The correct matches are as follows:
1. Big Bang theory: Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.
2. Steady state theory: Theory about the origin of the universe that suggest that the universe has and will continue to be at a steady continuous state.
3. Oscillatory universe theory: Theory about the origin of the universe that suggests the universe is a never ending cycle of expansion and contraction.
4. Nebular theory: Theory about the origin of the solar system that suggest our sun and planet formed from a cloud of dust and gas.
5. Inflation theory: Theory that upholds the big bang theory but suggest there was an extremely rapid expansion or inflation milliseconds after the big bang.
6. Condensation theory: Theory about the origin of the solar system that agree with the nebular theory but stresses the importance of interstellar dust in planet formation.
Did you get the answer bc it would rly help me out thanks
The % yield if 500 g of sulfur trioxide reacted with excess water to produce 575 g of sulfuric acid is calculated using the below formula
% yield = actual yield/ theoretical yield x100
actual yield =575 grams
to calculate theoretical yield
find the moles of SO3 used =mass/molar mass
= 500g/ 80 g/mol =6.25 moles
SO3+H2O=H2SO4
by use of mole ratio of SO3 : H2SO4 which is 1:1 the moles of H2SO4 is also= 6.25 moles
the theoretical yield of H2SO4 is therefore = moles /molar mass
= 6.25 x98= 612.5 grams
%yield is therefore= 575 g/612 g x100= 93.9 %

Explanation:
you can figure it out in one second
Answer:
he amount of heat gained by the water is 1.59 kJ
Explanation:
Relation between heat energy, specific heat and temperature change is as follows
Q = mCΔT
where, Q or q = heat energy
m = mass
C = specific heat =4.186J/g°C
ΔT = (28°C - 25°C) = 3°C
Now, putting the given values into the above formula as follows.
Q = mCΔT
= 127 × 4.186 × 3
= 1594.86 J or 1.59 kJ
Therefore, we can conclude that the amount of heat gained by the water is 1.59 kJ
