SiO2 + 4HF → SiFe + 2H2O write 5 possible mole ratios

Chemistry
1 answer:
aev [14]3 years ago
7 0

Answer:

Here's what I get

Explanation:

SiO₂ + 4HF ⟶ SiF₄ + 2H₂O  

The molar ratios are the same as the coefficients in the balanced equation.

Some of the molar ratios are

 SiO₂:HF = 1:4

SiO₂:SiF₄ = 1:1

SiO₂:H₂O = 1:2

  HF:SiF₄ = 4:1

  HF:H₂O = 4:2

 SiF₄:H₂O = 1:2

pickupchik [31]

Answer:

no it's not solid rather it's an aqueous

An example of gaining potential energy
aleksandr82 [10.1K]

Answer:

An example for gaining potential energy would be: A glass bottle on the top of a high shelf would have more high potential energy than a glass bottle on the middle or bottom shelf because it has a long way or more farther to fall down or brake.

Explanation:

Remember Potential Energy is the restored energy of an object has.

How many joules of heat are required to raise the temperature of 320.0 grams of water from 24.2°C to 50.8°C? Heat capacity of wa
balu736 [363]

Answer:

35750.4 Joules

Explanation:

Using the formula as follows;

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to the provided information,

mass (m) = 320.0 grams

c = 4.2 J/g°C

∆T = (50.8°C - 24.2°C) = 26.6°C

Q = ?

Using; Q = m × c × ∆T

Q = 320 × 4.2 × 26.6

Q = 35750.4 J
