Photosynthesis takes place in chloroplast it is where the plants use the chlorophyll in the leaves to absorb sunlight and process it into food which helps the plant grow
Answer:
Magnet with a positive and a negative pole
Explanation:
A great analogy to demonstrate what a polar molecule looks like is to imagine a magnet. A magnet has one positively charged end and one negatively charged end, two poles, that is.
Imagine that we have a magnet of a shape of a prism (water molecule has a bent shape). The two base vertices of the face of the triangle are positively charged, that's because hydrogen is less electronegative than oxygen and, hence, the two hydrogen atoms are partially positively charged in a water molecule.
Oxygen is more electronegative than hydrogen meaning it has a greater electron-withdrawing force, so electrons are closer to oxygen within the O-H bonds. Oxygen, as a result, becomes partially negatively charged, so it's our negative pole of the magnet.
Answer: a) the C-C bond in : covalent
b) the KI bond in KI : ionic
c) NB bond in : polar covalent
d) the CF bond in : polar covalent
Explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.
An ionic bond is formed when an element completely transfers its valence electron to another element. This bond is formed between a metal and an non-metal.
a) the C-C bond in : covalent as there is no diffrence in electronegativity
b) the KI bond in KI : ionic as potassium transfers electron to iodine.
c) NB bond in : polar covalent as there is difference in electronegativity
d) the CF bond in : polar covalent as there is difference in electronegativity
Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, theexhaust<span> from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.</span>
Liquids Characteristics,<span> Liquid metal flows to fill the mold. As it cools, it solidifies. Once it is cool enough, it can be removed from the mold as a solid. The ability to flow is one characteristic that is different in solids than liquids. </span>
