Answer:

R = 40 ohms

Explanation:

Two bulbs have a resistance of 20 ohms when working normally.

When they are placed in series, the combined resistance is given by :

R = R₁ + R₂

We have, R₁ = R₂ = 20 ohms

R = 20 +20

= 40 ohms

Hence, the combined resistance of the two bulbs is 40 ohms.

Answer:

26.74g

Explanation:

The equation of the reaction is;

SIO₂ + 3C --> SiC +2CO

From the balanced equation, the relationship between SiC and C is;

3 mol of C produces 1 mol of SiC

Converting mol to mass using; Mass = moles * Molar mass

Mass of SiC = 1 mol * 40.11 g/mol = 40.11g

This means;

3 mol of C produces 40.11g of SiC

2 mol of C produces xg of SiC

3 = 40.11

2 = x

x = 2 * 40.11 / 3 = 26.74g

Answer:

the answer would be 11 grams of water/sugar water

Explanation: its that because 11 grams plus 1 gram = 11 grams

even though it may seem it may just go away that mass has to go somewhere it just doesn't vanish from the earth.

Answer:

B and C look blue therefore they are hot but A and C look big

The appearance of the three stars is compared by their colors and sizes.

In the image you can see the stars of the constellation Orion.

According to the above, it can be inferred that the three stars differ in their colors and sizes. Their colors can be determined by the chemical composition of them, while their sizes by the distance that separates them from the Earth, making the farthest ones look smaller and the closest ones, bigger.

We know, molecular mass of sucrose is 342 g/mol.

So, number of moles in 18 g is :

[tex]n_1 = \dfrac{342\ g/mol}{18\ g}\\\\n_1 = 0.053 \ moles[/tex]

Also, number of moles of water is :

[tex]n_2 = \dfrac{180}{18} \\\\n_2 = 10 \ moles[/tex]

We know, 1 mole of sucrose contain 11 moles of oxygen.

So,

[tex]n' = 0.053\times 11\\\\n'= 0.583\ moles[/tex]

1 mole of water contain 1 mole of oxygen .

So, moles of oxygen in water are :

[tex]n'' = 10\ moles[/tex]

Total number of moles, [tex]n' + n'' = 10.583 \ moles[/tex] .

Number of oxygen atoms are :

[tex]N = 6.022 \times 10^{23}\times 10.583\\\\N = 6.37 \times 10^{24}[/tex]

Hence, this is the required solution.

Answer:

three chlorine atoms

Explanation:

The specific heat of the substance  : c = 1.044  J/g  °C J/g  °C

Given

Heat absorbed by substance = 989 J

m = mass = 37.9 g

Δt = Temperature difference : 25 °C

Required

The specific heat

Solution

Heat can be formulated

Q = m.c.Δt

Input the value :

989 = 37.9 x c x 25

c = 989 : (37.9 x 25)

c = 1.044  J/g  °C

Blue is the metal Metals react by losing electrons from the outermost shell, which means their outermost electrons and now closer to the nucleus (one shell lower) and thus they get smaller when you go from metal atom to metal ion.

Explanation:

Answer:

the molecules are tightly bound together, making it easy for electric currents to jump from one molecule to the next.

Explanation:

Answer:

Explanation:

At sunset the light from the sun grazes across the surface of the earth, passing through a long column or pathlength of atmosphere. During its passage through the atmosphere the blue components of the light are reduced in intensity, making the transmitted beam of sunlight more yellow or even red in color.

Small particles of dust and pollution in the air can contribute to (and sometimes even enhance) these colors, but the primary cause of a blue sky and orange/red sunsets or sunrises is scattering by the gas molecules that make up our atmosphere. ... In this way, clouds act as a screen on which nature's colors are painted.

Answer:

T₂  = 259.84 K

T₂  = -13.31 °C

Explanation:

Given data:

Initial pressure = 700 mmHg

Initial temperature = 30.0°C (30+273.15 K = 303.15 K)

Final temperature = ?

Final pressure = 600 mmHg

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

700 mmHg /303.15 K  = 600 mmHg / T₂

T₂  = 600 mmHg × 303.15 K / 700 mmHg

T₂  =181890 mmHg.K /700 mmHg

T₂  = 259.84 K

Temperature in celsius

259.84 K - 273.15 = -13.31 °C
