They actually have the same amount of kinetic energy but the bus I would say is more cuz it weighs more mass, more mass means the more energy it's going to need.

A 4000 kg bus going 40 mph has more kinetic energy than a 2000kg car going 40 mph. tis cuz' KE=1/2*mass*velocity^2 so bus has higher 2x mass of car n 2x KE, even thou their speed is the same.

Write the balanced molecular equation for the neutralization reaction between hi and ba(oh)2 in aqueous solution. include physic
telo118 [61]
So, Ba is divalent. This means that each Ba(OH)2 requires two I in order to produce one BaI2 molecule.
The two hydrogens from the 2 HI molecules will combine with 2 OH of Ba(OH)2 forming 2 water (H2O) molecules.

The equation which illustrates this reaction in as follows:
<span>2 HI (aq) + Ba(OH)2 (s) ........> BaI2 (aq) + 2 H2O (l)
</span>where:
aq refers to aqueous state
s refers to solid state and
l refers to liquid state.

describe the law of conservation of energy and two examples of energy being transformed from one type to another.
VladimirAG [237]

Answer:

look in the explanation part

Explanation:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Balance the following chemical equation by providing the correct coefficients fe+h2so4 fe(so4)3 + h2
Dmitriy789 [7]

Answer:

2Fe + 3H2SO4 + Fe2(SO4)3+ 3H2

Explanation:

1. Fe (SO4) 3 is an incorrectly written formula because iron is trivalent as we can see by this three ahead of SO4. SO4 is divalent always.

2. since (SO4) is 3, this three shows us that there must be 3 in the reactants as well.

so now there is 3H2SO4

3. Since we have added 3 to one hydrogen we must add another. So now it's 3H2

4. and finally iron. In Fe2 (SO4) 3 we see this 2 in front of Fe which means it goes 2Fe.

Please help on science!! Will mark as brainliest!!
telo118 [61]

Answer:

6. yes  you can add more beans with the each sounding signal to the beaker because there is pattern of adding beans in the beaker and addition of double has the capacity of 20 vs 40 more beans in the beaker

7. you can add up two more lines in the table

90 vs 180

100 vs 200

8. This could not be possible . the growth of population does effect the resources like land and space and other things .

need more help let me know if you need to understand something again . Text me Thanks
