Answer:

See explanation

Explanation:

Full molecular equation;

2NH3(aq) + AgNO3(aq) -------> [Ag(NH3)2]NO3(aq)

Full ionic equation

2NH3(aq) + Ag^+(aq) + NO3^-(aq) --------> [Ag(NH3)2]^+(aq) + NO3^-(aq)

Net ionic equation;

2NH3(aq) + Ag^+(aq) -------->  [Ag(NH3)2]^+(aq)

When Silver nitrate is mixed with a solution of aqueous ammonia, a white and cloudy solution was observed.

The atomic mass of chlorine is listed as 35.454 amu on the periodic table. It has two naturally occurring isotopes, Cl-35 and Cl
Fynjy0 [20]
X=percentage of Cl-35
(1-x)=percentage of Cl-35

35(x)+37(1-x)=35.454
35x+37-37x=35.454
-2x=35.454-37
-2x=-1.546
x=-1.546/(-2)
x=0.773

0.773=77.3/100=77.3%

(1-x)=1-0.773=0.227

0.227=22.7/100=22.7%

answer: the percentages are: 77.3% of Cl-35 and 22.7% of Cl-37.

Sakura tested the pH of several solutions. Which substances are acidic? Check all that apply. Cola-flavored soda: 2. 6 cranberry
Archy [21]

Cola-flavored soda: 2. 6 -Acidic

cranberry juice: 2. 9  -Acidic

dish soap: 7. 3  -Basic

pickle juice: 5. 5  -Acidic

seawater: 8. 0 -Basic

lye soap: 13. 0. -Basic

<h3>What is pH?</h3>

pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.

The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.

Below 7 are all acids and the above 7 are all basic.

Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

Marina CMI [18]

Answer:

Matter

Compound

Explanation:

Caffeine is NOT an Element, because it is formed by different elements (C, H, N, and O).

Caffeine is NOT an Isotope, because this only applies to elements with the same atomic number but different mass number.

Caffeine is Matter because it has mass and occupies space by having volume.

Caffeine is a Compound because it has a formula with a <em>definite constant composition</em> of different elements.

What is the total number of grams of h2o produced when 22 grams of propane undergoes complete combustion?
SSSSS [86.1K]
The combustion reaction of propane would be expressed as:

C3H8 + 5O2 = 3CO2 + 4H2O

To determine the mass of water that is produced from the given amount of propane, we use the mass of propane and the relation of the substances from the balanced reaction. We do as follows:

moles propane = 22 g C3H8 ( 1 mol / 44.1 g ) = 0.50 mol C3H8
moles H2O = 0.50 mol C3H8 ( 4 mol H2O / 1 mol C3H8) = 2 mol H2O
mass H2O = 2 mol H2O ( 18.02 g / 1 mol ) = 36.04 g H2O

Therefore, the mass of water that is produced from 22 grams of propane would be 36.04 g.
