PLEASE ITS URGENT! If some electrons are transferred from object A to object B,

Chemistry
1 answer:
maks197457 [2]4 years ago
8 0

Object A will have a positive charge since it is losing electrons. And object B would have a negative charge since its gaining electrons. For example, magnesium atom is object A and chloride atom is object B. Magnesium atom gives an electron away to the chloride atom. Therefore the chloride atom will have a negative charge of one and magnesium has a positive charge of 1.

The answer is A. Object A will have a positive charge.

Silver iodide powder has been used as an antiseptic and as an agent to seed clouds for rain. Silver iodide is 45.9% silver by ma
Dahasolnce [82]

Answer:

22.95g

Explanation:

Given parameters:

Percentage by mass of silver in silver iodide  = 45.9%

Mass of silver iodide given  = 50g

Unknown:

Mass of silver in silver iodide  = ?

Solution:

The formula of the compound is;

 Silver iodide  = AgI

       Since the percentage by mass of silver in the compound is 45.9%;

 Mass of silver  = percentage by mass of silver x mass of AgI

 Mass of silver  = \frac{45.9}{100} x 50  = 22.95g

A solution has a [Ag+(aq)] of 0.01 M. The chloride concentration in solution is 1 x 10-5 M. Based on the following reaction, ans
earnstyle [38]
 The value  of current  solubility  product  is calculated as  below

K =  (Ag+)( Cl-)

 Ag+  =  0.01 M
Cl-= 1 x10^-5M

K is therefore = 1 x10^-5 x 0.01 = 1 x10  ^ -7 M

The K obtained is greater  than  Ksp

that is    K>  KSp
 1x10^-7 >  1.7 x10 ^-10


will  precipitation  of AgCl form?

yes  the precipitation  of AgCl  will  be formed   since   K> KSP

The maximum contaminant level of copper (Cu) in drinking water as set by the the Environmental Protection Agency (EPA) is 0.0013
Mazyrski [523]

Answer is: concentration is 1.3 ppm.

Parts-per-million (10⁻⁶) is present at one-millionth of a gram per gram of sample solution, for example mg/kg.

d(Cu) = 0.0013 g/L; mass concentration of copper.

d(H₂O) = 1.00 g/mL; density of water.

m(H₂O) = V(H₂O) · d(H₂O).

m(H₂O) = 1000 mL · 1 g/mL.

m(H₂O) = 1000 g ÷ 1000 g/kg.

m(H₂O) = 1 kg; mass of water.

m(Cu) = 0.0013 g · 1000 mg/g.

m(Cu) = 1.3 mg; mass of coppper.

concentration = 1.3 mg ÷ 1 kg.

concentration = 1.3 mg/kg.

concentration = 1.3 ppm.
