H₂O, which represents a molecule of water, consists of three atoms: two hydrogen atoms (H) and one oxygen atom (O). Therefore, H₂O contains a total of three elements: hydrogen and oxygen.
What is H₂O?H₂O represents a molecule of water. The "H" stands for hydrogen, and the "O" stands for oxygen.
Hydrogen (H) is a chemical element with the atomic number 1. It is the lightest and most abundant element in the universe. Hydrogen atoms consist of a single proton in the nucleus and one electron in orbit around the nucleus.
Oxygen (O) is a chemical element with the atomic number 8. It is a highly reactive and abundant element, making up a significant portion of the Earth's atmosphere and the compounds found on Earth. Oxygen atoms consist of eight protons in the nucleus and eight electrons in orbit around the nucleus.

A car accelerates from 10 km/h to 80 km/h in 8.0 seconds. Determine the car’s acceleration in m/s2.
Answers
Answer:
The difference in velocity divided by rate = acceleration.
80 - 10 = 70km/h
60 sec. per hour, so 70 × 60 = 4,200 km/s
4.200/8=525
520/60 = 8.6666666667 km/h
Explanation:
Not the answer but hope it puts you in the neighborhood.
The resultant acceleration of the car is 2.43 m/s².
What is acceleration?Acceleration is define as the rate of change of velocity with respect to the time and it will be calculated as:
Acceleration = Velocity / Time
Given that, velocity of car = 80km/h - 10km/h = 70km/h
As we know that 1 km = 1000m
and 1 hour = 3600 sec
So that 70km/h = 19.4 m/s
Given time = 8 sec
Now putting values on the acceleration equation, we get
Acceleration = 19.4 m/sec / 8sec = 2.43 m/s²
Hence required acceleration is 2.43 m/s².

Answers
Answer:
The present water by weight for the hydrate = 45.2%
Explanation:
From the given information;
The present water by weight = (weight of the water/ total weight of the hydrate) × 100
The present water by weight = (11.3/25) × 100%
The present water by weight = 0.452 × 100%
The present water by weight for the hydrate = 45.2%

Which substance is made up of molecules that can have temporary dipoles?
a. CO2
b. NH3
c. N2
d. H2O
Answers
Answer:
Molecules that contain dipoles are called polar molecules and are very abundant in nature. For example, a water molecule (H2O) has a large permanent electric dipole moment.
so it is (D). H2O
Explanation:
Based on the nature of intermolecular forces, the molecule that can have a temporary dipole is nitrogen gas, N2.
What are temporary dipoles?Temporary dipoles are created when electrons revolving around the nucleus, spontaneously come into close proximity resulting in an uneven distribution of electrons, thereby creating a temporary dipole due to unbalanced charges.
Temporary dipoles can initiate weak intermolecular attraction between neighboring molecules such as van der Waal's forces.
Temporary dipoles can occur in non-polar molecules such as nitrogen gas resulting in the ability of nitrogen to be liquefied.
Therefore, the molecule that can have a temporary dipole is nitrogen gas, N2.

Answers
Answer:
C₂H₄O
Explanation:
The empirical formula of a compound is defined as the simplest whole number ratio of the atoms present in a molecule. As we have in the molecule Carbon, Hydrogen and Oxygen to find the simplest ratio we need to divide each number of moles in the moles of Oxygen (The lower number). As follows:
C = 0.5mol C / 0.25mol O = 2
H = 1 mol H / 0.25mol O = 4
O = 0.25mol O / 0.25mol O = 1

Show how the limiting reactant is determined for 3.80 g of magnesium reacting with 12.5 g of oxygen.
Answers
Answer:
Magnesium is the limiting reactant.
Explanation:
The balanced reaction is:
2 Mg + O₂ ⇒ 2 MgO
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following quantities participate in the reaction:
Mg: 2 molesO₂: 1 moleMgO: 2 molesBeing the molar mass:
Mg: 24.31 g/moleO₂: 32 g/moleMgO: 40.31 g/moleThen the following quantities of mass participate in the reaction:
Mg: 2 moles* 24.31 g/mole= 48.62 gO₂: 1 mole* 32 g/mole= 32 gMgO: 2 moles* 40.31 g/mole= 80.62 gThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction. You can use a simple rule of three as follows: If by stoichiometry of the reaction 32 grams of oxygen react with 48.62 grams of magnesium, 12.5 g of oxygen will act with how much mass of magnesium?
[tex]mass of magnesium=\frac{12.5 g of oxygen*48.62 grams of magnesium}{32 grams of oxygen}[/tex]
mass of magnesium= 18.99 grams
But 18.99 grams of magnesium are not available, 3.80 molesgrams are available. Since you have less mass than you need to react with 12.5 grams of oxygen, magnesium will be the limiting reagent.
