Select the correct balanced equation for the combustion of methane.
CH4 + 02 -> CO 2 + H2O

Answers

Answer:

A: CH4 + 2O2 -> CO2 + 2H2O

Explanation:

CH4 + O2 -> CO2 + H2O

Count how many elements they are in all molecules for the reactants and for the products.

For the reactants:

C = 1 element

H = 4 elements

O = 2 elements

For the products:

C = 1 element

O = 2 elements

H = 2 elements

O = 1 element

2 oxygen atoms + 1 oxygen atoms = 3 oxygen atoms total on the products side.

To balance this equation, we need to add 2 more elements of hydrogen and 2 more elements of oxygen. Therefore, we add a 2 to the coefficient of O2 for the reactants side and add a 2 to the coefficient of H2O for the products side.

Now let us try it.

CH4 + 2O2 -> CO2 + 2H2O

Count how many elements they are in all molecules for the reactants and products.

For the reactants:

C = 1 element

H = 4 elements

O = 4 elements

For the products:

C = 1 element

O = 2 elements

H = 4 elements

O = 2 elements

2 oxygen atoms + 2 oxygen atoms = 4 oxygen atoms total on the products.

All of the elements are balanced.

So the final answer is A: CH4 + 2O2 -> CO2 + 2H2O

Tim and Jose are moving furniture. Tim pushes a 150 kg sofa with 300N
force. As a result, Sofa’s acceleration was __________ according to Newton’s
Second Law of motion. (F = ma)

Answers

Answer:

a = 2m/s²

Explanation:

Given data:

Mass of sofa = 150 Kg

Force applied = 300 N

Acceleration = ?

Solution:

Formula:

F = ma

F = force

m = mass

a = acceleration

by putting values,

300 N = 150 Kg × a

a =  300 N /150 Kg

a = 300 Kg m/s² / 150 Kg   ( N = Kgm/s²)

a = 2m/s²

2 NaOH (s) + CO2(g) → Na2CO3 (s) + H20 (I) How many grams of water can be produced with 1.85 moles of NaOH​

Answers

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Moles of H2O = 1.85mol * (1/2) = 0.925mol.

Mass of H2O = 0.925mol * (18g/mol) = 16.65g.

Answer:

16.65 grams of water can be produced with 1.85 moles of NaOH.

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Number of moles of water = (1/2)×1.85= 0.925 moles

Molar mass of water (H2O) = 18g/mol

Mass of the right water = 18g/mol×0.925 mol=16.65 grams

Leopard seals are animals adapted to survive in the freezing conditions of Antarctica. Individual leopard seals vary in their different traits.
Which of the following variations would give a leopard seal the greatest chance of surviving in its harsh environment?
A. More spots on its coat. B. Thicker layer of blubber
C. More elongated head
D. Wider, flatter teeth

Answers

Answer:

B. Thicker layer of blubber

Explanation:

For the leopard seals to survives this harsh environment, it must have a thicker layer of blubber

Blubber is a thick layer of fat. It is called the adipose tissues and found in most marine organisms.

This layer helps in insulating the body against heat loss. By so doing, the animal is able to conserve internal heat. They have low thermal conductivity and do not easily lose heat or gain heat as such.

What is electromagnetic wave ?

The electromagnetic field's waves, which travel through space and convey electromagnetic radiant energy, are what make up electromagnetic radiation. It consists of X-rays, gamma rays, microwaves, infrared, light, and radio waves. These waves are all a component of the electromagnetic spectrum.

There are seven different kinds of them are X-rays, gamma rays, visible light, infrared light, radio waves, and microwaves. They may be compared to seven distinct types of light.

Lower frequency electromagnetic radiation than microwaves is referred to be a radio wave. Radio waves have wavelengths that range from tens of thousands of meters to 30 centimeters. These are equivalent to frequencies between 3 Hz and 1 GHz (109 Hz).

Explanation:

Hope this helps

To find the mass in grams of Cesium that would remain after disintegration, we would be applying the formula:

N(t) = [tex]N_{0} (\frac{1}{2})^{\frac{t}{t{\frac{1}{2} } }[/tex]

       where:

      [tex]N_{0}[/tex] = Initial quantity of the sample = 1.0g

       t = time in years of disintegration = 90 years

      [tex]t\frac{1}{2}[/tex] = Half life of cesium isotope = 30 years

      N(t) = Quantity of substance after disintegration = ?

