Agroup of engineers run a trial test on a space probe built for measuring the surface temperature of the sun. after the trial, the engineers realize that the probe melted and failed to collect the needed data. what should the engineers do next?

Explanation:

Probe melted because the material used in the making of the probe was not that much resistant to the high temperature of the sun. So, now they have to design a probe with material which should have very high resistance to a high temperature so that the probe does not get melt again.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
