Answer is: tomatoes is thousand (1000) times more acidic than water.
pH(tomato) = 4.00.
pH(water) = 7.00.
pH = -log[H⁺<span>].
</span>[H⁺] = 10∧(-pH); concentration of hydrogen ions.
[H⁺] = 10⁻⁴ M = 0.0001 M; tomato.
[H⁺] = 10⁻⁷ M = 0.0000001 M; water.
[H⁺](tomato) /[H⁺](water) = 0.0001 M ÷ 0.0000001 M.
[H⁺](tomato) /[H⁺](water) = 1000.
The ozone layer is a shield district of Earth's stratosphere that ingests a large portion of the Sun's bright radiation. It contains a high grouping of ozone (). It contains atoms of oxygen that keep the environment from hurtful beams that are available in the space and boundless by the sun, for instance, bright beams.
The ozone opening is to a greater degree a downturn, less a gap in the windshield. The ozone doesn't vanish through the layer, nor is there a uniform diminishing of the ozone layer. Also, it was found in 1913 by the French physicists Charles Fabry and Henri Buisson.
In 2017, the ozone opening arrived at a size of 7.6 million square miles (19.7 square kilometers) before beginning to recuperate. In 2016, the gap developed to 8 million square miles (20.7 square kilometers).
Answer:
Coefficient: number balancing sulfuric acid in a chemical reaction.
Subscripts: number of atoms of each element forming the compound.
Explanation:
Hello!
In this case, since sulfuric acid is a molecule containing hydrogen, sulfur and oxygen in the following way:
- Two hydrogen atoms.
- One sulfur atom.
- Four oxygen atoms.
We can notice the 2 at H represents those two hydrogen atoms, the subscriptless S represent that 1 sulfur atom and the 4 at O represents those four oxygen atoms.
Moreover, since the molecules is given as 7 H2SO4
; from stoichiometry, we infer that every number preceding the molecule stands for a coefficient which is used to balance a undergoing chemical reaction reaction.
Best regards!
Answer: Gravity
Explanation: The answer is gravity: an invisible force that pulls objects toward each other. ... So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
