Balance this reaction:
(_)NH3 + (_)H2SO4 = (_) (NH4)2SO4
1.2.2
2,1,1
2.2.1​

Answer:

24.06 g of CO₂

Explanation:

The balanced equation for the reaction is given below:

CH₄ + 2O₂ —> 2H₂O + CO₂

Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 2 × 32 = 64 g

Molar mass of CO₂ = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.

Thus, 24.06 g of CO₂ were produced from the reaction.

Answer:

25000 is the answer

Explanation:

The answer is 25000 hope this helps you

25,000N is the total force, the train's engine need to create so the train is going uphill at a constant speed.

A force in physics is an effect that changes the velocity of a mass-moving object, causing it to accelerate from rest, for example. It is a vector quantity since it can be a push or perhaps a pull and always has magnitude and direction. It is denoted by the letter F and is measured in newtons (N), the SI unit of force (formerly P).

The net force exerted on an object approximately equal to the rate where its momentum varies over time, according to the original formulation of Newton's second law.

The force by the train weight Fw= 150,000N

The force creates by the friction Ff=25,000N

total force =Fw + Ff

                = 150,000N+25,000N

                = 25,000N

Therefore, 25,000N is the total force.

they are becoming negatively charged.

Answer:

3

Explanation:

The atomic mass is equal to the number of protons in an atom (and electrons if the atom is neutral).

Answer:

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Answer:

The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.

C. Atoms of chlorine (CI)

A covalent bond is created when the electrons from the two involved atoms are shared equally.The pair of electrons involved in this kind of bonding is referred to as the shared pair or bonding pair. Here the atoms of chlorine have non-polar covalent bonds. The correct option is C.

A non-polar covalent connection is created when atoms with an equal amount of electrons share one another. The electronegativity of the two atoms is equivalent. When two atoms with similar electron affinities join together, like in the case of diatomic elements, it happens.

Non-polar covalent compounds are those in which there is no variation in electronegativity. In these compounds, the electronegativity does not change, preventing the motion of the bond pair's electrons in the direction of the linked atoms.

As a result, a molecule is non-polar and non-conducting since there is no bond or dipole moment between its atoms and no buildup of charges on the atoms.

Thus the correct option is C.

Explanation:

This is because the chlorine reacts with the sodium bromide, forcing it to go brown.

I hope this helps, good luck! (✿◡‿◡)

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.

In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.

Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

Answer:

Explanation:

Thus, if we have 6.022 × 10 23 O atoms, we say we have 1 mol of O atoms. If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules.

For example the atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore the molar mass of methane is 16g. We say that one mole of methane has a mass of 16 g, and that there are 6.022 x 1023 atoms in that mass of methane.

The number of atoms present in 0.75 mole of methane, CH₄ is 4.515×10²³ atoms

1 mole of CH₄ = 6.02×10²³ atoms

From Avogadro's hypothesis, we discovered that:

1 mole of CH₄ = 6.02×10²³ atoms

Therefore,

0.75 mole of CH₄ = 0.75 × 6.02×10²³

0.75 mole of CH₄ = 4.515×10²³ atoms

Thus, 4.515×10²³ atoms are present in 0.75 mole of CH₄
