Answer:

The correct option is: c. Mercury is closer to the Sun                                

Explanation:

Mercury is the first and the smallest planet of the Solar system that is present <u>closest to the Sun</u>. The surface temperature of this planet ranges from -173 °C-427 °C or 100-700 K.

Due to the small size and high surface temperature of the planet, the gravity can not retain a significant atmosphere.

Whereas, Moon is the only permanent <u>natural satellite of the planet Earth.</u> It is the second most brightest object in the Earth's sky after Sun.

<u>Since Mercury is much closer to the Sun than the Moon. Therefore, Mercury is much hotter than the Moon.</u>

Viktor [21]

Answer:

0.70 J/g.°C

Explanation:

Step 1: Given data

  • Mass of graphite (m): 402 g
  • Heat absorbed (Q): 1136 J
  • Initial temperature: 26°C
  • Final temperature: 30 °C
  • Specific heat of graphite (c): ?

Step 2: Calculate the specific heat of graphite

We will use the following expression.

Q = c × m × ΔT

c = Q / m × ΔT

c = 1136 J / 402 g × (30°C - 26°C)

c = 0.70 J/g.°C

murzikaleks [220]

The given question is incomplete. The image present in the question for Reaction A is attached below along with the answer.

Explanation:

Pyruvate molecule reacts with Coenzyme A in the presence of oxygen and it results in the formation of acetyl Coenzyme A and carbon dioxide.

The enzyme pyruvae dehydrogenase helps in catalyzing this reaction. As in this biochemical reaction NAD^{+} gets converted into NADH.

This reaction is shown in the image attached below.

A sample of helium gas has a pressure of 1.20 atm at 22°c. at what celsius temperature will the helium reach a pressure of 2.00
sukhopar [10]
Gay-Lussac's law gives the relationship between pressure and temperature of a gas.
it states that for a fixed amount of gas of constant volume pressure is directly proportional to temperature. 
P/T = k
where P - pressure, T - temperature and k - constant 
\frac{P1}{T1} =  \frac{P2}{T2}
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
temperature should be in the kelvin scale,
T1 = 22 °C + 273 = 295 K
substituting the values in the equation 
\frac{1.20atm}{295 K}  =  \frac{2.00 atm}{T}
T = 492 K
new temperature - 492 - 273 = 219 °C
