Answer:
370 cm^3
Explanation:
Here, Density= Mass / Volume
=1.00/370
=370 cm^3.
The density of the metal is approximately 2.70 kg/dm³.
Density (ρ) is calculated by dividing the mass (m) of an object by its volume (V): ρ = m/V.
Given:
Mass (m) = 1.00 kg
Volume (V) = 370 cm³ = 0.370 dm³
Density (ρ) = 1.00 kg / 0.370 dm³ ≈ 2.70 kg/dm³
The density of the metal is approximately 2.70 kg/dm³.
Density is a measure of how much mass is contained within a given volume. In this case, a metal with a mass of 1.00 kg occupies a volume of 370 cm³.
By dividing the mass by the volume, the density is calculated. The resulting value of 2.70 kg/dm³ indicates that for every cubic decimeter (dm³) of volume, the metal has a mass of 2.70 kg.

Write balanced, net ionic equations for the reactions shown below. Identify the spectator ions. (40
points possible: 8 points per problem = 4 points for net ionic equation, 4 points for spectator ions)
a. Sr(NO3)2 (aq) + H2SO4 (aq) → SrSO4 (s) + 2HNO3 (aq)
Taking into account the definition of net ionic equation, the net ionic equation is Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) and H⁺ and NO₃⁻ are the spectator ions.
The net ionic equation is a chemical equation for a reaction that lists only the species that participate in the reaction.
In other words, an ionic equation is a chemical equation where electrolytes in aqueous solution are written as dissociated ions. Usually this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation, to indicate that they are in aqueous solution.
The balanced equation will be:
Sr(NO₃)₂ (aq) + H₂SO₄ (aq) → SrSO₄ (s) + 2 HNO₃ (aq)
where (aq) means aqueous and (s) solid.
Taking into account that:
All salts of NO₃⁻, C₂H₃O₂⁻, ClO₃⁻ and ClO₄⁻ are soluble.The total ionic equation in separated aqueous solution will be:
Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 H⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) + 2 NO₃⁻(aq) + 2 H⁺(aq)
A spectator ion is an ion that appears both as a reactant and as a product in an ionic equation.
Spectator ions can be either cations (positively charged ions) or anions (negatively charged ions).
When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.
In this case, H⁺ and NO₃⁻ are the spectator ions because they appear unchanged in both the product and the reagent. So these ions cancel out by writing the net ionic equation and you get:
Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s)
In summary, the net ionic equation is Sr²⁺(aq) + 2 SO₄⁻(aq) → SrSO₄ (s) and H⁺ and NO₃⁻ are the spectator ions.

Explanation:
The total charge in a compound must be 0. Explain how this is possible when the anions and cations do not have equal and opposite charges, such as in magnesium chloride and aluminum oxide. ???
The two chlorine atoms have a total charge of -2 hence the total charge in the compound is zero. Three oxygen atoms each having a charge of -2 making a total charge of -6 hence the total charge in the compound is zero.
In magnesium chloride, magnesium has a charge of +2. Chlorine has a charge of +1. However, in the compound, there are two chlorine atoms and one magnesium atom. As such, the two chlorine atoms have a total charge of -2 hence the total charge in the compound is zero.
In Aluminium oxide (Al2O3), there are two aluminium atoms having a total charge of +6. There are three oxygen atoms each having a charge of -2 making a total charge of -6 hence the total charge in the compound is zero.

Claire is a middle school student on her way to school one day she saw a puddle in the road when she returns home after school the puddle was gone what happens to the water in the puddle
The water in the puddle had vanished, leaving nothing behind. Water moves from the Earth's surface to the atmosphere via evaporation.
What is evaporation ?A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day or when wet clothing dries in the sun.
In these instances, the liquid water is evaporating into a gas known as water vapor rather than really dissipating. Global evaporation takes place.
Heat energy causes the bonds holding the water molecules together to fall apart, which causes evaporation. On the stove, adding heat to liquid water is what you do when you boil water.
Steam is created when water changes from a liquid form to a gaseous state (water vapor) due to the bonding being broken by the additional heat.
Thus, evaporation takes place in this process.

Using what you can recall from this unit, write one or two short paragraphs describing John Dalton’s atomic model. If needed, search the Internet for descriptions of the model.
Answer:
Five points of Dalton's atomic theory:
1) all elements are made up of atoms.
2) atoms are so small that they cannot be divided any further.
3) an atom can neither be destroyed nor be formed.
4) atoms of an element are similar, they possess the same mass and same properties.
5) atoms of different elements combine in a definite ratio to form compounds.
Due to further experimentation, it was concluded that an atom is made up of small particles identified as protons, neutrons, and electrons. They can be further subdivided.
Another change is the presence of isotopes of atoms of different elements. Hence, atoms of the same element can also have different masses.

What is Dalton's atomic model?
Dalton proposed that the concept of atoms may be used to explain the laws of conservation of mass as well as definite proportions. He proposed that atoms, of the kind, that he described as "solid, tightly compacted, hard, impenetrable, moving particle," are the smallest, indivisible units of matter.

Which characteristic do electronegativity differences indicate about reactions between atoms
O bond number
O compound energy storage
O valence electron number
O bond type
Answer:
valence electron number
Explanation:
trust me
Valence electron number is the characteristic do electronegativity differences indicate about reactions between atoms. Hence option C is correct.
What is electronegativity?Electronegativity is defined as the propensity for atoms involved in covalent bonds to draw the bonding electrons. An indicator of how strongly atoms draw bonding electrons to them is their electronegativity. How polar a bond is depends on the difference in electronegativity between two atoms. Since there is no difference in electronegativity between the two identical atoms in a diatomic molecule, the bond is nonpolar or pure covalent.
Valence electron number is defined as an atom's associated outer shell electron that, if the outer shell is open, can take part in the formation of a chemical bond.
Thus, valence electron number is the characteristic do electronegativity differences indicate about reactions between atoms. Hence option C is correct.
