[tex]\% Co=10.7\%[/tex]

Explanation:

Hello!

In this case, since this is a mixture composed by cobalt and waste rock, we can compute the percent by mass of cobalt as shown below:

[tex]\% Co=\frac{m_{Co}}{m_{Co}+m_{waste}} *100\%\\\\[/tex]

Thus, we plug in to obtain:

[tex]\% Co=\frac{10.500000g}{10.500000g+87.3} *100\%\\\\\% Co=10.7\%[/tex]

Answer:

1.29×10²⁴ atoms are in 2.15 moles of water. Atom is also the smallest piece of substance with chemical element-like characteristics.

The smallest unit of matter that may be divided without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. As a result, the atom serves as the fundamental unit of chemistry.

Space makes up the majority of an atom. The rest is made up of a cloud of electrons that are negatively charged surrounding a nucleus that is positively charged made up of protons and neutrons. The behaviour of the electron in an atom can be compared to that of particles surrounding the nucleus.

number of atoms = number of moles ×6.022×10²³

                               = 2.15×6.022×10²³

                                = 1.29×10²⁴

Therefore, 1.29×10²⁴ atoms are in 2.15 moles of water.

Answer:

y

Explanation:

Answer:

B) A gas is produced

Explanation:

These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.

Examples:

Combustion

Neutralisation between acids and alkali

These are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.

Step 2: Calculate the final volume of the balloon

The balloon is filled with air. If we assume it behaves as an ideal gas, we can calculate the final volume of the balloon using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 0.5 L × 20 K/293 K = 0.03 L

The number of atoms of any element in the given chemical formula is the number that is written on the foot of the symbol of that element. Therefore, chlorine has the strongest attraction for electrons in a chemical bond.

Atom is the smallest particle of any matter. Atom combines to form element and element combine to form molecule or compound.

Atom consists of electron, proton and neutron. The total mass of atom is inside the nucleus. Inside the nucleus proton and neutron is there. So calculate mass of an atom, total mass of all protons is added to the total mass of neutron. Electrons revolve around the nucleus.

Electronegative element have greatest strongest attraction for electrons due to high effective nuclear charge. Among the given molecules, chlorine is the most electronegative element. Chlorine has the strongest attraction for electrons in a chemical bond.

Therefore, chlorine has the strongest attraction for electrons in a chemical bond.

Answer:

cohesion and adhesion

Answer:

Cohesion, Adhesion, Relatively high boiling point, and high surface tension.

Explanation:

Cohesion and adhesion give water molecules their 'stickiness' for each other and other molecules/surfaces, and high surface tension is why things like feathers can 'float' on the surface of water.

Answer:

0.370 M

Explanation:

Step 1: Given data

Molar concentration of the sodium carbonate solution: 0.185 M

Step 2: Write the balanced dissociation equation

Sodium carbonate is a strong electrolyte that dissociates according to the following equation.

Na₂CO₃(aq) ⇒ 2 Na⁺(aq) + CO₃²⁻(aq)

Step 3: Calculate the molar concentration of sodium ions

The molar ratio of Na₂CO₃ to Na⁺ is 1:2.

0.185 mol Na₂CO₃/L × 2 mol Na⁺/1 mol Na₂CO₃ = 0.370 mol Na⁺/L
