How do I explain this? I'm a little stuck. :/
Dimas [21]

Answer:

Not balance.

Explanation:

Chemical equation:

K + Cl₂    →    KCl

The given equation is not balance because there are one potassium and two chlorine atoms on left side of equation while on right side there are one potassium and one chlorine atom present.

Balance chemical equation:

2K + Cl₂    →    2KCl

the equation is balance now because there are two potassium and two chlorine atoms on left side of equation and two potassium and two chlorine atoms are also present on right side.

how many grams of silver medal could be recovered from a reaction of 50 g silver nitrate and copper metal
Likurg_2 [28]

Answer:

Answer is: mass of copper is 127 grams.

Balanced chemical reaction: Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s).

m(Ag) = 432 g.

n(Ag) = m(Ag) ÷ M(Ag).

n(Ag) = 432 g ÷ 108 g/mol.

n(Ag) = 4 mol.

From chemical reaction: n(Ag) : n(Cu) = 2 : 1.

n(Cu) = 4 mol ÷ 2 = 2 mol.

m(Cu) = n(Cu) · M(Cu).

m(Cu) = 2 mol · 63.5 g/mol.

m(Cu) = 127 g

Gamma, beta and alpha radiation are all alike because:
timama [110]
Alpha, beta and gamma radiation are all types of radiation that can be emitted from the nucleus of an atom. Apart from this they are different. Alpha radiation consists of a helium nucleus, beta radiation consists of an electron (or positron) and gamma radiation consists of very high energy electromagnetic radiation.

MatroZZZ [7]
Lets say foxes hunt rabbits. If their are too many foxes then they will compete for the rabbits. The rabbits get outnumbered by the amount of foxes so the foxes kill all the rabbits and the rabbits could eventually go extinct.
