Drag the tiles to the boxes to form correct pairs. Use the Hertzsprung-Russell diagram to determine which condition describes each star. Use the arrows to help locate the stars.

A) Betelgeuse
B) the Sun
C) Sirius B

The star can no longer support nuclear fusion because it has exhausted its supply of hydrogen:

The star’s hydrogen supply is running low, so it is fusing hydrogen from outside the core:

The star is experiencing nuclear fusion at its core:

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

can i get the brainiest answer

i answered it first

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
