How likely is it that a scientific theory is correct?

yan [13]

It all depends what theory it is most are supported by really good evidence but they just don't have all the evidence so it can't be proven a fact at that time

Determine the empirical formula of a compound containing 1.71 g of silicon and 8.63 g of chlorine.

Basile [38]

Answer:

The answer to your question is: SiCl₄

Explanation:

Data

amount of Si 1.71 g

amount of Cl 8.63 g

MW Si = 28 g

MW Cl = 35.5

Process (rule of three)

For Si For Cl

28 g of Si ------------------ 1 mol 35.5 g of Cl --------------- 1 mol

1.71g of Si --------------- x 8.63 g of Cl -------------- x

x = 1.71 x 1 / 28 = 0.06 mol x = 8.63 x 1 / 35.5 = 0.24 mol

Now, divide both results by the lowest of them.

Si = 0.06 mol / 0.06 = 1 molecule of Si Cl = 0.24 / 0.06 = 4 molecules of Cl

Finally

Si₁ Cl₄ or SiCl₄

2. A sample of oxygen gas is placed in a rigid 1.5L glass container at STP. If the gas is

sladkih [1.3K]

The new pressure : P₂ = 1038.39 mmHg

<h3>Further explanation</h3>

Given

1.5 L container at STP

Heated to 100 °C

Required

The new pressure

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).

So P₁ = 1 atm = 760 mmHg

T₁ = 273 K

T₂ = 100 °C+273 = 373 K

Gay Lussac's Law

When the volume is not changed, the gas pressure is proportional to its absolute temperature

$\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

Input the value :

P₂=(P₁.T₂)/T₁

P₂=(760 x 373)/273

P₂ = 1038.39 mmHg

Sample of 200mls of 0.5 sulphuric acid,was asked to produce 1.2M of the new solution.Calculate the volume of the new solution

AlladinOne [14]

Answer:

$V_2=83.3mL$

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the volume of the new solution by using the general formula of dilution:

$V_1M_1=V_2M_2$

In such a way, we solve for the final volume, V2, to obtain:

$V_2=\frac{200mL*0.5M}{1.2M}\\\\V_2=83.3mL$

Regards!
