Answer:
A divergent boundary!
Explanation:
A divergent boundary occurs when two plates move away from each other, while a convergent boundary is when two plated collide. And a transform plate boundary is when two plates horizontally slide against each other.

how many mongo seed are equal to 3.50 moles of mongo seeds?
answer:
2.107 x 10^24 mongo seeds
Answer:
50 moles of many mango seeds = 2.107.10²⁴ mango
Further explanation
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule
With Avogadro's number
N = number of gas particles
No = Avogadro number (6.02.10²³)
n = number of moles
n= N/No
3.50 moles of many mango seeds are comparable to
N mango seeds= 3.5 x 6.02.10²³
N mango seeds=2.107 x 10²⁴..

Chlorine reacts very violently. What about its electron shells makes this the case?
Answer:
it readily gains another electron. the outer electron shell is closer to the nucleus, than iodine for example, which makes it less shielded (greater attraction for another electron = violent reaction to get it)

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
Answer:
5.5 L
Explanation:
First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:
10 g ÷ 44 g/mol = 0.23 molThen we use the PV=nRT formula, where:
P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K
V = 5.5 LWhich changes would cause an increase in the resistance of a wire? Check all that apply.

Wendy wants to find out if a substance is an acid or a base. What are two ways that Wendy could
investigate to find out what kind of substance it is?
Without tasting a colorless liquid, an acid or a base can be determined using indicators.
The three most common indicators to test for acids and bases are: Litmus. Methyl orange. Phenolphthalein.
How do you know something is an acid?One practical method for determining how acidic something is is to use the pH scale. A solution is acidic if its pH is less than 7. If the pH of the solution is 7, it is neutral; if the pH is greater than 7, it is basic.To identify acids and bases, two types of litmus paper are available: red litmus paper and blue litmus paper. When exposed to acidic conditions, blue litmus paper turns red, while red litmus paper turns blue when exposed to basic or alkaline conditions.

What type of weathering creates a granite Tor?
Physical or
Chemical or
Biological
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.
If one of the cars began with 5.6 liters of gasoline and oxygen, how much water and carbon dioxide do you think would be produced from that gasoline and oxygen?
Answer
5.6 L
Explanation:
whatever you start with, you end with the same amount.
(LAW OF CONSERVATION)
The amount of oxygen and gasoline that can be produced is 5.6 liters
The question above is answered with the law of conversation of mass. This law of conversation of mass states that no form of energy can be destroyed, instead it is changed from one form to another type of form.
In this law, it is expected that you end with the same amount you started with. According to the question above, since the amount that you started with is 5.6 liters then you will end with 5.6 liters also.

please help me out i will give you brainlist. 0.500 is wrong
============================================
Work Shown:
Using the periodic table, we see that
1 mole of carbon = 12 grams1 mole of oxygen = 16 gramsThese are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.
So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.
-------------------
Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.
11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2
In short,
11.0 grams of CO2 = 0.250 mol of CO2
This is approximate.
We don't need to use any of the information in the table.

how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).

In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder and the water level increases from 28.2 mL to 31.4 mL. What is the density of the metal ball? (round you answer to the nearest hundredth)
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml
the empirical formula is C6H6O.vapour density is 47.find the molecular formula
Answer: The molecular formula will be [tex]C_6H_6O[/tex]
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The empirical formula is [tex]C_6H_6O[/tex]
The empirical weight of [tex]C_6H_6O[/tex] = 6(12)+6(1)+1(16) = 94 g.
The molecular weight = [tex]2\times \text{vapour density}=2\times 47=94[/tex]
Now we have to calculate the molecular formula.
[tex]n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{94}{94}=1[/tex]
The molecular formula will be=[tex]1\times C_6H_6O=C_6H_6O[/tex]
