Answer: 373 mL

Explanation:

Since there is no change in pressure, the formula: V / T = V / T can be used.

However, you must first convert the temperatures to Kelvin by adding 273 to them:

(19 + 273) = 292K and (90 + 273) = 363K.

Now, plug in: V / 292 = 464 / 363 → V = 373 mL :)

"Which statement is true about the removal of a terminal phosphate" from ATP? Choose one: A. The reaction is associated with a p
Mamont248 [21]

Answer:

C. The reaction is energetically favorable.

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

ATP+H_2O\rightarrow ADP+P_i+\ energy

The Gibbs' free energy change of this reaction, \Delta G^0=-7.3\ kcal/mol

Hence, Option A is not correct.

It is a type of hydrolysis reaction in which water is being added to the molecule.

Hence, Option B is not correct.

The Gibbs' free energy change is negative which means that the reaction is energetically favorable.

Option C is correct.

What is an asteroid?
LUCKY_DIMON [66]
Asteroids are rocky space debris that are formed from interspacial collisions and collection of dusty particles. our solar system has an enormous asteroid belt between Mars and Jupiter.

Jupiter also has more local asteroids that are locked to its gravitational pull.

Not to be confused with a comet or meteor.

Interpret and describe an example of a chemical formula. Summarize the two parts a chemical formula must have.
k0ka [10]

Answer and Explanation:

A chemical formula is composed by chemical symbols (in letters, which indicate the chemical elements) and subscripts (numbers). For example, let see the chemical formula for <em>carbon dioxide</em>:

CO₂

The letters C and O are the chemical symbols for the elements carbon (C) and oxygen (O). The number 2 in subscript indicates that there are 2 atoms of O per molecule. The subscript 1 is generally not indicated in chemical formulae, so it is assumed that the number of atoms of C is 1.

Summarizing, the chemical formula CO₂ indicates us that the molecule if formed by 1 atom of the element carbon (C) and 2 atoms of the element oxygen (O).
