Answer:
a light ray will always A light ray will always reflect away from a surface at an angle equal to the angle at which it struck the surface
Explanation:
it sound more formal and just plainly better
Answer:
The correct statements are a denovo anabolism of nucleotides d myosin action during muscle contraction e membrane transport that maintain levels in the cell.
Explanation:
ATP or adenosine tri phosphate is an high energy compound.The hydrolysis of ATP helps to drive many thermo dynamically unfavorable reaction.The processes which are coupled to the de phosphorylation of ATP are given below.
1 De novo synthesis of nucleotides that requires energy in form of ATP.
2 During muscle contraction the sliding of thick filaments or myosin over thin filament or actin requires energy derived from the hydrolysis of ATP.
3 Membrane transport basically active transport helps in the uphill transport of ions that requires free energy in form of ATP.
For this, you need to know 1) the mass of the hydrate and 2) the mass of the anhydrous salt. Once you have both of these, you will subtract 1) from 2) to find the mass of the water lost.
From the problem, you know that 1) = 2.000 g.
Now you need to find 2). You know that your crucible+anhydrous salt is 5.022 g. To find just the anhydrous salt, subtract the mass of the crucible (3.715 g).
1) = 5.022 g - 3.715 g = 1.307 g
Now you can complete our original task.
Mass H2O = 2) - 1) = 2.000 g - 1.307 g = 0.693 g.
The molecular geometry is square planar.
According to the Valence Shell Electron Pair Repulsion theory (VSEPR), the shape of a molecule is determined by the number of valence electrons surrounding the outermost shell of the central atom in the molecule.
In this case, the expected geometry based on VSEPR theory is octahedral. However, the lone pairs on opposite sides of the four single bonds leads to a square planar molecular geometry.

The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 = 
= 
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
