2. Why would a calcium (Ca) atom be larger than a bromine (Br) atom even

1 answer:

3 0

Within a period, the atom size decreases with increasing group number (from left to right), since the nuclear charge and the number of external electrons increase within the period, but the number of shells does not. The electrons are more strongly attracted to the nucleus and are therefore closer to the nucleus.

When snow melts does its volume decrease or increase?

kompoz [17]

The volume of the snow decreases. This had happened because the snow is made up or comprised of water (H2O) and oxygen (O). When the snow starts melting, the air inside the snow discharges into the atmosphere and the water turn out to be a puddle on the ground.

The position of the equilibrium for a system where K = 6.4 × 10 9 can be described as being favoring ________________

geniusboy [140]

Answer:

to the right (products side)

Explanation:

The equilibrium constant K describes the ratio between the concentration of products and reactants at equilibrium. For a general reaction:

a A + b B → c C + d D

The equilibrium constant expression is:

$K = \frac{[C]^{c} [D]^{d} }{[A]^{a} [B]^{b} }$

A low value of K indicates that the concentration of products (C and D) is low in relation with the concentration of reactants (A and B).

Conversely, a high value of K indicated that the concentration of products is high compared with the concentration of reactants.

Since K = 6.4 × 10⁹ is a high value, the concentration of products is higher than the concentration of reactants at equilibrium. Thus, the position of the equilibrium is favored to the right.

How do scientists use light-years?

sveticcg [70]

Answer:

Scientists don't actually measure astronomical distances in light years. Rather, they measure them in a unit called the Parsec , and only convert to light years when they're talking to the general public . One light-year is the distance light travels through space in one year.
