A. the polarity of the water molecule because the balloon is negatively charged and the positive hydrogen end of the water molecules are attracted to it

Answer is A. The polarity of the water molecule

Water is a polar molecule due to an uneven distribution of electron density. Water has a partial negative charge near the oxygen atom and partial positive charge near the hydrogen atoms. Thus, dipole moment is created when there is a charge separation between the molecules. The dipole moment of water is 1.85. Therefore, when the charged balloon is placed close to the stream of water, it cause all the molecules of water to bend towards the balloon which has static charge on it.

Responder:

Hipótesis científica

Explicación:

El procedimiento de representar un fenómeno que no puede explicarse a la luz de la teoría científica actual se llama hipótesis científica.

Generalmente, en el orden de los Métodos Científicos, las observaciones y las preguntas son los primeros pasos. Sin embargo, para proporcionar posibles explicaciones al fenómeno obtenido al hacer preguntas y observaciones, se necesita una suposición o sugerencia. Esta es la suposición científica: para que sea válida, debe ser refutada, basada en la observación cuidadosa del fenómeno.

su esencia es predecir los posibles resultados de un intento de experimentos y después de realizar los experimentos para confirmar si el resultado está de acuerdo con la predicción.

Answer:

Scientific hypothesis

Explanation:

The procedure of representing a phenomenon which can not be explained in the light of the present scientific theory is called scientific hypothesis.

Generally in the order of Scientific Methods observations and asking of questions are the early steps.How ever, to provide possible explanations to the  phenomenon  by asking questions and observation , a guess or suggestion is needed. This is the scientific guess,For it to be valid,it must be refuted, based on the careful observation of the phenomenon.

its essence is to predict the possible outcomes of an intending experiments and after conducting  the experiments to confirm if the outcome agrees with the prediction.

Veseljchak [2.6K]
<span>The placenta is the organ which supplies an infant with oxygen, nutrients, and waste excretion throughout its gestation period; this is accomplished via the umbilical cord, which serves as a conduit between the infant, at its navel, and the placenta itself, which is attached to the mother's uterine wall.</span>

Which is the best explanation of how catalysts are used in chemical reactions A. Catalysts are needed for every chemical reactio
kicyunya [14]

Answer:

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions

Explanation: I don't know if this will help but hopefully it does
