A sample of gas has a pressure of 742 torr. What is the pressure in atmospheres?
ycow [4]

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

\frac{742 torr}{1}*\frac{1 atm}{760 torr}=0.976316=0.976 atm

(torr cancels out and we're left with atm)

Hope this helps :)

when copper wires are made, a copper rod is pulled into a narrower wire. Explain how metallic bonding allows this to happen
777dan777 [17]

Answer:

possibly because of the malleability of metals

Explanation:

In metallic bonding, electrons are delocalized and move freely among nuclei. When a force is exerted n the metal, the nuclei shift, but the bonds do not break, giving metals their characteristic malleability.
