It uses the voltages and sound freq. in the air to measure the wave lengthths
Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.
Answer: Heyo Kenji Here! Here's your answer- when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Explanation: ~Hope this helps!~
Have a nice day!

Answer: The number of moles of 
reacted was 0.229
Explanation:
According to ideal gas equation:
P = pressure of gas = Total pressure - vapor pressure of water = (749 - 23.8) mm Hg= 725.2 mm Hg = 0.954 atm (760mmHg= 1atm)
V = Volume of gas = 5.87 L
n = number of moles = ?
R = gas constant =
T =temperature =
According to stoichiometry:
1 mole of 
is produced by = 1 mole of
Thus 0.229 moles of is produced by = 
moles of
Thus number of moles of reacted was 0.229
Answer:
Type: M
Name: Dixytrogen Pentasulfide
Molar Mass:
X*2 = Number * 2 = Number
S*5=32.066*5=160.33
Number + 160.33 = Molar Mass (g/mol).
(The mass for Xytrogen is not present).
Explanation:
Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.
The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).
The molar mass is explained above. You need to multiply the mass of each element by the number of elements present in the compound. The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.
Hope this helps.
