Answer:
physical changes
Explanation:
mixtures are the combination of two or more components through physical means and can be broken down or reversed into its initial state
Answer:
0.4 moles of water produced by 6.25 g of oxygen.
Explanation:
Given data:
Mass of oxygen = 6.25 g
Moles of water produced = ?
Solution:
Chemical equation;
2H₂ + O₂ → 2H₂O
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 6.35 g/ 32 g/mol
Number of moles = 0.2 mol
Now we will compare the moles of oxygen with water:
O₂ : H₂O
1 : 2
0.2 : 2×0.2 = 0.4 mol
0.4 moles of water produced by 6.25 g of oxygen.
Answer: 1
Explanation: From point A the fire is making "A" hot so pint B will get hot I think..... correct me if I'm wrong but I had this before and got an A so I hope it helps you out a lil bit. (Brainiest??)
ROY G BIV is associated with this type of electromagnetic radiation <span>B. visible light.
</span>ROY G BIV - red , orange, yellow, green, blue, indigo, violet.
First find the molar mass of C6H12O6 to convert from grams to moles. Divide grams by the molar mass to get moles.
molar mass = 6(12.01) + 12(1.008) + 6(16) = 180.156 g/mol
0.017 g / 180.156 g/mol = 0.000094 mol C6H12O6
Molarity = mol/L
You’re solving for Liters of solvent.
L = mol/Molarity
mol = 0.000094
Molarity = 2.00
L = 0.000094/2.00 = 0.000047 L = 0.047 mL
