Answer:

Who: Svante Arrhenius.

When: Claimed in 1896 that fossil fuels has a negative effect on our atmosphere.

How: Svante Arrhenius proved that fossil fuels had a negative effect by calculating the output of buildings that emit fossil fuels, and lead to the conclusion by his calculations that the industry might one day bring global warming. Svante Arrhenius' theory of electrolytic dissociation and his model of the greenhouse effect also helped him to prove that his remarks about fossil fuels and global warming is true.

A 32.8 g iron rod, initially at 22.4 C, is submerged into an unknown mass of water at 63.1 C, in an insulated container. The fin

laila [671]

Answer:

mass water = 32.4 g

Explanation:

specific heat iron = 0.450 J/g°C

specific heat water = 4.18 J/g°C

32.8 x 0.450 ( 59.1 - 22.4) + mass water x 4.18 ( 59.1- 63.1)=0

541.7 - mass water x 16.7 = 0

mass water = 32.4 g

How to solve what volume of 12.0 m hcl is required to make 75.0 ml of 3.50 m hcl?

pochemuha

75mL=0.075L

Molarity=moles/Liters
Moles=0.075(3.50)
=0.2625

Since the number of moles never changes,
we know there are 0.2625moles (or 0.26) in the 12M HCl.
0.2625/12=0.021875L

(0.022L)