Solving for N(t)

N(t) =  [tex]1 ( \frac{1}{2})^ \frac{90}{30}[/tex]

N(t) =  [tex]1 (\frac{1}{2})^{3}[/tex]

N(t) = 0.125 grams

Therefore, the quantity of cesium-137 that would remain after disintegrating over a period of 90 years is 0.125 grams.

Explanation:

From the question given above, we obtained the following equation:

4NaOH + 4HCl —> NaCl + H₂O

The equation can be balance as follow:

4NaOH + 4HCl —> NaCl + H₂O

There are 4 atoms of Na on the left side and 1 atom on the right side. It can be balance by putting 4 in front of NaCl as shown below:

4NaOH + 4HCl —> 4NaCl + H₂O

There are a total of 8 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 4 in front of H₂O as shown below:

4NaOH + 4HCl —> 4NaCl + 4H₂O

Next, divide through by 4 to express the equation with the lowest coefficients.

NaOH + HCl —> NaCl + H₂O

Now the equation is balanced.

CH3COOH is an accepted and common form of writing the structure of acetic acid (commonly known as vinegar when diluted in water).

Sulfur dioxide, SO2, is used in wine as an antioxidant, slowing the oxidation of ethanol
to ethanoic acid. To determine the SO2 content of a wine sample, sodium hydroxide
and sulfuric acid were added to ensure that all sulfur was present as SO2. A 20.00 mL
aliquot was then titrated against standardised iodine solution, using starch indicator.
Reaction occurred according to the equation:
SO2(aq) + 2H2O(l) + 12(aq) → 4H+ (aq) + 21- (aq) + SO42- (aq)
The end point was reached with 15.62 mL of 0.00501 M iodine solution. The

Answers

The  concentration (in M) of SO₂ in the wine : c. 3.9 x 10⁻³

SO2(aq) + 2H2O(l) + I2(aq) → 4H+ (aq) + 21- (aq) + SO42- (aq)

Required

The  concentration (in M) of SO2

Solution

Titration ⇒ mol SO₂ = mol iodine(I)

mol iodine :

=15.62 ml x 0.00501 M

=0.078256 mlmol

From equation, mol ratio of of SO₂ : I₂ = 1 : 1, so mol SO₂=0.078256

The concentration of SO₂(in 20 ml sample) :

M = n/V

M = 0.078256 mlmol/20 ml

M = 0.0039128

Determine the oxidation number of
Sulphur in Sodium thiosulphate​

Answers

The oxidation number of  Sulphur = +2

Further explanation

General formula for determining Oxidation Numbers :

1. The number of oxidation of single element atoms = 0. Examples of Ar, Mg, Cu, Fe, N₂, O₂, etc. = 0

Group I : +1

Group II : +2

H in compound = +1, except metal hydride compounds (Hydrogen which binds I or II groups) oxidation number H = -1, for example, LiH, MgH₂, etc.

2. Oxidation number O in compound = -2, except OF2 = + 2 and in peroxide (Na₂O₂, BaO₂) = -1 and superoxide, for example KO₂ = -1/2.

3 The oxidation number in a non-filled compound = 0,

The total amount of oxidation in ion = ion charge, Example NO₃⁻ = -1

Sodium thiosulphate​ - Na₂S₂O₃

Oxidation number Na = +1 ⇒x2 = +2

Oxidation number O = -2 ⇒x3 = -6

Oxidation number Na₂S₂O₃ = 0

2.Na+2.S+3.O=0

2.+1+2.S+3.(-2)=0

2+2S-6=0

-4+2S=0

If I have 45 liters of helium in a balloon at 25°C and increase the
temperature of the balloon to 55° C, what will the new volume of the
balloon be?

Answers

Answer:

52.8 Liters

Explanation:

Gay-Lussacs law states that P1/T1 = P2/T2

if:

P1 = 45T1 (in Kelvins) = 25 + 273.1 =298.1P2= ?T2 = 55 + 273.1 = 328.1

then:

45/298.1 = P2/328.1

P2 = 52.8

The new volume of the balloon is 52.8 Liters this can be calculated by using gas laws.

Charles law:

Charles law states the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature. It is given by

V₁/T₁ = V₂/T₂

What information do we have?

V₁ = 45 L

T₁ = 25 + 273.1 =298.1 K

T₂ = 55 + 273.1 = 328.1 K

To find:

V₂= ?

On substituting the values:

45/298.1 = V₂/328.1

V₂ = 52.8 L

Thus, the volume of the balloon is 52.8 liters.

H = 1 element

Cl = 1 element

For the products:

Ca = 1 element

Cl = 2 elements

H = 2 elements
