We view a year as the time it takes our planet to make one full orbit around the sun which is 365 days. The heliocentric theory is the sun-centered universe theory which has been proven and we currently use to this day. I'm not sure if you meant the geocentric theory with the Earth at the center of the universe instead.

An unknown compound contains 75.69% carbon, 8.80% hydrogen, and 15.51% oxygen by mass. A mass spectrometry analysis reveals that
tiny-mole [99]

Answer:

Molecular formula is C₂₆H₃₆O₄

Explanation:

The compound is 75.69 % C, 8.80 % H and 15.51 % O. This data means, that in 100 g of compound we have 75.69 g, 15.51 g and 8.80 g of, C, O and H, respectively. We know the molar mass of the compound, so we can work to solve the moles of each element.

In 100 g of compound we have 75.69 g C, 15.51 g O and 8.80 g H

In 412 g of compound we would have:

(412 . 75.69) / 100 = 311.8 of C

(412 . 15.51) / 100 = 63.9 g of O

(412 . 8.80) / 100 = 36.2 g of H

Now, we can determine the moles of each, that are contained in 1 mol of compound.

312 g / 12 g/mol 26 C

64 g / 16 g/mol = 4 O

36 g / 1 g/mol = 36 H

Molecular formula is C₂₆H₃₆O₄

if you want to see how the water molecules are split inside the thylakoid space, how many membranes would you have to cross to g
Feliz [49]

Answer:

4 biological membranes.

Explanation:

So in total, your water molecule has to go through your cell membrane, reach the outer membrane of your chloroplast and then through the inner membrane, and then lastly, it has to go through your thylakoid membrane to reach its final destination of the illumine. So in total 4 biological membranes.

An aircraft is taking a group of skydivers up into the air. Evan is dressed in
meriva

4,410 kJ

Explanation:

Gravitational Potential Enegry (GPE) is calculated as;

GPE = <em>m*g*h</em>                           where;

m = mass (kg)

g = gravity (m/s²)

h = height (meters)

= 90 * 9.8 * 5000

= 4,410,000‬ joules

= 4,410 kJ
