Answer:

The molar mass of sodium is 22.990 g/mol.

The molar mass of chlorine is 35.45 g/mol.

To calculate the molar mass of NaCl, we need to multiply the subscript of each element times its molar mass, then add them together. In this case since there is no subscript, it is understood to be

( 1 × 22.990 g/mol ) + ( 1×35.45 g/mol ) = ?

22.990 g/mol + 35.45 g/mol = ?

58.44 g/mol = ?

Answer:

A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products. Double replacement reactions are also called double replacement reactions, double displacement reactions, or metathesis reactions.

its called vapor. It can hold so much than colder eater based on the weather. For example if its cold it can heat up faster but if its hot it will maybe stay the same

Answer:

Option #2 (Green seeds)

Explanation:

Since both the plants are true-breeding, both plants only have the green allele. Therefore, their offspring must also only have the green allele and will therefore have green seeds.

Answer:

The heat energy released from the reaction is approximately 51.4791 kJ

Explanation:

The given parameters are;

The heat of the reaction of 2Cl (g) → Cl₂ (g) = -243.4 J

The given mass of Cl being converted to chlorine gas, Cl₂ = 15.0 g

From the reaction for the heat of formation, we have;

2 moles of chlorine produces 1 mole of Cl₂ to release 243.4 kJ of energy per mole of Cl₂

The mass of 1 mole of Cl ≈ 35.453 g

Therefore, from number of moles, n = Mass/(Molar Mass), we have;

The number of moles of chlorine, in 15.0 g of chlorine = 15.0/35.453 ≈ 0.423 moles

Therefore, given that 2 moles of Cl produces 1 mole of Cl₂, we have;

0.423 moles of Cl will produce 0.423/2 ≈ 0.2115 moles of Cl₂

The heat energy released from the reaction is therefore, H ≈ 0.2115 × 243.4 kJ = 51.4791 kJ.

Answer:

it forms copper hydroxide crystals

Explanation:

NaOH(aq)+CuSO4(aq)=Cu(OH)2(s)+Na2SO(aq)

Answer:

H2SO4

Explanation:

Firstly,

2.056% hydrogen = 2.056g of H

32.69% Sulphur = 32.69g of S

65.26% oxygen = 65.26g of O

Next, we convert each mass into moles by dividing by their respective molar mass:

H = 1, S = 32, O = 16

H = 2.056/1 = 2.056mol

S = 32.69/32 = 1.021mol

O = 65.26/16 = 4.078mol

Next, we divide each mole value by the smallest mole value (1.021)

H = 2.056/1.021 = 2.01

S = 1.021/1.021 = 1

O = 4.078/1.021 = 3.99

Approximately the ratio of H to S to O is 2:1:4, hence, the empirical formula for H, S and O is H2SO4.

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms present in a compound

The correct answer of the following is [tex]H_2SO_4[/tex]

The data is given as follows:-

We have to find the moles in the reaction.

The mas of the element is as follows:-

After solving the equation we get

[tex]H = \frac{2.056}{1} = 2.056mol\\\\S = \frac{32.69}{32} = 1.021mol\\\\O = \frac{65.26}{16} = 4.078mol[/tex]

Next, we divide each mole value by the smallest mole value (1.021)

[tex]H = \frac{2.056}{1.021} = 2.01\\\\S = \frac{1.021}{1.021} = 1\\\\O = \frac{4.078}{1.021} = 3.99[/tex]

The ratio of H to S to O is 2:1:4,

Hence, the empirical formula for H, S, and O is [tex]H_2SO_4.[/tex]

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)

Answer:

Density

Explanation:

Density is a measure of how much mass is contained in a given volume

Answer: The molecular formula will be [tex]C_6O_3H_{12}[/tex]

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

Empirical weight of [tex]C_2OH_{4}[/tex] is [tex]12\times 2+16\times 1+1\times 4=44g[/tex]

Molecular mass of compound is = 132 g

Answer:

A. stratosphere

E. Fertilizer

Explanation:

Answer:

1)They have different densities.

2) The molecules are packed differently

Explanation:

Oil and Water have different densities The first reason that water and oil don’t mix is because their molecules are packed differently. The molecules of water are packed very densely. (Would be good to show water molecules packed densely) In one glass of water, there are more molecules than the number of known stars in the universe!

Answer:

diff densities

Explanation:

Explanation:

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.

Answer:

Their average kinetic energy increases

Explanation:

The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.

Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.

Answer:

C. gold atoms

Explanation:

Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.

Metallic bonds join atoms of metals and alloys together.

The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.

The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.
