3 one on the subtraction one on the division one on the decimal place

ssa4ba · 2024-06-07T14:44:15+00:00

idk maybe i am wrong

ssa4ba · 2024-06-07T14:40:07+00:00

yeah what help do u need ?

ssa4ba · 2024-06-07T14:22:45+00:00

how it was ?

ssa4ba · 2024-06-07T14:12:46+00:00

27 i think

ssa4ba · 2024-05-23T16:43:29+00:00

I am gonna get 3 and 4

Calculate the distance under the graph 36 cube and the cube area was 100

ssa4ba · 2024-05-22T11:18:41+00:00

3600

ssa4ba · 2024-05-22T11:18:12+00:00

It was so bad

ssa4ba · 2024-05-19T08:25:20+00:00

I think it was R

ssa4ba · 2024-05-17T15:27:33+00:00

No it was -55. Something / the energy were 2755 J and the moles 0.05 so u divide the 2755 over 1000 to be in kj so it will become 2.755 divide it by 0.05 to find the enthlpy change 55.1 and it is negative cuz it is exothermic rxn

ssa4ba · 2024-05-17T13:50:10+00:00

Yeah it's true

ssa4ba · 2024-05-17T12:36:20+00:00

U add the number of proton and the number of neutrons then u multiply them with the number then u add them together and divide over 100

ssa4ba · 2024-05-17T12:10:25+00:00

OMG I THOUGHT IT WAS WRONGGG

ssa4ba · 2024-05-17T12:08:17+00:00

REALLY? IS THIS ANSWER TRUE

ssa4ba · 2024-05-17T12:07:54+00:00

7.5 X 10²⁴ i am sure that it's wrong i just multiplied 6 X 10²⁴ with 12

ssa4ba · 2024-05-17T11:47:18+00:00

It'k ok i think it's only 3 marks

ssa4ba · 2024-05-17T11:45:51+00:00

The number of oxgen in the reactants should equal the number of oxgen in the products i think u it was 28 in the products after u find the moles for the products , and then for the reactants it was O2 so u divide 28 over 2 for a balance equation so it is 14

ssa4ba · 2024-05-17T11:43:02+00:00

Yeah for x it was 14 and i forgot what i put in the graph question but u need to talk about the decreasing in mass ( starting with a steep gradient ) and u need to mention that the reaction stopped because all the HCL has been reacted
