What is a Fahrenheit??

the answer is B not A

let me explain why see a says water vapor in the air turns to liquid water in the form of rain see that is a physical change not a chemical change it is B because it is undergoing a chemical change by the uv rays for that reason it is not D because that is just releasing sulfur dioxide in the air that is not a chemical change nor a physical change so then i leaves us with C so C is wrong because it just being suspended in the air not physical or chemical change

can i also have brainlyest i never had it before

Answer: The star's outer layers drifts away.

Explanation: When a star starts running out of fuel the pressure in the core becomes very high which pushes the outer layers of the star.

A sun like star becomes a red giant and after throwing away the mass, the core contracts to becomes a white dwarf.

A massive star becomes super-giant and then the core becomes a neutron star or a black-hole.

Answer:

The answer is d

Explanation:

Answer:

• 17.6 g of chlorine gas reacted.

Explanation:

1) Chemical equation:

• 2Na + Cl₂ (g) → 2NaCl (s)

2) Mole ratios:

• 2 mol Na : 1 mol Cl₂ : 2 mol NaCl

3) Number of moles of sodium chloride (NaCl) measured (produced):

• Number of moles = mass in grams / molar mass

• Molar mass of NaCl = 58.44 g/mol

• Number of moles of NaCl = 29.0 g / 58.44 g/mol = 0.496 mol

4) Number of moles of chlorine gas (Cl₂) reacted:

• From the stoichiometric mole ratios:

       1 mol Cl₂ / 2 mol NaCl = x / 0.496 mol NaCl

       x = 0.496 mol NaCl / 1 mol Cl₂ / 2 mol NaCl = 0.248 mol Cl₂.

5) Convert 0.248 mol Cl₂ into mass in grams:

• mass in grams = molar mass × number of moles

• molar mass of Cl₂ = 70.9 g/mol

• mass in grams = 70.9 g/mol × 0.248 mol = 17.6 g ← answer
