1 answer:

6 0

1. Group 1 (Alkali Metals)Group 2 (Alkaline Earth Metals)Group 13 (Boron Group)Group 14 (Carbon Group)Group 15 (Nitrogen Group)Group 16 (Chalcogens)Group 17 (Halogens)Group 18 (Noble Gases)
2.The elements in each group have the same number of electrons in the outer orbital
3.Group 2 elements share common characteristics. Each metal is naturally occurring and quite reactive.
4.There are 18 numbered groups in the periodic table
5.many characteristics are common throughout the group

What is the volume, in milliliters, occupied by 30.07 g of an object of density equal to

den301095 [7]

Answer:

$\boxed {\tt 20.317567567568 \ mL}$

Explanation:

The density formula is:

$d=\frac{m}{v}$

Let's rearrange the formula for $v$ . the volume. Multiply both sides by $v$ , then divide by $d$ .

$d*v=\frac{m}{v}*v$

$d*v=m$

$\frac{d*v}{d}=\frac{m}{d}$

$v=\frac{m}{d}$

The volume can be found by dividing the mass by the density. The mass of the object is 30.07 grams and the density is 1.48 grams per milliliter.

$m= 30.07 \ g\\d= 1.48 \ g/mL$

$v=\frac{30.07 \ g}{1.48 \ g/mL}$

Divide. Note, when dividing, the grams, or $g$ will cancel out.

$v= \frac{30.07}{1.48 \ mL}$

$v=20.317567567568 \ mL$

The volume of the object is 20.317567567568 milliliters.

Negative ions are usually formed from: metals nonmetals

Lelechka [254]

Non metals are electronegative in nature whereas metals are electropositive. A non-metal accepts electron and gains negative charge whereas metals lose eletrons and gains positive charge. Hence correct answer is non-metals. Hope this helps!
