Answer:

<u>Who: </u>Svante Arrhenius.

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

<u>How:</u> 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.

<u>Where:</u>

I cannot find any source that mentions the where. What do you mean by where?

I hope my other information help you. I apologies to only be able to answer partially.

What is the mass of a bar of aluminum with length 5.3cm, width 0.32 cm and height 2.34cm? The density of aluminum is 2.70g/cm3.
Tatiana [17]

Answer:

<h2>mass = 10.72 g</h2>

Explanation:

Density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

Making mass the subject we have

mass = Density \times volume

From the question

Density = 2.70 g/cm³

We assume that the aluminum is a cuboid

and volume of a cuboid is given by

Volume = length × width × height

length = 5.3 cm

width = 0.32 cm

height = 2.34 cm

Volume = 5.3 × 0.32 × 2.34 = 3.97 cm³

Substitute the values into the above and solve for the mass

We have

mass = 2.70 × 3.97

We have the final answer as

<h3>mass = 10.72 g</h3>

Hope this helps you

What defines a mixture?
erica [24]

B is your best answer because a mixture is when two or more things combine but not chemically. Take soup for example you take out all the pieces because they didn't combine together and just become 1 thing they still have parts. You can still take the noodles, you take the fish or meat out still, you take the broth away to.
