hydrogen?
2 H2 + O2 → 2 H2O

Answers

Answer:

12g

Explanation:

The following equation is given in this question:

2H2 + O2 → 2H2O

According to this balanced chemical equation, 2 moles of hydrogen gas is used to produce 2 moles of water molecule.

Hence, if 12 grams of hydrogen is used, 12 × 2/2 = 24/2

= 12 grams of H2O will be produced.

Below is a picture of two blocks made of different materials. Block A Block B grams grams If Block A is located on the Moon and Block B is located on Earth, which of the following is true about the two blocks?
a: they have the same density.
b: they have the same volume.
c: they have the same mass.
d: they have the same weight. ​

Answers

Answer:

A

Explanation:

this is because density is the mass per unit volume of an object

If Block A is located on the Moon and Block B is located on Earth, then the truth about the two blocks will be they have the same mass, and they have the same density. The correct option is a and c.

What is mass?

Mass is a physical body's total amount of matter. By multiplying the object's volume and density, it can be determined.

Density, volume, mass, and weight are the four entities that are supplied. The volume and weight of the object on the moon will alter as a result of these entities. They will be different in the universe if he goes to Earth.

The location and gravitational field of an object do not affect its density or mass.

Thus, the correct options are a: they have the same density, and c. they have the same mass.

On the set of a movie, dry ice (solid carbon dioxide) is used to make the appearance of fog. After the dry ice is taken out of cold storage, it is placed on the ground. As dry ice warms, it converts from a solid directly to a gas. Gaseous carbon dioxide has a density greater than air, thus allowing it to move across the ground as if it were fog. Which statement best describes this process

Answers

Answer:

- The dry ice is cooling the ground it rests upon as heat is transferred from the ground to the dry ice.

Explanation:

The above statement correctly elaborates the process of using dry ice to develop the appearance of fog. When the dry ice is placed on the ground, the heat of the ground is transferred to the dry ice. This will result in the increase in the kinetic energy of the CO2 molecules. Thus, the solid will directly convert into gas and it will lead to the formation of gas in the air. Since CO2 possesses a higher density, it will look like fog and thus, giving the perfect shot for the fog scene.

Hiii pls help me to write out the ionic equation ​

STEP I

This is the balanced equation for the given reaction:-

[tex] 2KOH_{(aq)} + H_2SO_4{}_{(aq)} \rightarrow K_2SO_4{}_{(aq)} + 2H_2O_{(l)} [/tex]

STEP II

The compounds marked with (aq) are soluble ionic compounds. They must be

broken into their respective ions.

see, in the equation KOH, H2SO4, and K2SO4 are marked with (aq).

On breaking them into their respective ions :-

2KOH -> 2K+ + 2OH-H2SO4 -> 2H+ + (SO4)2-K2SO4 -> 2K+ + (SO4)2-

STEP III

Rewriting these in the form of equation

[tex] \underline{\pmb{2K^+} }+ 2OH^- + 2H^+ + \pmb{\underline{{SO_4{}^{2-}}} \: \rightarrow \: \underline{\pmb{2K^+}}} + \underline{\pmb{SO_4{}^{2-}}} + 2H_2O [/tex]

STEP IV

Canceling spectator ions, the ions that appear the same on either side of the equation

(note: in the above step the ions in bold have gotten canceled.)

[tex] \boxed{ \mathfrak{ \red{ 2OH^-{}_{(aq)} + 2H^+{(aq.)} \rightarrow H_2O{}_{(l)}}}} [/tex]

Answers

Answer:

Fe + CuO ----> FeO+ Cu

Explanation:

A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.

Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.

The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.

