How does the heat content of the reaction change in the process of photosynthesis when a glucose molecule is formed?
patriot [66]

In the process of photosynthesis, when a glucose molecule is formed, THE HEAT CONTENT OF THE REACTION INCREASES, THUS, THE VALUE OF Q IS POSITIVE.

There are two types of chemical reaction, these are exothermic and endothermic reaction. Exothermic reactions are those reactions that gives off heat when they are occurring while endothermic reactions are those reactions that absorb heat from their environment during the course of reaction. Photosynthesis is an endothermic reactions; it absorbs energy from the environment when it is occurring, thus, the heat content of the product is always more than that of the reactants. The heat content of compounds are represented by letter q. For photosynthesis, q is positive, because there is an increase in the heat content of the product [glucose] formed.

The distance from the Moon to Earth is 5.46 * 108 km. How long does it take a laser need to travel between the moon and earth?
Gennadij [26K]

Answer:

B. 1.82(10³) seconds (1820 seconds)

Explanation:

Speed of Light: 3.00(10⁸) m/s or 3.00(10⁵) km/s

We know the distance from the Moon to Earth as 5.46(10⁸) km

We simply divide the distance by the speed of light:

\frac{5.46(10^8)}{3.00(10^5)}

We should get 1820 seconds or B. 1.82(10³) as our answer.

A glass container was initially charged with 1.95 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as
rjkz [21]

Answer:

45830.4 moles

Explanation:

Ideal gas law is the hypothetical equation in which the pressure, volume, and temperature of the gas are directly related. It can be denoted as:

PV = nRT

The ideal gas law is:

PV = nRT

where,

P = Pressure

V = Volume

R = Gas constant

T =Temperature

n = moles

Given:

Moles in container = 1.95

Temperture = 294.85 K

Pressure = 3.75 atm

Volume =?

Substituting the values:

V = nRT/P

V = 1.95 × 0.082 × 294 / 3.75

Volume = 12.5 L

Now, the condition when changed, such that temperature is 301.25 K, pressure is 0.998 atm, and Volume is 12.5 L, then moles will be equal to:

PV/RT = n

0.998 × 12.5 / 0.082 × 301.25 = n

n = 45830.4 moles

Therefore, 0.521 moles is still present in the container.
