This chart shows the global temperature anomaly (the difference of the expected temperature and the actual temperature) over a span of 130 years. which facts related to climate change does the chart reveal? ! there is more than one answer! (earth science) 20 points.
a. from 1975 to 2010, temperatures on earth were higher than normal.
b. from 1880 to 1940, temperatures on earth were higher than normal.
c. the 10 warmest years in the time span all occurred in the 2000s.
d. the coolest year in the time span occurred in 1945.
e. temperatures on earth do not fluctuate from year to year.

a. From 1975 to 2010, temperatures on Earth were higher than normal.

Explanation:

Hello,

Based on the graph's tendency and behavior, an evident outgrowth in temperature is shown from 1975 to 2010 since the temperature anomaly passed from 0°C to more than 0.5 °C during this time span.

Best regards.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
