How many moles of \ce{AgCl}AgClA, g, C, l will be produced from 60.0 \text{ g}60.0 g60, point, 0, start text, space, g, end text

lozanna [386]

Answer:

For 0.353 moles AgNO3, we'll have 0.353 moles AgCl

Explanation:

How many moles of AgCl will be produced from 60.0g AgNO3 assuming NaCl is available in excess.

Step 1: Data given

Mass of AgNO3 = 60.0 grams

Molar mass AgNO3 = 169.87 g/mol

NaCl is in excess, so AgNO3 is the limiting reactant

Step 2: The balanced equation

AgNO3 + NaCl → AgCl + NaNO3

Step 3: Calculate moles AgNO3

Moles AgNO3 = mass AgNO3 / molar mass AgNO3

Moles AgNO3 = 60.0 grams / 169.87 g/mol

Moles AgNO3 = 0.353 moles

Step 4: Calculate moles AgCl

For 1 mol AgNO3 we need 1 mol NaCl to produce 1 mol AgCl and 1 mol NaNO3

For 0.353 moles AgNO3, we'll have 0.353 moles AgCl

A sample of 8.11 g 8.11 g of solid calcium hydroxide is added to 38.0 mL 38.0 mL of 0.410 M 0.410 M aqueous hydrochloric acid. W

Andrews [41]

Answer:

The balanced chemical equation :

$Ca(OH)_2(s)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)$

Explanation:

When calcium hydroxide reacts with hydrochloric acid it gives calcium chloride and water as a products. The chemical equation is given as:

$Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

According to question, solid calcium hydroxde is added to 38.0 mL of 0.410 M of HCl solution, so the chemical equation can be written as:

$Ca(OH)_2(s)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)$

According to stoichiometry, when 1 mole of solid calcium hydroxide reacts with 1 mole of hydrochloric acid to gives 1 mole of aqueous calcium chloride and 1 mole of water.

A sample of oxygen gas (O2) has a volume of 7.51 L at a temperature of 19°C and a pressure of 1.38 atm. Calculate the moles of O

Maslowich

Answer: 0.43molO₂

Explanation:

The ideal gas law for moles is $n=\frac{PV}{RT}$ . If you did not know, R is the ideal gas constant, $0.0821\frac{L*atm}{mol*K}$ .

Since the temperature must be in Kelvin, we must convert our given temperature from ℃ to K. $19C+273=292K$

Now that we have the temperature converted to Kelvin, we can plug in our information to the ideal gas law for the number of moles.

$n=\frac{PV}{RT}$

$n=\frac{1.38atm*7.51L}{0.0821\frac{L*atm}{mol*K} *292K} =0.43molO_{2}$

$n=0.43molO_{2}$

Therefore, the number of moles is 0.43molO₂.

I hope this helps! Pls mark brainliest!! :)

How do mass and height of an object affect the gravititational potential energy

White raven [17]

Answer:

D. mass has a greater effect than height on gravitational potential energy

Explanation:

The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of gravitational potential energy the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.More massive objects have greater gravitational potential energy.
