Answer:

Water and Salt

Explanation:

A neutralization reaction occurs when an acid and a base react to produce water and a salt, and it entails the formation of water from the mixture of H+ and OH- ions.

Answer:

NaCl and water is formed when acid reacts with base

this is the answer of your question .

Hope it helped you

Answer:

[tex]P_{CO_2}=25mmHg[/tex]

Explanation:

Hello there!

In this case, according to the Dalton's law, which explains that the total pressure of a gaseous system equals the sum of the partial pressures of the gases composing, for the gaseous mixture composed by oxygen, nitrogen and carbon dioxide it would be possible to write:

[tex]P_{tot}=P_{N_2}+P_{O_2}+P_{CO_2}[/tex]

Now, given the pressure of the system and those of oxygen and nitrogen, we calculate that of carbon dioxide as shown below:

[tex]P_{CO_2}=P_{tot}-P_{N_2}-P_{O_2}\\\\P_{CO_2}=250mmHg-50mmHg-175mmHg\\\\P_{CO_2}=25mmHg[/tex]

Best regards!

Answer:

warm water holds the least amount of dissolved oxygen, so I would assume the answer would be D. a small pond could heat up easily. in addition, the water is calm and not moving in a pond

Answer:

Acceleration Of B IS greater

Explanation:

Acceleration of ( A) =20÷5 =4

Acceleration of (B) =5

plz write question properly. Its not understandable.

Answer:

5:4

Explanation:

The equation given is balanced. There are 5 O2's on the left (reactant side) and then 4 H2O's on the right (product side). Thus, it's a 5:4 ratio.

Explanation:

Answer: Ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Explanation:

Compounds formed by transfer of electrons from one atom to another are called ionic compounds.

For example, sodium atom on losing its one valence electron forms [tex]Na^{+}[/tex] ion and when a chlorine atom gains this electrons then it forms [tex]Cl^{-}[/tex] ion. These ions when come closer then an electrostatic force of attraction will pull them together forming NaCl compound.

Therefore, one atom of sodium is chemically combining to one atom of chlorine to form NaCl.

As the forces present between atoms of an ionic compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Thus, we can conclude that ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Ionic compounds are formed when there is a donation of an electron from one element to another that receives the electron. This causes the donating atom to attain a positive charge and the receiving atom to attain a negative charge. The ions thus formed are held by strong electrostatic forces that hold them together.

Explanation:

The galaxy is the component of the universe which  contains all of the other components and would have the greatest mass.

A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity.The word is derived from the Greek galaxias , literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars,each orbiting its galaxy's center of mass.

Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.

There are seven periods in the modern periodic table.

Answer:

Seven periods

Explanation:

There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.
