which best describes the relationship of substance particles in my neutral atom
Answer: The number of protons equals the number of electrons
Explanation:
The statement that describes the relationship of substance particles in my neutral atom is the number of protons equals the number of electrons. The correct option is C.
What are subatomic particles?Subatomic particles are the charged particles that are present inside the atoms. These particles are electron, proton, and neutron. The electron is negatively charged, a proton is positively charged and neutrons neutrally charges subatomic particle.
Neutron atoms are when there is no positive or negative charge present inside the atoms. This could happen when the negatively charged electron and positively charged proton combine, when negative and positive combines they become neutral.
Thus, the correct option is C. the number of protons equals the number of electrons.

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.
Sb2O3 + 3 C --> 2 Sb + 3 CO
40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO
Answer: 40.3 L
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]
[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]
According to stoichiometry :
1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]
Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex] of [tex]CO[/tex]
Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]
Thus 40.3 L of CO is produced.

True or False: If you find the percent by mass of all of the elements in a compound, it will always add up to exactly 100.00%
Answer: true
Explanation: because Mass percentage composition is found by calculating a fraction of the total mass by each element present in a compound. The whole compound itself would equal one or 100% in all the elements that make it up would only be a fraction, so it will always have to add up to 100%

What are the circles around the nucleus called
Answer:
Electron Shells
Outermost level: Valence level
Explanation:
The number of atoms of any element in the given chemical formula is the number that is written on the food of the symbol of that element. The circles around the nucleus called shells or orbits.
What is atom?Atom is the smallest particle of any matter. Atom combines to form element and element combine to form molecule or compound. In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge.
Atom consists of electron, proton and neutron. The total mass of atom is inside the nucleus. Inside the nucleus proton and neutron is there. So calculate mass of an atom, total mass of all protons is added to the total mass of neutron. Electrons revolve around the nucleus in circular path called orbit or shells.
Thus the circles around the nucleus called shells or orbits.

grams of carbon?
a 55 g
b 73 g
c 64 g
d 88 g
Answer:
c. 64 grams
Explanation:
What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.

steam at130˚C.
Answer:
How much heat energy required to convert following?
How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?
Specific Heat of Ice - 2.09 j/g * c
This is how I did it and the answer is wrong...Please check and correct me
Q = m * Cice * Change in Temp
Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj
On the moon,When dropped from the same height Why does a flat sheet of paper fall more slowly than the same sheet when it is tightly crumpled into a ball?
Answer:
It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

Mr. Keans's class is doing a lab to determine the identity of an unknown metal. Use the table to help determine
the identity of a metal that has a mass of 89 grams and occupies 10 cm of space.
O Nickel
O Silver
O Lead
O Mercury
Answer:
[tex]\boxed {\boxed {\sf A. \ Nickel}}[/tex]
Explanation:
First, we must find the density of the unknown metal.
Density is found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the metal is 89 grams and the density is 10 cubic centimeters.
[tex]m= 89 \ g \\d= 10 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac{89 \ g}{10 \ cm^3}[/tex]
Divide.
[tex]d= 8.9 \ g/cm^3[/tex]
Now we know the density and can identify the unknown metal.
Nickel: 8.9 g/cm³Silver: 10.5 g/cm³Lead: 11.35 g/cm³Mercury: 13.55 g/cm³The density matches nickel's density. Therefore, this metal must be nickel.

Darryl finds a bottle of what looks like clear water, with dirt settled at the bottom. When he shakes the bottle, the water gets dirty. Which term best describes the matter in the bottle?
A.homogeneous mixture
B.heterogeneous mixture
C.element
D.compound
Answer:
The correct answer is Heterogeneous mixture
Explanation:
Heterogeneous mixture are those mixture in which:
Substance is distributed in non uniform manner.
Two distinct layers are formed
Thus when water and dirt are mixed together it results in the formation of a heterogeneous mixture and after sometimes two different layers will be observed.
Hence, in the bottle there is a heterogeneous mixture of water and dirt.

what volume of water has a mass of 1 kg
Answer:
[tex]V=0.001\ m^3[/tex]
Explanation:
Mass, m = 1 kg
The density of water, d = 1000 kg/m³
We need to find the volume of water. The formula for the density of an object is equal to mass divided by volume. Its formula is :
d = m/V
V is the volume of water
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{1\ kg}{1000\ kg/m^3}\\\\=0.001\ m^3[/tex]
So, the volume of water is [tex]0.001\ m^3[/tex].
Answer:
Volume of water has a mass of 1 kg is explained below in details.
Explanation:
One liter of h2O has a volume of approximately specifically one kilogram when estimated at its maximum frequency, which happens at about 4 °C. It observes, therefore, that thousand of a liter, recognized as one milliliter (1 mL), of h2O has a volume of about 1 g; 1000 liters of h2O has a volume of about 1000 kg (1 tonne).
