The volume did not change, it remained at 20 ml

Given

20 ml a sample gas at STP(273 K, 1 atm)

T₂=546 K

P₂=2 atm

Required

The volume

Solution

Combined gas Law :

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

Input the value :

[tex]\tt \dfrac{1\times 20}{273}=\dfrac{2\times V_2}{546}\\\\V_2=\dfrac{1\times 20\times 546}{273\times 2}\\\\V_2=20~ml[/tex]

The volume does not change because the pressure and temperature are increased by the same ratio as the initial conditions (to 2x)

An earthworm has a closed circulatory system.

The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.

As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.

They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.

Answer:

Ans => C => 43.3%

Explanation:

2CO + O₂ => 2CO₂

Given     1g CO = 1g/28g·mol⁻¹ = 0.036 mol CO

b/c coefficient of CO = coefficient of CO₂ => moles CO₂ = 0.036 mol = 0.036mol x 44g/mol = 1.57 gCO₂ (theoretical yield)

%Yield = (actual yield/theoretical yield) x 100% = (0.68g/1.57g) x 100% = 43.3%

Explanation:

If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.

Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.

Answer:

The reaction is exothermic.

I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.

Answer:

36 oxygen atoms

Explanation:

From the question given above, the following data were obtained:

Compound => 4Al₂(CO₃)₃

Number of Oxygen atom in the compound =?

The number of oxygen atom in the above compound can be obtained as follow:

4Al₂(CO₃)₃

Al = 4 × 2 = 8 atoms

C = 4 × 3 × 1 = 12 atoms

O = 4 × 3 × 3 = 36 atoms

From the simple illustration made above, there are 36 oxygen atoms in the compound.

Answer:

5446.8 J

Explanation:

From the question given above, the following data were obtained:

Mass (M) = 50 g

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Specific heat capacity (C) = 0.89 J/gºC

Heat (Q) required =?

Next, we shall determine the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 192.4 – 70

ΔT = 122.4 °C

Finally, we shall determine the heat required to heat up the block of aluminum as follow:

Mass (M) = 50 g

Specific heat capacity (C) = 0.89 J/gºC

Change in temperature (ΔT) = 122.4 °C

Heat (Q) required =?

Q = MCΔT

Q = 50 × 0.89 × 122.4

Q = 5446.8 J

Thus, the heat required to heat up the block of aluminum is 5446.8 J

Explanation:

Among the halogens given in this problem, iodine has the lowest attraction for electrons.

This property is known as electronegativity.

Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.

Answer:

All of them have a nucleus..

Explanation:

Pretty simple stuff.  There's no cell without one.

Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.

Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.

The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.

Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).

Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

amount of He = (7.91 × 10^22) ÷ (6.02 × 10^23) = 0.131mol (3sf)

Explanation:

you make use of the mole concept formula

Answer:

well, chlorine will undergo in a chemical reaction

Explanation:

neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.

whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence

it will take place in a chemical reaction

Answer:

Explanation:

Brooke should turn so that her back is to the Sun to her wall, and hold the Moon (ball representing Moon) in front of her. Therefore, option (D) is correct.

The eclipse of the moon occurs when the earth comes in between the sun and the moon. The earth blocks the light coming from the sun from reaching the surface of the moon and casts its shadow on the moon.

A lunar eclipse occurs on a full moon day and can be observed up to 3 lunar eclipses per year.  A lunar eclipse can be categorized depending on how the sun, the moon, and the earth line up.

A partial lunar eclipse is when only a part of the moon moves into the shadow's earth. A total lunar eclipse is when the earth crossed directly in front of the moon and casts its shadow.

If Brooke's head is earth then it will be in the center and her back will be towards to sun poster on the wall. So that the ball in her hand can play as a moon to show the lunar eclipse.
