What mass of ethanol will All
a 250.0 ml container if its
density is 0.789 g/ml?
Answer:
The answer is 197.25 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 = 250 mL
density = 0.789 g/ml
So we have
mass = 250 × 0.789
We have the final answer as
197.25 gHope this helps you

The rows in the periodic table are called periods.
What is true about elements in the same period?
Answer:
elements in the same period have the same number of shells
the period number the element is in, that is the number of shells it has.
What is the relationship between the atomic mass of an element and a mole of that element's atoms?
Answer:
Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).
Explanation:
The relationship between the given terms is provided below throughout the below segment.
One mole of such a component's atomic weights is approximately equivalent to that component's atomic mass. This same atomic mass of the oxygen element, for example, is about 16g. As a result, one mole containing oxygen atoms equals 16g of oxygen ([tex]O_2[/tex]). 1 mole containing oxygen atoms weighs 16g.We can say that,
→ [tex]1 \ mole \ in \ gram \ of \ an \ element = Atomic \ mass \ of \ an \ element[/tex]

the number of protons will tell you what elements it is. T or F plzz help
Answer:
True
Explanation:
There are two ways to tell elements apart from each other: the atomic number or the number of protons. The atomic number tells the number of protons in the element.
For example:
There are two given elements. One has 3 protons and an atomic number of 3 while the other has 7 protons and an atomic number of 7. Which one is Lithium?
Lithium has an atomic number of 3, which means it has three protons, which means Lithium is the one with 3 protons.

Describe how the particle motion is different from state to state.
Answer:
The particles in a gas are moving very quickly in random directions.
The particles in a solid are tightly packed and locked in place, and they are vibrating in their place.
The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other.

A student determines the density of an element to be 2.73 g/cm 3 . If the accepted value is 2.70 grams per cm 3 , what is the student's percent error? Identify the element. What is the boiling of this element in Celsius degree
Answer:
Explanation:
percentage error = error x 100 / correct value
= (2.73 - 2.70) x100 / 2.70
= 1.11 %
The element is Aluminium whose density is 2.702 grams / cc
Boiling point of Aluminium = 2519⁰C .

Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R
Answer:
Unit of resistance is Ω (Omega).
Explanation:
The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :
V = IR
R is resistance
Its unit is Omega and it is represented by Ω.
The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer
What is resistance?Resistance is simply the measure of the opposition to current flow in an electrical circuit.
Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.
V = I × R
Where;
V is the voltage or potential difference. I is the current.R is the resistance.The unit of the electrical resistance is ohm Ω
The symbol of resistance is R.
Hence Option A) Symbol: R, Unit : Ω is the correct answer

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps
The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂
Further explanationEqualization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc. 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product 3. Select the coefficient of the substance with the most complex chemical formula equal to 1Reaction
[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]
1. Coefficient
KClO₃ ⟶ aKCl + bO₂
2. Equation
K ⇒ left =1, right=a ⇒a=1
Cl⇒ left =1, right=a ⇒a=1
O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5
The equation turns into :
KClO₃ ⟶ KCl + 1.5O₂
multiplied by 2
2KClO₃ ⟶ 2KCl + 3O₂
