Draw a dot and cross diagram to show the arrangement of outer electrons in a molecule of silicon chloride. By reference to their structure, explain how the particles in a piece of metal are held together and how the shape of the metal can be hanged without breaking it. (You may use a diagram in your answer)

The mystery fuel speedster! (Homework ) For fun, you build an explosive car with your little brother by attaching wheels to an empty windshield washer container. To advance it, you add 1.20 ml ( = 0.7915 g/ml) of a liquid but volatile fuel into the container. You close the cap and shake to evaporate the liquid. Finally, you place the car on its wheels, remove the cap and insert a burning wooden rod into the container. A flame suddenly comes out of the car, which is propelled with good speed in front of your little brother surprised, but all upset by the maneuver. The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol. During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too. The volume of the windshield washer container used is 4.00 litres. Useful Info: There is 21.0% gaseous oxygen in the air and initial conditions…

Serious injuries can occur when students attempt to force the pipet bulb onto the top of the pipet. The blue bulbs we use in lab are not meant to attach to the pipet, they simply rest on the top. Which of the following items will help you be more successful when working with a pipet? Group of answer choices Gently place the pipet bulb on the pipet Keep the tip of the pipet submerged when filling It is best to fill the pipet to a point just above the calibration line, then adjust the volume by slowly releasing liquid. Liquid should fully fill the pipet bulb The more aggressive you are with the pipet bulb, the quicker you will get out of lab
