Uno de los componentes del “sal de uvas”, es el bicarbonato de sodio, es un sólido cristalino blanco, debido a su capacidad de neutralizar el exceso de ácido clorhídrico del estómago.
La acidez estomacal es ocasionada por un exceso en la producción de ácido clorhídrico (HCl) en el jugo gástrico del estómago. Uno de los componentes del “sal de uvas”, utilizada como antiácido, es el bicarbonato de sodio (NaHCO₃), es un sólido cristalino blanco, que neutraliza el exceso de ácido clorhídrico. La reacción de neutralización es:
HCl(aq) + NaHCO₃(aq) ⇒ NaCl(aq) + H₂O(l) + CO₂(g)

Answer:
IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.
Explanation:
The hypothesis is a testable explanation of a scientific investigation. It aims at predicting the outcome of the experiment. One feature of the hypothesis is that it must be testable. The hypothesis is usually written in an "IF, THEN" format.
This question is regarding an experiment to test the amount of vitamin C in fruit juice. The vitamin C is thought to be an effective preventative against common cold. Hence, the hypothesis connects the effect on common cold (dependent variable) with the amount of vitamin C (independent variable). The hypothesis can be written as:
IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.
Answer:
Explanation:the best guess I will go with is H but I might be wrong
<span>The </span>elements are arranged<span> in order of increasing atomic number. Vertical columns(called groups) contain </span>elements with similar properties. Horizontal rows called periods elements with<span> the same number of atomic orbitals(That's why Hydrogen and Helium are separated from the rest of the table).
Hope this helps:)</span>
Usually (ignoring transition metals, as they kinda get trickier), the element's valency can be found out by its group (column) number. Usually, we ignore the transition metal block while counting these columns, so Aluminium is in group 3, for example. Since Aluminium is in group 3, it has 3 valence electrons.
