Answer:
Molarity NaOH = 0.85M (2 sig figs)
Explanation:
48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O
2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH
2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH
Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)
Answer:
if I'm not mistaken, it is a mixture
<u>Answer:</u> The temperature of the ideal gas is 
<u>Explanation:</u>
To calculate the temperature, we use the equation given by ideal gas equation:

where,
P = Pressure of the gas = 142,868 Pa = 142.868 kPa (Conversion factor: 1 kPa = 1000 Pa)
V = Volume of gas = 1.0000 L
n = number of moles of ideal gas = 0.0625 moles
R = Gas constant = 
T = temperature of the gas = ?
Putting values in above equation, we get:

Hence, the temperature of the ideal gas is 
Answer:
Chemical energy
Explanation:
Energy in carbohydrates is stored as chemical energy which is released when the carbohydrate is broken down by the body to give glucose and ATP. Animals eat carbohydrates as energy molecules from which they derive energy from the stored chemical energy.
