Answer:

-3m+7m =  4m

Explanation:

As he walks south, he is going down 3m (-3m). Then he walks up 7m (+7m).

When 2 grams of hydrogen (h2) react with 32 grams of oxygen (O2) the reaction yields hydrogen peroxide (h2o2) how many grams of
MissTica

as per the reaction we have

H_2 + O_2 ---> H_2O_2

so here 1 mole of H2 react with 1 mole of O2 and give 1 mole of H2O2 as the product

now we will find the moles of given reactant

moles of H2

n_1 = \frac{2}{2} = 1 mole

moles of O2

n_2 = \frac{32}{32} = 1 mole

so here both present in 1 mole each hence the product will also formed 1 mole

so here we have

n = 1 mole H2O2 will form

so mass of the product

mass = moles* molecular mass

m = 1 * (2 + 32)

m = 34 g

so the product mass will be 34 g

¿Una corriente eléctrica sin resistencia puede fluir constantemente sin fuente alguna de potencia? Explique.
frosja888 [35]

Answer:

No.

Explicación:

No, una corriente eléctrica sin resistencia no puede fluir constantemente sin ninguna fuente de energía porque la fuente de energía proporciona electrones para el flujo continuo de corriente en el circuito. Si fluye corriente por el cable, debe haber resistencia en el circuito. La fuente de energía proporciona corriente eléctrica continua al cable para que fluya y el cable tiene resistencia, por lo que parte de la corriente eléctrica se pierde durante su flujo debido a esta resistencia. Entonces podemos decir que la fuente de energía es necesaria para el flujo constante de corriente eléctrica.
