Hope this helps. (:
Answer:
Explanation:
Which of the following elements would lose an electron easily?
In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron
Answer: In the possible source of error goes: Changing two variables at once to increase rate of data collection, Taking turns with lab partners performing different tasks in an experiment, Measuring millimeters with an ordinary meter stick
In the good experimental practice goes: Measuring in standard metric units, Doing repetitive trials of the same experiment, changing the angle of a ramp in an experiment by constant intervals
Explanation: hopefully this helps i got them right so it guaaranteed you will get this right aswell.
Answer:
Back down to earth
Hot air balloons don't have pre-planned landing spots due to the fact they travel where the wind takes them. Instead, our pilots will look for a suitable open space and bring their balloon to land in a safe and controlled manner, fully compliant with aviation law.
Explanation:
In the structure of propane, CH3-CH2-CH3, there are 10 total bonds. Two carbon-carbon single bonds, and eight carbon-hydrogen single bonds. Each of these single bonds is also known as a sigma bond. Every hydrogen atom in this molecule uses an s-orbital to form bonds.
Each carbon atom in this molecule forms four sigma bonds. The electrons of each carbon atom are found in one s-orbital and three p-orbitals. However, when forming sigma bonds, the carbon atoms combine the four atomic orbitals into four molecular orbitals. This results in each carbon now having four hydridized sp3 orbitals. Therefore, each carbon atom is sp3 hybridized.
Now, when forming a sigma bond, the hybrid orbitals are used in the bonding. So for each C-H bond in this structure, the sigma bond is composed of an sp3 orbital from the carbon, and an s-orbital from the hydrogen. In the case of the C-C bonds, each sigma bond is simply a combination of two sp3 orbitals, one from each carbon.
