Would you expect oxygen (O) to react more like sulfur (S) or nitrogen (N)? Support your prediction with evidence .

Answer:

D

Explanation:

it's a star it has gas and makes it own light

Limiting reactant : O₂

Mass of  N₂O₄ produced = 95.83 g

Given

50g nitrous oxide

50g oxygen

Reaction

2N20 + 302 - 2N204

Required

Limiting reactant

mass of N204 produced

Solution

mol N₂O :

[tex]\tt =\dfrac{50}{44}=1.136[/tex]

mol O₂ :

[tex]\tt =\dfrac{50}{32}=1.5625[/tex]

2N₂O+3O₂⇒ 2N₂O₄

ICE method

1.136    1.5625

1.0416  1.5625    1.0416

0.0944    0          1.0416

Limiting reactant : Oxygen-O₂

Mass N₂O₄(MW=92 g/mol) :

[tex]\tt =mol\times MW=1.0416\times 92=95.83~g[/tex]

Hello!

In this case, since the antacid is usually composed by the following bases:

- Calcium, magnesium and aluminum hydroxides.

- Hydrogen sodium carbonate.

- Sodium carbonate.

In such a way, the feasible reactions that undergo when they react with the stomach acid are shown on the attached picture. As you can see, they all have in common the formation of chlorides and water, which are the neutralization products that calm down the acidity as they are neutral.

Explanation:

Stomata is present on the lower epidermal layer that helps gases to move through. The tissue between the upper and lower epidermis of leaves, called the mesophyll, is perfectly designed to carry out intensive photosynthesis.

Since this evolutionary development is so crucial to plant identity, almost all terrestrial plants use the same pores, known as stomata, to absorb carbon dioxide and release oxygen.

Stomata are microscopic openings that are crucial for photosynthesis. They swarm and are plentiful on the plants' surface.

The reason for this high concentration is that they have a lot of chloroplasts, which are the locations for photosynthesis.

Chloroplasts provide oxygen and create energy through photosynthesis to assist plant growth and crop output.

Thus, the mesophyll cells of the leaf contain many of chloroplasts. The tissue between the upper and lower epidermis of leaves, called the mesophyll, is perfectly designed to carry out intensive photosynthesis.

Answer:

0.174kg of Ore are required

Explanation:

The ore of 37.3% in nickel by mass means that in 100g of ore there are 37.3g of nickel. As we need to obtain 65g of nickel we can convert this mass to mass of ore using the conversion factor (100g Ore / 37.3g Nickel) as follows:

65g of nickel * (100g Ore / 37.3g Nickel) = 174g of Ore are needed to have 65.0g of nickel. In kilograms:

174g Ore * (1kg / 1000g) =

Answer: The possible molecular formula will be [tex]CO_2[/tex]

Explanation:

Mass of C= 27.3 g

Mass of O = 72.7 g

Step 1 : convert given masses into moles.

Moles of C =[tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{27.3g}{12g/mole}=2.275moles[/tex]

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{72.7g}{16g/mole}=4.544moles[/tex]

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = [tex]\frac{2.275}{2.275}=1[/tex]

For O =[tex]\frac{4.544}{2.275}=2[/tex]

The ratio of C : O = 1: 2

Hence the empirical formula is [tex]CO_2[/tex]

The possible molecular formula will be=[tex]n\times CO_2[/tex]

An acid and a base which differ from each other by a proton are said to form a conjugate pair. The conjugate base of HSO₃⁻ is SO₃²⁻. The correct option is C.

The entity produced when an acid gives up a proton has a tendency to regain the proton and hence it behaves as a base. It is called the conjugate base of the parent acid.

The entity produced when a base accepts a proton has a tendency to donate the proton and hence behaves as an acid. It is called the conjugate acid of the parent base.

Sulfur dioxide dissolved in water gives sulfurous acid H₂SO₃. The conjugate base of this material contains one proton less i.e, HSO₃⁻ and the conjugate base of the substance bisulfite is SO₃²⁻which is sulfite ion.

Thus the correct option is C.

Answer: If an object is buoyant, then it will  float

Explanation:

Buoyancy is the term which describes a type of force which is also known as the upthrust force. This is an upward force upward force exerted by a fluid that opposes the weight of an immersed object.

The objects which are lighter than water easily float on the water due to the existence of this force and the objects which are heavier than water sink in the water due to the existence of this force.

Thus if an object is buoyant, then it will  float.

The heat produced from 48 g Aluminium = -578

Given

Reaction

2 Al + 3 CuSO4 → 3 Cu + Al2(SO4)3 ∆H = -680 kJ

48 g of Aluminum

Heat released

Solution

mol of Aluminium = mass : Ar Al

mol = 48 g : 27 g/mol

mol = 1.78

From the reaction, heat released for 2 moles Al, so for 1.78 Al, the heat released :

Explanation:

Answer:

837.02 ohms

Explanation:

Step one:

Given data

Frequency= 60Hz

L1= 0.75H

L2= 1.47H

When inductors are connected in series, the total inductance is the sum of the individual inductance

Step two:

Inductor 1

[tex]Xl1= 2\pi fL\\\\Xl1= 2*3.142*60*0.75\\\\Xl1= 282.78 ohms[/tex]

Inductor 2

[tex]Xl2= 2\pi fL\\\\Xl2= 2*3.142*60*1.47\\\\Xl2= 554.24 ohms[/tex]

The total inductance is

=282.78+554.24

=837.02 ohms
