How many atoms are in 0.35 moles of carbon (SHOW WORK)
Answer:
2.108x10²³ atoms
Explanation:
In order to convert from moles (of any substance) to atoms (or molecules), we need to use Avogadro's number: It is the number of units in one mol.
In one mol there are 6.023x10²³ atoms.
0.35 mol * 6.023x10²³ atoms/mol = 2.108x10²³ atoms
Thus, in 0.35 moles of carbon there are 2.108x10²³ atoms.

A) Electromagnetic waves can carry energy through water
B) Electromagnetic waves can travel through empty space.
C) Electromagnetic waves can move through gases faster than other types of energy transfer.
D) Electromagnetic waves can move more energy than any other type of energy transfer.
THE CORRECT ANSWER IS B.
#edge2021
Answer: B) Electromagnetic waves can travel through empty space.
Explanation:
Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.
Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.
Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.

Answer:
2. About 138 g of KI will dissolve in 100 g of water at 10°C
3. 34.5 g of KI will dissolve in 25 g of water
4. The solution is not saturated but is unsaturated
Explanation:
From the graph:
1. KI is more soluble than KCl at 10°C because approximately 138g of KI dissolves at 10°C compared to 30 g of KCl per 100 g of water
2. About 138 g of KI will dissolve in 100 g of water at 10°C
3. 138 g of KI dissolves in 100 g of water at 10°C
In 25 g of water which is 1/4 × 100 g of water, 138/4 g = 34.5 g of KI will dissolve
Therefore, 34.5 g of KI will dissolve in 25 g of water
4.At 20 °C, a saturated solution of NaNO₃ will contain about 88 g of NaNO₃ in 100 g of water.
The solution prepared by the chemist contains 45 g of NaNO₃ in 100 g of water at 20 °C. The amount of solute present in the solution is less thanthe solvent can dissolve at that temperature, therefore, the solution is not saturated.

How many moles would be present in 300 liters of dinitrogen monoxide at
STP?
Answer: 13.4
Explanation: i guessed it and got it correct on ck-12
STP is the standard pressure and temperature condition of the ideal gas. 0.13 moles of dinitrogen monoxide will be present at STP.
What is the ideal gas equation?An ideal gas equation is a relation between the pressure, volume with moles, gas constant, and the temperature of the ideal gas. The ideal gas equation is given by,
[tex]\rm PV = nRT[/tex]
Given at STP,
Pressure = 1 atm
Volume = 300 L
Moles = ?
Gas constant =8.3144598 J per mol per Kelvin
Temperature = 273 K
Substituting values in the ideal gas equation we get:
[tex]\begin{aligned} \rm n &= \rm \dfrac{ PV}{RT}\\\\&= \dfrac{1 \times 300}{273 \times 8.314}\\\\&=0.1321\end{aligned}[/tex]
Therefore, 0.13 moles of dinitrogen monoxide are produced at STP.

Which of the following bonds has the greatest polarity?
P4
Br-Br
Te-F
CI-F
Bond polarity and ionic character go hand in hand: We can say that polarity and ionic character are positively correlated. The classical way to determine either is to compare the electronegativity difference (ΔEN) between the bonding atoms. The greater the difference in electronegativity, the larger the dipole moment, the greater the polarity, and the greater the ionic character of the bond.
The Pauling electronegativity scale, which should be provided in most chemistry texts and is certainly available online, can be used to determine ΔEN. As a very general rule of thumb, an ΔEN that is equal to 2.0 or greater indicates an ionic bond. We don't have to worry about that here, though, since we're only interested in polarity. But this is just some conceptual relation to consider; indeed, ionic bonds can be seen as very polar covalent bonds (or covalent bonds with significant ionic character).
There is no known bond that has a 100% ionic character (ΔEN = 4), i.e., a purely ionic bond. But there are many bonds that we know of with 0% ionic character (ΔEN = 0), i.e., a completely nonpolar bond. We can think about this logically without even knowing specific electronegativity values: If the difference in electronegativity between two bonding atoms is 0, then the two atoms must have equivalent electronegativities. And when can this be the case? Well, atoms from the same element have the same electronegativity. So one case of completely nonpolar bonding would be covalent bonding between atoms of the same element.
In the question given, there are two such cases: P4 and Br-Br. P4 is a tetrahedral molecule composed of four covalently bonded P atoms, each one bearing a lone electron pair and bonded to the other three. With each P having the same electronegativity (ΔEN = 0), no P-P bond in P4 has a dipole moment, and the P4 molecule itself is nonpolar. Br-Br is how bromine is found naturally (as diatomic Br₂); since this is a covalent bond between the atoms of the same element, the ΔEN = 0 and there is no dipole moment. A bromine molecule is completely nonpolar.
Fluorine (F) has the greatest electronegativity among the elements, so whether the Te-F or the Cl-F bond has the greater polarity (i.e., the greater ΔEN) really depends on the electronegativity of Te and Cl.
But let's think about this first. Both Cl and F are halogens; Cl is in the period right below F, and, following periodic trends, Cl itself is quite electronegative. Generally, nonmetals don't form ionic bonds with each other (the underlying reason is complicated and not relevant here, but that notion agrees with ΔEN between any two nonmetals being less than 2.0). Nonmetallic elements can form very polar covalent bonds whose ΔEN is very close to 2.0, however.
Tellurium (Te) is a metalloid that is three periods below F. Electronegativity generally decreases as you go down a group. Even though Te and Cl are not in the same group, the fact that Te is two periods below should give a strong presumption that Te has a lower electronegativity than Cl. Moreover, electronegativity increases you move left to right on the periodic table (that is, as the group number increases); Te is in a group to the left of fluorine's and chlorine's. So, using periodic trends alone, we know that Te is in a group to the left of and below that of Cl, both of which trend toward decreasing electronegativity. Thus, it would be reasonable to assume that Te would have a smaller electronegativity than Cl. And so, the ΔEN of Te-F > ΔEN of Cl-F, which means the Te-F bond should have the greater polarity. And, indeed, this is true using the Pauling scale: The EN of F is 4.0; the EN of Cl is 3.0; and the EN of Te is 2.1.
In all, given that the ΔEN of P-P = 0; ΔEN of Br-Br = 0; ΔEN of Te-F = 1.9; and ΔEN of Cl-F = 1.0; the Te-F bond has the greatest polarity.

A gas initially at 5.48 L, 1.34 atm, and 61 °C undergoes a change so that its final volume and temperature are 1.32 L and 31 °C. What is its final pressure? Assume the number of moles remains unchanged.
atm
Answer:
5.06atm
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (Litres)
V2 = final volume (Litres)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
P1 = 1.34 atm
P2 = ?
V1 = 5.48 L
V2 = 1.32 L
T1 = 61 °C = 61 + 273 = 334K
T2 = 31 °C = 31 + 273 = 304K
Using P1V1/T1 = P2V2/T2
1.34 × 5.48/334 = P2 × 1.32/304
7.34/334 = 1.32P2/304
Cross multiply
334 × 1.32P2 = 304 × 7.34
440.88P2 = 2231.36
P2 = 2231.36/440.88
P2 = 5.06
The final pressure is 5.06atm

The upper part of the mantle is
Hard
OR
Soft
Answer: Hard
Explanation:
The upper part of the mantle is hard as it contains thick rock layers. The mantle's upper layer and the crust make up a brittle and rigid rock that's referred to as the Lithosphere.
The upper mantle starts below the Earth crust and then stops at the start of the lower mantle. We should note that the upper mantle results in the movement of the tectonic plates.
