Answer:
Chlorine
Explanation:
Even though chlorine is highly electronegative, the best answer is no, and in this class we will consider chlorine not to form hydrogen bonds (even though it has the same electronegativity as oxygen). This is because chlorine is large and its lone electron is in a diffuse orbital, covering a large area, and thus do not have the high charge density to act as a strong hydrogen bond acceptor. But it does form weak hydrogen bonds in solid crystalline hydrogen chloride at very low temperatures.
Answer:
During exercise, your body may need three or four times your normal cardiac output, because your muscles need more oxygen when you exert yourself. During exercise, your heart typically beats faster so that more blood gets out to your body.
The formula for distance is
distance = speed (velocity) * time
2km/h * 1.5hrs = 3km
Answer:
Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.
