Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
=
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ =
Also;
V₂ =
So from the choices both are correct
Answer:The sun
Explanation:
Coal and crude oil are made from the remains of plants and animals that died long ago. The primary energy source in an ecosystem is the sun. Plants take in energy from the sun to produce high energy molecules which are transferred along the food chain to animals. When these plants and animals die, the high energy molecules are now stored in fossil fuels. Recall that the molecules were formed using energy from the sun, therefore, the sun is the energy source from which the high energy molecules contained in fossil fuels are obtained.

The human eye see objects through light reflects off
objects, enters the eyes, and is detected by the optic nerve in the retina. The
answer is letter B. The rest of the
choices do not answer the question above.
The moles of I2 that will form 38.58g of Ni3 is 0.147 moles
calculation
write the equation for reaction for formation of Ni3 from I2 and N2
that is 3I2 + N2 = 2NI3
find the moles of Ni3 formed = mass/molar mass
= 38.58g/ 394.71 g/mol = 0.098 moles
by use of mole ratio between I2 to NI3 which is 3 :2 the moles of I2
= 0.098 x3/2 = 0.147 moles
