Can someone help me with these gas laws problems? I need help seeing it step by step. I've been trying but my answers don't make any sense!

1) A plastic syringe with a movable plunger is capped, trapping 13.2 mL of gas. If this gas exerts a pressure of 1.03 atm when the temperature is 24.8OC, determine the variable that changes and calculate its new value if the syringe is placed in a beaker of cold water with a temperature of 5.82OC.

Consider a helium balloon inside a parked car on a hot day where the temperature is 72.0OC and the pressure is 1.02 atm. When the balloon is taken outside where the temperature is 34.0OC its volume is measured as 2.21 L. What is the change in the volume of the balloon compared to when it was in the car?

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

a polar bond is formed when electrons are shared unevenly between atoms

b. is the answer hoped i
