How many grams of Al are needed to react with 91.8 grams of FeO
3FeO + 2Al —> 3 Fe +Al2O3

Answers

Answer:

Ans : 22.86 gm of Aluminium

Solution,

                        3FeO + 2Al ---> 3 Fe + [tex]Al_{2}O_{3}[/tex]

Given                   3          2                    

Find                    1.27       x

By the given gms of FeO find its mole and put the moles in the find,

                         

                                       [tex]n = \frac{given mass}{molecular mass}[/tex]

                  Given mass of FeO is 91.8

                   Molecular mass of FeO is 71.8

                                           

                                         n = [tex]\frac{91.8}{71.8}[/tex]  

                                         n = 1.27 moles of FeO  

Now solve for x,

                            [tex]x = \frac{2 x 1.27}{71.8}[/tex]

                             x = 0.85 moles

These are just moles of Aluminium that we need to react with FeO, so to find Grams of Aluminium we need,

                                Mass = moles x molecular mass

                                Mass = 0.85 x 27(atomic mass of Al)

                                Mass = 22.86 grams of aluminium is what we need

electrons.

Answers

Answer:

Magnesium forms a positive ion and wants to lose electrons. Bromine forms a negative ion and wants to gain electrons.

Answer:

Magnesium forms a positive ion (Mg²+) and wants to lose two electrons.

Bromine forms a stable noble gas electronic

configuration when it gains one electron. Thus we find

magnesium as 2+ cation and bromine as a 1- anion in a

1:2 ratio in the compound .

Also, bromine forms a negative ion.

Answers

Answer:

D

Explanation:

According to this question, each model of molecules in the options contains spheres of different colors and sizes representing different types of atoms. The atoms of the same element are the spheres of same color and size while atoms of different element are of different color or size.

Therefore, the model showing a molecule of a substance that is made up of three elements is model D because it is made up of three distinct spheres representing atoms of each element.

- The red sphere is the atom of the first element

- The big dark sphere is the atom of the second element

- The small white sphere is the atom of the third element

Answers

Answer:

Argon {Ar}

Explanation:

The noble gas used for a condensed electron configuration is the one before the element which you are configuring.

In this case, the element (Mn) is manganese

The noble gas that is before this element is Argon which is the row above it

so your configuration would be {Ar} 3d^5 4s^2

Which phrase describes neap tides?
A.) occur four times a day
B.) produce extra-low tidal ranges
C.) caused only by the pull of the moon
D.) occur at the same time as spring tides

NEED YOUR HELP.

Answers

Answer:

The answer is B

Explanation:

Neap tides are a type of to tie occuring after spring tides. It occurs when moon and sun are at the right angles to each other. It produce low tidal ranges. Hence, phrase B is correct.

What are tides ?

Tides are a geographical phenomenon taking place due to the gravitational pull by sun and moon on the ocean of earth. They are long period waves causing the ocean back and forth to the cost.

During new moons larger tides appears in earth and they are called spring tides. Spring tides occurs twice in a lunar month. During spring tides, moon appears full and earth is between sun and moon.

After seven days of spring tide, lower tides are produced when the moo and sun comes in right angle to each other. They are called the neap tides producing lower range of tidal waves . During this time moon will be half full thus for the first and last quarter of the moon. Hence, the option B neap tide produce low tidal ranges is correct.

a typical baseball has a mass of 350g and takes up a volume of .780L. what is the density of a baseball in g/l and g/ml?

Answers

Answer:

449 g/L

0.449 g/mL

Explanation:

Step 1: Given data

Mass of a typical baseball (m): 350 gVolume of a typical baseball (V): 0.780 L

Step 2: Calculate the density (ρ) of the baseball in g/L

The density is equal to the quotient between the mass and the volume.

ρ = m / V

ρ = 350 g / 0.780 L

ρ =449 g/L

Step 3: Convert ρ from "g/L" to "g/mL"

We will use the conversion factor 1 L = 1000 mL.

449 g/L × (1 L/1000 mL) = 0.449 g/mL

Why is the primary standard, KHP, used in the determination of the molar mass of an acid?

Answers

Potassium acid phthalate will serve as our primary standard. This is a large molecule (KHC8H4O4) with a molar mass of 204.2 g/mol. Instead of writing the whole formula, we abbreviate it as KHP, where "P" stands for the phthalate ion, C8H4O42-, not for phosphorus. KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. Therefore, KHP is monoprotic and will react with NaOH in a simple 1 to 1 relationship according to the following equation:

What is the law of conservation of matter?
A.Matter can never be changed.
B.Matter can never mix or rearrange.
C.Matter cannot be created or destroyed.
D.matter will always break down.

Answers

Considering the definition of the law of conservation of matter, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

Law of conservation of matter

The law of conservation of matter holds that, within a closed system, the amount of matter involved in a chemical reaction is constant, meaning a closed system means an environment that isolates the components involved in the reaction from the outside.

In other words, this law establishes that the mass of the reactants consumed is equal to the mass of the products obtained, even though they have been transformed into each other.

In other words, the law of conservation of matter states that matter is neither created nor destroyed during a chemical reaction, it is only transformed.

Summary

In summary, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

Answers

Answer:

hope it helped you.

Explanation:

The properties of matter that do not depend on the size or quantity of matter in any way are referred to as an intensive property of matter. Temperatures, density, color, melting and boiling point, etc., all are intensive property as they will not change with a change in size or quantity of matter.

An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Other intensive properties include color, temperature, density, and solubility.

2. The new element Odessium (Od) was discovered in 2020 by Mr. Green. It has three isotopes: Od-284
(34.60%), Od-285 (21.20%), and Od-288 (44.20%). What is its average atomic mass?|

Answers

Answer:

Odessium (Od) has an average atomic mass of 284.45

Explanation:

Average mass is calculated from the isotopes of an element weighted by their relative abundance.

To calculate the relative average mass, you need to find the % of each isotope and use these to calculate the relative average mass

(34.60 %)/100 x 284=96.73(21.20 %)/100 x 285=60.42(44.20 %)/ 100 x 288=127.296

Add all 3 answers to get the relative average mass

96.73 + 60.42 + 127.296= 284.45
