the reaction below shows the combustion of butane (c4h10). why is the mole ratio (8 moles co2/2 mol c4h10) used to determine the amount of carbon dioxide (co2) produced when butane (c4h10) combusts in excess oxygen? (1 point)

c4h10 + o2 yields co2 + h2o + heat

butane has a mass that is 4 times greater than co2, so only 2 moles of c4h10 are needed to produce 8 moles of co2.

carbon dioxide has a volume of about one-quarter that of c4h10, so 4 moles of co2 are needed to react with each mole of c4h10.

during combustion, co2 is approximately 4 times more reactive than c4h10, so less c4h10 will participate in the reaction.

when the chemical equation for butane combustion is balanced, 2 moles of c4h10 are needed to produce 8 moles of co2.

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.

there all right good

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
