Answers
Answer:
24 g of oxygen
Explanation:
The equations means that four moles of CH3NO2 reacts with three moles of oxygen to yield for moles of carbon dioxide, two moles of nitrogen gas and six moles of water.
The balanced equation of the reaction is;
4CH3NO2 + 3O2 -----> 4CO2 + 2N2 + 6H2O
Molar mass of CH3NO2 = 61 g/mol
61 g of methyl nitrate contains 61 g/ 61 g/mol = 1 mole of CH3NO2
From the balanced reaction equation;
4 moles of CH3NO2 reacts with 3 moles of oxygen
1 mole of moles of CH3NO2 reacts with 1 * 3/4 = 0.75 moles of oxygen gas
0.75 moles of oxygen gas * 32 g/mol = 24 g of oxygen

what ions are formed when sodium reacts with fluorine
Answers
Answer:
One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it.
Explanation:
Na + F₂ --> NaF
This is an ionic bond formation NaF from sodium atom and fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it.

Which statement correctly compares electric charge with electric current?
A.
They both require a human to make them.
B. Neither require charged particles.
C. They both require a battery and a bulb
D. They both require a movement of charged particles.
Answers
Answer:
Your answer would be D) They both require a movement of charged particles
Explanation:
In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use

Since protons (p+) with a positive charge and neutrons (n0) without a charge are located in the nucleus, what is the overall charge of the nucleus portion of an atom: positive, negative, or no charge at all? Explain.
Answers
Answer:
Positive
Explanation:
The nucleus of an atom has a net positive charge which is balanced by the negative charge of the electrons residing in the orbital of an atom. The reason why the nucleus of an atom is positively charged is because it contains two sub atomic particles;
The protons and neutrons. In terms of charge, the proton is positively charged and the neutron is neutral. This means the neutron does not partake in the charge of the nucleus. Hence the net charge of the nucleus is decided by the protons which are positively charged

A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?
Answers
Answer:
0.706 L (Liters)
Explanation:
P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X
T1 T2 290 K 273 K
706 mL = X
According to the question,
Pressure,
Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]Temperature,
Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]Volume,
Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]By using the Boyl's and Charl's combination law, we get
→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
or,
→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]
By putting the values, we get
→ [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]
→ [tex]= 706 \ L[/tex]
Thus the aforementioned answer is right.

if surface tension relies on intermolecular forces, how could you make surface tension decrease?
(think about how and where molecules bind to each other)
Answers
Answer:
We could make the surface tension to decrease by removing and causing a disruption to the intermolecular forces(hydrogen bonds).
Explanation:
To explain this answer, we will consider an experiment whereby a paper clip is made to rest at the top surface of water inside a container/beaker.
First of all, the intermolecular forces present in water are also known as hydrogen bonds.
It's relationship with surface tension is that when there is high surface tension in the water, this high tension will allow the paper clip to rest on top of the hydrogen bonds present at the top surface in between the water molecules.
However, the surface tension will decrease when we remove or cause a disruption to the intermolecular forces (hydrogen bonds).

Explanation:
The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.
First we convert molecules into moles by using Avogadro's number:
4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 molNow we convert moles of sucrose into grams, using its molar mass:

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass
Answers
step by step explanation:
D= M/V
M= DV
M= (13.6 g/cm^3) (825cm^3)
M= 11,200 g
The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.
What is density ?Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.
Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.
Give that, volume of the object = 825 cm³
density = 13.6 g/cm³
Mass = volume × density
m = 825 cm³ × 13.6 g/cm³ = 11220 g
Therefore, the mass of the object is 11220 g.
