Data Given:
Pressure = P = ?
Volume = V = 3.0 L
Temperature = T = 115 °C + 273 = 388 K
Mass = m = 75.0 g
M.mass = M = 44 g/mol
Solution:
Let suppose the Gas is acting Ideally. Then According to Ideal Gas Equation,
P V = n R T
Solving for P,
P = n R T / V ------ (1)
Calculating Moles,
n = m / M
n = 75.0 g / 44 g.mol⁻¹
n = 1.704 mol
Putting Values in Eq. 1,
P = (1.704 mol × 0.08205 atm.L.mol⁻¹.K⁻¹ × 388 K) ÷ 3.0 L
P = 18.08 atm
Answer:
Partial positive on hydrogen and partial negative charge on oxygen atom
Explanation:
<span>The DNA or deoxyribonucleic acid is composed of a pentose sugar,
a base and phosphate group. The bases are adenine, thymine, cytosine and
guanine. Guanine always forms hydrogen bonds with cytosine. Remember the
statement “Apples in the Tree, Cars in the Garage”. The A stands for adenine
and pairs with T-thymine then C – cytosine and G – guanine. </span>
Copper sulphide has the formula CuS and copper sulphate is CuSO4
CuS is a compound of sulphur and copper only while CuSO4 has these 2 elements plus Oxygen
