Answer:
can u mark me brainliest
Explanation:
Following the Law
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions
Answer:
17.5% es la transmitancia de la solución problema
Explanation:
Basados en la ley de Beer que dice que:
La transmitancia de una solución es inversamente proporcional a su concentración.
Podemos hallar la transmitancia de una concentración problema sabiendo la concentración de una solución y su transmitancia:
Si una solución 0.0150M tiene una transmitancia de 35%
Y ahora la solución duplica su concentración, su transmitancia se disminuirá en la mitad, esto es:
35% / 2 =
<h3>17.5% es la transmitancia de la solución problema</h3>
The first rule is to use four digits in atomic weights and consider the calculated formula or molar mass as given with four significant digits. This rule is appropriate for beginners but has some disadvantages.
The second rule is to use all digits in the recommended atomic weights and to estimate the accuracy of the result from the number of decimal places or significant digits in these.
The third rule is to use all digits in the recommended atomic weights and to calculate the absolute maximum uncertainty of the result from the recommended uncertainties of the atomic weights. The uncertainty is rounded up to one (two) significant digit(s), and the formula or molar mass is rounded to the same absolute accuracy as the rounded uncertainty.
<span>The shininess of an element is also referred to as "metallic luster." The element that is most likely to have a metallic luster is B. rhodium.
Arsenic has a dull luster, chlorine and hydrogen are gases so they don't have luster.