Calcium sulfate is a white solid found as two hydrates, a hemihydrate known as plaster of Paris and a dehydrate known as gypsum. The hemihydrate is a white solid. Given that the molar mass of the anhydrous calcium sulfate is 136.14 g/mol, the molar mass of the hemihydrate is 145.15 g/mol, and the molar mass of water is 18.015 g/mol, which formula gives the correct ratio for the hemihydrate

Answers

Answer:

2(CaSO4)*H2O

Explanation:

To solve this question we need to find the moles water, H2O, of calcium sulfate, CaSO4 as follows:

The molar mass of the anhydrous CaSO4 are 136.14g/mol and the molar mass of the hemihydrate is 145.15g/mol. The differences in molar mass represents the additional mass that water is producing:

145.15g/mol - 136.14g/mol = 9.01g/mol

A 1 mole of water weighs 18.015g/mol, the additional mass of water is due the addition of 1/2 moles of H2O. That means we have 1 mole of CaSO4 per 1/2 mole of H2O. That is the same:

2(CaSO4)*H2O

And this is the formula that gives the correct ratio for the hemihydrate.

B. Internal organ filled with liquid
c. Holds urine until it can be released into the environment
D. Internal organ filled with air sacs​

Answers

A: Swim bladder, also called air bladder, buoyancy organ possessed by most bony fish. The swim bladder is located in the body cavity and is derived from an outpocketing of the digestive tube. It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking. It also serves as a resonating chamber to produce or receive sound. In some species the swim bladder contains oil instead of gas. In certain primitive fish it functions as a lung or respiratory aid instead of a hydrostatic organ. The swim bladder is missing in some bottom-dwelling and deep-sea bony fish (teleosts) and in all cartilaginous fish (sharks, skates, and rays).

Explanation:

Calculate the volume (in L) that 3.25 mol of helium gas will occupy at a temperature of 25.0 °C and a pressure of 799 mm Hg.

Answers

Answer:

V = 6.34 L

Explanation:

Given that,

Number of moles of Helium gas, n = 3.25 mol

Temperature, T = 25 °C = 298 K

Pressure, P = 799 mm Hg

We know that,

PV = nRT

Where

R is the gas constant, R = 62.4 L-mm Hg/mol K

So,

[tex]V=\dfrac{nRT}{P}\\\\V=\dfrac{3.25\times 62.4\times 25}{799}\\\\V=6.34\ L[/tex]

So, the volume of the gas is 6.34 L.

What volume (in L) will a 32 g sample of butane gas, C4H10(9), occupy at a temperature of 45.0 °C and a pressure of 728
mm Hg?

Answers

Answer:

The volume of the gas is 0.015 m^3.

Explanation:

mass, m = 32 g

Temperature, T = 45 °C = 45 + 273 = 318 K

Pressure, P = 728 mm of hg = 0.728 x 13.6 x 1000 x 9.8 = 97027.84 Pa

Atomic mass = 4 x 12 + 10 x 1 = 58 g

Use the ideal gas equation

Let the volume is V.

P V = n R T

[tex]97027.8 \times V = \frac{32}{58}\times 8.31 \times 318 \\\\V = 0.015 m^3[/tex]  

Explanation:

The volume of the gas occupied can be calculated by using the ideal gas equation:

[tex]PV=nRT[/tex]

where,

P=pressure of the gas in atm

V=volume of the gas in L.

n=number of moles of the gas

R=0.0821L.atm.mol-1.K-1

T=absolute temperature

To get the volume of the gas, follow the below steps:

1) Calculate the number of moles of gas:

Number of moles of butane=mass of butane given/its molecular mass

[tex]=32g/58.0g/mol\\=0.55mol[/tex]

2) Convert temperature into kelvin scale:

T=(45+273)K=318K

3)Convert pressure into atm:

760 mm Hg =1 atm

then,

728 mm Hg=

728 mm Hg x 1 atm /760 mm Hg

=0.957 atm

Substitute all these values in the ideal gas equation to get the volume:

[tex]V=\frac{nRT}{P} \\V=0.55mol x 0.0821 L.atm.mol-1.K-1 x 318K / 0.957 atm\\V=15.0L[/tex]
