根据第一段“The villain in the atmosphere is carbon dioxide.(大气中的反派是二氧化碳)”可知,大气中的反派是二氧化碳。故答案为Carbon dioxide is the “villain” in the atmosphere. (2)题详解: 考查细节理解。根据第五段的“The sea level is rising very slowly from year to year. In all likelihood...
Plants make their cells principally out of carbon. They get their carbon by breathing in CO2and breaking off the oxygen, which they breathe out (and keep the carbon). So, plants are made of the carbon in carbon dioxide molecules, while the oxygen becomes the oxygen we and other animals br...

Carbon dioxide is a gas at room temperature while silicon dioxide is a solid because A carbon-oxygen bonds are less polar than silicon-oxygen bonds. B B van der Waals'forces are much weaker than covalent bonds. C carbon dioxide contains double covalent bonds while silicon dioxide contains singl...
Which atom is most likely to form a polar covalent bond with carbon? What is the Lewis structure for carbon? What is the formula for calcium carbonate? What group is fermium in on the periodic table? Which compound contains ionic bonds: N2O, Na2O, CO, or CO2?
Polar Covalent Bonds: A covalent bond where there is discernible electronegativity between two atoms. Dipole: A condition where the positive and negative charges between atoms are separate from each other. London Force: Instantaneous dipole creation that affects the electronegativity between atoms. It ...
C carbon-oxygen bonds are less polar than silicon-oxygen bonds. D van der Waals' forces are much weaker than covalent bonds. 相关知识点: 试题来源: 解析 DAnswer DCarbon dioxide is a simple molecules with weak can der waal's forces of attraction between molecules while silicon dioxide is...
However, when its concentration rises, it becomes pollutant because it results in global warming. The letter is quite dangerous because it is melt polar ice, raise the water level of oceans and submerge several coastal areas and islands. Show More ...
To determine which statements about carbon dioxide (CO2) are correct, let's analyze each statement step by step.Step 1: Analyze the first statement Statement: Carbon dioxide molecule behaves as a nonpolar molec
