Now molecules: Choose... molecules of H 2 + Choose... molecules of O 2 → Choose... molecules of H 2 O
Answers
2 H2 + O2 → 2 H2O
We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:
100 H2 + 50 O2 → 100 H2O
This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:
5,000 H2 + 2,500 O2 → 5,000 H2O
Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:
12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O
These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?
2 H2 + O2 → 2 H2O

empirical formula of c8h14
Answers
Answer:
C4H7
Explanation:
Empirical formula is defined as the simplest ratios of atoms present in the compound.
The empirical formula for C8H14 is C4H7 as if you multiply each coefficient of C4H7 by 2, it will become C8H14. The chemical name of C8H14 or C4H7 is 1-Methylcycloheptene.
Hence, the correct answer is "C4H7".
If sodium (Na) bonds with chlorine (Cl), which statement is true?

formed.

Answers
Answer:
First Statement is correct
Explanation:
An electron is transferred from sodium to chlorine and ionic bond is formed.
Hope it help!!
If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.
What is ionic bond ?The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.
The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.
Thus, option A is correct.

Why Doesn't The Earth Usually Feel Solar Winds?
Answers
Answer:
When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.

There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.
Explanation:
option (B) is right
Metals used in batteries undergo a chemical reaction with the electrolyte and free the electrons. The flow of electrons produces the electric current.
What is the electrical battery?An electric battery can be described as a source of electric power containing of one or more electrochemical cells with external connections.
The positive terminal of the battery is the cathode and its negative terminal is the anode. The negative terminal can be denoted as the source of electrons that will flow via an external electric circuit to the positive terminal.
A redox reaction transforms high-energy reactants into lower-energy products, and the free-energy difference provides the external circuit as electrical energy.
Each cell of the battery contains two half-cells connected in series by an electrolyte containing metal cations. One half-cell includes an electrolyte and the negative electrode and the other half-cell includes an electrolyte and the positive electrode. Cations are reduced at the cathode, while metal atoms are oxidized at the anode.

Answers
Answer:
D
Explanation:
because the rest don’t make any sense
A light-year unit is very large and distances in space are very large. Therefore, the correct option is option D.
What is distance?No matter the direction of the journey, distance is the overall path that an item in motion has traveled. Since just the length of the path travelled is calculated as well as the motion's direction is ignored, distance is referred to as a scalar number. The distance can only ever be positive; it can never be 0 or negative.
Displacement generally defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into consideration both the directions of the motion and the amount of the changing position. Displacement may be zero, positive, or negative. A light-year unit is very large and distances in space are very large.
Therefore, the correct option is option D.
