How does thermal energy flow?

Answer:

0.5474

Explanation:

3.22 x 0.17

     \/

322 x 17 = 5,474

[] There are four places "after" the decimal in 3.22 and 0.17 combined, meaning we move the decimal to the right four times in our current answer

-> 5,474 becomes 0.5474

Have a nice day!

Answer:0.55

Explanation:

3.22 × 0.17 calculated with significant figures is 0.55, which has 2 sig figs and 2 decimals. There are 2 steps to calculate 3.22 × 0.17 with sig figs. 0.55 rounded to 1 sig figs is 0.6.

Explanation:

P1. V1/T1 = P2. V2/T2

Apply this

since here, P1 = P2

100 ml / 300 = V2/ 200

==> 100*200/300 = V2

===> V2 = 66.66 ml

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.

Answer:

No, ionic compounds are crystals of infinite cations and anions bound together. There is no “molecule” of ionic compounds such as, for example, NaCl, because there are no single units of the compound.

Explanation:

Ionic compounds are not considered to be molecules because they do not consist of discrete, covalently bonded units like molecules.

In ionic compounds, the bonding occurs through the transfer of electrons from one atom to another, resulting in the formation of ions. These ions are held together by strong electrostatic attractions, known as ionic bonds.

Unlike molecules, which are formed by the sharing of electrons in covalent bonds, ionic compounds do not have individual units with fixed numbers of atoms. Instead, they exist as a three-dimensional lattice structure composed of alternating positive and negative ions. The ions are arranged in a repeating pattern throughout the crystal lattice.

yes agree. I is describing a feeling/ reaction to an action I hope this helps!:)

Answer: In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Answer:

Bubbling and fizzing are likely to occur when a new substance is formed. The other examples are simply changing to a different form of the same substance.

A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.

Explanation:

Good Luck!

Answer: 23.48 g

Explanation:

formula: mass = density x volume

Volume of copper = 2.62 cm^3

Density of copper = 8.96 g/cm^3

mass = 8.96 x 2.62 = 23.4752

I think you may have chosen the wrong subject for your question, besides where is the context to this?

A 1.00 mole of Sulfuric acid (H₂SO₄) contains the largest number of atoms (7 atoms/molecule). Option B is correct.

To determine which of the given compounds contains the largest number of atoms in 1.00 mole, we need to consider the number of atoms in each compound.

1.00 mole of NH₃ contains:

1 mole of N atoms (1 atom/molecule)

3 moles of H atoms (3 atoms/molecule)

Total atoms = 1 + 3 = 4 atoms/molecule

1.00 mole of H₂SO₄ contains:

2 moles of H atoms (2 atoms/molecule)

1 mole of S atoms (1 atom/molecule)

4 moles of O atoms (4 atoms/molecule)

Total atoms = 2 + 1 + 4 = 7 atoms/molecule

1.00 mole of HBr contains:

1 mole of H atoms (1 atom/molecule)

1 mole of Br atoms (1 atom/molecule)

Total atoms = 1 + 1 = 2 atoms/molecule

Therefore, 1.00 mole of H₂SO₄, contains the largest number of atoms.

Hence, B. is the correct option.

The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

The weight of an object is determined as the product of the object's mass and acceleration due to gravity.

F = mg

The gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.

[tex]F = \frac{GmM}{R^2} [/tex]

[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]

where;

M is the mass of the earth

R is the radius of the earth

Thus, the relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].
