Answer:

The 2 zeros after the decimal point

vitfil [10]4 years ago
5 0

Answer:

None

Explanation:

Numbers can only be significant in three ways.

1) Non-zero numbers

2) Zeroes between non-zero numbers

3) Trailing zeroes in a decimal. Only counts if there is a decimal point.

Since the zeroes are not trailing or located between two non-zero digits, there are no zeroes in 0.0079.

klemol [59]

Answer:

true

Explanation:

PV=nRT

The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant R is called the Boltzmann constant

Name two functional groups that contain ionic charges?
Alika [10]

The answer is:

carboxylate

and protonated amines

The explanation:

when

The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.

and about protonated amines:

-alkyl groups improve the basicity, aryl groups diminish it.

-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.

- Primary amines are basic functions which could be protonated to the  ammonium ion

29.0g silver combine completely with 4.30g of sulfur to form a compound. what is the percent composition of this compound?
Deffense [45]

Answer:

Percentage of silver and sulphur in the compound  is 87.08% and 12.91%  respectively

Explanation:

Given:

Amount of silver = 29.0 g

Amount of sulphur= 4.30 g

To find:

Percent composition of the compound=?

Solution:

\text { percent of compound }=\frac{\text { amount of element }}{\text { Total Molecule Mass }} \times 100

Total Molecule mass = amount of silver + amount of sulphur

Total Molecule mass = 29+4.3  

Total Molecule mass = 33.3g

Percentage of silver:

\text { Percentage of silver }=\frac{\text { amount of silver }}{\text { Total Molecule Mass }} \times 100

=>\frac{29.0}{33.3}\times100

=>0.8708 \times100

=> 87.08%

Percentage of silver:

\text { Percentage of silver }=\frac{\text {amount of suplhur}}{\text { Total Molecule Mass }} \times 100

=>\frac{4.30}{33.3}\times 100

=>0.1291\times 100

=> 12.91%
