<span>A red ladybug appears red in white light, red in red light, and black in blue light.
When a ladybug is red it means that its shell reflects the red light, or the radiation between 650-700 nm, from the visible spectrum. A white light is composed of all colours, the whole visible spectrum, therefore, the ladybug shell will reflect the red colour. When considering a red light over a red ladybug, the ladybug will again appear red because the spectrum in which there is reflection of colour from its shell is present. On the other hand, when blue light is put over a red ladybug, the ladybug will appear black as there is no light that its shell can reflect.</span>
Answer:
The answer is C.
Explanation:
An ion is unlike a neutral atom in the fact that it has a charge. Because electrons are negatively charged, an atom becomes more positive if electrons are lost.
Answer:
this answer your question
If the heat change of the surroundings (such as the solution the reaction is occurring in) is determined to be 2.7 kJ, what is the heat change of the reaction (qrxn)?
Answer: First of all we can conclude that this is an exothermic reaction. The reason being that an exothermic reaction is one that produces a temperature increase in a isolated system giving off heat to the surroundings. Therefore the heat of the reaction is a negative quantity (qrxn < 0).
I hope it helps, Regards.
Answer: a. gamma rays
Explanation:
Scientists are able to use gamma rays to determine the composition of planets and other celestial bodies.
Special equipment exists that can measure gamma rays emitted by atoms on a planet's surface when it is struck by cosmic rays thus enabling us (humans) to understand more of the universe.
