Question: Based on this information, which type of light is more likely to damage the material?

1)The gamma ray light is more likely to damage the material because the gamma ray light can
pull energy out of the material when it passes through the material.
b
2)The X-ray light is more likely to damage the material because the X-ray light bounces off of
the material, which means that it has more energy.

3)There is no way to know because they are two different types of light, and different types of
light can change a material in different ways.

4)Neither type of light is likely to damage the material because the material does not take in
energy from either the X-ray light or the gamma ray light.

A

add a coefficient 2 before Fe and a 3 before H2O

Answer:

Option A. Add a coefficient 2 before Fe and a 3 before H2O

Explanation:

Fe₂O₃ + 3H₂ —> Fe + H₂O

The above equation can be balance by as follow:

Fe₂O₃ + 3H₂ —> Fe + H₂O

There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by putting 2 before Fe as shown below:

Fe₂O₃ + 3H₂ —> 2Fe + H₂O

There are 3 atoms of O on the left side and 1 atom on the right side. It can be balance by putting 3 before H₂O as shown below:

Fe₂O₃ + 3H₂ —> 2Fe + 3H₂O

Now the equation is balanced.

Thus, the student should add a coefficient 2 before Fe and a 3 before H2O

Answer:

what is the question i could help if u gave me the question but i don't see it  

Explanation:

what are the following things

Metals are good conductors and shows some peculiarities such as luster, ductility, malleability,etc. Brittleness is not associated with metals since they are hard. Hence option A is correct.

Metals are electropositive elements with good conductivity. Metals are classified into the s block and d block of periodic table. Thus alkali metals, alkaline earth metals and transition metals are the classes of metals.

Metals are rich in free electrons thereby, they capable of conducting electrically and thermally. Other features that metals have , they are hard and not brittle. Metals are malleable and ductile.

Malleability is the property by which it can be pressed into different shapes easily without cracking. Ductility means they can be plastically deformed into thin wires without fracture.

Metals are shining and this property is called lustrous. Hence all the properties such malleability, ductility and luster are features of metals but they are not brittle. Hence option A is correct.

Explanation:

3Mg(s) + N2(g) = Mg3N2(s)

First check that the equation is balanced. In this case, it is.

Assuming that magnesium is the limiting reactant:

       We find that the atomic mass of magnesium is approximately

       24.3g, so the molecular weight is just 24.3g\mol

    2. Next we need the mole to mole ratio. As there are 3

        magnesiums for 1 magnesium nitride (shown by the coefficients), the                    

        mole to mole ratio is 1 mol Mg3N2\3 mol Mg.

    3. We need the amount of the substance, in grams. Since you have not    

        stated it in the question, I'll just do 10g AS AN EXAMPLE. Note that    

       depending on the amount, the LIMITING REAGENT MAY DIFFER.

   4.  Finally, we need the molecular weight of Mg3N2, which we can easily    

        calculate to be around 100.9\mol.

   5.  Putting this all together, we have 10gMg⋅ (mol Mg\24.3gMg)

        (1mol Mg3N2\ 3mol Mg) (100.9g Mg3N2\mol Mg3N2)

        the units will cancel to leave gMg3N2 (grams of magnesium nitride):

       10gMg ⋅ (mol Mg\24.3gMg) (1mol Mg3N2\3mol Mg)

       (100.9g Mg3N2\mol Mg3N2)

Doing the calculation yields approximately 13.84g.

Assuming that nitrogen is the limiting reactant:

Similarly, following the above steps but with 10g of nitrogen yields 36.04g

In conclusion, as we produce less amount of Mg3N2 when we assumed that Mg was the limiting reagent, magnesium is the limiting reagent and nitrogen is the excess.

Note: This is in THIS CASE, where we have 10g of both. The answer may vary depending on the amount of each substance.

Answer:

  1.46×10^25 molecules

Explanation:

Each mole of N₂ reacts with 3 moles of Mg to form 1 mole of Mg₃N₂. That is, the number of moles of product is equal to the number of moles of nitrogen gas when excess magnesium is present.

There are 6.022×10²³ molecules in each mole of a substance, so the number of molecules of Mg₃N₂ is

  (24.3 mol)(6.022×10²³ molecules/mol) = 1.46×10²⁵ molecules

Explanation:

Im really sorry if this is wrong. Im d u m b

Explanation:

The more reactive element replaces less reactive element during chemical reaction.

Since, potassium is more reactive than beryllium. When potassium reacts with beryllium choride, it replaces beryllium and forms potassium chloride and produces beryllium.

Beryllium is produced due to the fact that the more reactive element in the reaction would have to take over the element that is less reactive.

In this reaction the element that is more reactive is potassium. When the reaction takes place it would take over and replace beryllium due to this quality.

Hence beryllium chloride would become potassium chloride from the resulting reaction.

Answer:

228.7[tex]dm^{3}[/tex]

Explanation:

According to Boyle's law

P1V1 = P2V2

where P1& P2 are initial and final pressure

and V1& V2 and initial and final volumes respectively.

Given:

P1 = 136atm, P2 = 131.6atm

V1 = 142[tex]dm^{3}[/tex]; V2 = ?

V2 = [tex]\frac{P1V1}{P2}[/tex] = [tex]\frac{136*142}{131.6}[/tex]

= 146.7[tex]dm^{3}[/tex]

Total volume, V = V1 + V2

=146.7 + 142

= 228.7[tex]dm^{3}[/tex]

Answer:

do not care

Explanation:

1. 12 L = 12 dm³

2. 3.18 g

Given

1. Reaction

K₂CO₃+2HNO₃⇒ 2KNO₃+H₂O+CO₂

69 g K₂CO₃

2. 0.03 mol/L Na₂CO₃

Required

1. volume of CO₂

2. mass Na₂CO₃

Solution

1. mol K₂CO₃(MW=138 g/mol) :

= 69 : 138

= 0.5

mol ratio of K₂CO₃ : CO₂ = 1 : 1, so mol CO₂ = 0.5

Assume at RTP(25 C, 1 atm) 1 mol gas = 24 L, so volume CO₂ :

= 0.5 x 24 L

= 12 L

2. M Na₂CO₃ = 0.03 M

Volume = 1 L

mol Na₂CO₃ :

= M x V

= 0.03 x 1

= 0.03 moles

Mass Na₂CO₃(MW=106 g/mol) :

= mol x MW

= 0.03 x 106

= 3.18 g

Fossil Fuels are exhaustible natural resources, because they can't be renewed. Once these fuels are used up, there are NONE left! We can change that by reducing the amount we use. It takes millions of years for it to be remade, and we will soon die out before that happens. Thats why fossil fuels are exhaustible. :)
