12.01 amu

Work:

(12.000 × .9889) + (13.003 × .0111) = 12.01

turn the precents into decimals

Rank the four gases (air, exhaled air, gas produced from the decomposition of H2O2, gas from decomposition of NaHCO3) in order o

TEA [102]

Decomposition of sodium bicarbonate produces pure carbon dioxide and decomposition of hydrogen peroxide produces pure oxygen.
The amount of carbon dioxide in exhaled air is greater than that in regular air. Thus, the order is:

gas from decomposition of NaHCO₃ → Exhaled air → Air → gas from the decomposition of H₂O₂

What does lead ii acetate and hydrogen sulfide produce? and what type of reaction is it?

kati45 [8]

When Lead (II) acetate and Hydrogen sulfide react, they form Lead sulfide and Acetic acid. The reaction is a reduction-oxidation (redox) reaction.
The balanced chemical reaction is this:
Pb(C2H3O2)2 + H2S --> PbS + 2C2H4O2
And the net ionic reaction is this:
Pb2+ + S2- --> PbS

A sample of methane gas collected at a pressure of 0.884 atm and a temperature of 6.00 C is found to occupy a volume of 26.5 L.

Genrish500 [490]

Answer:

1.03mole

Explanation:

Given parameters:

Pressure = 0.884 atm

Temperature = 6°C = 273 + 6 = 279k

Volume = 26.5L

Unknown:

Number of moles = ?

Solution:

To solve this problem, we use the ideal gas equation:

PV = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

n = $\frac{PV}{RT}$ = $\frac{0.884 x 26.5}{0.082 x 279}$ = 1.03mole

A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?

AlexFokin [52]

Answer:

<h2>15 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

f is the force

m is the mass

From the question we have

$a = \frac{300000}{20000} = \frac{30}{2} \\$

We have the final answer as

<h3>15 m/s²</h3>

Hope this helps you
