What would increase the mass of the Helium atom, without changing its identity?

1 answer:

7 0

A because protons make the atom the element it is and the molar mass is made up by the neutrons and protons. The protons must stay the same to keep the same element and electrons hardly have mass so A

A cell is placed into a solution that has the same osmolarity. however, one of the solutes in the solution is able to move acros

Marizza181 [45]

Hi friend,

the answer is HYPOTONIC

The as the solvent from the cell will move from hypotonic solution(inside) to hypertonic solution(outside).
AT equilibrium the outside will be hypotonic

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of

Elodia [21]

Answer:

$\boxed {\boxed {\sf 121.905 \ J }}$

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

$q= mc \Delta T$

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

ΔT= final temperature - initial temperature
ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

$m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C$

Substitue the values into the formula.

$q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)$

Multiply the first numbers together. The grams will cancel.

$q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)$

Multiply again, this time the degrees Celsius cancels.

$q= 121.905 \ J$

<u>121.905 Joules</u> are required.

Answer:

Explanation:

Photosynthesis produces carbon dioxide (chemical gas) which is used in cellular respiration to make oxygen. That oxygen is then used in photosynthesis to make more carbon dioxide and so on.
