Answer:
3H2SO4 + 2B(OH)3 -> B2(SO4)3 + 6H2O
Explanation:
Answer: 149
Explanation:
Using the ideal gas equation; PV = nRT
P= Pressure = 0.910 atm, T= Temperature = ?
V= Volume = 4.0L R = Gas constant = 0.08206 L.atm/mol/K
n = number of moles = 0.297
Making 'T' the subject of the formular, we have;
T = P V/ n R = 0.910 x 4 / 0.297 x 0.08206
= 149
Answer:
an exothermic reaction that Increase in entropy
B)
CH₄ + 2O₂ ---> CO₂ + 2H₂O
Answer:
Explanation:
The values are given in scientific notation.
Scientific notation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
. The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³
Ordinary notation:
The ordinary notation is expended notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.
a) 7.356 ×10⁻⁶ km
0.000007356 km
b) 3.02 ×10⁻⁵ g
0.0000302 g
c) 8.348 ×10⁶ Kg
8,348,000 kg
d) 7.6352 ×10⁻³ s
0.0076352 s
