stars, gases, dust, and other matter that orbits a common center of gravity. Thus the correct option is C.
What is a galaxy?A galaxy is generally defined as the massive collection of billions of stars with their solar systems, gas and dust all guarded together by the center of gravity.
It is in the planet earth which is the part of our solar system we all live. The solar system is found to be the part of the galaxy called Milky Way. Our milky way galaxy also contains a supermassive black hole in the center.
There are several types of galaxies which are present in different shapes. Some of them are found to be in spiral shape and some other galaxies are seen as oval shaped and they are known as elliptical galaxies.
There are also some galaxies with irregular shapes and they are seen as blobs. It is the stars that are present inside each galaxies produces light and this massive system comprising of stars, dust gases and the matter are held by the gravity.
Thus the correct option is C- galaxy.

Which of these is a property of a substance that is composed of atoms that are held together by metallic bonds?
It has a low melting point.
It can be flattened and bent.
It cannot be shaped into wires.
It does not conduct electricity.
Answer:
B: it can be flattened and bent
Explanation:
Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.
Metals are bonded together by metallic bonds.
Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.
The property of a substance that is composed of atoms that are held together by metallic bonds is it can be flattened and bent
What is metallic bond ?Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.
The metallic bond is a force of attraction which is responsible for holding the atoms together, releases electrons to achieve the configuration of a noble gas.
in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud
The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them called as "sea of electrons" by cohesive bond.

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

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.
