Answer: H₂O is just water
Explanation:
Answer:
h2o is a water which is a clear, colorless, odorless, tasteless liquid that freezes into ice below 0°C and boils above 100°C.
What units are carbon emissions measured in?
Answer:
GHG emissions are often measured in carbon dioxide (CO2) equivalent. To convert emissions of a gas into CO2 equivalent, its emissions are multiplied by the gas's Global Warming Potential (GWP).
Your mom buys you a helium balloon at the circus. It has a volume of 4.00 liters at STP. What mass of helium (He), expressed in grams, does this balloon contain?
Answer:
2.8 g
Explanation:im not 100%
According to ideal gas equation and STP conditions, mass of helium is 7.04×10[tex]^-2[/tex] g.
What is ideal gas equation?The ideal gas equation is a equation which is applicable in a hypothetical state of an ideal gas.It is a combination of Boyle's law, Charle's law,Avogadro's law and Gay-Lussac's law . It is given as, PV=nRT where R= gas constant whose value is 8.314.The law has several limitations.The law has been proposed by Paul Emile Clapeyron, a physicist and an engineer in 1834.The law is applicable to only ideal gases at all temperature and pressure.
In the given problem, pressure= 1 atmosphere , volume=4 liters, molar mass= 4 g/mole ,R=8.314 , T= 273 K.
mass= PV×molar mass/RT=1×4×4/8.314×273=16/2269.722=7.04×10[tex]^-2[/tex] g.
Thus, the mass of helium gas is 7.04×10[tex]^-2[/tex] g.

which molecule has zero polarity
Answer:
Carbon dioxide
Explanation:
The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented this way, they cancel out and the overall molecular polarity of CO 2 is zero.
Answer:
CO2 has zero polarity

Binary molecules have
A) multiple (2+) or many elements bonded ionically & covalently.
B) 2 elements ionically bonded.
C) 2 elements covalently bonded.
D) 1 element covalently bonded.
Answer:
C
Explanation:
It is formed as a result of a reaction between two non-metals
Correctly predict the ionic compound that would form between the atoms rubidium (Rb) and oxygen (O).
Answer:
Rb2O
Explanation:
Rb is a 1+ element and Oxygen is a 2- element. To have a neutral overall charge you must change the molar ratio to have 2 (1+ elements) and 1 (2- element). Together add to 2+(-2)=0. So the overall product is neutral.
A chamber contains equal molar amounts of CO, CO2, N2, and O2. If the total chamber pressure is 3.00 atm, then the partial pressure of CO2 is
Answer:
[tex]P_{CO_2} = 0.75 atm[/tex]
Explanation:
[tex]P_{total} = P_{CO} + P_{CO_2} + P_{N_2} + P_{O_2}[/tex]
Since there's equal molar amounts we can conclude that
[tex]P_{CO_2} = P_{CO} = P_{N_2} = P_{O_2}[/tex]
So,
[tex]P_{total} = 4P_{CO_2}\\3.00 atm = 4P_{CO_2}\\P_{CO_2} = \frac{3.00 atm}{4} = 0.75 atm[/tex]
How much heat does your body lose when 6.35 g of sweat evaporates from your skin at 25 ∘C ? (Assume that the sweat is only water.) The heat of vaporization of water at 25 ∘C is 44.0 kJ/mol .
Answer:
15.52 kj
Explanation:
H2 O mole wt ~ 18 gm
6.35 gm is 6.35 gm /18 gm/mole = .353 moles of H2O
.353 moles * 44 kj/mole =
