Why do positive ions have a positive charge?​

Chemistry
1 answer:
Rudiy273 years ago
8 0

Answer:

Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged. Ionic bonding is the attraction between positively- and negatively-charged ions.

How many grams are in 1.3 x 1024 atoms of hydrogen?
olga2289 [7]

Answer: 4.32g

Explanation:

MM of H2 = 1 x 2 = 2g/mol

2g of H2 contains 6.02x10^23 atoms.

Therefore Xg of H2 will contain 1.3 x 1024 atoms i.e

Xg of H2 = (2 x 1.3 x 1024) / 6.02x10^23 = 4.32g

Which unit conversion allows you to convert 21.0 gallons into milliliters?
Romashka-Z-Leto [24]

79470.2mL

Explanation:

Given:

  Volume = 21gallons

  problem, convert to milliliters;

   

  gallons to milliliters

 1 liter = 1.057 quarts

1 gallon = 4 quarts

we can simply solve this by establishing and using a conversion factor of 1 ;

     

   1 gallon = 4 quarts

   1.057 quarts = 1 liter

   0.001L = 1mL

21gallons x \frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}  = 79470.2mL

we say;

From; \frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}

1gallon = 3784.2mL
