Answer:

Use molar mass:)

Explanation:

3.62 mol of Sn (\frac{118.7gramsSn}{mol})=429.694

Since 3.62 has 3 sig figs, limit 429.694 to 3

= 430

Does a laboratory balance measure mass or weight
kolezko [41]
A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.

So the mass of the object can be found by dividing the weight by gravitational constant.

The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.

Hope that helps :)

At a certain temperature the rate of this reaction is first order in HI with a rate constant of 0.0632 s
kirza4 [7]

Answer:

28.037\ \text{s}

Explanation:

[A]_0 = Initial concentration = 1.28 M

[A] = Final concentration = 0.17[A]_0

k = Rate constant = 0.0632 s

t = Time taken

For first order reaction we have the relation

kt=\ln\dfrac{[A]_0}{[A]}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{[A]}}{k}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{0.17[A]_0}}{0.0632}\\\Rightarrow t=28.037\ \text{s}

Time taken to reach the required concentration would be 28.037\ \text{s}.

What is the correct balanced equation for the following equilibrium constant expression?
weeeeeb [17]
The correct answer is 3) 2CO2(g) ⇄ 2CO(g)  + O2(g)

this is the correct one because it is a decomposition reaction and all the number of atoms is equal on both sides.

there are 2 C atoms on both sides. 

and 4 O atoms on both sides.

and 1) the atoms numbers are equal on both sides but not correct as it not a

correct number as it has 1/2 O2.


and 2) CO2(g) ⇆ CO(g) + O2 

the number of O atoms is not equal on both sides of the equation.

we have 2 O atoms on the left side and 3 O atoms on the right side.

so, this not a balanced equation.

4) also not correct 2CO(g) + O2 ⇆ 2CO2

as it is not a decomposition reaction and the 2CO & O2 are as reactants not products.

so the correct answer is 3) 2CO2(g) ⇆ 2CO(g) + O2(g)
